Fantastic job . You are part of why I turned the TV off years ago. Well done.
I am learning so much about the engineering of this project by watching your channel. Keep up the great work!
Amazing feat of engineering and reporting Juan...
On the ground and getting your hands dirty at ground zero...
Keep up the great work reporting and digging deeper for the truth...
Awesome coordination with the DWR folks on site asking questions and getting answers...
Pulitzer ~ You Tube ~ Prize ~
Thank you so much for this detailed information right in the middle of the theatre. Here in Germany we had a very special mishap three weeks ago. In the Rhine valley they are building a new double tracked railway line to supplement the existing one. Under the town of Rastatt they bore two tunnel tubes. In the final part after 4.200 m of completed new tunnel the tunnel boring machine cross under the existing railway line in a very acute angle. Between the railway and the tunnel tube there are just 5 m of ground left. This ground was frozen down to -37° C (-34.6° F) to make it drillable. The 160 m long tunnel boring machine passed under railway line for 80 m, the mishap has happened. The railway together with the road bed moved down about 50 cm on a lenght of appr. 15 m. Some tunnel segments has moved and water came into the tunnel. They had to fill up the new tunnel with concrete - together with the 18 Million Euro Machine - to provide further slides. And the realy big problem is the closed railway line. It is one of the most frequented here in germany with 200 freight trains and 160 passenger trains per day. And they assume to re-open the railway line at the 7th of october. And ... this is the realy sad thing ... we have no Juan Brown reporting from the site. So all the people interested in the oroville dam thing can be very happy to have you reporting with a very, very goog analytic expertise and also taking wunderful aerial images and videos of the site. Thank you ... keep on ... we stay tuned ;-)
pitatutube Wow! That's a big story!
Thank you for this well investigated and compact article. Since the 12th of august i was following all article in germany and swizerland concerning this mishap. The main statements are: "This indicates a failure of the freezing regime and possible over-excavation of material as the TBM passed through the zone." and "Reports in the local German media suspect that the integrity of the ground freezing operation was undermined by a recent period of high summer temperatures combined with periods of heavy rainfall." Something went wrong and they had no "Plan B". It is very expensive to tug the freight trains together with their electric locomotives over not electrified alternative lines. Passengers have to change to buses.
wow! What a mess. My BS meter was climbing as I read the article. Blame it on the weather?!? We lost a TBM here in my town when it crossed over an area of soft material and sank into the netherworld. Luckily it did cause any damage to anything else, so the causes were easy to find (the survey was at fault).
You don't have to be an engineer to see that they where cutting things too close to the limit. clearly if segments sink, they are not being supported underneath - you can't blame that on a failure of the freezing.
It appears that there are engineering problems and miscalculations in Germany as well as the USA. Thanks for that report, Sir. Yes, we are very lucky to have Juan keeping his faithful followers up-to-date. I do not see any Oroville stories in the MSM anymore. It is simply "out of sight, out of mind", as far as the news goes. (Or maybe it is "out of interest, out of the news"...) Most people have the interest longevity of a nat. When the sensation is gone, they go to the next sensational story. That's why the MSM never does any follow-up. Who cares?, they correctly reason. Maybe it is the same in GERMANY? That's why Juan is a god-send on Oroville.
It's not unusual to purposely abandon a TBM machine in the ground after a project. (with the understanding that' not the reason in pitatube's story above). Apparently it's sometimes cheaper to run them off to the side and leave them there than to disassemble and remove them.
Thanks for the update Juan, living on the other side of the country, It's so cool to be able to get this up to date info and behind the scenes footage. I am a huge fan of large engineering projects, which is a large portion of what has made America so great over the years, and this is definitely the largest one in the country right now! Awesome!
Your reporting and explanation of Oroville should be shown in J-School as an object lesson on how to do it.
I look forward to what 'mega-project' attracts your attention after Oroville.
I think the re-building that Houston is going to require would be interesting, but not quite as convenient to get flyover footage in the "Mighty Luscombe".
FYI - Juan has been doing some coverage of the fires in the vicinity of Oroville.
