Thanks Juan! The company i work for in Alaska bought two of those ex Conco concrete boom pumps, i removed the lettering but kept the same colors. Its called Greatland Concrete Pumping. Those pumps there are very big, some of the largest made, i saw them being built at the Schwing factory in Minnesota back in feb while getting my certifications.
At the Oroville public meeting, one of the engineers said that 5,200,000 acre feet of water was released during the emergency spill situation, this would figure to be enough water to last the city of L.A. for ten years. At the going price of water in L.A. city this would amount to $16,000,000,000 dollars of water. So the next time someone complains about wasting water during the dry season, look towards Sacramento and all the misplaced money wasted.
I'm extremely impressed by the amount of progress that has occurred since the failure and by the engineering concepts and designs being used. They are doing a terrific job!
Awesome job Juan. Re-covered / updated a lot of the details of this most interesting CA story in recent memory. Your pioneering online coverage sets the pace for the future. Nice to see so many fans appreciative of your work. Please continue to update this story, along with your other excellent videos, Pete! Hope to hear from you again real soon...
That new road down to the gates on the lake side is probably the access road. They have two of the spillway gates open for dump trucks and other stuff to go through.
Nice toys!!! Thanks for the great video. One of the "informed" guys on the chat room said the structural slabs will be 36" to 40" thick. "Expansion Joints" are a interesting question. In some of the DWR photos, you can see that the rebar comes out past the forms to couple with the rebar at the next section. Maybe the E-joints will be every other, or greater, spacing. That "secant" style wall is the same way you "stitch" a crack in a cast iron (engine block for example) piece. After your latest tour, they have started standing up some "wall" rebar at the USW. Interesting how the structural slab sections definitely look "rectangular" when seen from the web cams and definitely are close to square in reality @ 30' X 37'. Your overview an other still photos show a more accurate almost square shape. Interesting how camera angles and distance affects images.
Another OUTSTANDING presentation. Thanks Juan. - And loved your final approach and landing sequence (plus the flag). Greetings from Catskill Mountains, NY state.
Loved that musical accompaniment to the DWR's little video. Just a bit over the top. :) From a photo that they posted in their gallery, apparently the road coming up the spillway inlet is being used to deliver materials through the gates to the staging area on the upper spillway.
So grateful for awesome updates and reports! Who would have believed a "little" hole in the spillway in Feb. would turn into such a HUGE project. It's all to save lives, and water. I'm also amazed that they can keep that RCC so cool in such hot temps.. over 100 If think.. Thanks again Juan for an amazing job!
Great job again, Juan! I've followed your Oroville reports from the beginning. Your presentations are factual, contain much more detail than the lame stream media, and are unbiased. Excellent work.
I'm a structural surveyor (simple pen, clipboard, high vis vest and hardhat man) in the UK and frequently assess the level of air and water-borne contaminants in concrete and older masonry dams. The size of the Oroville Dam is staggering in comparison to even some of our biggest dams - Ladybower in Derbyshire being one. The diffusion blocks at Oroville are as big as houses but ours on some of the Longdendale dams near Manchester are small enough, if they were loose, to be picked up by hand. Amazing.
If they get a tiny hole in the epoxy coating of the rebar, an electrolytic reaction can take place, creating what is known as a holiday. This can completely compromise the rebar in short order. But it's much less expensive than adding chromium to the steel recipe. The new Oakland bay bridge uses chromium steel because of the saltwater.
BlankBrain - I agree... And I would add that the compressive strength of epoxy is negligible compared to that of steel and concrete. It is not hard for concrete grains to poke through epoxy and start the rust process. But I suppose it will slow down the rust a little.
The zinc is sacrificial, so the steel can last longer than it otherwise would. When the zinc is depleted, the rebar can rust. Galvanized rebar distributes the charge along the entire surface. Epoxy is an insulator, so when it is compromised in a small area, the entire charge concentrates at that point.
Beautiful flyover and annotations describing the scenes the viewers are seeing. I've done a little editing and video assembly to really appreciate your time and attention to details. All qualities that reflect positively on our professional pilots corp crisscrossing the skies every day. Well done.
