It is a JOY to see someone who truly enjoys their life. Excellent Video.
I worked as a surveyor on Oroville's sister twin dam, Eagle Creek just West of Indy. We used compacted concrete on the upstream side of the dam. It was 100 ft wide and 50 ft thick stair stepped up the slope. 25 ft below to 25 ft above the normal water line. Each layer was bonded into the previous layer by the action of the rollers chewing up the top 12 inches and you couldn't tell one day's work from the next. From the top of it to the top of the dam regular soil was used and bonded to the top concrete layer by the chewing action of the compactors just like every other layer in the entire dam. The slope was shaped with bulldozers days later. It was hard, but not like concrete in a street or a driveway. It could be shaped and graded like real hard compacted soil.
It was to prevent wave erosion of the dam around the permanent pool level. It was made in a pug mill (like a big mixer or shredder) using screened material excavated right off the stream bed, screened for large rocks and mixed with cement. Rolled in with sheepfoot rollers just like compacting the soil for the majority of the dam. It was very dry, as concrete goes, just slightly more moisture than the soil for the main dam.
Sounds about the same way Oroville is going to be done. They got 1.7 million yards to work with. Some one said Friday they already have a crusher / screen working on site.
Different mix designs will have different characteristics... using a sheeps foot roller over a smooth drum would certainly leave a rough surface... If they were able to shape it with a dozer yours sounds like a very lean mix.. maybe similar to a dry version of CLSM?
Thanks for that info. The spillway is the obvious problem. What can you tell us abut that? What is under the spillway? What strength concrete was used? What is the rebar and configuration? I don't claim to be an expert but these are the questions average people ask. More important, what shortcuts were taken and who was paid off to okay it?
I think it's obvious that the spillway was built on a hillside comprised of rock and dirt... it appears to have been mostly dirt in the area where the failure occurred. There does seem to be sections where the slab varies in thickness. I'm not sure what minimum thickness was called out on the plans but in the center (where the failure occurred) it appears to be 1' or less. If the contractor didn't follow the plans then they are at fault. Also there should have been some kind of inspector on the project so I guess whoever was inspecting that phase of work would also be culpable. DWR has the original plans.. I'm pretty sure they know what thickness the drawings call out... although I doubt if we will ever know the real truth.. Also why was the DWR patching cracks on a spillways with water seeping out from behind it yet failing to investigate what was going on under that slab is a real mystery and I imagine they will cover their asses on that one... BTW I had some crane operators who worked on the dam and they would tell some crazy stories about what it was like to work on that project... One story that sticks in my mind was a crane / dragline operator who was a bad alcoholic.. one day there was nothing to drink so the guy started drinking gasoline as a substitute for his booze... Another thing that happened a lot was fights.. you didn't get to work if you weren't tough as iron... Lots of good ol boys on that project .. I can see how some minor detail like the correct thickness of a slab could easily get overlooked.
John.... Apart from varying thickness and QUALITY of the concrete, some of the earlier reports on the core drilling suggest that the concrete is much thicker ( over 4 feet ) than was called for in the plans. By comparison airport runways are 4 feet concrete and they take a much greater beating. They would have prepared a road grade road bed and poured the concrete on top of that. One thing with concrete is that once it's poured you can't overwork it or it goes bad, and there are no tests for that. The actual pressure on the spillway is not that great. 27 feet of water is only 12 psi, less than one atmosphere. It's moving and a live load, but still.
I have to say, your channel is now my favorite in all of UA-cam. Catching up on your older stuff with dirtbikes and flying but these Oroville reports are pure gold.
Nice conveyer for the return to the top of the hill. Looks like a lot of fun!
The way the world is at the moment, there is nothing better than seeing some kids having fun in the snow. Thanks as always for the updates.
Snow-tubing, such fun!! A big thumbs up for the great reporting, Juan, thank you again 👍😎
Thank you. Wish the evening television news was this informative and enjoyable. Watching your channel is like a breath of fresh air.
Thanks. That bit with the kids playing was a nice relief from all of the tough news we have had to deal with.
Juan good sir,another well done report and I agree that you certainly do the human interest storytelling too. Naturally! I'm a avid outdoorsman myself but with disabilities and even some help from other Veterans and friends sometimes it's just too much at one time. Here is my point; Have you ever considered doing any documentary projects? Any documentary genre at all because you're certainly gifted and as honest a person I have ever seen.
I would love to corroborate on a documentary.
Woohooey! Snow tubing with the little ones is too precious for words. Brings back my childhood memories of doing the same, in the same area, but no fees. No lift, either. That looked awesome, wish they had that back in the day.
We used to visit family that lived in Donner Pass, and I well recall the high snow bluffs piled against the cabins. We all knew what happened to the Donner party...
What a beautiful day you filmed there, with new equipment for an intrepid citizen reporter bringing us the real news.
The Oroville Dam crews sure have their work cut out for them.
