Effective immediately, July 12, 2023, the Army Corps of Engineers flood release target from Pine Flat is being reduced by 1,000 cfs. Reductions will be made at two times: -500 cfs at noon and -500 cfs at 24:00 hours. This morning the Pine Flat order was 11,500 cfs. The decrease will make the order at Pine Flat approximately 10,500 cfs for a flood release target of 3,400 cfs at Crescent Weir. Outflow from Pine Flat might fluctuate based on irrigation demand, with anticipated releases of approximately 10,500 through Friday.
The target flood release in the South Fork Kings River remains at zero, only irrigation orders are being diverted into the South Fork at Army Weir.
Releases will continue to be adjusted accordingly to meet irrigation orders, local creeks entering below Pine Flat and changing conditions.
All data is provisional and subject to revision.
We will circulate updates as conditions change.
