The Army Corps of Engineers is increasing flood targets Thursday, March 30, 2023, at 0400 hours. The target in the South Fork at Army Weir will be increasing from 1,600 cfs to 1,700 cfs. Additionally, on Friday, March 31, 2023, the target into the South Fork at Army Weir will be increasing from 1,700 cfs to 1,800 cfs. The target flow at Crescent Weir will remain at 4,750 cfs.
The release needed to meet that target will be released from Pine Flat at 0400 hours on Thursday and Friday. The increase will take approximately 24-28 hours to move through the system. This will result in orders from Pine Flat being in the 9,300-9,600 cfs range.
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.