I agree. I'd suggest that Juan contact the University of Oregon Journalism School to have it used, with permission and pay, as a way to show how journalism is done.
James Schruben I think when Juan finishes this project he should edit his work into a format for a PBS documentary. It's really that good.
Ahhh, the "illegal" blasting explained!
The scale of the chute seeing everyone inside is simply amazing. Always a pleasure watching your coverage.
Juan Browne is a natural communicator. I wish there were more like him on UA-cam. I have struggled to view other UA-cam posts that last well over an hour, and convey a mere fraction of the relevant information that our Juan manages to convey with accurate precision and relevance. Thanks Juan.
...on target!'...
I am absolutely amazed at the detail of your reporting Jaun. You really should get a big time journalism award for this work. Real news from a real journalist.
As I read through all the comments and praise, it's hard to find room to say something different that hasn't already been said. I really do believe this is award winning content you've developed on this story and not the local award you mentioned in a previous updates, but at the national level. Maybe someone closer to the journalism industry can offer this storyline up for review to the right governing body. The channel grows stronger everyday with additional lines on the Butte County fires, Cycling tours of Northern California, Oregon and Washington, etc. the list goes on. I guess the only words I can find are a simple "Thank you" and "Outstanding meaningful content that enriches our collective knowledge of the world". Well done.
I live in Australia and have followed Juan from DAY 1. i LOVE his superb, factual reporting .
It has made this amazing project so interesting and fun to follow...........I agree Juan should be noninated for the TOP jouranlim award in the U.S.of A. Take care all.
You not only asked excellent questions and brought great clarification to all aspects of the project. but it also appears that you brought a high level of rapport to the mix. These people really seemed to enjoy interacting with you. With this level of reporting you hardly need to apologize for taking a week to do it!
This comes from mutual respect. Which is why the traditional reporters, who had actual knowledge of what they were reporting, would do such good interviews.
Juan has structural knowledge and has shown he is keen to learn more, plus only reports in a factual manner. This puts the people being interviewed at ease, as they know their words won't be misconstrued or deliberately misquoted to create a lie.
Another awesome video full of information about the reconstruction. Thanks for keeping us updated, Juan!
This is such a large scale project with minimal time for planning & execution. Lots of areas where problems can and will occur. No one should expect perfection.
As explained by DWR supervisor Tom Cobarrubia; the drainage pipes are mainly there for subterranean sources of water and NOT the incidental leakage in the expansion joints (starting at 1:42) but then in his example of witnessing excess drain water he mentions the construction joints that the pipes call home, as needing further inspection (at 2:20) to determine where the water is coming from and damage assessment.
Now, it makes sense to me as to why the spillway would need drainage (next season's construction) through the section of RCC that clearly, could not have a subterranean source. It would tell the inspectors that the grout seal and rubber seal BETWEEN slabs has been compromised and is in need of repair or maintenance. A way to stay on top of any water related future erosion!
Thanks again Juan Browne, for your timely updates and thorough questions about construction.
Mr Juan, Hat 🎩 Tip. People will talk with you !
That's what makes you so effective, thank you for your efforts 😄 👍🏼👍🏾👍🏼👍🏾👍🏼
I don't know which is scarier: the fact that somebody okayed the building of the spillway on that type of base (dirt on rock layers) in the first place, or how in the world it has managed to hold up all these decades... It really is an incredible job being done in spite of/ in addition to the time constraints. Thanks for getting us up close and in person and explaining it all for us.
Juan, I absolutely do not recall seeing any channel with so many accolades regarding the investigative and qualitative reporting of an incident or occurrence. They are all completely deserved! When you began this journey I don't believe any of us expected the thorough and informative results you have provided. I have gained a level of understanding and appreciation for Oroville and other similar projects that is not likely possible from our normal reporting media. On my part, your efforts and reporting are abundantly appreciated! Nick, North West Farmer
Juan I sure hope you get some kind of an award for this coverage of the repair. Excalent can't find this anywhere else great job
Juan, you really do an outstanding job! Please, do not ever work for "mainstream" media...unless you decide to start your own company! I really appreciate all your hard work, its very informative and enjoyable! Carry on!!!
