Effective immediately, June 28, 2023, the Army Corps of Engineers flood release target from Pine Flat is being increase by 750 cfs today. Increases will be made at the following times: 400 cfs at 13:00 hours and 350 cfs 24:00 hours. This morning the Pine Flat order was 9,525 cfs. The increase will make the order at Pine Flat approximately 10,300 cfs for a flood release target of 3,400 cfs at Crescent Weir. Outflow from Pine Flat will fluctuate based on irrigation demand, with anticipated releases between 10,200 to 10,400 cfs through the weekend.
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. The flood release target in the North Fork below Crescent Weir will be adjusted as the changes at Pine Flat occur. As of this morning, the target flood release in the North Fork was 2,650 cfs.
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.
