The Oroville Dam is the highest in the nation.
Dumb question.. why are they cutting power lines?
Apparently to get the lines out of the way for some heavy equipment to conduct planned repairs

The Wx radar looked like there was a break between successive bands of rain, so maybe so.
Typo ?
Hard to imagine a 20k reduction in an hour.
Not sure.
Check the pics in post 1216. Is the tower in jeopardy?
There are also cutting back outflow to 75,000
It’s related to real time rainfall, but it’s also related to water releases upstream. I’m with TVA - we have a river system and there is a timing factor to releasing water upstream and when it arrives at the next dam down the river. For example (and this is purely hypothetical, since I don’t have raw numbers in front of me), if TVA releases 100,000 cubic feet from, say, Guntersville Dam, it will be maybe 3 or 4 hours before that increased flow reaches the next dam downstream.
So in this case, they may have released water hours ago and that water got to Oroville and has since backed off because that particular volume of release has terminated. The number will go up and down, but on average, will be higher through and after the rain period.

Spill coming out of main spillway.
Ask for extra vigilance in monitoring.
The maps I'm seeing aren't showing any .. are there any dams upstream of Oroville that would be affecting its reservoir level ?
(disclaimer: i'm in PA and unfamiliar with CA other than being glad i'm not out there ;-)
Is that bottom photo today?
WTH??
Is that in prep for cutting power?

Yup... there was a pause a few hours ago... not sure of the lag between rain and inflow though.
Maggie, that new flow of muddy water isn’t
cheering me up.
Now Sean is back live from Oroville.
What is the brown stream of water down the side of hill to left of the spillway coming from??? Any commentary mentioning that?

It has been in the upper 20,000 to mid 30,000 range. I think I saw 18,000 yesterday. 14 seems low, given the rain situation. But it could be a bad reading too.
all of those trenches they filled below the emergency spillway are going to now erode DEEPER on each side of the rock piles they put in place. I don’t know why they shut the water flow thru the turbines as well... they should have left some water flowing thru them if not fully open.