WOW... talk about a multifaceted project, literally they are building a gem here. Not to say this couldn't have been built this way in the 60's but it is high time they get it right on this go
Thanks Juan, great reporting as usual
So cool to have some genuine footage of what is going on down there. Must have been interesting to wander around the spillway with the project big wigs
it is because it is not the government. it is a utility.
Actually, the CA DWR is a government agency. water.ca.gov. I manage a CA government agency and interact with them.
Unbelievable. This is not just "pour me a new spillway with concrete on top of rock" this is layer upon layer of technical concrete. Every time I see an overhead shot the size of this is amazing. It looks 1/2 mile long.
Over 1/2 mile wow!
what I find mind boggling is how much money has been spent on this so far to fix a tiny little crack that just eroded into a massive size hole.
+MLTomson ... This is what the power of hydraulic cavitation can do when proper maintenance is deferred by incompetent governance of otherwise good management.
.65 miles - take a look at it on Google maps. The images are before the failure. So very different from the current condition.
Not to detract from parts I and II, but this was the most informative report to date. We now know what was actually meant by their term "unauthorized demolition". Not nearly as bad as was first conjectured. The explanation of the drains and how they would be monitored, to the formation of the rest of the spillway for this year was excellent!
Thank you very much, Juan. Just outstanding reporting!
The 'beef' so to speak...
It dates us to say we remember that commercial! LOL!!
I just couldn't see how anybody did any shooting on THAT job as a sneak deal. 'NOW we see 'said the blind men to their deaf and dumb wives.
Like when you cut into the steak before the Blessing.
I'm sharing these videos with the District Manager of the Palmdale Water District, because the SWP water for Palmdale comes from Lake Oroville.
The accurate information provided about the spillway repair affects a lot of people, not just the residents of Palmdale.
Thanks!!!
David Palmer yes it does!
This is the most important construction site in America. Thanks for the details and film footage blancoliro. Awesome coverage.
Fantastic Part III production, Juan! The enormity of this undertaking is breathless and you bring it into more understandable perspective, as well as explanation and description of phases of the reconstruction! The critical importance of Lake Oroville to the State of California cannot be underestimated or underappreciated! Thanks so much once again! Looking forward to Part IV, when you get to it!
Thanks Joan!
WOW! I love watching stuff like this,like being in school but actually interesting to watch,my dad would have loved to see this as he spent his life in construction. Awesome job Juan.
As a "Browne Noser" of the (( JUANNABES )) Club, great job..Juan Browne !!
id be upset if you dont get an Emmy for all the work you have done on this
Yes, this is the type of journalism that should win awards. I've been following Juan's coverage since the beginning and it's been outstanding throughout. He's articulate, has studied his subject intensely and never asks a stupid question. I admit, at the beginning, I was skeptical that Juan would get permission to do the in depth investigation and reporting that he wanted to do. Now, I have no doubt concerning the transparency of those who control the Oroville rebuilding effort. The geology of the site, scope and quality of operations, planning, financials and the identity of those who are responsible for its outcome have all been covered by Juan. Well done, Juan! As a big fan of "low and slow" and STOL, I enjoy your videos featuring the mighty Luscombe as well - thanks!
There's a reason for the doom and gloom. People are so used to government and corporations operating opaquely. It's been their modus operandi for as long as I can remember. From the void of true information, people naturally discuss what is being covered up. In such an instance, I don't think it's unreasonable to assume there's a cover-up - otherwise, they'd just tell us what's going on, right? Well, that resulted in most people assuming the government was not doing what it should be doing. I don't think that's a bad assumption - even if wrong. It's what opaque actors deserve for their disrespect to those of us affected by their actions, or lack thereof. By contrast, allowing someone like Juan to delve into the details on what could be the biggest feat of engineering and construction in US history fills the vacuum of information that would normally be filled with theories that assume the worst. It looks like those responsible for mitigating the initial disaster and actually fixing this situation in such a tight time frame are going to come out smelling like roses when this is completed. They will be richly rewarded - and they should be. Not only for pulling off such a magnificent feat - but also for doing it in such a transparent manner.
