Both changes will occur around 24:00 hours. This morning the Pine Flat order was ~9,850 cfs. By Sunday, June 25, 2023, the order at Pine Flat will be approximately 9,050 cfs for a flood release target of 2,150 cfs at Crescent Weir. Outflow from Pine Flat will fluctuate based on irrigation demand, with anticipated releases between 8,900 to 9,100 cfs on Sunday and Monday.
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 reduced as the changes at Pine Flat occur. As of this morning, the target flood release in the North Fork was 2,950 cfs.
Releases will continue to be adjusted accordingly to meet irrigation orders, local creeks entering below Pine Flat and changing conditions.
