Mulholland didn't create this dam to kill people. It is true that his team made mistakes but doesn't make him evil or money hungry. The video even explained that he had completed many other successful water infrastructure projects.
Construction just doesn't work the same way anymore though. There is no one person who takes responsibility, because projects are not the product of just one person anymore. In fact significant effort has been put into preventing a single person from having the kind of oversight and micromanaging capability as Mulholland had. The modern system is not without its faults, but it does mitigate to some extent the problems exemplified by this story. "Superstar" engineers can oversee the construction of incredible structures, but when they become distracted, overworked, or just plain stuck on a bad idea, the consequences can be devastating.
I am a retired engineer, not self taught, but professionally qualified, and worked on some very hazardous chemical installations. My worst nightmare was that something that I designed could cause a single death, nevermind hundreds. I managed 30 years with only minor accidents of slips trips and falls, for that I am extremely thankful.
Thank you for your recollection. I am a young engineer and will be getting my PE later this year. My worst fear is for my own design to harm anyone. Our current system of checks & balances on engineering design is built on a foundation of catastrophic failures, and we must be determined to not repeat history.
I was a roofing contractor for over 30 years. I done everything from hot tar almost every other type of roofing they had up to 2006. Most the time I ran about 6 men if busy during a hail storm then maybe 20 to catch up. In the whole time I had 2 men go to the hospital. Both were over drugs they got at lunch time. But even so very minor injuries. Just a er visit and released. Really it is a very good record for this type of work. Nothing like your danger point.
how often do we hear about the people taking full responsibility? mulhulland may have made mistakes that caused this, but at least he owned up to them. i'll give him credit for that.
It's a sad story; he was actually deeply emotionally affected by the failure of the dam. Reminds me a lot of the designer (mentioned in a recent video on this channel, in fact) of the suspended walkways in the Hyatt Hotel collapse, who lectured for years afterward to warn of his firm's mistakes.
From the Inquest: "A sorrowful Mulholland told the Coroner’s Inquest that he “only envied those who were killed” • He went on to say “Don’t blame anyone else, you just fasten it on me. If there was an error in human judgment, I was the human.”
I used to live in a mountain valley in California that had lots of streams and water until the kind folk in LA voted to have it diverted to them. Now that valley is a dried up crust.
Meh how the world works. Need to support a larger population who everbis in a smaller one just gonna have to deal with it. The lives of millions of course would weigh more than the lives of a few thousand in a small Townsend. Not to mention LA would also produce more tax money as well. Happens everywhere in the world. I can't say its right but I also can't say outright its wrong.
This disaster leveled my hometown of Fillmore. It wiped everything along the Santa Clara River Valley and took out the only bridge connecting Fillmore to Bardsdale, Moorpark for years. Bardsdale was (and still is) like a cluster of ranches, churches and homes, whereas Fillmore was an actual town with an active railroad. Without access to Fillmore, Bardsdale was going to have a hard time getting ordinary goods. So a suspendible foot bridge with a zipline was set up for folks to come and go across each side of the riverbed until a new bridge could be fully erected years later.
I'm in Bardsdale right now. It's amazing how little rise there is from the ranch down to the Santa Clara River. Hard to imagine the wall of water coming through. Was driving through Santa Paula the other day and my grandfather was pointing the height of the high water mark just below the second floor windows at the Isbell Middle School a quarter mile from the Santa Clara River.
@@sh-zs4oy hehe, unfortunately no there isn't one anymore. The zip line along with a suspendible foot bridge they used in the meantime stayed for years until a considerable replacent (y'know... a real bridge lol) was put in place. Today there is an actual concrete overpass
You make it sound like you witnessed the event or were directly affected by it. I got confused for a sec because I was like “wait a minute this dude can’t be over 120 years old” 😂
You’d think but we take mechanics that show significant prowess and allow them to become “engineering techs” and their job is identical with the engineers with degrees
@@suspicioustumbleweed4760 an engineer where I work has to go through a 2+ year long period where they solve the problem and then it all must get second checked until they take a test and pass then they can be the only ones who sign off on some thing. Unless it’s critical or a redesign in which case it needs two or three signatures each of which has their own double check.
Chief engineer... In USA, you did not hesitate to vote a self taught idiot to PresidenT! And lots of people believe him to win the second election... :-)
I heard (from Caitlin Doughty's video) that the "tombstone" was destroyed after a teenager fell off it while doing teenager things and died. Kinda cursed.
Actually it was basically the geologists that warned about the site issues, but they were ignored as were the issues encountered during the remediation efforts for the geological material in the abutment. The essentially problem was that the rock, which is multiple units of the huckleberry ridge ash flow tuff (from Yellowstone), is very porous, and without anything done, would allow water to flow through it and lead to piping, undermining the earthen dam. The proposed solution was to pump grout into the abutments to seal the pores. However, after several times the amount of grout was pumped into the rock that was estimated was required for this task, and despite the fact that the rock was still freely accepting more grout (indicating large volumes of pore space still existed), they stopped grouting and filled the dam. Predictably, the water quickly found pathways under and around the dam, through the rock, and began runaway piping and removal of earthen dam material leading to failure. The center of the earthen dam still remains, you can see the layered construction of it, and I believe it was determined that no fault in construction of the earthen portion was made, it simply had no chance to begin with. Ive been there as a geologist to study the huckleberry ridge tuffs unrelated to the dam collapse, and even climbed down the abutments to get samples (they're so fresh, thanks US bureau of reclamation!) and saw the grout/cement pumping holes used during construction.
Water is an amazingly destructive force if left unchecked. Anyone who doesn't think so should go visit the grand canyon - it's pretty breathtaking what any flow of water over time can do!
@@DocNo27 I actually live about a 10 min drive away from the disaster site and after they destroyed all the bits that where left, it turned into a pretty cool ruins with a dope stream cutting through
The L. A. Bureau of Power & Light (I believe they changed their name in April 1940?) to Los Angeles Department of Water & Power, dug a big "grave" downstream and then dynamited the "tombstone." Lots of people went out to see this. The hulking remains of the dam brought lots of sightseers to the disaster site. Not only was the death of a teenager (who had a snake thrown at him by his friend and scared him to fall off the structure) a reason for ditching the tombstone but it was a constant reminder in a very bad public relations way, of the DWP's policy failure.
The history of Mulholland's aqueduct is sordid in itself. The mentioned "disgruntled" locals basically had their land stolen and seized or otherwise cheated from them for it. It plays neatly into the current history of the region where the coast and the inland portions of the state have a serious political divide, especially over water, to this day.
Yeah, I live in the interior of California and everyday I hope and pray that all the costal cities fall into the pacific and that Sacramento turns back into the swamp it was.
And North California has to give up water to these SoCal dipshits who decided to live in a desert. We here in the North have a smaller population so politically,we're screwed by LA.
The politics of California's water supply have always been crooked. Now the lake where the water started from is a dry bed and LA County has to spend millions to put sprinklers over the dry bed to keep the dust (Which was making locals sick) from polluting the air.
@@Davivd2 Agreed,those rich fuckers in LA are now ruining North Cali (and a bit of South Oregon) by making a portion of it into the Cascade Monument just so some hikers can go on the Pacific Crest trail once a year and act like they're "mountain men" all while screwing us locals hard and indirectly causing more fires. I hope part of LA gets caught in a huge wildfire.
I think this disaster is referenced in the film "Chinatown" with Jack Nicholson, when the engineer at the town hearing refuses to build another dangerous dam near the beginning of the film. It's a great crime noir story takes place with the backdrop of LA's shady water rights history, which involved screwing a lot of farmers and landowners out of their property,
If you want a real look at the drama of the water wars in the west check out "Cadillac Desert: The American West and Its Disappearing Water" - I think it's a little too biased against the US Bureau of Reclamation, but it's still a thorough and fascinating look at the politics and money of water in the southwest. Decisions made and policies set in the 20's and 30's due to people like Mulholland are still causing fallout today (and perpetuating stupid shit like growing Almonds in the desert - talk about wasting water!).
@@DocNo27 Cadillac Desert is a good watch (can be found on RUclips) and I agree with your take on the biased view. On the almond side, much of the Owens valley was self-sufficient farming land until LA diverted the water from the region thus some of the farmers moved to where the water ended up.
