Oroville Dam's Spillway About to Collapse - Tallest Dam in the United States

https://www.rt.com/usa/377147-oroville-dam-collapse-evacuation/

The sheriff in Butte County, California has ordered an immediate evacuation of all people below the damaged Oroville dam, which is feared to be in danger of imminent collapse, Reuters reports.
“Immediate evacuation from the low levels of Oroville and areas downstream is ordered. This is NOT A Drill. This is NOT A Drill. This in NOT A Drill,” says the statement posted on the Butte County Sheriff’s Facebook page.

The statement refers to the Lake Oroville Dam, located 105 km (65 miles) north of Sacramento.

The dam’s spillway was “predicted to fail within the next hour,” the California Department of Water Resources (DWR) said at around 4:30pm PST Sunday (00:30 GMT Monday).

I hope those fursuits come with life preservers.

Keeping track of this elsewhere. The immediate crisis seems to have passed but apparently they need to repair shit before there's more rain - and more rain is forecast. Apparently they can't drain water through the powerhouse to carry out the repairs because debris from the broken spillways is clogging the outlets.

So yeah, you definitely want to make sure you are following pages which will issue alerts. There's likely to be flooding if not today then later in the week.

The Lake Oroville Dam Auxiliary Spillway structure has suffered potentially catastrophic damage as a result of erosion secondary to water flow. This damage could result in catastrophic failure of the Auxiliary Spillway. The California Department of Water Resources has increased exhaust water flow from the Gated Spillway to 100,000 cfs, in an attempt to decrease Lake Oroville water levels. This effort is an attempt to reduce flow from the Auxiliary Spillway. As an additional measure, helicopters will be depositing rock filled containers to strengthen the potential failure point. This development caused the Butte County Sheriff, Kory L. Honea, to order the mandatory evacuation of the City of Oroville, south to the Sutter County Line. Residents are advised to evacuate to one of the shelters listed below. The Sheriff, in an effort to safe guard residents of Butte County, had no choice but to make the decision to require this mandatory order. CAL FIRE Incident Management Team #3 is now in Unified Command with Butte County Sheriff and the Department of Water Resources on managing the incident.

Oroville is an area that is mostly White and voted mostly Trump though...

However that's beside the point.

The dam is fine. The emergency spillway, which is separate from the main dam and spillway, is what they're saying is expected to fail. In that event, you would be looking at 30 ft of depth of the lake headed down the river. The river is already running at capacity, so any further increase of level would lead to it overrunning its banks into the communities beyond.

DWR officials are saying that erosion of the emergency spillway was not as severe as they projected. And that the level of Lake Oroville has been reduced to below the level of the spillway. To reduce the level, 100,000 cubic feet per second (cfs) of water was released for several hours.

However, A new storm is supposed to hit the area on Wednesday. It's supposed to continue raining for maybe a week. This is far from the end of this. If the temperature rises quickly at the end of that storm, the level of the lake plus the increased snow melt being fed into the reservoir is going to create the same hazards. By the end of the week or the middle of next week, things could be pretty grim.

So hope for the best for the people of Oroville, because a lot of people may be losing their communities.
 
It would be interesting to see how much of the money for upkeep of the dam was squirrelled away, because drooouuuuught and droughts never end so they'd never need that spillway, and blown on useless administrative salaries.

If this happened, no one will ever look into it.