Juan Browne for President!....... Just sayin'.... or perhaps a Peabody Award for Excellence in reporting! Damn, dude---er, DAM....You ROCK. Wonderful Family, Superb reporting, Intelligent, Accurate, Info., Funny goofs to keep it light, BEST Amateur reporting I have EVER seen!!! You, Sir are 1 Amazing American! Thank You is simply Not enough. God Bless You and your Family! You are performing an INVALUABLE, 1 of a kind service and WE the People send our Gratitude and LOVE!
Juan ... to add to your comment on waterflows this next rainy season into the old croyle canyon and dirt erosion into the diversion pool .... i had posed this question to Dave Guitierrez/DWR . He told me that 30 foot sidewalls would be installed (of RCC] on the RCC portion of the spillway for the 2017/18 rain season. To be reinforced with rebar and structural concrete next next year.
Thank you for all you do. Stay blessed and safe. Crews are appreciated. This should be no issue. The Money should be put into saving lives and paying the professionals. God Bless
Thank-you Juan, for another confidence building, non sensational factual video. Just as we like it! Love from Scotland. (shh, don't tell anyone, the sun is shining!)
Another timely update, Juan! Keep doin' what you do, when you're not otherwise camping and wandering backroads and vistas of the Sierra, Nevada, and OR .. oh, and earning a livelihood! ;-)
I'd really like to know who does the music for the DWR videos, and where we might obtain a copy/cd/mp3. They really should give a credit to them on their videos.
Juan, you haven't mentioned any wildfires in your area. I have read that NorCal has been getting their ass handed to them with fires everywhere. I know you guys had a big one about a month or so ago. Hope all is going safe up there..I'm from San Diego, and i loved your coverage of the fires, especially CDF Air Attack Div.
Top-notch reporting, Juan, thanks! The "Torpedo" derby soap box car is pretty cool (will check out that video also). And what's your take on recent news about a 2 ft crack and 4-inch offset that's developed in cement near Gate #8 of the head structure? Anything you've found out would be good to know. Thanks again & take good care! 🇺🇸 🤓👌👀
The new terminology is upper and lower plunge pool on the Disclosure Media chat board. The lower plunge pool is being brought up to grade at night with RCC. Excavation to bedrock is ongoing in the upper plunge pool which is the deeper of the two.
man, the cost for this is staggering, the sheer amount of various concrete, metal, coated metal they need not including all the labour, machines, special machine. Absolutely staggering.
I have seen elsewhere there is need of work on the spillway gates as well. Apparently there is a crack in the concrete structure.. it's being monitored but it seems to be expanding ever so slowly.
Yes I agree It's a dam fine video, but yes a dam tripod would be good☻ and maybe a dam zoom camera, love the dam luscombe footage also, This dam catastrophe has made you quite popular, as a dirt contractor myself, could you explain the dam RCC and how its made? we had a dam disaster here in 77 there's not enough dam concrete made to plug that hole, How much dam money is this going to cost, Kalifornia is going to have to implement a dam tax. Ok that's it for the dam questions and dam comments, dam fine job Juan
Another interesting video, I'm still watching these from Australia, I've no idea why :-). Also it seems so complicated to fix this I don't even understand how these things were built to start with back in the 50's or whenever. In Australia the Snowy Mountains Hydro scheme was built then, I bet they couldn't even afford to build that now.
Not far from the dam, at Butte College (where I used to teach) they have an annual Rattlesnake Day. It's not too uncommon to find a snake in a classroom, so I always did a visual check each morning (though never found one.) We have two types of rattlesnake in this area. The timber rattler which grows to about 5 foot, their bite is not necessarily deadly. There is a lot of swelling and discoloration as it starts the digestive process. The only way you would probably die from their bite is if bitten in the neck and the swelling blocks your air flow. The second type is the northern pacific rattlesnake, the deadliest rattlesnake of them all. They only grow to a little over 3 foot in length. Their bite causes little swelling or discoloration but instead goes to your brain and you "forget" to breath, so die of cardiac arrest. Not that you can't breath, just that your brain forgets to tell you to breath. When out hiking in a group it is often the third person in line that gets bitten; the first person wakes the snake up, the second person pisses the snake off, the third person gets bit.
