Releases increasing from Jamestown Dam

Published Oct. 4, 2019

OMAHA, Neb.— The U.S. Army Corps of Engineers is increasing releases from Jamestown (N.D.) Dam today  to 500 cubic feet per second, and will be increased to 600 cfs this weekend. Pipestem Dam will continue to release 600 cfs, for a total combined release of 1,200 cfs by Monday.

Increased river flows and the resulting higher than forecasted runoff necessitated the increases.

Pipestem Reservoir is currently at pool elevation 1459.1 feet, more than 16 feet above the base of the flood control zone, and rising. The inflow is near 800 cfs. Jamestown Reservoir is currently at pool elevation 1431.9 feet, almost one foot above the base of the flood control zone, and rising. The inflow is near 550 cfs.  Basin conditions will be continuously evaluated and adjustments to the releases will be made as needed. The target date for evacuation of flood control storage from Pipestem and Jamestown reservoirs is November 1.

The Corps of Engineers is coordinating with the Bureau of Reclamation and the City of Jamestown. Combined releases could increase if basin conditions warrant.


Release no. 19-115
