The California Department of Water Resources issued a sudden evacuation order shortly before 5 p.m. Sunday for residents near the Oroville Dam in northern California, warning that the dam’s emergency spillway would fail in the next 60 minutes.

The Oroville Dam is the highest in the nation.

Information only. Originating with the American Thinker, it sounds like a bit of sensationalism. I have no expertise in engineering or dams or procedure; just interested in the on-going Oroville Dam problem.

Thanks.

The takeaway for those that have followed this on the detail threads over the last two years is that this dam had some inherent problems and some poor management created problems.

The sad thing is that a billion or two more is needed to save this massive reservoir in the future.

The Emergency Spillway problems and the Power House problems, that combined made the 2017 emergency merely triggered the Main Spillway deamination. It appears that there are serious problems completely unaddressed and undiscussed with the (a) main gates on the spillway, (b) sensors on the main dam and (c) leakage from settlement on the main dam.

Additionally this dam was designed in an era where the local seismic forces were not as well understood as they are today.

If California had a sensible number of reservoirs for their population, this major reservoir could be taken out of service for five years and rebuilt. However, the environmental stupidity and corruption that has been their constant companion will make none of that possible.

If I lived below this dam, I would take the repair work now as a chance to get out with some value on my property.

Hello old Freeper friend. Knew you and others would provide context and accurate info.

Had the hippies not taken over the Ca government, there would be many more dams and aqueducts finished post- Oroville. This dam was built to supply the Central Valley along with the planned growth of SoCal. In my youth, we heard there would be one long city from L.A. down to San Diego. The forefathers wanted these homes, farms, businesses supplied via the great Ca reservoirs.

This failure of even the repair is heartbreaking, vs a vs the decline of Western Civilization.

Bump for the best source of publicly available information on the first Oroville Dam crisis.

Let’s hope this time around is much less severe.

Our old friend Earth Researcher 333 (anyone heard from him?) did extensive research on the spillway gates. IIRC, he said the trunnion hinges had shifted, preventing proper gate operation.

Hoping he’s just busy. And will post when there’s something new to add.

CA_DWR⁩ with us army corps says Lake Oroville is at 854 feet. At 11 am Dwr will release. 8300 cfs down the spillway. 20000 in total with the hydroelectric plant. This will start to flow at 11am. First use of Lake Oroville repaired spillway.

Two months ago when I posted the first post on this page we were are 830 and starting to use the floodgates. The Lake is now 60 feet higher at 890 and we still have moderate spillway use such that over half of the width of the spillway is dry today.

Cahill on Oroville Dam 5-18-19

Lake level @ 890 about 10’ below level of emergency overflow spillway.

[winodog]

Marked. I have been following this on tweeter and it sure seems like they have some problems with the gates and the spillway itself

[abb]

Watching Cahill’s video. Lake is only 10’ below emergency spillway crest. He claims there are problems with the spillway radial tainter gates, and that’s why they’re not releasing water down the rebuilt spillway.

Way back up-thread, ER333 pointed out the gate problems two years ago.