As a former resident (1960!) of LA, I lived downstream of another dam disaster, the collapse of the Baldwin dam in 1964. This was an interesting disaster caused by a geologic fault, subsidence by the extraction of oil, and a very dubious method of sealing the floor of the reservoir with asphalt. While the total destruction was less than St Francis, a business district and quite a number of homes were washed away. Great video!
This channel covered the Baldwin hills dam flood! I grew up outside of LA and can’t imagine a catastrophic failure on this scale, wiping out dense neighborhoods…
I live a few minutes away from this dam. This is the best documentary that I've seen on the dam. You are very thorough. I will add one bit of information that I saw from another documentary. Mullholland had instructed that the dam would be built with a higher quality of concrete than what was actually used, which adds another component of potential failure into the mix. The density of the concrete used was found in later testing not to be up to the specs laid out by Mullholland. That being said, I think that even if all of the failures of this dam were removed during construction that it would only be a matter of time before the dam broke anyways. The canyon that the dam was built in goes back for miles and about every 6 years or so we get some serious flooding. I'm not an engineer, but I can't imagine that it would have held up under one of these floods that would have backed up a massive amount of water volume up the canyon.
@@PlainlyDifficult gonna add to this and say I've taken the official tour of this dam twice with the Santa Clarita Historical Society, and this video was more informative then their annual tour
In order to save money for cement preparation, the actual sand found in the bottom of the site was mixed with lime and used in the actual dam. Part of the problem, too, was the base of the dam intersected an ancient geological landslide. Directly beneath the dam was very hard conglomerate. Unfortunately, conglomerate becomes lose and muddy when mixed with water and its density flows through your fingers. What was not mentioned was that the Dam Keeper's son was also lost that night. Bodies of either were never found and presumably washed out to sea.
@@765kvline Thanks for the extra info. I enjoy learning more and more about this incident as the years go by and a drive by the few chunks of concrete that still exist on my way into town.
I was 9 years old, but I lived through the Teton Dam disaster and remember it vividly to this day. This story has always been a horrifying fascination to me.
Good morning from morning land! Look up the Johnstown Flood. A dam broke because idiots were idiots and people died. I grew up about 25 miles from the site and we learned about it in school... Apparently it was one of the worst disasters involving human error and dams. But this one in the video DEFINITELY seems way worse... Eitherway, Johnstown Flood would make for a great video
Way worse in terms of lives lost... I live near the Johnstown area and the flood museum is an amazing place to visit. Just like the st Francis dam you can visualize where the lake was and the massive scale of the failure
Yes, this killed over 2,000 people and the cause was just plain negligence by a hunting and fishing club for millionaires (basically a modern day country club for the extremely wealthy). They ignored warning signs, altered the dam cheaply to save money when trouble started showing, and this one should be a 9 or 10 on the patented Plainly Difficult disaster scale.
"self-taught engineer" - Red flag!! I am an engineer myself and I've met some really good people already who are mostly self-taught. Physicists as software engineers for example. However, despite their superior experience compared to my (back then) Junior engineer experience, I noticed every once in a while that these people are lacking some theoretical background. I really loved working with these guys, because I could learn from their experience. However, the sometimes missing theoretical background stays - and that's something that might be acceptable for a software engineer, but not so much for a civil engineer... And improvising on a dam project also is the next big red flag...
my grandfather was a coal miner who decided to become a self-taught electrician and carpenter, we've had trained electricians and construction people come into the house and have to step outside for a few minutes to recompose themselves at the eldrich horror of somehow functional how-the-hell-is-this-house-still-standing-and-not-on-fire level techniques he used to piece things back together on his own. sometimes self taught is a good thing i've worked with a lot of excellent self-taught artisans and craftspeople at the gallery and shows over the years, but sometimes that missing professional knowledge of things like WHY aluminum wire should not be patched directly into ancient knob-and-tube wiring and be held together with electrical tape and prayers can be kinda important in the big stuff. self-taught piano player, sure why not. self-taught dam engineer, noooope!
Like everything, it depends. I'm an engineer of 30 years experience and honestly the most competent engineer I ever worked with was self taught, but he is no ordinary man, being also an accomplished writer and entrepreneur, and an expert in the arts as well as the sciences. On the other end of the scale, you won't have to go far to find qualified yet incompetent people. The real problem is that there were no checks and limits in place to verify that this design was good. No single person's incompetence should ever be able to initiate a disaster, if it can then the system is broken.
I'm an industrial engineer, but I only went to university after working as a machinist for a couple of years. I don't know if it's the same in civil engineering, but as a machinist we would get drawings of stuff that couldn't be made, designs of mechanisms that we knew couldn't possible work. Engineers were certainly not well respected. Once I was in university I understood why. Most of them they came from an entirely theoretical education, had never really worked on any machines, did barely know what a lathe or milling machine was. When they did system analysis their calculations where entirely theoretical. They could calculate PID values, but couldn't tune a servo system in reality. And most of them got their degree while being incompetent beyond believe.
@@slome815 Well, it's not their job to actually build or maintain it. However, there is something like "Design for manufacturability" or "Design for maintainability", etc. ("Design for X" if you want everything). And that is still not taught at every university and also the extend in which it is taught is often still not sufficient. But as I said: It's not the job of an engineer to actually build that stuff. However, an engineer who develops products should always take into account that this needs to be manufactured later by someone. If you break your fingers during assembly of the prototype, it is certainly not ready for series production... I know that engineers are often not well regarded, because they can't assemble or maintain the thing that they constructed, but mechanics often don't see that mechanics are also no gods. If mechanics could do the job of an engineer, we wouldn't need to have engineers study for 3 or 5 years at an university. A mechanic can for sure design simple things, but for sure he can't design a car that meets modern safety and efficiency standards while keeping the material costs as low as possible. People just need to understand what their job is and what they can't do, but other people can. Only then can a team work efficiently - when everybody values the skills of other team members...
@@fr89k Frankly, the last 2 years of my master's degree were nearly useless. I learned a lot more usefull things about designing, strenght calculations, PID, fluid mechanics in my professional bachelor years then I ever did when I went for my masters degree . The problem is not that many engineers can't maintain or build their designs, that's a given. The problem is that many engineers can't properly design a product. We had to make constant calls about dumb designs. (do we really need that 10µm tolerance on that handwheel?, Does that 15cm deep wheight saving pocket really need a 0.5mm corner on all sides.) The answer was usually, "oh I didn't think it mattered." And about safety. If you ever have been involved in a risk analysis to get a product CE rated you know how much of a joke it really is. After a couple of years working as an engineer I was so tired and dissapointed by the endless meetings about minor design changes and the lack of common sense of my bosses, that I quit and went to work a a CAD and machine shop teacher. A lot less pay, but at least I sometimes get the feeling I'm actually getting something done. Self thought engineers can be just as good. In fact some of the best engineers were self thought: James Watt, Tesla, Edison, Henry Ford and the Wright brothers were all self thought.
I live about 12 miles away from the disaster site (in Valencia, CA) and always take people for a hike that visit me in that area and tell them the story. This is the best video documentary I’ve seen on this disaster. I love your videos in general!! Thanks :)
I mean, it was admirable in this situation, but go read about him. Mulholland was a sophisticated politician and essentially destroyed the Owens Valley economy over water rights. A complicated figure at best.
@@OnlyTakk I know well if him. He was despicable in many ways. Anyone driving down 395 can tour the area he exploited. Without him LA as we know it might not exist. None the less, the buck stopped with him. That makes him honorable in my book even if his values were different than mine. That is why T**** can never be considered as having been honorable.
@@archstanton_live What I find impressive in him was his ability, as a self-taught, self-made man to do all of these things-impressive, great, and terrible all mixed.
I have read this story many times and I strangely always come away with an appreciation and respect for Mulholland. The way he accepted full responsibility instead of blaming those in charge of the construction is refreshing. I can only imagine that a similar incident nowadays would result in an endless circle of finger pointing. I also respect the fact that he was self taught and was so prolific in his career. I think his life should be celebrated in the civil engineering community instead of this one disaster defining him. Without Mulholland the city of Los Angeles may never have grown to be one of the largest residential areas in the country.
