The $1.1 billion spent to repair Oroville Dam is failing as water is seeping through the rebuilt spillway threatens new mass evacuations over the risk of the dam collapsing.
According to national dam expert Scott Cahill of Watershed Services of Ohio, Oroville Dam is on the same failure track as in 2017, with visible water seepage trickling from the foot of the dam and dozens of points along the dam's principal spillway. Cahill warns that warming temperatures magnified by precipitation is a growing threat to the dam.
American Thinker reported on March 1 that the Sierra snow pack was at a record 113 inches, but another 44 inches fell in the next 10 days. With temperatures spiking this week to 75 degrees in the valleys and 41 degrees in the high mountains, dam inflows are running twice the outflows, and the water levels rose from 800 to 839 feet.

See post 46 of this thread and talk to the writer there. LOL! Maybe they can shed some light. Or, is it the same Scott Cahill? Dam if I know.
The article seems like badly-written, unresearched garbage.
For example:
“The last time the water level rose to 815 feet in February 2017 and engineers began opening eight huge spillway gates to allow 100,000 acre-feet per second to race down the face of the dam”
In fact, water didn’t race down the face of the dam; it raced down the spillway. Big difference, and if the author can’t keep them straight he probably gets a lot of other stuff wrong.
100,000 acre-feet/second is an insane number. The old Oroville spillway was rated at about 100,000 cubic fit/second. An acre-foot is 43,560 cubit feet.
Another crazy:
“The difference of the huge water pressure on the dam and the lower pressure from water running down the spillway caused the huge cement plates to rise and fall.”
Nope! The water pressure on the DAM had nothing to do with the failure of the SPILLWAY in 2017.
As a couple of people have already said, if you want to know what’s happening with the Oroville Dam, the “blancolirio” channel on youtube has reported the straight facts for more than 2 years now. Accept no substitutes.
The writer can see the future in past tense...good trick.
Bump for later
“airline pilot” “grounded”. You know that’s all some folks will see right? LOL!
Season total for Squaw Valley at 6,200 ft level 376”. At the 8,000 level season total is 621”. I believe the base is around 220 inches now with more possibly the next couple of days. That makes a lot of water.
CA wasted billions of dollars building trains when they should have been building dams. Hard to have sympathy for anyone there.
Flame on but the headline is click-bait garbage and the article is a complete crock.
The spillway is not the dam.
The spillway is not holding back any water.
The spillway is not leaking.
Thanks for link to the mammoth thread on the Oroville spillway repair! Was waiting to find the names of our Freeper experts on the dam!
BTW, folks, this cannot be good news for innocent Californians who do not vote for the environazis but do pay taxes to them.
An “acre-foot” of water is enough to cover one acre of land to a depth of twelve inches. That is apparently 325,851 gallons.
It’s all the fault of global warming and Trump.
This is NOT good
Not to mention he is a pilot..flies heavies.
A very reasonable and logical, smart guy.
Has some great videos too!!
Love it!!
Depends on how fast it melts.......
Going to be another massive wildfire year.
Wow, isn’t that a coincidence?
The webcam for the dam is down. Apparently, it too, is in need of repair. They’re awful sorry for the inconvenience.
Yikes. I hope people are able to get to safety.
[There is a LOT of snow in the mountains]
How can this be? Snow no longer falls on Earth due to Global Warming(TM).
