Matthew Meadows, Assistant Watermaster
Effective immediately today, June 7, 2023, the Army Corps of Engineers flood release targets from Pine Flat were reduced by 200 cfs. The new Pine Flat order is 11,800 cfs. Outflow from Pine Flat was reduced at 13:00 hours.
The target flood release in the North Fork below Crescent Weir will remain at 4,750 cfs. As of this morning, the target flood release in the South Fork was 425 cfs. The reduced target outflow will result in the South Fork flood target being reduced to zero. When the reduction arrives in 24-48 hours, South Fork flow will be for irrigation orders only. Irrigation demand on the South Fork is likely 200-230 cfs through the weekend, with daily changes as needed to maintain the minimum order at Pine Flat of 11,800 cfs. This morning South Fork flows consisted of flow below Army Weir and through Crescent Bypass. The Crescent Bypass was shut off this morning around 09:00 hours.
We are expecting irrigation demand to fluctuate in the short-term maintaining the target Pine Flat order, approximately 11,800-12,000 cfs through the weekend.
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.