From the last slide in Dr. Roger's Presentation: "REQUIEM FOR MULHOLLAND " • Like any person, Bill Mulholland had weak points in his character. • His thirst for thriftiness was one of these flaws, but that same trait allowed Los Angeles to build its municipal infrastructure AHEAD of its burgeoning population, at rock bottom prices • He had an enormous capacity for innovation; getting difficult projects completed on-time and on-budget. • Engineers of that era tended to underestimate the complexities of pore pressure response, especially, on concrete dams • He had the depth of character to accept responsibility for shortcomings in the dam’s design and construction which very few people at the time fully comprehended :
To boot, From all I have read about the issue, is that Mulholland did not get an Engineering degree. His degree was for another engineering specialty. But because he was already Chief of Works, the oversight was not noted. He was a very Big Shot before the catastrophe.
As a man in a white lab coat holding a clipboard, I support this takeaway. We just run the numbers and speak the facts - it's not our fault if the idiots in the C-suite choose to ignore our advice and think that the laws of physics care about their wanting to save money!
This disaster was also covered in depth by Ask a Mortician on RUclips and the two of you are literally the only people I’ve heard talk about it. Seems odd it’s not more well known!
I've seen a few. It was an actual TV documentary that brought my attention too this incident though, and it was the thing that was on my mind as the dam above my town was having issues.
I must have seen over a half-dozen docs on this disaster. It was Mulholland, after all. They even went over this disaster in Ken Burn's "The West". It's a very well known event.
The moment I heard "self-taught", I knew what kinda failure this would be. Not that that's innately a red flag, just that it's the sort of thing one only brings up ominously
A self-taught engineer would never fly today. Even comparatively simple things like culvert design would require a degree. This could have only happed in 1920s America.
@@NetAnon that's because at the start of his career the US was still recovering from the civil war and there were no universities that specialized in engineering or geology. I find it inspiring that he learned from trial and error.
It's also worth considering the state of the field at the time. What an "engineer" needed to know in the 1910's and 20's was a long way from the amount there is to learn today. I agree that you shouldn't let a "self-taught" anyone direct a major public project, but some of the things we teach as textbook engineering failures today hadn't happened yet when this was built.
@Acme Inc. American Healthcare is over priced and the treatment side is underfunded. Most of the cost discrepancy between American and other nations healthcare is in administration, middlemen for insurance, and inflated drug prices. I hope for a socialized healthcare system in the next 20 years as that would indeed lower costs of administration and healthcare in general, it would also point to improvement towards the overall political climate and a willingness to pass more progressive policies.

My dad and I hiked there around 2000, during a period when nobody cared about it anymore. At that time the road through the canyon went right through the former dam itself. Today, the road has been moved westward and under the west wing of the former dam. It’s an amazing place to explore and visualize where the dam was and the destruction left behind.
Incredible to read all of this admiration for Mulholland. I’m not sure what my favourite Mulholland moment was; draining Owens Valley creating a carcinogenic dust bowl that will continue to blight the entire west coast of the US, or ensuring that vital farmland in the north of california is imperilled due to water exporting. Come the fuck on.
He had drive, ambition and determination. He became a self-taught engineer. And when he accidentally caused a massive disaster, he admitted responsibility and retired. At which point he was already in his 70’s. He was a man of great character. That’s why people admire him. I know nothing about his personal flaws or the massive damage his polices have caused. Both of which I am sure are long lists.
@@Erakius323 Admitted fault and retired... at the end of his life when he had nothing to loose. Not very impressive. Admitting fault is the bare minimum one should do. It's not praise worthy.
@@Erakius323 the city of LA hired him to steal water and that’s what he did. They wanted a self taught engineer because a real one would’ve told them no.
Mulholland caused every one of those deaths through his arrogance and corner-cutting; he was warned, he was told when the failure began, and still he did nothing. Negligent mass homicide. Depraved indifference. He gets no respect from me. ~ fifth generation native of the Los Angeles basin.
I absolutely love your videos, which is why I want to provide a bit of criticism: I feel like it would be helpful to include 3 types of maps when you say "which is about here on a map": Show where the country is, show where the region is, and show the local area. In a lot of videos but especially this one it's really hard to tell what the map is showing or to get a concept of what it's near. In archaeological contexts we use multiple maps so I thought it would be prudent to suggest. Love your content as always, cannot wait to continue learning with your next video.
I read "Man Made Disaster" in 1964 in junior high school and arranged to have my brother drive us up to the dam site. It has changed a good bit over the past 57 years. First, we drove up the old road, and it was clear where the dam was because the terrain to the north of the site was lush, green and wooded. The area below was still scoured and nearly barren. Of course, it had only been 36 years since the disaster. The wing wall was intact, and the steps of the "tombstone" were more visible. We brought back a chunk of concrete from one of the downstream sections. We had also talked our way into Powerplant # 2 during our 1964 trip. We saw the transformer that was wrenched out of the basement and tossed down the canyon, fished out, welded back together and re-used. I went back in the late 1980s. I hooked up with a Boy Scout troop and their scoutmasters, one who had a copy of the book. It was interesting to be among young men who were my age when I first saw the dam. It was clear that the wing wall had been demolished with explosives, not natural weathering. We went together to San Francisquito Powerplant # 1 and had a fascinating tour. The Pelton Wheel generators still had their "50 Hz buckets", designed to generate 50-cycle power that ran Los Angeles until the early 1950s. I have visited the ruins of the South Fork Dam above Johnstown, PA, and, at the end of the summer, I am going on a military history tour in Belgium and France, then flying to Italy to see the Vajont Dam, the site of the October, 1963 landslide that sent a 750' tsunami down a narrower canyon, killing over 3,000 people. I have long been haunted about the St. Francis Dam. I will return sometime, in the next few years,
Mulholland's famous quote about the disaster: "Whether it is good or bad, don't blame anyone else, you just fasten it on me. If there was an error in human judgment, I was the human, I won't try to fasten it on anyone else."
I first had an inkling of this disaster many years when we visited a cemetery in the Santa Paula area. We started to realize the abnormally large number of burials in March 1928. There were many families with the same date of death. I later heard of this disaster from a friend. Such a sad situation.
I really enjoy your dam videos. I worked at a hydro electric power station and part of my job was inspection of the dam twice a week which was much larger than this one, it was built in the 70s before computer simulation so they built a large scale model of the entire dam and catchment, filled it with water etc. There were two cracks in the dam, both about 2/3 of the way up on each side on the side not facing the water, they didn't leak and there was no concern about them as the scale model did exactly the same thing and it was expected to happen, amazing engineering for the time.
It kinda makes sense though, you partition a volume with a large surface area that varies with elevation into smaller 'slices' sort of like a Riemann sum. It's dumb, but also seems to be pretty practical and intuitive.
@@HendrikTheThird and easily manipulated. Measure the volume of a salad bowl, then a bread tray, if they have the same surface area the volume will vary thus the weight will vary considerably. The difference between 3 000 000 m3 and 4 000 000 m3 is a a million tonnes. An important calculation I suggest. Bernard appears in the dictionary but no description of his feats.
Great content as usual but a note about the vocalization itself. I much prefer this style than the ‘uptalking’ vocal fry way that others have been read. It’s almost like you took it down a notch and it comes off SO much better. So very much better. Please do them all like this, this was easy to listen to and understand despite being a very disturbing story. Just on a technical level, this was really good.
My great-grandfather was working for Edison in the camp below the dam that day. The dam failed due to multiple factors according to some more recent reports. One of the sides of the valley the dam was built on was the location of an ancient fault line that was only discovered due to more modern technology. The engineering knowledge at the time was not advanced enough to fully account for all factors of construction like concrete contraction and hydrostatic pressure. Mulholland also did not just quietly retire, when he first heard of the dam collapsing he was absolutely crushed. He never forgave himself for the damage he caused. He died after living for years with the crushing regret of what had happened. He was a brilliant visionary who helped Los Angeles develop to what it is today, but circumstance and the prestige he earned as a prominent figure placed him in a situation that was beyond his skills without realizing it. What ultimately happened robbed my father and his siblings of a grandfather long before they were born, but it would be unfair to lay the blame entirely on him.
