Recent rains in the upper basin of the James River have prompted officials to increase releases from Jamestown Dam from 200 cubic feet per second to 350 cfs, said the U.S. Army Corps of Engineers.

Releases from Pipestem Dam remain steady at 500 cfs for combined releases of 850 cfs flowing through Jamestown.

The upstream rain events caused water level behind the Jamestown Dam to rise to 1,431.9 feet above sea level. This is about 1 foot above the normal level of the reservoir.

The reservoir behind Pipestem Dam is at 1,461.7 feet above sea level. Releases of 500 cfs are planned to continue until Sept. 1 when the reservoir will be at its target elevation.

Heavy rains in the Elm River basin, a tributary to the James River in northern South Dakota, are also contributing to high flows in the South Dakota portion of the James River.

Officials with the Corps of Engineers will continue to monitor the levels and additional changes in releases are possible.