You said you were using a phone. Surprisingly good image in the zoomed shots. A fairly basic monopod would do the trick and it can also be used as a selfie stick when needed. Good stuff. Someone buy Juan a Sony FDR-AX53 but maybe check if he likes that model before committing! Just like to put in some praise for the DWR video team, they are making some nice videos with good editing.
We've seen in past videos that he has a drone but I believe that area is a no fly zone for private drones. That would rid all of the shaking in the video plus better close-ups. A good DSLR and tripod would also help.
How long does it take for you to go from prop to jet and back with your mind/brain adj.? Thank you for the great videos And may god allways be your co-pilot..BRAVO - ZULU!
Good coverage, Juan. I liked the video of the repair attention the Emergency Spillway is getting. The reality of last season was the ES. Have you heard anything mentioned about the flood gates and the crack in the surrounding concrete? Thanks for the ride in the mighty Lyscome.
You made a comment on the expansion joints they will need. Got to be the one weak link. Would it make sense to place those joints over the land drain channels?
The drains have been incorporated into the foundation already and yes, they are directly beneath the joints. The joints leak by design. There must be small gaps in order to allow the slabs to flex. The joints are not a weak link. They are required and are thoroughly considered in the overall design.
Funny, you panned up talking about the dam and all I could think was 'wow, look at that thunder head peaking over the gates'. Sure enough, you addressed it. Cumulonimbus right? In a later shot it's anvilled out. Keep the Luscomb away.
So what I don't understand is why the roller compacted concrete does not need rebar for strength as poured concrete does. I think I ask about the compressive v expansive strengths.
The roller compacted concrete is used to build a foundation. This foundation will only experience compression, no pulling forces. Rebar is for pulling forces, concrete for compression forces.
Thanks for the reply but that doesn't quite answer the question. They don't use poured concrete without rebar where they use RCC. In other words, when I delved into it, I read that they can use RCC on simple driveways yet every poured driveway that I am aware of has a wire steel sheet in it or rebar. I don't want to beat this to death but there must be some fundamental difference in the two products.
Unless I'm mistaken, using it in driveways has a pulling force on it...that of driving up and back. Every seen a tarmac road after heavy trucks have driven on it? It get pushed out of shape. Rebar in driveways adds structural integrity to driving and parking heavy vehicles on it. Sure its compressive, but they don't always use RCC in driveways.
last426 The rebar is in a driveway because the lack of a quality base. Roman structures have no reenforces ( very little frost heaving in the warm climate) If you a drive over solid bedrock with no way for water to get under there would be no reason for bar. Rebar is often a cause of failure due to rust and different expansion rates
That spill way is never going to fail now. Compared to what was existing to what they are doing now it is like night and day. All the degraded "red rock" removed. Virgin gray rock now as the base. This should had been done in the original. Nice report Juan. Go treat yourself to a fun fire road.
Keep in mind that prior to this years Pineapple express lake level was far lower then 700' ft. What will happen if we get another pineapple express 2018? The power plant 30,000cfs will not be enough?
what! you mean the new spillway will be ready to accept that kind of volume before permanent completion? WOW1 then theres no problem.. did not know this fact... Thank you...
Mike Ovanes, the res level was never below 725ft in 2016. That said they passed more than the total volume of the reservoir through HPP+MSW+ESW during this last season so if they had another one like that, I'm sure they'd have to use the MSW. And yes their intention is to have up to 100K CFS capacity through the MSW for the 2017/2018 season, even if it means putting some of that water over bare RCC (to be covered with leveling and structural concrete next year).
Right around the 14:40 mark there is a reflection of water where the emergency spillway water went. That can't be left over from earlier this year. Do you know if its a active creek?
Juan, Do you have any info on the vegetation replanting plan once all this work is done? Are they thinking that far ahead yet? Control normal erosion on the face of the slope.
Juan you do awesome work. I am correct in that the majority of the dam and levee repair funding is coming from the country in which California is trying to secede from?
It's starting to take shape in a solid way, this is a relief to see. I believe they will get this all ready on time. It is very unfortunate and sad to hear that the funding did not come through... You'd think with all of the money generated from pot taxes in California that there would be no problem paying for it!😕
Apparently I missed the explanation of "unauthorized blasting" somewhere along the line. Can anyone point me to an explanation? Juan, as always, excellent coverage of the very interesting project.