I didnt know about this until I saw Caitlin Doughty's video "The Massive LA Disaster You've Never Heard Of" and honestly I never heard of this incident at all. it seems like an incident that seconds from disaster would have covered
My favorite example of a great dam in the wrong place is Vajont Dam. I would love to visit it and try out my Italian there. Such a tragedy on so many levels. What an incredibly well built dam it was! However, it is nearly inconceivable to me that so many warning signs had been ignored and construction proceeded anyway. The death and destruction was horrendous--just as St. Francis, Teton, Johnstown and other calamities. Engineering hubris in the face of the obvious is a major factor in bridge, dam and building catastrophes.
“Exacerbated” is a fun word to say. You have all the sounds. With a little practice, you could teach your brain not to default to the easier “exaggerated.” Although both fit, disasters are always exacerbated by something, and Plainly, no exaggeration is needed to display the horror of the St. Francis dam failure.
That's a darn curious choice of hill upon which to plant the flag of pedantry when the narration on this video contains several actual crimes against the English language, such as "analysis-es", "monumentous", and "Mulholland raised through the ranks" :)
Caitlin Doughty did a good video on this as well. Combining Plainly Difficult's video and hers, you get a really indepth understanding of what happened here and how it affected people then and even now.
Yes - it's more than a little biased in it's hatred of the US Bureau of Reclamation, but it's still a detailed and fascinating account - a book that anyone who lives in the American Southwest should absolutely read.
@@DocNo27 the reason for the percieved bias is that reclamation has failed in all its projects to paybfor themselves by genetating electricity and charging money for the water... Never recoverd the cost of any project... Though all the proposals submitted claimed they would pay for themselves..
If anyone is interested in the human side of this story, I suggest checking out Ask A Mortician's video on the same subject. Thanks for such a well researched video Plainly Difficult.
Hmmm. I wonder if I haven’t heard as much about this one before because Mr. Mullholland took responsibility. Normally companies and people try to pass the blame.
Great video! You mentioned the uplift failure but didn't mention why the center section did not fail... Uplift was a very new and theoretical concept at the time and mathematically showed that concrete dams could not use the same weight-to-vertical ratios as earthen dams because mud slurry is more dense than concrete. Earthen dams don't suffer from uplift failure since they are not a single unit structure like concrete dams are. Not to mention the (water-soluble) limestone veins, reported in the geological surveys at the foundation that were ignored. The St Francis damn was built with a somewhat new, uplift-relief design of vertical columns built within the center section. Unfortunately this design concept came to be after the abutments (left and right side) of the damn were already complete. The center section (the tombstone) DID have uplift-relief columns installed and did not become buoyant which is why it survived while the previously constructed abutments (without uplift-relief columns) did not.
Self taught engineer, overseeing massive civil projects Guess he incrementally completed larger and larger projects n they just figured he hasn't killed anyone yet....must be fine 👍
Right...you should look him up its a fun read. He's self taught but he's quite the brilliant person. A human error is a human error no matter what degree you have or how long you studied. Just look at Malpasset dam. I'm not excusing his action that leads to the death of hundreds, but don't discredit the man of his achievements and capabilities.
There have been highly professional engineers who didn't ignore the rules of mechanical stress but simply forgot the lessons in their attempts to trade appearance for structural integrity. Leon Moisseiff was a "professional," not self-taught, and had many successful bridges under his belt until the Tacoma Narrows 1940 Bridge took him down.
Acre-feet is a real thing in hydro engineering. It is a volume of water that covers a one-acre area to a depth of one foot. It's about 1/3 of a million gallons.
Unbelievable. I'm 49 and know my imperial units fairly well but it was a new one on me. Just when you think the non-metric system can't get any sillier. I'm surprised they didn't use bushels.
YAY! My Favorite man made disaster. I first heard of this from the book and PBS movie "Cadillac Desert", which is about how the Owens Valley, once the jewel of agriculture in California, was robbed of its water by William Mulholland and pals. I was then fortunate enough to live in the LA area around the turn of the century, and got to 4x4 through the area of the dams remains on several occasions. You can actually drive right through the where the dam was on San Fransiquito Canyon road. Its a bit hard to tell where things were at first, but you can still see the foundation of the dam there and there used to be giant chunks of the dam around the area. There was also a tall tale about how, at the moment the dam failed, there was a van full of gold driving across it carrying the pay for the army or something, and it was never found. While I mourn the senseless loss of life, I'm still fascinated by this engineering disaster. I also watched another documentary about the dam, which concluded that there was a rift in the embankment from a long ago earthquake, that they could not have known about then, as they didn't have ground piercing radar back then, and it was most likely the cause of the landslide and subsequent failure of the dam. Wish I could remember where I saw that. Great work as always!
It's worth noting: the area chosen was totally unsuitable for a dam. the lower portion of the western side of the abutment was composted of mica and schist, with talc mixed in. this ran all the way up the eastern hillside. basically, the whole place was a sieve, and the dam behaved like it. it was in a vice, being squeezed by hydrostatic uplift from the bottom and the eastern side. in some ways it s a miracle that it lasted that long.
Every year, on the anniversary of the dam’s failure, groups of people visit the site and sit in silence at the exact time of the failure. Kind of haunting. Traveling up the canyon, you can see the destructive remnants. Parts of the canyon are steep and narrow, meaning many had no chance of escaping a wall of water over 100 feet high.

Speaking of significant dam failures, the Malpasset (France) dam disaster is worth to be given a look to.
The fact that Mulholland took full responsibility and retired is just so foreign in this era. He deserves some respect for that.
I had the same exact thought.
the fact that noone was punished for killing 400+ people out of greed an negligience put up a fine example for today.
@@methanbreather if you didn’t say it I was gonna. Sure saying it’s your fault is fine, but there justice for the victims
Mulholland didn't create this dam to kill people. It is true that his team made mistakes but doesn't make him evil or money hungry. The video even explained that he had completed many other successful water infrastructure projects.
Construction just doesn't work the same way anymore though. There is no one person who takes responsibility, because projects are not the product of just one person anymore. In fact significant effort has been put into preventing a single person from having the kind of oversight and micromanaging capability as Mulholland had.
The modern system is not without its faults, but it does mitigate to some extent the problems exemplified by this story. "Superstar" engineers can oversee the construction of incredible structures, but when they become distracted, overworked, or just plain stuck on a bad idea, the consequences can be devastating.
I am a retired engineer, not self taught, but professionally qualified, and worked on some very hazardous chemical installations.
My worst nightmare was that something that I designed could cause a single death, nevermind hundreds. I managed 30 years with only minor accidents of slips trips and falls, for that I am extremely thankful.
This might be bit too little but thank you for the hard work you have put in
Ya seriously thanks mate
Thank you for your recollection. I am a young engineer and will be getting my PE later this year. My worst fear is for my own design to harm anyone. Our current system of checks & balances on engineering design is built on a foundation of catastrophic failures, and we must be determined to not repeat history.
I was a roofing contractor for over 30 years. I done everything from hot tar almost every other type of roofing they had up to 2006. Most the time I ran about 6 men if busy during a hail storm then maybe 20 to catch up. In the whole time I had 2 men go to the hospital. Both were over drugs they got at lunch time. But even so very minor injuries. Just a er visit and released. Really it is a very good record for this type of work. Nothing like your danger point.
Where were you at in 1920? 😩 lol jk. Times were just different back then. OSHA prolly became a thing because this disaster. Lol
how often do we hear about the people taking full responsibility?
mulhulland may have made mistakes that caused this, but at least he owned up to them. i'll give him credit for that.
I was going to say the same thing
or even any responsibility?
Today? Virtually never. Look at the people who are responsible for the lead leaching in Detroit.
It's a sad story; he was actually deeply emotionally affected by the failure of the dam. Reminds me a lot of the designer (mentioned in a recent video on this channel, in fact) of the suspended walkways in the Hyatt Hotel collapse, who lectured for years afterward to warn of his firm's mistakes.
From the Inquest: "A sorrowful Mulholland told the Coroner’s Inquest
that he “only envied those who were killed”
• He went on to say “Don’t blame anyone else, you just
fasten it on me. If there was an error in human
judgment, I was the human.”
I used to live in a mountain valley in California that had lots of streams and water until the kind folk in LA voted to have it diverted to them. Now that valley is a dried up crust.
Down side to majority rule. The big cities get what they want at the cost of rural communities
@@AlexPope Then at the slightest problem they up and leave and do it somewhere new.
