Jamestown (USACE) The U.S. Army Corps of Engineers, Omaha District announces that at Jamestown and Pipestem Dams, the maximum combined releases are not expected to exceed 200 cubic feet per second this year. Significant rainfall could necessitate higher release levels.
On Thursday, Pipestem Reservoir was at pool elevation 1440.4 feet, 2.1 feet below the base of the exclusive flood control zone, with approximately 11 cfs inflow and a water quality release of about 11 cfs. Jamestown Reservoir was at pool elevation 1429.9 feet, 1.1 feet below the base of the exclusive flood control zone, with negligible inflow and no release. All the flood storage at Jamestown and Pipestem Reservoirs is currently available.
Forecasts for the 2021 calendar year indicate less than 40,000 acre-feet is expected to flow past the Jamestown, North Dakota streamgage. This would make 2021 a low flow year, again with expected maximum combined releases of no more than 200 cfs. Significant rainfall could result in higher release levels.
Current conditions in the basin are dry with almost the entire James River basin in moderate to severe drought conditions. Soil moisture conditions are below normal. Winter snowpack was below average, and no significant runoff due to snow occurred into the reservoirs this year.