Thanks Juan and Team Blancolirio.
My old home town (1939) Truckee thanks for the memories Donner and all.
I look forward to every one of your reports. Thank you so much.
Thank you for your reporting and for giving me a smile today with you and Pete tubing!
Here in New Zealand I have found the whole series very informative and entertaining. Thank you for your 'hype-free' presentation style. We are moving into winter (not like yours I might add) and it is great to see how the other side of the world is coming out of its winter.
Thank you for continuing to report on the dam and the rainfall/ snowfall. We are very keen to keep informed of the precipitation vs drought in your area and I appreciate your thorough and informative insights. Please keep up the great work : )
Fantastic! Learn about a totally new subject for me, layering concrete and great family fun as well. Couldn't be better, thank-you so much Juan.
Takes me back to 1945, when I was the 8th grade at the Lake Van Orden school in the snowsheds on Donner Summit. My parents worked at Rainbow Tavern and I lived with C.B. Crampton and his family at Crampton's Lodge (across Hwy 40 from Hampshire Rocks State Park on the bank of the Yuba). Thanks for the memories. I also enjoyed making Spot Landings with you in your Luscombe. Long retired from flying, I still carry my Commercial SE&MEL ticket.
Wonderful, absolutely wonderful to see your lovely children & you having fun on the slopes. You have my respect, sir..!!
RCC uses less Portland cement per mass of aggregate but achieves greater strength due to low void volume. Just like gluing a wood joint where high clamping pressure results in a very thin bond line, LESS cement and high compaction makes it stronger. Approaching the strength of the parent rock of the aggregate. Cylopian mortar method achieves strength due to the macro aggregate (boulders).
I like Juans man on the street approach with facts and shots of the areas out west. No phony baloney reporting. Good job.
Juan has a paypal link in the notes. He's not really asking, but there is a cost involved in time, travel and equipment. And his reports are certainly valuable. If you look forward to Juan's videos like I do, why not throw him a couple bucks? If enough of us do, it will add up. Thanks again Juan!
Thank you for sharing Juan.
It is fantastic to see you having fun with your family.
More storms coming into Northern Cal today . Nice to see the deep snowpack at Donner. Sugar Bowl is one great place to ski.!!
Thanks for the report. You were having too much fun on those tubes and Pete. What a grand time.
Thank you Juan, sending you a smile.
Excellent report as usual. Thanks for the enjoyable mix of current interest, historical interest and mental vacation. Who knew that just watching your pack having fun tubing would be great fun as well?
Your reports about the Oroville dam are the Best. I have been watching them for weeks now. It's good to know just what is going on there. The national news never says anything about the problems that are still going on. Most people think that the worst is over. There's big things that have to be done to permanently fix the spillway.
So fun! Your grandkids are so fun.. my favorite vid is the kite flying day. Sledding is also awesome. FUN FUN FUN!! The world needs more fun!! Thank you for sharing Juan!!
I think those are his kids, not grandkids.
FYI: I think the kids are HIS kids, not his grandkids.
Thanks for the update! My apologies .. I have grandkids on my mind I guess.
Thank you so much for all of your videos! It's been so hard for us to learn what's really going on here. I appreciate how you lay out the facts.
Oh Yum. Well done, as usual, Juan. Big you and little you in Pete. xx
Oh no ... another storm. Oh please Lord, let that spillway hold through this spring runoff.
Always, kudos to the hard workers who ensure the damn dam behaves.
Standing by. C
Thank you, Juan Browne !
Was a beautiful day up there with su Familia !!
Loved it !
Oh what fun in the snow, and they even have a conveyer belt to take you back up? What luxury. Loved the report. Another great job.
Thank you Juan for another excellent video. Your reporting is truly appreciated! I'm also digging the historical tidbits on the region that you've been adding. Anyone up for a game of Trivial Pursuit?
Anyway...I just wanted to thank you for providing the public with updates on the situation up there in Oroville. I've found each update be very understandable; timely; and most important, accurate. Thanks for stepping up to the plate where the DWR has not.
Looks like a blast! Even with a moving sidewalk to take you back up, can't beat that! Still looks like a Christmas card scenery up there. All that snow will help provide relieve for drinking water problems down in the valleys.
Always fun seeing young Pete!
JUAN, just loved this video seeing all the snow and a happy family tubing in the Spring. We look forward to all you posts.
(New York State here, near the Catskill Mountains)
Juan, my wife and I will probably watch every video you ever put out, they make us smarter people!
Fantastic! Watching the Oroville situation, now from Honduras (where snow is unknown.)
Thank you Juan!
The new mike works great! Thanks for bringing us all along for the fun.
Always fun to take a break and get a little history lesson ! Great ending Juan , thanks as always for sharing some deserving R&R with the family. Stay safe ,on your adventures.
Thanks for the update Juan, with some fun mixed in!!!