“The kind folk in LA”...Just LOL at that :-)
Meh how the world works. Need to support a larger population who everbis in a smaller one just gonna have to deal with it. The lives of millions of course would weigh more than the lives of a few thousand in a small Townsend. Not to mention LA would also produce more tax money as well. Happens everywhere in the world. I can't say its right but I also can't say outright its wrong.

This disaster leveled my hometown of Fillmore. It wiped everything along the Santa Clara River Valley and took out the only bridge connecting Fillmore to Bardsdale, Moorpark for years. Bardsdale was (and still is) like a cluster of ranches, churches and homes, whereas Fillmore was an actual town with an active railroad. Without access to Fillmore, Bardsdale was going to have a hard time getting ordinary goods. So a suspendible foot bridge with a zipline was set up for folks to come and go across each side of the riverbed until a new bridge could be fully erected years later.
I'm in Bardsdale right now. It's amazing how little rise there is from the ranch down to the Santa Clara River. Hard to imagine the wall of water coming through. Was driving through Santa Paula the other day and my grandfather was pointing the height of the high water mark just below the second floor windows at the Isbell Middle School a quarter mile from the Santa Clara River.
Cool comment
@@sh-zs4oy hehe, unfortunately no there isn't one anymore. The zip line along with a suspendible foot bridge they used in the meantime stayed for years until a considerable replacent (y'know... a real bridge lol) was put in place. Today there is an actual concrete overpass

The Teton dam failure in Idaho is another good one. Surveyors said "not a good spot for a dam. Government: build it anyway!
The USBR hasn't built a major dam since 1976.
Actually it was basically the geologists that warned about the site issues, but they were ignored as were the issues encountered during the remediation efforts for the geological material in the abutment. The essentially problem was that the rock, which is multiple units of the huckleberry ridge ash flow tuff (from Yellowstone), is very porous, and without anything done, would allow water to flow through it and lead to piping, undermining the earthen dam. The proposed solution was to pump grout into the abutments to seal the pores. However, after several times the amount of grout was pumped into the rock that was estimated was required for this task, and despite the fact that the rock was still freely accepting more grout (indicating large volumes of pore space still existed), they stopped grouting and filled the dam.
Predictably, the water quickly found pathways under and around the dam, through the rock, and began runaway piping and removal of earthen dam material leading to failure.
The center of the earthen dam still remains, you can see the layered construction of it, and I believe it was determined that no fault in construction of the earthen portion was made, it simply had no chance to begin with.
Ive been there as a geologist to study the huckleberry ridge tuffs unrelated to the dam collapse, and even climbed down the abutments to get samples (they're so fresh, thanks US bureau of reclamation!) and saw the grout/cement pumping holes used during construction.
@@samwise1790 thanks for the explanation. Anyone who needs a more complete description should read “Cadillac desert”.
@@samwise1790 really the usbr just wanted to make sure you had fresh samples. Glass is half full! :)
@@nicholasbrown5013 departments of transportation in any state are a geologists best friend, highway roadcuts are a fantastic tool!
The picture of the dam afterwards is insane, the massive scale reduced to a tooth of concrete completely bypassed.
Water is an amazingly destructive force if left unchecked. Anyone who doesn't think so should go visit the grand canyon - it's pretty breathtaking what any flow of water over time can do!
@@DocNo27 I actually live about a 10 min drive away from the disaster site and after they destroyed all the bits that where left, it turned into a pretty cool ruins with a dope stream cutting through
The tombstone is honestly one of the most chilling things I've ever seen. It's so massive.
The L. A. Bureau of Power & Light (I believe they changed their name in April 1940?) to Los Angeles Department of Water & Power, dug a big "grave" downstream and then dynamited the "tombstone." Lots of people went out to see this. The hulking remains of the dam brought lots of sightseers to the disaster site. Not only was the death of a teenager (who had a snake thrown at him by his friend and scared him to fall off the structure) a reason for ditching the tombstone but it was a constant reminder in a very bad public relations way, of the DWP's policy failure.
The history of Mulholland's aqueduct is sordid in itself. The mentioned "disgruntled" locals basically had their land stolen and seized or otherwise cheated from them for it. It plays neatly into the current history of the region where the coast and the inland portions of the state have a serious political divide, especially over water, to this day.
Yeah, I live in the interior of California and everyday I hope and pray that all the costal cities fall into the pacific and that Sacramento turns back into the swamp it was.
The movie "Chinatown" covers this topic fairly well.
And North California has to give up water to these SoCal dipshits who decided to live in a desert. We here in the North have a smaller population so politically,we're screwed by LA.
The politics of California's water supply have always been crooked. Now the lake where the water started from is a dry bed and LA County has to spend millions to put sprinklers over the dry bed to keep the dust (Which was making locals sick) from polluting the air.
@@Davivd2 Agreed,those rich fuckers in LA are now ruining North Cali (and a bit of South Oregon) by making a portion of it into the Cascade Monument just so some hikers can go on the Pacific Crest trail once a year and act like they're "mountain men" all while screwing us locals hard and indirectly causing more fires. I hope part of LA gets caught in a huge wildfire.
I think this disaster is referenced in the film "Chinatown" with Jack Nicholson, when the engineer at the town hearing refuses to build another dangerous dam near the beginning of the film. It's a great crime noir story takes place with the backdrop of LA's shady water rights history, which involved screwing a lot of farmers and landowners out of their property,
If you want a real look at the drama of the water wars in the west check out "Cadillac Desert: The American West and Its Disappearing Water" - I think it's a little too biased against the US Bureau of Reclamation, but it's still a thorough and fascinating look at the politics and money of water in the southwest. Decisions made and policies set in the 20's and 30's due to people like Mulholland are still causing fallout today (and perpetuating stupid shit like growing Almonds in the desert - talk about wasting water!).
@@DocNo27 I was actually munching on some California Almonds when I read your comment. Now I feel guilty.
@Joe Milosch 8 Gallons? (Looks at can.) Jesus!
@@OLD_CROW It's because a bunch of rich people live there, when they all move to texas you'll likely see the death of those industries.
@@DocNo27 Cadillac Desert is a good watch (can be found on RUclips) and I agree with your take on the biased view. On the almond side, much of the Owens valley was self-sufficient farming land until LA diverted the water from the region thus some of the farmers moved to where the water ended up.
As a former resident (1960!) of LA, I lived downstream of another dam disaster, the collapse of the Baldwin dam in 1964. This was an interesting disaster caused by a geologic fault, subsidence by the extraction of oil, and a very dubious method of sealing the floor of the reservoir with asphalt. While the total destruction was less than St Francis, a business district and quite a number of homes were washed away. Great video!
When the Baldin Hills dam collapsed, I was amazed that you could have a dam break and a flood right in the middle of the big city.
I lived in Hawthorne when Baldwin Hills dam went. Watched it on the news.
This channel covered the Baldwin hills dam flood! I grew up outside of LA and can’t imagine a catastrophic failure on this scale, wiping out dense neighborhoods…
@@FeechLaMannas Yes, it did so very well.
You took an uncharacteristic but welcome and appropriately serious tone when discussing this. Highly appreciated.
I live a few minutes away from this dam. This is the best documentary that I've seen on the dam. You are very thorough. I will add one bit of information that I saw from another documentary. Mullholland had instructed that the dam would be built with a higher quality of concrete than what was actually used, which adds another component of potential failure into the mix. The density of the concrete used was found in later testing not to be up to the specs laid out by Mullholland. That being said, I think that even if all of the failures of this dam were removed during construction that it would only be a matter of time before the dam broke anyways. The canyon that the dam was built in goes back for miles and about every 6 years or so we get some serious flooding. I'm not an engineer, but I can't imagine that it would have held up under one of these floods that would have backed up a massive amount of water volume up the canyon.
Thank you!
@@PlainlyDifficult gonna add to this and say I've taken the official tour of this dam twice with the Santa Clarita Historical Society, and this video was more informative then their annual tour
In order to save money for cement preparation, the actual sand found in the bottom of the site was mixed with lime and used in the actual dam. Part of the problem, too, was the base of the dam intersected an ancient geological landslide. Directly beneath the dam was very hard conglomerate. Unfortunately, conglomerate becomes lose and muddy when mixed with water and its density flows through your fingers. What was not mentioned was that the Dam Keeper's son was also lost that night. Bodies of either were never found and presumably washed out to sea.
