California's Lake Oroville Main Spillway Severely Damaged/Eroded. Oroville Dam's Recently Reconstructed Main Spillway Fundamentally Flawed

854.70 AT 9 AM...NO RELEASE DATA YET..

THEY R LISTING THE OUTFLOW AND INFLOW NUMBERS AS BASICALLY THE SAME!

DID THIS STOPPAGE HAPPEN NEAR THE END OF THE HOUR?...JUST BEFORE...?

It looks to me like DWR has shut spillway gates 1, 2, 7 & 8. Probably a work-in-progress to shut spillway down entirely. WTF? Inflows from snowmelt are up to 35,000 CFS, a 50% spike in last 24 hrs. If something is wrong with the spillway DWR needs to DISCLOSE IT NOW. #OrovilleDam

If the spillway breaks apart again it could last through another cycle...will they build it again?

That inflow spike is due to rain, and will fall back to baseflows Wed/Thursday.

no, they have monitor it all because they are orchestrating
the release of water from a whole bunch of damn in the Region,
and they have to do it in such a coordinated way so
they don't flood the valley.

Is this some kind of pump to the side of the spillway? If so, not good.

This is a new twitter account, and the guy just posted it without explanation. I'm assuming he captured it from the Dam Cam.

This Littlepixie really hopes that the Oroville dam isn't responsible for any of this?



PS: there is no sound to the video.

857.01...NEW NUMBERS IN 5 TO 10 MINUTES!

there is a shocking lack of mass media updates last two days after so much last week

THIS WILL PUT IT AT A RISE OF 2 AND ONE THIRD FEET IN 23 HOURS!

NUFFIN 2 C HERE....'YET'.

Jack in VA is great. Read the latest observations. Something fishy is going on.

858 feet!

858.76 NOW

Oroville releases now down to 10000 cfs.

Shasta now at 40000 cfs.

Shasta has a crack in the face that's concerning folks...check this out..they say don't worry of course. The guy they interviewed didn't sound convincing to me. I think this rickety old dam could easily fail..in fact this is what our masters want anyway.

Good find! I haven't heard about that.

That lake is FULL. 4 million acre feet, any failure would be catastrophic downstream in Sacramento. Need to monitor this situation for sure.

Bump for dam doom.

You would think after watching the Nebraska failure, last month, they would be more cautious and share data.

Ego...it’s a bytch.

Jack in Va did some updated maths

Whoever found him.... thanks! He was a good read. I can’t view the dwr cam so I have nothing but numbers.

860.5 feet

maybe all the dams can'tdump their loads at the same
time, so they have to do it sequentially.

The Department of Water Resources has stopped releases from the Oroville Dam Spillway due to forecasted dry weather.

BUTTE COUNTY, Calif. - The Department of Water Resources has stopped releases from the Oroville Dam Spillway due to forecasted dry weather.

The department began reducing the releases on Monday, April 8.

On Wednesday, April 10, flows down the main spillway were reduced to zero at 1 p.m.

Releases from the newly reconstructed main spillway began at 8,300 cubic feet per second on April 2 and peaked on Sunday, April 7, at 25,000 cubic feet per second. . .

Oroville has only received 2/10 of an inch of rain in the watershed in the last week ... so all the water coming into the lake is snow melt.

Snow melt rates are very predictable and with no rain now in the short term forecast I am sure the dam operators feel comfortable letting the lake level rise a bit so there is more storage for the summer months.

After years of drought California is necessarily concerned about a LACK of water in storage, particularly since it's population is now MUCH higher than it was at the time the last major water storage dams, including Oroville, were built.

Build a very populous urban society in a desert ... and voila water becomes an issue.

Wait until a 20 or 50 year drought hits the west, as has happened per the geological records, during the last few hundred years.

WHEN, not if, that happens much of California, Nevada, Arizona, Utah, New Mexico, and even Colorado will be in deep doo doo. There will NOT be enough water then to even minimally support the large populations that reside there now, let along provide water for business and industry so as to keep the local economies going.

Beautiful areas ... but basically a desert environment that is very dependent upon seasonal precipitation, precipitation that does not always occurs - per geological records.

It looks like 2 VERY BIG storms are headed to this watershed next week..I think it starts Monday?...I don't think this is over yet.

Desert people are going to desert. I won't feel sorry for them!

Something wrong with gauges-sensors.
