Jamestown Reservoir reduces releases

Published June 5, 2019

OMAHA, Neb. —Jamestown Reservoir in North Dakota has evacuated its flood control storage, and releases were reduced June 4, to 125 cubic feet per second, matching reservoir inflows.  Jamestown Dam is owned and operated by the U.S. Bureau of Reclamation and releases from the flood pool are directed by the U.S. Army Corps of Engineers.

Jamestown Reservoir is currently at a pool elevation of 1430.8 feet, approximately 0.2 feet below the base of the flood control pool. 

Pipestem Reservoir is currently at a pool of elevation 1470.7 feet which is approximately 35 percent full.  Inflows are currently near 10 cfs and releases are 0 cfs.  Releases have not yet been initiated from the reservoir in order to keep the lake at a steady-to-rising condition to promote successful crappie spawning conditions during the first two weeks of June.  Pipestem Reservoir releases will be increased in mid-June to evacuate flood storage by a target date of September 1, 2019.  Combined maximum releases out of Jamestown and Pipestem Reservoirs are not expected to exceed 750 cfs.  Pipestem Dam is owned and operated by the U.S. Army Corps of Engineers.

High river flows continue downstream of Jamestown into South Dakota on the James River, and conditions on the entire James River basin are considered in determining project releases.