Juan I'm tellen you. You and Pete should do a little beach combing with the lake at this low level. No telling what treasures you guys could find. You are very good at explanations and keeping this series interesting. Thanks.
cember01 I would like to, but it would require very special permission from the company, the union, and probably the FAA...though I see others have done so.
blancolirio Understandable. I've heard that drone footage that is in any way connected to revenue (like a monetised RUclips) is now being scrutinised by FAA, as it requires a license. You heard anything about that? Great reporting, great channel btw. :)
Do you know how they are preparing the aggregate for the roller compacted concrete? Are they washing the spoils? If so, how do they keep the muddy water out of the river? Do they have settling ponds? Is there any gold?
Juan, Excellent post as Always! I've a book to send you. Local legendary Lady bush pilot. Fortunately I had the opportunity to fly with her in the last years of her career. How do I send this to you? Bob
Thanks Juan! The company i work for in Alaska bought two of those ex Conco concrete boom pumps, i removed the lettering but kept the same colors. Its called Greatland Concrete Pumping. Those pumps there are very big, some of the largest made, i saw them being built at the Schwing factory in Minnesota back in feb while getting my certifications.

Thank you for all your hard work in a unbiased reporting on the dam repairs. I love the way you are including other Utube people in the area.
Thanks for great updates. This is what reporters have forgotten how to do, investigate the story.
Another fantastic presentation Juan! You put the "professional" reporters to shame!!!!!! Keep up the GREAT work.....
Awesome job Juan. Re-covered / updated a lot of the details of this most interesting CA story in recent memory. Your pioneering online coverage sets the pace for the future.

Yet again many thanks for your continued reports to this immense building site....your our man on the spot Juan, cheers mate 👍🏼😊🏆
Another OUTSTANDING presentation. Thanks Juan. - And loved your final approach and landing sequence (plus the flag). Greetings from Catskill Mountains, NY state.
I'm such a TOTAL geek. I find all of this fascinating, and so well presented.
Thank you so much for making this information for those of us who care.
fantastic reporting on this event, Thanks for the updates and keeping it informative

Progress for sure. Filled in the whole canyon. November. Keep the lights burning. Thank you Juan
Cheers Juan, great channel and that landing was a real greaser in true airline pilot fashion!
Great job again, Juan! I've followed your Oroville reports from the beginning. Your presentations are factual, contain much more detail than the lame stream media, and are unbiased. Excellent work.
Another well produced and informative video Juan ! The voice of accuracy in California news.
I appreciate you taking the time to make these videos. They're really interesting to me. Best regards from NZ.
I'm just waiting for you to ride right up the spillway. Looks like a fun Enduro Course

Nice to see another brit so intrested in this project and qualified in concreat great stuff
Thx for the derby car referral. Was fun to see them all, including you, rolling along.
Nothing but "poison oak ..." and Juan Brown at his comfortable best. Yet another fine episode.
If they get a tiny hole in the epoxy coating of the rebar, an electrolytic reaction can take place, creating what is known as a holiday. This can completely compromise the rebar in short order. But it's much less expensive than adding chromium to the steel recipe. The new Oakland bay bridge uses chromium steel because of the saltwater.
what about galvanised rebar?
BlankBrain - I agree... And I would add that the compressive strength of epoxy is negligible compared to that of steel and concrete. It is not hard for concrete grains to poke through epoxy and start the rust process. But I suppose it will slow down the rust a little.

Awesome update, Juan. The closeups and red highlight circles are much appreciated! Keep up the great work.
Thanks for the informative update. They are making steady progress.
Thank you Juan for taking the time. Your reporting and videos are always improving. Is there an Edward R Murrow Award in your future? There should be.
Juan Browne for President!.......
Just sayin'....
or perhaps a Peabody Award for Excellence in reporting!

6am. a cup of coffee and Juan with another darn good video. Love that plane.
Wow, that night shot is beautiful.... : ) Thanks Juan!
My Goodness that sure is a MASSIVE Project! Awesome Update Juan, Thanks Much!
Thank you for all you do. Stay blessed and safe. Crews are appreciated. This should be no issue. The Money should be put into saving lives and paying the professionals. God Bless
Way to go, Juan! I really appreciate your coverage of this 'pretty darn unique' infrastructure issue.
