Release Plans Announced for Pipestem Reservoir

Published June 16, 2017

Pipestem Dam releases have begun in order to evacuate flood storage as outlined in the water control manual.  Releases are currently set at 125 cubic feet per second (cfs). Jamestown Dam releases are set to match the inflow of the reservoir and are currently 75 cfs. The combined release will be 200 cfs.

Pipestem Dam is currently at pool elevation 1463.68 ft, which results in 23.0 percent of the flood pool occupied.  Inflows are 258 cfs.  Jamestown Reservoir is currently at pool elevation 1430.9 ft, at the base of the flood pool.  Inflows are 77 cfs. Throughout the summer Jamestown Dam releases will be adjusted to match the inflow in order to maintain the summer target pool elevation.

Pipestem Dam releases will be set at 125 cubic feet per second (cfs) for the next two weeks, then increased to 250 cfs on July 1. In mid-July, the release will then be adjusted in order to evacuate the flood pool and reach the September 1 target elevation of 1442.5 ft. This release schedule was set in order to facilitate ideal spawning conditions for the crappie fish population within the reservoir.  The combined release will vary over the summer as both Pipestem Dam and Jamestown Dam releases are adjusted.  All releases may change depending on rain.
