Lived in a company town where they diverted a river... flood cycles every five or seven years would have the river breach and carry on its original course no matter what the company did. Good luck to the residents of San Clemente.
Average annual rainfall in that part of California is 10.5 inches/26.67 cm, not much risk of a flood except for the dam was to fail then there would be a flood of water and sediment flow landsliding into the homes down the ways. They could have built a miles long slurry pipe to dredge the built up sediment down river and past most the homes and let the river take the course on its own with the rest. Now if there was the rare chance it was to endure a flood then those bends they made for the diversion would rear their ugly backside on these foolish 'experts'.
Depends on how much money is spent on diverting the river. Trust me they could divert the river and it wouldn't come back to it's original channel IF they do a good enough job moving it.
I add my voice to yours. My prediction is that no matter what is done, Mother Nature, who is a bitch, is going to arrange things as she sees fit. May as well let her handle if from the get-go.
One would think that upon the construction of a dam, they have a need of an outlet at the bottom of the dam, to purge the silt n’ such to avoid, or slow, the filling of the reservoir.
Most dam removals are half the heights or less or in a area along the river where doing a diversion flow is prohibitive, due to terrain or property ownership.
@@Joshua79C the owner of Tesla has the boring project and is doing feasibility from Baltimore I believe to wash d c. This is 50% less cost. Most dam projects had diversion tunnels to divert a river while the dam was built. The dam projects are usually navigation streams that require a renewable 50 year license. The public and private power only want the benefit not the liability. The paradise for is $9 billion liability because the power company was liable for the fire because they did not trim trees. Forcing bankrupt. The same with big tabbaco causing lung hospital bills liability.

Design development operation and decommissioning and liability cost. Then gross income minus cost and liability = net income. By 2020 we will have pnw dam cost. Btw WA state only has limited sovereign immunity. The only state that takes liability...
Several comments have been made regarding the engineering choice of how to deal with the dam sediment, the most daunting and costly part of the process. Dam Decommissioning is a relatively new engineering procedure ( with Nuclear Power Plants Decommissioning soon to be next ). There is a slowly growing body of knowledge on dam decommissioning, and what works under what condition. While it is true that experiences of the 34 million cubic yards of sediment of the Glines Canyon and Elwha Dams ( Washington State USA ) showed that, instead of a full rapid release, a controlled draw down worked to move the sediment with little effect upon the environment, in this case ( and others ) there were little to no "dense development" ( County, City and Private land owners ) downstream. So with the San Clemente Dam, even a controlled sediment release could or would have significant effects upon riverbanks, golf courses, conservation areas, boat docks, parks, roadway overpasses, etc. An uncontrolled or controlled release of sediment at its core represented a significant potential liability / legal costs that would have been unacceptable to any stakeholder in a project of this scale.
Man, y'all really overthought that whole sediment issue...if you had just removed the dam and let the river cut its natural channel only the sediment that would be in the footprint of the river would have been washed away...all the remaining sediment would just simply become the banks of the river. Only a small fraction of the 2.5 million cubic yards of sediment would've washed downstream.
This country is being invaded by people and companies that are only interested in paychecks,pensions and benefits. Governments dictate these policies and the companies move in to finish us off. The real problems are being overlooked because they appear to difficult to solve.
+hello hun Sorry. Is this a positive or negative comment on the project. Excuse me if I'm wrong but judging by your comment, it sounds like you think there are teams of demolition companies just walking around your country looking for dams to demolish and make a bit of cash from local or national governments at the expense of the tax-payer? The "real problem" is an unsafe dam that could potentially wipe out homes. The difficult solution was overcome by careful planning and execution. Job done. I have been veiwing some other videos on YT about dam removal around the world and it appears that the USA is the world leader in this field and forgive me if I'm wrong, but a disused dam serves no purpose and eventually becomes a hideous eyesore which , in this case, could endanger lives. Therefore, the government (thinking about its people and the environment for a change) makes plans to rectify the problem. Thus, you demolish it. I guess if magicians were actually able to perform useful tricks, they could have been employed to just make the dam vanish and instantly restore the local area to its former glory. However, magicians cannot do that and years of planning, preparation, heavy machinery and labour (labor) is used instead. Err! That requires people to be paid and often (if only temporarily) injects a bit of much needed cash into the local economy. I suppose you could employ prisoners to do the job by hand for nothing and then it won't cost a penny (dime) but then you probably wouldn't want to leave your home as the place will be teeming with undesirables. I cannot see any negative aspect of this at all apart from the heavy machinery disturbing the area for a year or two. Which you cannot avoid. Please explain your comment in detail.
The robber barons said the same thing. The rail roads set freight rates that bankrupted groups of people and communities. In 1890's . teddy Roosevelt cleaned it up. Still caused recession and ww2. England controlled 40% world power now they are third world. That leaving brexit will bankrupt them. The bond and festivities casino is next ready for a reset. Congress and WH will change in 2020. The new deal will create new technology and energy trade and health care will reform. Africa and so America will become our breadbasket.
@@HyperBiker you seem to forget Corp wish to extend cost to all and benefit thru Corp welfare. Tracking is wasting a lot of French water with no guarantee we will not polite water for 100 years or require expensive reverse osmosis and world wars or hurricanes and fires. Five years drought in CA may become permanent.
The entire area is about to run out of water. So glad they destroyed their reservoir... But please go on worry about the fish that are already dead because the river is to shallow to sustain them and there is now no lake for them to survive the drought in. You tree hugger types are fools.
@@CH-pv2rz As mentioned in the video, 90% of the reservoir was full of sediment, so its water holding capabilities were almost non-existent. Does it take a tree hugger to explain the facts to you?
+Chris Rugar When you have large amounts of silt to deal with then its a good idea to have a good plan of action. Apart from the unbelievable stench that comes from exposed silt you also have the problem of oxygen removal when it gets disturbed. The stuff should be treated like toxic waste.
+Chris Rugar So what would your solution be, my friend? Just leave it until it collapses? Blow it up with heavy artillery? What makes you so angry about this project? It sounded as well thought out as it possibly could be. I don't understand your anguish. Sorry.
There have been enough studies on enough dam removals to show that rivers have a way of removing sediment on their own. A progressive removal of the dam allowing time for the sediment to be slowly released down street. But no. Let's spend millions of dollars on studies from every department that can get their hands on it to find out the same thing that every other study has found. A progressive release of sediment will have no impact on down steam wildlife.
Typical. Owner wants magic to happen overnight but probably couldn't even change the oil in an excavator so... I'm so tired of working for other people. 18 year electrician and Ive just decided I've had enough of hearing the word "Owner". I honestly don't care anymore.
Well that's nice was hoping to see dam remove but no I just saw the cost of a lot of time and money the stuff behind the dam should be allowed to go down stream and build up the delta that is no longer there.just go to dam remove washington state and see the river restored on the Olympic peninsula and the new economy system the delta has done there.enough said
All that stuff would normally flow downstream a little at a time. You cannot remove the dam seen it all at once. Disaster...to the people that live below.
What a huge loss to the environmentally concerned. It will take an act of God to re-approve a dam construction over there again. Without these dams we'll be like a third a world country that doesn't have this infrastructure, suffering through catastrophic floods, famine, and have to resort to quick and dirty fossil fuel generators. Ecosystems are always adapting, some disappear and others emerge. It's one of many natural processes that civilization can intelligently be stewards of.
There was no electric generation on this dam. Silting made it virtually useless for flood control or water supply. All man-made objects have a useful life span. This one has served its purpose and now must be removed.
no video of it actually being removed 😞
Just take out a little bit at a time the river will take care of it self
