The Oroville Dam is the highest in the nation.
What I wanna know is where are all those missing 16” concrete slabs that went walkabout ?
Thanks!
Look at that pile of crap in the river!
I reckon those missing slabs are down in that new canyon to the right . . .
Northern California will face a new flood crisis for Oroville Dam and Shasta Dam, as 10 days of up to 75 degree weather will spark an early spring snowmelt.
With the National Oceanic and Atmospheric Administration (NOAA) rating over 90 percent of California as experiencing an “Extreme Water Year,” the media are welcoming sunny skies that are expected to spike Northern California valley temperatures to 75 degrees or higher.
Because hundreds of smaller dams in Northern California have been allowed to fill, water runoff for the Sacramento Valley from Sierra Nevada-fed rivers is running at 130 percent of average for this time of year; versus rivers flowing into the San Joaquin Valley, which are running at 190 percent of average runoff.

Hi KC Burke,
Yes, there was an event that went for 40+ days of rain & 10 to 15 ft of snow up in the mountains that combined to yield a “megaflood”.
Scientists have released research publications on this phenomenon and they dubbed it “ARkStorm” (play on the wording of Noah’s Ark).

Below is an excerpt as the doc is sizable (download).
Notice the 2nd paragraph in the excerpt.... Then think of the current situation. There is more than 10 to 15 ft of snowpack. The recent wave after wave of “atmospheric rivers” inundating California... hmmm sounds like the same lurking scenario of water volumes.
Oroville Dam Specifications’ hydrological flow references, regarding floods, are in the upper right corner. I believe the larger numbers of “standard project flood” to “Spillway design flood” were intended to handle the worst case scenario encountered in the winter of Dec 1861-Jan 1862 - even if these cfs flow numbers are not present (they may have estimated that megaflood cfs flow for the Feather River basin).
== excerpt:
The hypothetical storm depicted here would strike the U.S. West Coast and be similar to the intense California winter storms of 1861 and 1862 that left the central valley of California impassible. The storm is estimated to produce precipitation that in many places exceeds levels only experienced on average once every 500 to 1,000 years.
Extensive flooding results. In many cases flooding overwhelms the state’s flood-protection system, which is typically designed to resist 100- to 200-year runoffs. The Central Valley experiences hypothetical flooding 300 miles long and 20 or more miles wide.

My understanding it that the Global Warming / Climate Change crowd in CA does not want to see an advancement in California water storage. Instead, they want NIMBY standards to force “others” out and forced water control and population limitation to reduce usage. There is no leftist interest in “solving” the water supply shortage.
The technology and understanding we now have was not available between the 1920s and 1975 when all of the current storage was built. Oroville is not something to survive and to try not to repeat, it is instead, the first episode of a long dramatic mini-series that will have episode after episode for year after year. Days of Our Lives coming to a stream bed near you.
You rock!
That took me like a dozen attempts...
what a pain in the you-know-what...
According to reports, they will begin to shut off the flow tomorrow morning.
I hope we get some more images during the day.
Yes it is a pain.
It will be very interesting to see the damage once the water is shutoff.
That is the best picture yet of Oroville dam, Feather River, the damaged spillway and the barges. Has there been confirmation that the dam’s generators are damaged or what it will take to begin generating electricity? Or is it still a dangerous situation, e.g., when the snows melt in spring?
As far as we know, the equipment in the hydro plant is OK...
News has been sparse.
Snow melt remains an unknown factor.
Thank you for posting this!
So it’ll be a squeaker. I wonder the impact on electrical grid come summer if the dam isn’t generating? Wish they’d not deactivated the nuclear plants.
