there seems to be alot more water going down what is left of the good portion then even this morning in Reed timers video
the release has been constant
the water force must have moved something that changed the direction of some of the flow?
Could be clearing MS gates clogged with debris??
Yesterday crews were clearing 2, 3 and 6 of 8 gates.
Since you first posted a link to this guy I’ve been watching him.
Every news reporter in the country could learn from watching him. He’s telling the story. Reporting whats he’s learned and he’s interested in it.
He is terrific!

Speaking as someone involved in agriculture; will be interesting to hear the impact on California agriculture.
Hard to see that it wont be a big impact for some.
However the rainy season should be ending soon. Having lived there; that is my recollection it ends in mid March normally.
That’s a big difference isn’t it?
My ignorance is showing here, but the piece you posted upthread states all the feeder lakes are full too. Are any of those going into Oroville, I wonder..
Exactly. Agriculture is big business up and down the state. The melting of spring snow will impact the streams, dams, rivers and levees.
Those feeder lakes all go into Oroville, and they’re “filled to the brink”.
Almanor, which holds 1/3 of Oroville capacity, has no data posted for the last 10 days.

They've built up a cushion of space in the reservoir. They can sustain many hours of inflows in excess of outflows. I think that they're paying particularly close attention to this lake level now.

California I believe; has the bigest ag economy in the nation
With rainy season and snow melt this issue will go on for months.
The lake level is now the very same as it was when they turned off the flow before and pushed the water over the emergency spillway.
...Hope they’re not gonna tickle my ‘irony bone’!

Close to disaster.

Excuse me maggie while I use a reply to you to post a general comment.
Everyone should realize that the Outflow is measured by the gate opening settings and flow meters to determine the approximate amount of outflow. The Inflow is much less precise. I understand that it is determined from lake level and Outflow being compared. The lake size at a given lake elevation is know and the acre feet can be calculated for each tenth of a foot the lake goes up and down. Therefore, the two thing that they need to control are adjusted based upon what they see mathematically coming into the lake.
The two things they need to control are lake level to control risk versus capacity and the impact of their outlet waters downstream with whatever the rivers empty into the bay. Tide levels in the bay play a roll. Rain and river gauges play and role and storms that aren’t even flowing into the Oroville drainage play a role.
They have decided they will shoot for a certain capacity and are holding that target lake level as best they can without too severe flooding downstream. I think we are seeing Shasta cut its flow more severely as they have more headroom.
