Matthew Meadows, Assistant Watermaster
The Army Corps of Engineers is increasing flood release targets starting Saturday, April 8, 2023, at 0400 hours from Pine Flat. The target in the South Fork will be increased from the current 2,000 cfs to 2,500 cfs in steps of 100 cfs per day for 5 days. The target flow will be routed through a combination of Army Wier and the Crescent By-pass. The target flow at Crescent Weir will remain at 4,750 cfs. The increases will take approximately 24-28 hours to move through the system to Army Wier. The order from Pine Flat is currently 10,500 cfs. Once this series of increases is made and any additional irrigation demand is incorporated, the release should exceed 11,000 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.