@@765kvline Thanks for the extra info. I enjoy learning more and more about this incident as the years go by and a drive by the few chunks of concrete that still exist on my way into town.
I was 9 years old, but I lived through the Teton Dam disaster and remember it vividly to this day. This story has always been a horrifying fascination to me.
Good morning from morning land!
Look up the Johnstown Flood. A dam broke because idiots were idiots and people died. I grew up about 25 miles from the site and we learned about it in school... Apparently it was one of the worst disasters involving human error and dams. But this one in the video DEFINITELY seems way worse... Eitherway, Johnstown Flood would make for a great video
Thanks for the suggestion
@@BrainScramblies Oh man, seriously? :P :D

@@PlainlyDifficult may we please get playlists based on the patented Plainly Difficult Disaster Scale?
Yes, this killed over 2,000 people and the cause was just plain negligence by a hunting and fishing club for millionaires (basically a modern day country club for the extremely wealthy). They ignored warning signs, altered the dam cheaply to save money when trouble started showing, and this one should be a 9 or 10 on the patented Plainly Difficult disaster scale.
"self-taught engineer" - Red flag!! I am an engineer myself and I've met some really good people already who are mostly self-taught. Physicists as software engineers for example. However, despite their superior experience compared to my (back then) Junior engineer experience, I noticed every once in a while that these people are lacking some theoretical background. I really loved working with these guys, because I could learn from their experience. However, the sometimes missing theoretical background stays - and that's something that might be acceptable for a software engineer, but not so much for a civil engineer... And improvising on a dam project also is the next big red flag...
my grandfather was a coal miner who decided to become a self-taught electrician and carpenter, we've had trained electricians and construction people come into the house and have to step outside for a few minutes to recompose themselves at the eldrich horror of somehow functional how-the-hell-is-this-house-still-standing-and-not-on-fire level techniques he used to piece things back together on his own. sometimes self taught is a good thing i've worked with a lot of excellent self-taught artisans and craftspeople at the gallery and shows over the years, but sometimes that missing professional knowledge of things like WHY aluminum wire should not be patched directly into ancient knob-and-tube wiring and be held together with electrical tape and prayers can be kinda important in the big stuff.
self-taught piano player, sure why not. self-taught dam engineer, noooope!
Like everything, it depends. I'm an engineer of 30 years experience and honestly the most competent engineer I ever worked with was self taught, but he is no ordinary man, being also an accomplished writer and entrepreneur, and an expert in the arts as well as the sciences. On the other end of the scale, you won't have to go far to find qualified yet incompetent people. The real problem is that there were no checks and limits in place to verify that this design was good. No single person's incompetence should ever be able to initiate a disaster, if it can then the system is broken.
I'm an industrial engineer, but I only went to university after working as a machinist for a couple of years. I don't know if it's the same in civil engineering, but as a machinist we would get drawings of stuff that couldn't be made, designs of mechanisms that we knew couldn't possible work. Engineers were certainly not well respected. Once I was in university I understood why. Most of them they came from an entirely theoretical education, had never really worked on any machines, did barely know what a lathe or milling machine was. When they did system analysis their calculations where entirely theoretical. They could calculate PID values, but couldn't tune a servo system in reality.
And most of them got their degree while being incompetent beyond believe.
@@slome815 Well, it's not their job to actually build or maintain it. However, there is something like "Design for manufacturability" or "Design for maintainability", etc. ("Design for X" if you want everything). And that is still not taught at every university and also the extend in which it is taught is often still not sufficient. But as I said: It's not the job of an engineer to actually build that stuff. However, an engineer who develops products should always take into account that this needs to be manufactured later by someone. If you break your fingers during assembly of the prototype, it is certainly not ready for series production... I know that engineers are often not well regarded, because they can't assemble or maintain the thing that they constructed, but mechanics often don't see that mechanics are also no gods. If mechanics could do the job of an engineer, we wouldn't need to have engineers study for 3 or 5 years at an university. A mechanic can for sure design simple things, but for sure he can't design a car that meets modern safety and efficiency standards while keeping the material costs as low as possible. People just need to understand what their job is and what they can't do, but other people can. Only then can a team work efficiently - when everybody values the skills of other team members...
@@fr89k Frankly, the last 2 years of my master's degree were nearly useless. I learned a lot more usefull things about designing, strenght calculations, PID, fluid mechanics in my professional bachelor years then I ever did when I went for my masters degree . The problem is not that many engineers can't maintain or build their designs, that's a given. The problem is that many engineers can't properly design a product. We had to make constant calls about dumb designs. (do we really need that 10µm tolerance on that handwheel?, Does that 15cm deep wheight saving pocket really need a 0.5mm corner on all sides.) The answer was usually, "oh I didn't think it mattered."
And about safety. If you ever have been involved in a risk analysis to get a product CE rated you know how much of a joke it really is.
After a couple of years working as an engineer I was so tired and dissapointed by the endless meetings about minor design changes and the lack of common sense of my bosses, that I quit and went to work a a CAD and machine shop teacher. A lot less pay, but at least I sometimes get the feeling I'm actually getting something done.
Self thought engineers can be just as good.
In fact some of the best engineers were self thought: James Watt, Tesla, Edison, Henry Ford and the Wright brothers were all self thought.
I live about 12 miles away from the disaster site (in Valencia, CA) and always take people for a hike that visit me in that area and tell them the story. This is the best video documentary I’ve seen on this disaster. I love your videos in general!! Thanks :)
What part? I live in Newhall id like to check it out
"During the inquest he (Mulholland) accepted all responsibility..."
A man of honor, unlike some we have known lately.
I mean, it was admirable in this situation, but go read about him. Mulholland was a sophisticated politician and essentially destroyed the Owens Valley economy over water rights. A complicated figure at best.
Yes very admirable
@@OnlyTakk I know well if him. He was despicable in many ways. Anyone driving down 395 can tour the area he exploited. Without him LA as we know it might not exist. None the less, the buck stopped with him. That makes him honorable in my book even if his values were different than mine. That is why T**** can never be considered as having been honorable.
@@archstanton_live What I find impressive in him was his ability, as a self-taught, self-made man to do all of these things-impressive, great, and terrible all mixed.
@@OnlyTakk That also.
I have read this story many times and I strangely always come away with an appreciation and respect for Mulholland. The way he accepted full responsibility instead of blaming those in charge of the construction is refreshing. I can only imagine that a similar incident nowadays would result in an endless circle of finger pointing. I also respect the fact that he was self taught and was so prolific in his career. I think his life should be celebrated in the civil engineering community instead of this one disaster defining him. Without Mulholland the city of Los Angeles may never have grown to be one of the largest residential areas in the country.
Agreed! He had the guts to shoulder the blame.
From the last slide in Dr. Roger's Presentation: "REQUIEM FOR MULHOLLAND
"
• Like any person, Bill Mulholland
had weak points in his character.
• His thirst for thriftiness was one of
these flaws, but that same trait
allowed Los Angeles to build its
municipal infrastructure AHEAD of
its burgeoning population, at rock
bottom prices
• He had an enormous capacity for
innovation; getting difficult projects
completed on-time and on-budget.
• Engineers of that era tended to
underestimate the complexities of
pore pressure response, especially,
on concrete dams
• He had the depth of character to
accept responsibility for
shortcomings in the dam’s design
and construction which very few
people at the time fully
comprehended :
To boot, From all I have read about the issue, is that Mulholland did not get an Engineering degree. His degree was for another engineering specialty. But because he was already Chief of Works, the oversight was not noted. He was a very Big Shot before the catastrophe.
Mulholland was a man of a long-ago generation.
Im so early, the flood wave haven't even swept away my house yet.
Also, theres so many dams out there just waiting to become a plainly difficult video
I really appreciate that you say the number on the plainly difficult disaster scale in this video, it's a small change but it means a lot to me
Been waiting for this one !!
The wait is over
The absolutely most shocking discovery of this video is that you CAN have a man-made disaster without a man in a white lab coat holding a clipboard.
