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.
I agree.
While the inflow vs. outflow are interesting to know,
the important number is the lake level.

They are maintaining the goal of 50 feet below the emergency spillway.
Another item of interest. Since this morning the 24 hour rainfall measurements in the Oroville basin are starting now to look like the production of 7 to 10.
Last 24 hours the Gauges are as follows:
Brush Creek 3.47
Strawberry Valley 4.79
Four Trees 4.79
Bucks Creek 2.92
Bucks Lake 5.39
La Porte 5.59
Quincy 3.80
Grizzly Ridge 3.89
These figures don’t include rainfall prior to 7:00 last night as they are 24 hour totals not storm totals.
