OMAHA, Nebraska -- The U.S. Army Corps of Engineers is increasing releases from Jamestown and Pipestem Dams to a total combined release of 2,400 cubic feet per second (cfs) by Saturday, October 26. Releases will be slowly increased to allow for monitoring of downstream channel conditions. The table below details the release schedule.

The cities of Jamestown and LaMoure are making the necessary preparations for this increase, and downstream channel capacity through Jamestown will continue to be closely monitored.
Jamestown Dam is currently at pool elevation 1434.9 feet, almost 4 feet above the base of the flood control zone, and rising. Inflow into the reservoir is near 1,400 cfs and the release is 1,000 cfs.
Pipestem Dam is currently at pool elevation 1461.3 feet, almost 19 feet above the base of the flood control zone, and rising. Inflow into the reservoir near 1,700 cfs and the release is 800 cfs. Upstream gages in the basin continue to rise as snowmelt runoff reaches the river.
Releases are being increased with the goal of evacuating the flood control storage from Pipestem and Jamestown reservoirs before winter. Basin conditions are being continuously evaluated and adjustments to the releases will be made as needed. 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.
The Corps of Engineers is coordinating with the Bureau of Reclamation and the cities of Jamestown and LaMoure.