I think all these dam segments that you have done should be edited together into a 2 hour Independent film documentary that is submitted for an Oscar.
Juan, great service and explaining to the non-engineers is simple terms. I have been following since this disaster started in Feb.
Thank you so much for keeping us informed about the progress of the dam's reconstruction. You are doing a great job!
Fascinating --all the aspects of this project, especially the different types of concrete being used, hardeners, cooling, delivery systems, etc.; all of which is a separate, huge topic -- exploring the chemistries of concrete.
Thanks so much, Juan!
Great reporting and information. Amazing to see what technology has provided for the construction trades .... especially Concrete technology.
The reporting has been incredible. Great Job. Also glad that Jeff Peterson landed on his feet after he and Craig Ferguson left late night.
Thank you Juan for your dedication to this project.
Juan, it's amazing how quick you are picking up on the technical side of this project. You're asking all the right questions for us and, at the same time, we are all learning how the dam operates. Very cool.
As a side note, they sure didn't seem to like the term "unauthorized blasting". I think they wanted to change the subject.
ChicoDon Anything those guys say that is recorded can be used later by lawyers if someone decides to sue. So they are VERY CAREFUL about any statements. Also they have to deal with the federal regulators, FERC, and don't want to come across as willfully ignoring regulations. "Anything you say, can, and will, be used in a court against you."
Damn, just can't put in words how much I appreciate the effort and time you put into this. Can't get enough of these shots and info. 👍🏻
Yet again, another great video with lots of details, access to managers who really know the project inside and out, and of course great still shots, fly-over video and stills. Very well done! The little curious boy inside me wishes I could have been on that walkthrough, and take in the spectacle of so many parts to the puzzle taking shape rather quickly for a large construction project. I feel more and more confident they will build a lasting fix for this whole mess. Hopefully, cross your fingers everyone, mother nature will cooperate, everything they build will hold up until the final fixes next year. This is fascinating stuff!
Thank You for your hard work on the Orville Dam project. As far as I am concerned your are explaining things very well.
Great video "Blancolirio"....keeps us feeling confident down here in the City of Oroville....looking forward to part 4........
Great job Juan! Very informative and interesting! Thank you for taking this massive project and reporting the details. You should be proud because no media outfit would touch this. You deserve a medal and acclaim for your work!
Juan Doing a great job as usual! Looking forward to part 4. Thanks to you and your family!
Wow! That is a wall. Makes it look big next to my little retaining wall I build around the house. It was a full 2' tall and 6" wide but I did it all by hand with a mixer and a few hundred bags of concrete. Doing the rebar like they have is amazing. Guess they had cranes lift those heavy pieces. Amazing work and speed. They are building walls 5 times faster than on I35 here in Texas. Just amazed at how much of a mass that spillway is. The flow rates out of Houstons dams releasing water is flooding out a whole area downstream at 16000cfs. 160000 cfs is hard to comprehend. They slowed to 8000cfs to keep the damage downstream to a minimum. That is alot of water. Your videos are extremely informative. Thanks
What a great tour from Kiewit engineers and DWR..!! Fantastic job Juan..!!
Your hard work on these videos shows. Great information and excellent presentation. Thanks for your continued coverage of the construction.
I can tell that Jeff Peterson knows what he's doing!!
Juan your videos are better and more informative than history channel engineering series
Great work! I love the continuing play by play of the reconstruction of this spillway!
Well done Juan! You really get deep into the technical nature of all the processes that are being developed and implemented here. That is your genius! You provide such a thorough and in depth analysis that it answers ALL our questions! Thank you for the informative news! I look forward to each new video, and, I have to tell you, In my opinion, I think Kewiet is doing a good job. That comment comes solely from your unbiased reporting, but all in all, progress is being made! Thanks again for you tireless reporting!
great information job , Juan ; and once more thanks for the subtitles ,there are so many technical words ! Juan , you are my best american-speaking teacher !!!
We were starved by DWR in the early days of this event. Answers were few and vague. Remember early video from DWR? It wasn't long enough or wide enough, amature, unprofessional. And they still don't narrate. How are we supposed to know what's happening? Watch this channel. You keep pressing for more and accurate information on behalf of all of us. Great job! Best of three parts.
