Officials will begin to reduce releases from Jamestown and Pipestem dams Thursday, Nov. 7, in anticipation of ice forming on the James River, according to the U.S. Army Corps of Engineers.
Releases are currently at 1,200 cubic feet per second from each dam for a combined 2,400 cfs. Releases will be reduced by 100 cfs each day from each dam until combined releases reach 800 cfs on Nov. 14.
The plan is tentative and will be adjusted for weather and ice conditions. River ice forecasts will be continuously updated during this time. If conditions change and the forecast ice-in date shifts, combined releases will be held at 1,400 cfs until three days before the new ice-in date.
Once ice forms on the James River, releases will be held at no more than 850 cfs until the reservoirs reach the normal winter pool elevation. However, additional precipitation, earlier than expected ice formation on the river, or higher than expected baseflow, could necessitate higher release levels.
