Matthew Meadows, Assistant Watermaster
Effective immediately, June 2, 2023, the flood release targets from Pine Flat are being reduced by 200 cfs. Currently Pine Flat order is 12,400 cfs will be reduced to 12,200 cfs. This reduction at Pine Flat will be made in two changes, -100 cfs this afternoon, and -100 cfs tomorrow morning. The total outflow at Pine Flat might fluctuate with irrigation orders.
The target flood release in the North Fork below Crescent Weir will remain at 4,750 cfs. The current target flood release in the South Fork is ~850 cfs and the change at Pine Flat will reduce this target to approximately 650 cfs. The changes to the South Fork target take 24-48 hours to arrive at the Army Weir from Pine Flat. Changes in the South Fork target will be made daily to as needed to maintain the minimum order at Pine Flat. Current South Fork flows consist of flow below Army Weir and through Crescent Bypass. The balance of flows at those locations will be made over the next few days.
We are expecting irrigation demand to fluctuate in the short-term maintaining the target Pine Flat order, approximately 12,200-12,300 cfs, until further notice.
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.