Good job. Personally I would like them to have to use the spill way this winter because even though we filled the dams this year the underground aquifers could use more water. And one more really wet year would do wonders.
Oh don't worry about that, the Hyatt PP will be flowing full tilt at 17,000CFS plus!
They don't need the spillway to flow a lot of water, because they have the HPP and RVOS. They need to keep the levels lower than normal, so whatever comes in will likely be pumped out by the HPP. What you will not have is a lot of excess water next summer.
Great on-site tour that shows us YOUR commitment to this project, Juan!
Truly amazing work they are doing. Your coverage / reporting is fantastic. I look forward to each report.
Wow, access to the ground works :) That is totally down to your fair and honest reporting on this project.
Thank you Juan. I really enjoy your videos and have watched every single one of your Oroville series. I love this stuff.
Thanks for posting this. I am envious of those who get to work on jobs this big.
Nineteen Minutes in the Real World.
_Thanks again Juan!_
Great work as always Juan. Aside from the great information - clearly and concisely delivered - I think you should be recognized for how much your reporting has contributed to the high level of dialogue and conversation in the growing "Oroville dam community". There are SO many people watching and learning as this project proceeds and I notice that virtually all of the dozens of comments here are intelligent and thoughtful.
There will always be folks who just want to snipe at the process but I believe that your true value has been bringing the level of discourse up for everyone who truly wants the facts and to be informed. Thank you for continuing to bring questions from the "watchers" to the people who can answer! I have seen numerous examples where those watching have voiced legitimate concerns and questions that you have raised in your reporting and have gotten answers directly from the technical experts. That in itself is a tremendous service to the residents of Butte County and the surrounding area along with all the rest of us who are watching around the world.
Keep up the good work!
Thanks Beth!
WOW really big job, you getting that tour really shows every one how big it is, keep up the great work on covering this for us. I'm in Connecticut and we never hear anything about the Orville dam It is nice to have someone on the ground and air letting us know what is the update is. Thank for your time covering this.
Excellent stuff blanco ! Wonder how many ppl working there watch your vids , showing their family's what there doing each day ?? - My guess lots - Thanks again for all your fantastic work !! I love this channel !
Thank you Juan, DWR and Kiewit for providing this information.
All I can do is echo the great comments already expressed. Thanks, Juan..!!
Well done again Juan, another factual and responsible report. I have to say well done to those on the ground who have worked bloody hard in hot trying conditions to advance this project to the stage it's got to now. I didn't consider them a chance to complete this by November 1, but right now they're giving it a shake. Whether they make Nov 1 or not all the workers deserve a big thanks for doing their best.
juan is a man made back in the day when men knew how to rise to any challenge so you youngin can learn a lot from this type of man the sky is the limit reach for your goals and never set them too low. I find in today's society the young men today only reach to height of there knowledge when they should expand their knowledge to reach any goals.
keep doing what you're doing man! these videos are great unbiased reporting. I show them to my students. Thank You very much!
Juan, thank you for keeping us informed.
More great details Juan - thank you. The DWR rep made it sound as though the additional 270' section of upper SW where the "unauthorized blasting" was done was in fact planned to be done this year - which I don't believe is what we assumed and/or were told earlier. Rumors rumors rumors.... anyway, the work looks top notch.
that makes a change an engineer speaking english. keep it up Juan great to see what is going on
Awesome video! What a great country we've been given.
Awesome video Juan! I've been checking daily for the new videos! Keep up the great work brother! Have a happy Labor Day weekend!
Awesome work!!!
Really nice of those guys to give you such a great tour.
Thank you and them.
Wow Juan! You really did get unprecedented access and you made the most of it. This may truly be your best episode and leaving what you call the best for last in episode 4? Is a nice touch. Excellent Reporting Job and Keep Up the Good Safe Work Captain.
Awesome Juan and fascinating - a really great series. Thank you.