Thank-you Juan, for another confidence building, non sensational factual video. Just as we like it!
Love from Scotland. (shh, don't tell anyone, the sun is shining!)
OK... So I'm second.
Thanks for your update, Juan. Even up here in Idaho, we are watching!
The Derby Racer Brake was a hoot! That put me straight on the floor . . . if I'd been drinking milk, it would've squirted right out my nose!!!
Another timely update, Juan! Keep doin' what you do, when you're not otherwise camping and wandering backroads and vistas of the Sierra, Nevada, and OR .. oh, and earning a livelihood! ;-)
I'd really like to know who does the music for the DWR videos, and where we might obtain a copy/cd/mp3. They really should give a credit to them on their videos.
have been watching rice farmer nice to see something different thanks for telling us about him
Thank you Juan for all the great info and video. Its been a treat keeping up with this project. KUTGW
Thanks. Already whatching out to your next video.
Juan, you haven't mentioned any wildfires in your area. I have read that NorCal has been getting their ass handed to them with fires everywhere.
I know you guys had a big one about a month or so ago. Hope all is going safe up there..I'm from San Diego, and i loved your coverage of the fires, especially CDF Air Attack Div.
OUTSTANDING as usual.🐢🇺🇸🐢🇺🇸🐢🇺🇸
Amazing........... thanks for the updates.
Top-notch reporting, Juan, thanks! The "Torpedo" derby soap box car is pretty cool (will check out that video also). And what's your take on recent news about a 2 ft crack and 4-inch offset that's developed in cement near Gate #8 of the head structure? Anything you've found out would be good to know. Thanks again & take good care! 🇺🇸 🤓👌👀
Wow, grate shots from the sky. Keep up the good work.
The new terminology is upper and lower plunge pool on the Disclosure Media chat board. The lower plunge pool is being brought up to grade at night with RCC. Excavation to bedrock is ongoing in the upper plunge pool which is the deeper of the two.
man, the cost for this is staggering, the sheer amount of various concrete, metal, coated metal they need not including all the labour, machines, special machine. Absolutely staggering.
THANK YOU JUAN BROWNE! EXCELLENT VIDEO. 🇺🇸
Thanks for the update again Juan-neat-Oh. It is much appreciated.
Great update thanks Juan! Checked out your soap box derby video! Very funny but such language HAHAHAHA
Wow, that Wall fire was scary. Worried about all the good folks near Oroville. You've seen enough disaster!
is clear cutting all those trees on the right side going to create a possible potential slide danger this winter?
could cause some minor erosion, to be mitigated probably straw bales and hydroseed.
I have seen elsewhere there is need of work on the spillway gates as well. Apparently there is a crack in the concrete structure.. it's being monitored but it seems to be expanding ever so slowly.
Lawrence Haguewood Gates and head structure getting inspected and repaired as necessary.
Genuinely interested in how many rattlesnakes you encounter up near the river / dam / reservoir complex?
Thanks another great update , keep them coming
Yes I agree It's a dam fine video, but yes a dam tripod would be good☻ and maybe a dam zoom camera, love the dam luscombe footage also, This dam catastrophe has made you quite popular, as a dirt contractor myself, could you explain the dam RCC and how its made? we had a dam disaster here in 77 there's not enough dam concrete made to plug that hole, How much dam money is this going to cost, Kalifornia is going to have to implement a dam tax. Ok that's it for the dam questions and dam comments, dam fine job Juan
I was wondering, with the heat, how much of the work would need to be done at night.. Looks like good progress though!
Not sure if you noticed, but they have been stockpiling debris in a huge pile behind the RCC plant.
Another interesting video, I'm still watching these from Australia, I've no idea why :-). Also it seems so complicated to fix this I don't even understand how these things were built to start with back in the 50's or whenever. In Australia the Snowy Mountains Hydro scheme was built then, I bet they couldn't even afford to build that now.
Noticed the Radian motorglider hanging on the hangar wall. I have a Radian too, which I'm going to fly FPV.
LOVE your update, boy have your learned alot and your going a great job as a spokesman for the public!

Thank you for another great report!!
Thanks blanco - Sterling job as always !!!!
We need to get Juan a tripod for those long distance zoom shots.
