The graph is probably correct, however the "normal" or Multi-purpose Pool (MPP) is 867.0, so a lot of that early in the year sharp drop was flood water evacuation from the late December 2015 flood.  Yes I believe there is a level below which SWPA is required to stop generating, but I honestly don't know what it is.   The amount of water Springfield pumps from Stockton lake seems like a lot but when you consider that the top 12 inches of Stockton consists of roughly 8 Billion gallons of water, it really doesn't amount to much.  I can't remember what the amount of water Springfield is allowed to pump, but if they pumped 30 million gallons a day it would take 271 days to get that top 12 inches of water.  In comparison at full capacity generation it would take maybe 3 days.  that is not throwing in any variables etc. just some quick generalized calculations.  TR is currently in the same "boat" for low levels due to generation, as is Harry S. Truman.

A friend of mine used to work for Spfld City Utilities.  He told me it was 1 million gallons per day when in full swing.  Evaporation is probably more than that.

The reason they will not generate this weekend is do to the flood watch that has been issued. They don't generate in potential flood situations as it can make flooding downstream of the dam very severe.

Straw hat is correct, when flooding is an issue dams shut down.  Unless there is a lot more rain somewhere than around my home I don't see flooding being a problem.  I had 2.5 inches in the rain gauge and the creeks didn't even come up much that I can tell, a little muddy but didn't see much run off.  The very first of the rain here yesterday morning was hard and heavy, but since then it was great soaking in rain.  Dry soil and vegetation do a wonderful job of slowing it down and letting it soak in.  There may have been a lot more in other places though.

My 2 cents.

I think it is due to all the airconditioners working during the heat advisories and warning this and last month.

In Stockton Lake history, it was not possible to run both generators at the same time without causing flooding downstream.  Is that still the case?

Take advantage of what is visible now for the future at normal levels.B)

A good friend of mine was in charge of the pipeline construction. He told me that all CU had to do was put in bigger pumps to double the amount of water they could move. Pipes are bigger than are needed for the amount they're suppose to draw.