Beyond excellent! Of course you have laid the essential groundwork. While the so called professional journalists have asked about the green spot and security considerations that are classified, you have asked mostly engineering questions that move the narrative along. The phone in conferences have been enlightening. DWR knows you are the only channel that will get their story out. Hence, they are giving you the graduate level tour with the real bosses and not the dumbed down, lawyer approved, spokesperson delivered version for the unenlightened. The other reporters present seem to be content on letting you ask the questions and just taking notes so they can get a few quotes. That is a good strategy when they are in over their head. They are not stupid, just ignorant.
No, jounalists have proven they have a lock on both the latter attributes.
Juan maybe you should see about documenting other massive construction projects its really cool to have a insight about these great works of engineering
Can't wait until part 4 that's what I've been waiting for to see how they feel that up with the RCC. 🐢🇺🇸🐢🇺🇸🐢🇺🇸🐢
Thank you for sharing your amazing video, and thank you for the great effort you have done. It's very interesting to follow your video and your explanation.
Fantastic work Juan with this movies. Can't wait for water relese. Greetings from Poland.
Thanks Juan. You COULD HAVE BEEN SAILING !!!
Glad that the nature of the unauthorised blasting has finally been cleared up, the terminology makes it sound like some guy got bored and decided to plant some explosives on his lunch break.
It has taken you over a week to upload the videos and we sure appreciate it.
I am shocked by the aerial photos of the spillway. I always thought only half of the spillway is affected. But it's more like 90%.
All of it...
Not all of what you see being replaced was actually washed away this winter. Portions were still in tact and were demolished later as part of the overall rebuild.
Thank you Juan. Always educational! 🇺🇸
Another great report!! Thanks Juan!!!
A great photo - op during this project will be when the new lower chute concrete comes in contact with the new upper concrete chute. It could be portrayed just as was the golden spike ceremony at Promontory Point Utah when the trans-continental railroad was joined.
I am so envious of you. It must be a kick getting up close to this engineering marvel. Also, your videos make me think the contractor and agencies have their Rock Stars on this project. (Pun intended) Thank you, and if ever need an assistant to carry your camera stuff, sign me up. That also includes flying in the mighty Luscombe.
Juan,
I would appreciate a cross section showing the typical placement of dental concrete (grout slurry), leveling concrete, roller compacted concrete and structural concrete. Even a crude, back of the envelope drawing would be helpful. Over the episodes I have become confused as to the layering.
Another "cartoon" drawing that would be helpful would be showing what will be removed and replaced in the lower spillway after this season has ended. The need to cut in the drainage system is confusing me as to the depth of what concrete placed this year will need to be removed, and how far the cuts will have to go for the drainage.
Thanks. Excellent reporting.
Thanks for the tour. See you next time.
Juan, thank you so much for these fantastic videos. You're doing a great job of asking intelligent questions to the DWR that help to clarify what they are doing. Very interesting to hear that they will remove the RCC training walls next year. Also good to hear an explanation of the different types of concrete and how they are used.
I find it interesting that so much of the spillway is temporary and will be replace next year because it may be needed this year. As I understand it in 50 years this is the first time the spillway was needed and if you have normal precipitation this Winter they can work all winter and Finnish next fall. My point is if somebody knew the feature they could make some real money in Vegas
Thank you I see that this step is necessary.
Well can not say how much we enjoy your videos Jaun. Seen the one you made for Houston good job, but most of the people in Houston were trying to get out made us all understand what the real troubles they are having to much water no place to put it lol. thanks again keep them coming bro.
Thanks Greg!
Thank you Juan comprehensive reporting. Not a problem at the moment because the weather looks so good, but if there is any frost it can destroy concrete like a hot knife going through butter. Cheers.
That concrete has so much mass, it would easily survive a sudden frost event. It's not a 4" driveway......
Yes i agree but the top 1 inch can crumble over night it there is a heavy frost. Which can leave the concrete vunerable and in a more exposed state. It takes 25 years for concrete to fully harden and another 25 years to loose most of it,s strength . Thank you for your comment.
Thanks for the magnificent coverage!
thanks again for all your work reporting on this project!
Cummon guys, give Juan a thumbs up and let's see if we can get this video trending.
Thank you for your awesome reporting.
Very interesting operations going on.
Excellent view of the process. Thanks!