The sound changes as you turn your head. The information given should be important to a lot of people seeing that our infrastructure is needed everywhere. Thanks for the updates!
Yet another fantastic update ! THANKYOU
Juan the new mic setup sounds great. Thanks for your time and energy to put out these great videos. Keep up the good wprk. looks like pete had a great time snow tubing. I look forward to the next video.
Amazing scenery up there! Thanks for sharing your family time with us, looks fun!
Very nice video! it's good to see some of my old stomping grounds; been gone for 25 years! my father tended grounds and the bar at Rainbow Lodge, after discharge from ww2. thanks again:-)
Wow!
Also, as always great job on the coverage, and more importantly, great job show the family a great time!
Thanks for your videos, my third cousin and her family live in the Nevada City area, and your videos explain what is happening in the region.
Thank you for your great update and including us in some kiddo fun! Much obliged!!!!
beautiful country. Thanks Brother
Great boots-on-the-ground story, and impressed with your cub reporter assistant!
Great update again with some family fun to boot. We had 2" of rain from our rain gauge in Oroville where we live and are keeping am eye on inflow/outflow data every day, my concern is getting it rebuilt the correct way now, up to current standards & since I'm one of the average people looking for answers,that will satisfy me with being inspected and passed when finished. Coming to you from Evacuation Area 1A, have a great day..
What a beautiful looking place
Thanks Juan.
That was a great report Juan. Little Pete is such a cutie.. and that looks such fun.... Great job...
You walk on water.
Thanx Juan and family!
Really like your channel. Very informative, quick and easy explanations, great photography and narrative. Big thanks for all your hard work to keep us informed.
Great Job! From your first explanation of the dam conditions. Your reports are intelligent and relevant. Seasoned journalists should be watching to see how it is done. I appreciate the introduction to Aram Bedrosian as well.
Juan Brown you sir are truly blessed God Bless you for your common sense reports👍👍👍👍
Thank you for your detailed reports. Keep up the good work my friend. It's not easy for sure, you do an excellent job buddy. 😎
What a picture of success!
Its all Good . Audio Juan thank you much.
Love you and your family! ✈️
I appreciate the historic info of the area... thanks.
Awesome, very professional report as usual.......but what made me smile is your son having soooooo much fun tubbing. God Bless you and your family =)
Another great video, and beautiful family. Gratias.
I remember watching them using the Rotary snow plows up there kinda cool to see the current amount
Gracias Tio Juan
New Mic works well, they are a bit directional so positioning using the lapel mount it is a bit critical to get it facing your mouth. Good info on the RVOS too.
Yes!! I gotta be careful mounting the mic on the shirt.
blancolirio agreed - better to face mount it - easier for your style of reporting. Great job!
I've never had 11mins 7 second disappear so fast! loving your videos all the way from Northern Ireland! Keep it up!
thanks for the updates
thanks Juan and enjoy those kids!
Norden is my old stomping grounds as a kid in the early 1950s.
Thanks JB sound is good , you do the best job!
Very well done!
Thank you
Great channel mate. Keeping it real while a very precarious situation unfolds around you. I will show my kids some snow one day! Rod from Australia.
Nice Irish music in the background. Wonderful scenery and wonderful family. Lucky you!
Pete has grown since he "piloted" (and fell asleep) the Luscombe in another of your videos. And the new mic makes such a difference. As usual, a nice video of you, wife and kids.
Nice job, Juan. Really enjoy your comments.Looks like you may have another calling when your day job runs out.
Another great update Juan - all valuable material.
Thanks for the information.
Great video !! Love the kids having FUN :) The snow is Beautiful :) The trees will appreciate the nice drink !!
Love the way you get your family into the picture! Pete is tooo cute! Great little partner you've got there.
Awesome video.Good times with the family nice.
Enjoyed the young ones having fun.
Another excellent update. Your reports are way better than all the MSM and official stuff. Many thanks :)
Beautiful country. Thanks for the update and the video.
Beautiful up there!
Brings back about 60 years ago--thanks
Wow, add 5-more inches of rain and/or lots of snow, which will eventually melt, hopefully not all at once. Thanks again for a GREAT JOB you are doing, totally appreciate it. Finally, the real-skinny on this, information I can trust.
Good man blanco !!!!!!!!!!!!
Love the way your sharing this !
Fantastic !! Thank you !! Donner Ski .....absolutely love it......
Looks like the BIG kids had a great day out with the little ones. Really enjoy your videos. Cheers from the Hoosier state (of confusion).
'Ol Pete is a tubing Champ, you guys had a blast up there!
You're doing good work, Juan!,
Fun times ,all we got in reno was 60 mph winds on "Fri as usual,very little rain.But we like it when the snow stays up top.
following you for 2 months now, great job, keep it going, I don't think this DAMN story is over yet.
Wonderful! So well done!
The music and fun with the kids is a nice touch to your informative vid. Enjoyed...