Its the suits you have to look out for
As a man in a white lab coat holding a clipboard, I support this takeaway. We just run the numbers and speak the facts - it's not our fault if the idiots in the C-suite choose to ignore our advice and think that the laws of physics care about their wanting to save money!
This disaster was also covered in depth by Ask a Mortician on RUclips and the two of you are literally the only people I’ve heard talk about it. Seems odd it’s not more well known!
I see my recommended is spot on💀😂
Tom Scott did a vid about this years ago as well
I've seen a few. It was an actual TV documentary that brought my attention too this incident though, and it was the thing that was on my mind as the dam above my town was having issues.
I must have seen over a half-dozen docs on this disaster. It was Mulholland, after all.
They even went over this disaster in Ken Burn's "The West". It's a very well known event.
There was a PBS documentary on dams in 1997 that covered this. Included was some rather gruesome footage of recovery efforts.
Thank you for pronouncing “butte”” correctly! I listened to another narrator talk about the “”Elephant butt dam””, while laughinng mine off 😂!
There should be a Butt Butte somewhere.
Anybody who ever lived would tell you that Butt was the correct pronunciation, as it was the ass end of nowhere.
Elephant "Butte" is right next to a town called "Truth or Consequences" (they voted to name it after a TV show). Also home to the Toy-Box killer 🤯😱
I always pronounce it "booty". Funnier that way :D
Heh heh. Damn elephant butt.
The moment I heard "self-taught", I knew what kinda failure this would be. Not that that's innately a red flag, just that it's the sort of thing one only brings up ominously
A self-taught engineer would never fly today. Even comparatively simple things like culvert design would require a degree. This could have only happed in 1920s America.
@@NetAnon that's because at the start of his career the US was still recovering from the civil war and there were no universities that specialized in engineering or geology. I find it inspiring that he learned from trial and error.
It's also worth considering the state of the field at the time. What an "engineer" needed to know in the 1910's and 20's was a long way from the amount there is to learn today. I agree that you shouldn't let a "self-taught" anyone direct a major public project, but some of the things we teach as textbook engineering failures today hadn't happened yet when this was built.
@Acme Inc. American Healthcare is over priced and the treatment side is underfunded. Most of the cost discrepancy between American and other nations healthcare is in administration, middlemen for insurance, and inflated drug prices.
I hope for a socialized healthcare system in the next 20 years as that would indeed lower costs of administration and healthcare in general, it would also point to improvement towards the overall political climate and a willingness to pass more progressive policies.

I was expecting the distracted boyfriend meme when you said Mulholland was distracted by a Colorado river aqueduct.
My dad and I hiked there around 2000, during a period when nobody cared about it anymore. At that time the road through the canyon went right through the former dam itself. Today, the road has been moved westward and under the west wing of the former dam. It’s an amazing place to explore and visualize where the dam was and the destruction left behind.
Incredible to read all of this admiration for Mulholland. I’m not sure what my favourite Mulholland moment was; draining Owens Valley creating a carcinogenic dust bowl that will continue to blight the entire west coast of the US, or ensuring that vital farmland in the north of california is imperilled due to water exporting. Come the fuck on.
Notice how people always get fkn ego boner when they read about exploitation and theft of the humble many for the benefit of more powerful few.... Jfc
He had drive, ambition and determination. He became a self-taught engineer. And when he accidentally caused a massive disaster, he admitted responsibility and retired. At which point he was already in his 70’s. He was a man of great character. That’s why people admire him. I know nothing about his personal flaws or the massive damage his polices have caused. Both of which I am sure are long lists.
@@Erakius323 Admitted fault and retired... at the end of his life when he had nothing to loose. Not very impressive. Admitting fault is the bare minimum one should do. It's not praise worthy.
@@dzhang4459 When was the last time a politician admitted fault? You think Pelosi will ever admit fault for her insider trading?
@@Erakius323 the city of LA hired him to steal water and that’s what he did. They wanted a self taught engineer because a real one would’ve told them no.
Him taking full responsibility is impressive, can anyone imagine that today?
I would, and many of my (former) colleagues. But someone in such a politically charged position? No.
Mulholland caused every one of those deaths through his arrogance and corner-cutting; he was warned, he was told when the failure began, and still he did nothing.
Negligent mass homicide.
Depraved indifference.
He gets no respect from me.

I absolutely love your videos, which is why I want to provide a bit of criticism: I feel like it would be helpful to include 3 types of maps when you say "which is about here on a map": Show where the country is, show where the region is, and show the local area. In a lot of videos but especially this one it's really hard to tell what the map is showing or to get a concept of what it's near. In archaeological contexts we use multiple maps so I thought it would be prudent to suggest. Love your content as always, cannot wait to continue learning with your next video.
I read "Man Made Disaster" in 1964 in junior high school and arranged to have my brother drive us up to the dam site. It has changed a good bit over the past 57 years. First, we drove up the old road, and it was clear where the dam was because the terrain to the north of the site was lush, green and wooded. The area below was still scoured and nearly barren. Of course, it had only been 36 years since the disaster. The wing wall was intact, and the steps of the "tombstone" were more visible. We brought back a chunk of concrete from one of the downstream sections. We had also talked our way into Powerplant # 2 during our 1964 trip. We saw the transformer that was wrenched out of the basement and tossed down the canyon, fished out, welded back together and re-used.
I went back in the late 1980s. I hooked up with a Boy Scout troop and their scoutmasters, one who had a copy of the book. It was interesting to be among young men who were my age when I first saw the dam. It was clear that the wing wall had been demolished with explosives, not natural weathering. We went together to San Francisquito Powerplant # 1 and had a fascinating tour. The Pelton Wheel generators still had their "50 Hz buckets", designed to generate 50-cycle power that ran Los Angeles until the early 1950s.
I have visited the ruins of the South Fork Dam above Johnstown, PA, and, at the end of the summer, I am going on a military history tour in Belgium and France, then flying to Italy to see the Vajont Dam, the site of the October, 1963 landslide that sent a 750' tsunami down a narrower canyon, killing over 3,000 people. I have long been haunted about the St. Francis Dam. I will return sometime, in the next few years,

Mulholland's famous quote about the disaster: "Whether it is good or bad, don't blame anyone else, you just fasten it on me. If there was an error in human judgment, I was the human, I won't try to fasten it on anyone else."
I like you back ground music. And your microphone is alot better now. Keep up the good work and I enjoy your content and videos.
Will you cover the Johnstown Dam failure and the destruction of Johnstown?
I'm really enjoying your videos. Informative, and entertaining, while being short and to the point! I subbed!
I first had an inkling of this disaster many years when we visited a cemetery in the Santa Paula area. We started to realize the abnormally large number of burials in March 1928. There were many families with the same date of death. I later heard of this disaster from a friend. Such a sad situation.
I really enjoy your dam videos. I worked at a hydro electric power station and part of my job was inspection of the dam twice a week which was much larger than this one, it was built in the 70s before computer simulation so they built a large scale model of the entire dam and catchment, filled it with water etc. There were two cracks in the dam, both about 2/3 of the way up on each side on the side not facing the water, they didn't leak and there was no concern about them as the scale model did exactly the same thing and it was expected to happen, amazing engineering for the time.
an "acre-foot" has to be the single most stupid unit of volume that has ever existed.
It kinda makes sense though, you partition a volume with a large surface area that varies with elevation into smaller 'slices' sort of like a Riemann sum. It's dumb, but also seems to be pretty practical and intuitive.
@@HendrikTheThird and easily manipulated. Measure the volume of a salad bowl, then a bread tray, if they have the same surface area the volume will vary thus the weight will vary considerably. The difference between 3 000 000 m3 and 4 000 000 m3 is a a million tonnes. An important calculation I suggest. Bernard appears in the dictionary but no description of his feats.
Yeah get with the metric system people..

Great video and well covered as always. Love the audio on this video too-new mic?
Great content as usual but a note about the vocalization itself. I much prefer this style than the ‘uptalking’ vocal fry way that others have been read. It’s almost like you took it down a notch and it comes off SO much better. So very much better. Please do them all like this, this was easy to listen to and understand despite being a very disturbing story. Just on a technical level, this was really good.
How have I only just noticed the little black and white bar before the breaks? That’s a right blast from the past. 🙂
Welcome to itv of the 90s
American networks back then had a short tone before local ad breaks. It sounded like a touch-tone phone.
