The IFR below Redinger Lake appears incorrect: image

From license:

During operation of the facilities authorized by this license, the Licensee shall maintain the San Joaquin River at the following continuous, minimum flows as measured at the gage locations indicated: San Joaquin River below Dam No. 7 - Gage at Station 11242000; From October 1 to April 1 of Dry or Critically Dry Water Years for the San Joaquin Basin (as forecast on April 1 by the California Department of Water Resources (DWR) each year, with the reduced flow period beginning the following October): 15 cubic feet per second (cfs), provided the combined flow of the San Joaquin River and Willow Creek is maintained at 20 cfs (as measured by the combined flows at gages 11242000 and 11246500) All other times: 20 cfs

Current IFR is 3.0 cfs

I have modified the IFR to a fixed 32 cfs, based on recent (post-2006) observations:

Based on the above generally good match between observed and simulated for the later period (which does not seem to correspond with the license, but does correspond with the time period of the 2006 Settlement Agreement, though it's unclear exactly the relationship between this and the SA), I'm going to now close this issue.
