CorpsEngLogoTHUMBOmaha (CSi) The US Army Corps of Engineers will increase in water release at the Jamestown Reservoir, on Wednesday May 21, 2014.

At that time the Jamestown Reservoir release will be increased to 500 cfs.

The Pipestem Reservoir release will remain unchanged at 5 cfs.

The change will increase the James River level by about 4 inches at the Jamestown gauge.

Pipestem Reservoir is currently at pool elevation 1459.1 feet which results in 17 percent of the flood pool occupied. Inflows are currently 160 cfs with a reservoir release of 5 cfs. Jamestown Reservoir is currently at pool elevation 1433.4 feet which results in 3.2 percent of the flood pool occupied. Inflows are currently 400 cfs with a reservoir release of 445 cfs. The combined release is 450 cfs.

This release increase is necessary to speed the evacuation of the Jamestown Reservoir flood storage and draw the lake down to the normal summer elevation of 1431 feet. The combined release of 505 cfs is expected to continue until the Jamestown Reservoir flood storage is evacuated on or near June 1. Pipestem Reservoir flood storage will be primarily evacuated in June, July and August with a release of around 200 cfs. All flows may change depending on rain over the summer.
