Omaha, NEB—Inflows to the Jamestown Reservoir are continue to increase due to snowmelt. As a result, reservoir releases have been increased to 500 cubic feet per second.
Jamestown Reservoir is currently at pool elevation 1437.8 feet which is approximately 13% full. Inflows are near 1,500 cfs. Basin conditions and inflows to the reservoir will be continuously evaluated and adjustments to the releases will be made as needed to evacuate the flood storage by the target date of June 1, 2019. 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 1466.8 feet which is approximately 28% full. Inflows are currently near 450 cfs with a low level water quality release of 10 cfs. Once ice cover is completely melted at the reservoir this water quality release will be shut down to 0 cfs. Pipestem Reservoir releases will be increased later in the year 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 Army Corps of Engineers.
High river flows continue downstream of Jamestown and into South Dakota on the James River, and conditions on the entire James River basin are considered in determining project releases.
