Due to increasing inflows into Jamestown Reservoir, the release has been increased to 450 cubic feet per second (cfs). Jamestown Reservoir is currently at pool elevation 1437.9 feet, which is 6.9 feet above the base of the flood pool, or 13 percent full.  Inflows are near 1,800 cfs.

Basin conditions and inflows to the reservoir will be continuously evaluated and adjustments to the releases will be made as needed. Another increase in release will likely be necessary in order to meet the flood pool evacuation target date of June 1. Jamestown Dam is owned and operated by the Bureau of Reclamation and releases from the flood pool are directed by the Army Corps of Engineers.

Pipestem Reservoir is currently at pool elevation 1458.8 feet, which is 16.3 feet above the base of the flood pool, or 16 percent full.  Inflows are currently near 280 cfs with a reservoir release of 0 cfs. The winter release out of Pipestem Reservoir was to benefit water quality for fish and wildlife and the release was shut down in response to the ice going out of the reservoir, which occurred on April 7. After Jamestown Reservoir’s flood pool is evacuated, Pipestem releases will be increased to evacuate flood storage by early September. Pipestem Dam is owned and operated by the Army Corps of Engineers.
