Expect flow releases from Anderson Ranch Dam to begin to drop on Wednesday, September 3rd. Current flows of 1,850 cfs will drop to 1,000 cfs and will hold there until mid-September. After that they should drop again to 600. Then 300 in October.
WHEN WILL SOUTH FORK BOISE FLOWS DROP?
As of August 23rd flows from Anderson Ranch Dam are clipping along at 1,800 cfs. With a full Lucky Peak Reservoir and storage in Arrowrock still being drained, there’s a good chance that it will be time to throttle back on Anderson Ranch sometime around Labor Day.

NOT A NORMAL WATER YEAR ON THE SOUTH FORK
The flow regime in 2008 on the South Fork Boise departs from the standard practice of increasing flows to 1,600 cfs in late May and instead this year the flows have remained at 600 cfs through the month of June. As the upper graph shows, compared to last year and to “average” flow releases, we are well below flow levels even though snowpack is average. This is not normal. Why a difference?