My great-grandfather was working for Edison in the camp below the dam that day. The dam failed due to multiple factors according to some more recent reports. One of the sides of the valley the dam was built on was the location of an ancient fault line that was only discovered due to more modern technology. The engineering knowledge at the time was not advanced enough to fully account for all factors of construction like concrete contraction and hydrostatic pressure. Mulholland also did not just quietly retire, when he first heard of the dam collapsing he was absolutely crushed. He never forgave himself for the damage he caused. He died after living for years with the crushing regret of what had happened. He was a brilliant visionary who helped Los Angeles develop to what it is today, but circumstance and the prestige he earned as a prominent figure placed him in a situation that was beyond his skills without realizing it. What ultimately happened robbed my father and his siblings of a grandfather long before they were born, but it would be unfair to lay the blame entirely on him.
This is my Community... I am glad you covered this!
Hope you enjoyed it!
So glad you did this! Fascinating story that I’ve studied quite a bit as I moved into the area the flood.
What I’ve learnt about dams from this channel is that overly engineered is always better, even if it costs more
I didnt know about this until I saw Caitlin Doughty's video "The Massive LA Disaster You've Never Heard Of" and honestly I never heard of this incident at all. it seems like an incident that seconds from disaster would have covered
My favorite example of a great dam in the wrong place is Vajont Dam. I would love to visit it and try out my Italian there. Such a tragedy on so many levels. What an incredibly well built dam it was! However, it is nearly inconceivable to me that so many warning signs had been ignored and construction proceeded anyway. The death and destruction was horrendous--just as St. Francis, Teton, Johnstown and other calamities. Engineering hubris in the face of the obvious is a major factor in bridge, dam and building catastrophes.
I like this calmer tone of commentary
Quite soothing to listen to
“Exacerbated” is a fun word to say. You have all the sounds. With a little practice, you could teach your brain not to default to the easier “exaggerated.” Although both fit, disasters are always exacerbated by something, and Plainly, no exaggeration is needed to display the horror of the St. Francis dam failure.
Just make sure not to get it confused with the word "exasperated", which some do!
Your comment is funny because you're trying to correct him for not saying exacerbated correctly, but then you mix up exaggerated with exasperated. :)
Those aren't synonyms...
@@casbyness I was referring to how some of my co-workers write it "exasperated the issue at ____" when they should be using "exacerbated".
That's a darn curious choice of hill upon which to plant the flag of pedantry when the narration on this video contains several actual crimes against the English language, such as "analysis-es", "monumentous", and "Mulholland raised through the ranks" :)
Always interesting. Keep up the good work fella and stay safe.
Locally this was known as San Francisquito Dam, even though the formal name was St. Francis. I grew up near there.
Thanks for an excellent story. 😉
Spencer dam in nebraska when.
I drove through the area after the failure, and man it was something else.
Yes the old Spencer Dam was hit hard by flooding. I remember it well.
I remember requesting this topic back when I first found your channel. An interesting watch, as always.
So what's a 1 on the disaster scale? Spilled milk?
Yeah; there's no use crying until you get up to at least 2.
Broken pencil lead.
I live about 40-50 miles from the area, fascinating the things you learn about where you live sometimes.
Caitlin Doughty did a good video on this as well. Combining Plainly Difficult's video and hers, you get a really indepth understanding of what happened here and how it affected people then and even now.
i love getting up saturday morning and see a new upload!
There's a lot of interesting stuff about Mulholland (and the general fuckery surrounding L.A. water) in the book Cadillac Desert
Yes - it's more than a little biased in it's hatred of the US Bureau of Reclamation, but it's still a detailed and fascinating account - a book that anyone who lives in the American Southwest should absolutely read.
@@DocNo27 the reason for the percieved bias is that reclamation has failed in all its projects to paybfor themselves by genetating electricity and charging money for the water... Never recoverd the cost of any project... Though all the proposals submitted claimed they would pay for themselves..

Thanks for such a well researched video Plainly Difficult.
You’re voiceover work is great in this video 👍🏻 great work 🍻
Hmmm. I wonder if I haven’t heard as much about this one before because Mr. Mullholland took responsibility. Normally companies and people try to pass the blame.
Nice work as always! Loved the background music on this one.
"Self taught engineer"
WELL I WONDER HOW THINGS COULD GO WRONG...
Well, we got our knowledge from somewhere. You can't go to school for things no one's done before...
Great video! You mentioned the uplift failure but didn't mention why the center section did not fail...
Uplift was a very new and theoretical concept at the time and mathematically showed that concrete dams could not use the same weight-to-vertical ratios as earthen dams because mud slurry is more dense than concrete. Earthen dams don't suffer from uplift failure since they are not a single unit structure like concrete dams are. Not to mention the (water-soluble) limestone veins, reported in the geological surveys at the foundation that were ignored.
The St Francis damn was built with a somewhat new, uplift-relief design of vertical columns built within the center section. Unfortunately this design concept came to be after the abutments (left and right side) of the damn were already complete. The center section (the tombstone) DID have uplift-relief columns installed and did not become buoyant which is why it survived while the previously constructed abutments (without uplift-relief columns) did not.
Self taught engineer, overseeing massive civil projects
Guess he incrementally completed larger and larger projects n they just figured he hasn't killed anyone yet....must be fine 👍
Right...you should look him up its a fun read. He's self taught but he's quite the brilliant person. A human error is a human error no matter what degree you have or how long you studied. Just look at Malpasset dam. I'm not excusing his action that leads to the death of hundreds, but don't discredit the man of his achievements and capabilities.
There have been highly professional engineers who didn't ignore the rules of mechanical stress but simply forgot the lessons in their attempts to trade appearance for structural integrity. Leon Moisseiff was a "professional," not self-taught, and had many successful bridges under his belt until the Tacoma Narrows 1940 Bridge took him down.
I much approve of the style of narration in this video, compared to others by Mr. Plainly Difficult. :)
"ac. ft" Nah I swear freedom land just making up means of measurement now 😂 Informative video as always I've actually never heard of that one 😶
Acres of surface by depth of area
Acre-feet is a real thing in hydro engineering. It is a volume of water that covers a one-acre area to a depth of one foot. It's about 1/3 of a million gallons.
Unbelievable. I'm 49 and know my imperial units fairly well but it was a new one on me. Just when you think the non-metric system can't get any sillier. I'm surprised they didn't use bushels.
YAY! My Favorite man made disaster. I first heard of this from the book and PBS movie "Cadillac Desert", which is about how the Owens Valley, once the jewel of agriculture in California, was robbed of its water by William Mulholland and pals. I was then fortunate enough to live in the LA area around the turn of the century, and got to 4x4 through the area of the dams remains on several occasions. You can actually drive right through the where the dam was on San Fransiquito Canyon road. Its a bit hard to tell where things were at first, but you can still see the foundation of the dam there and there used to be giant chunks of the dam around the area. There was also a tall tale about how, at the moment the dam failed, there was a van full of gold driving across it carrying the pay for the army or something, and it was never found. While I mourn the senseless loss of life, I'm still fascinated by this engineering disaster. I also watched another documentary about the dam, which concluded that there was a rift in the embankment from a long ago earthquake, that they could not have known about then, as they didn't have ground piercing radar back then, and it was most likely the cause of the landslide and subsequent failure of the dam. Wish I could remember where I saw that. Great work as always!
The guy in charge acknowledged responsibility and resigned. Such things do not happen nowadays.
Yeah, that totally brought back all the innocent killed and the land stolen.
It's worth noting: the area chosen was totally unsuitable for a dam. the lower portion of the western side of the abutment was composted of mica and schist, with talc mixed in. this ran all the way up the eastern hillside. basically, the whole place was a sieve, and the dam behaved like it. it was in a vice, being squeezed by hydrostatic uplift from the bottom and the eastern side. in some ways it s a miracle that it lasted that long.
Someone watches that nice mortician lady videos. Let's see how it compares.
Every year, on the anniversary of the dam’s failure, groups of people visit the site and sit in silence at the exact time of the failure. Kind of haunting. Traveling up the canyon, you can see the destructive remnants. Parts of the canyon are steep and narrow, meaning many had no chance of escaping a wall of water over 100 feet high.
PD: *Makes video about a dam.*
