Winter Release Levels Decreased at Pipestem Dam

Published Jan. 22, 2020

  A river rise occurred late last week in the City of Jamestown due to ice formation south of town.  In order to provide relief, releases were reduced by 50 cfs from Pipestem Dam, for a total release of 200 cfs.  Combined releases from Jamestown and Pipestem Dams are now 650 cfs. 

Updated reservoir forecasts indicate the reservoirs will reach their target elevations by March 1.

The Corps of Engineers will operate to minimize the risk of ice-related flooding, and adjust releases as needed.

Jamestown Dam pool elevation is 1437.3 feet, 11% into the flood pool, and is dropping.  The pool elevation peaked on November 12, 2019 at 1442.0 feet, which was 31% into the flood pool.  Inflows are near 20 cfs, and releases are 450 cfs.

Pipestem Dam pool elevation is 1450.9 feet, 7% into the flood pool, and is dropping.  The pool elevation peaked on October 29, 2019 at 1475.0 feet, which was 43% into the flood pool.  Inflows are near 40 cfs, and releases are 200 cfs.

The Corps of Engineers is coordinating with relevant agencies in North and South Dakota.