Yes! and a good zoom video camera...
You said you were using a phone. Surprisingly good image in the zoomed shots. A fairly basic monopod would do the trick and it can also be used as a selfie stick when needed. Good stuff.
Someone buy Juan a Sony FDR-AX53 but maybe check if he likes that model before committing!

or just freeze frame while the audio continues underneath, or fire up Mercalli
that's a good idea!
Awesome report Juan. From another denizen of the Sierras
How long does it take for you to go from prop to jet and back with your mind/brain adj.? Thank you for the great videos And may god allways be your co-pilot..BRAVO - ZULU!

Love all the updates. I'm not near there but still very interested. Aram's video isn't working anymore?!
Chris Dowing thanks I'll check the links.
thank you for growing our food, especially great rice yummie!
It would be nice to see an in depth video on the MIGHTY LUSKUM !!
He just did one recently (check his uploads from 2 weeks ago).
That spill way is never going to fail now. Compared to what was existing to what they are doing now it is like night and day. All the degraded "red rock" removed. Virgin gray rock now as the base. This should had been done in the original. Nice report Juan. Go treat yourself to a fun fire road.
Keep in mind that prior to this years Pineapple express lake level was far lower then 700' ft. What will happen if we get another pineapple express 2018? The power plant 30,000cfs will not be enough?
Mike Ovanes then they open the new spillway, capable of 100,000+ CFS.
Mike Ovanes The Hyatt power plant number is about 17,000 CFS.
what! you mean the new spillway will be ready to accept that kind of volume before permanent completion? WOW1 then theres no problem.. did not know this fact... Thank you...
Mike Ovanes, the res level was never below 725ft in 2016. That said they passed more than the total volume of the reservoir through HPP+MSW+ESW during this last season so if they had another one like that, I'm sure they'd have to use the MSW. And yes their intention is to have up to 100K CFS capacity through the MSW for the 2017/2018 season, even if it means putting some of that water over bare RCC (to be covered with leveling and structural concrete next year).
Right around the 14:40 mark there is a reflection of water where the emergency spillway water went. That can't be left over from earlier this year. Do you know if its a active creek?
Juan, Do you have any info on the vegetation replanting plan once all this work is done? Are they thinking that far ahead yet? Control normal erosion on the face of the slope.
not yet, good question.
WOW! You're up pretty early. Another great video!
Freshwaterboy up late....pillows.
Great documentation of this project. It is always a pleasure to watch these videos you create Juan please keep up the good work
Juan you do awesome work. I am correct in that the majority of the dam and levee repair funding is coming from the country in which California is trying to secede from?
Just my opinion yep!
It's starting to take shape in a solid way, this is a relief to see. I believe they will get this all ready on time. It is very unfortunate and sad to hear that the funding did not come through... You'd think with all of the money generated from pot taxes in California that there would be no problem paying for it!😕
The Levees are being funded...eventually.
Apparently I missed the explanation of "unauthorized blasting" somewhere along the line. Can anyone point me to an explanation?
Juan, as always, excellent coverage of the very interesting project.
Discussed in the "Blasting Halted" update.
The mighty Luscombe. That's cute.
Thanks again Juan for another fantastic and informative video well done
thanks. love the updates.
thank for keep up to date
Juan I'm tellen you. You and Pete should do a little beach combing with the lake at this low level. No telling what treasures you guys could find. You are very good at explanations and keeping this series interesting. Thanks.
have you ever posted video of you flying the 777? Like an over the shoulder shot landing in UK, with sound.
cember01 I would like to, but it would require very special permission from the company, the union, and probably the FAA...though I see others have done so.
blancolirio Understandable. I've heard that drone footage that is in any way connected to revenue (like a monetised RUclips) is now being scrutinised by FAA, as it requires a license. You heard anything about that?
Great reporting, great channel btw. :)
Thanks again for a nother update buddy.
Do you know how they are preparing the aggregate for the roller compacted concrete? Are they washing the spoils? If so, how do they keep the muddy water out of the river? Do they have settling ponds? Is there any gold?
Juan, Excellent post as Always! I've a book to send you. Local legendary Lady bush pilot. Fortunately I had the opportunity to fly with her in the last years of her career. How do I send this to you? Bob
