The Omaha District of the U.S. Army Corps of Engineers and the Bureau of Reclamation announced Tuesday that Jamestown Reservoir has reached its normal summer pool elevation of 1,431.3 feet. Pipestem Reservoir is 5 feet above the top of its conservation pool and is storing water to be released over June, July and August.
Releases from the Jamestown Dam dropped from 60 cubic feet per second to 12 cfs on Wednesday.
The decrease brings releases into line with standard winter operating procedures, according to Darrin Goetzfried, hydraulic engineer with the Bureau of Reclamation in Bismarck.
Local reservoirs continue to evacuate water as forecasted. Inflows continue to be higher than normal, but the reservoir pool levels are dropping at a rate of 0.7 feet per day at Pipestem Reservoir and 0.3 feet per day at Jamestown Reservoir.
The Oahe and Garrison reservoirs on the Missouri River in the Dakotas continue to rise.
The Army Corps of Engineers said Lake Oahe gained nearly 6 feet in March and is expected to rise another 3 feet this month. The reservoir is more than 10 feet higher than it was last year at this time.
The U.S. Army Corps of Engineers announced Tuesday the flood control storage has been nearly evacuated at Jamestown and Pipestem reservoirs and releases from the projects are approaching normal summer levels.
At 1 p.m., the releases at Jamestown Dam were decreased from 600 cubic feet per second to 400 cfs. With releases at Pipestem Dam remaining at 200 cfs, the total combined release from the two dams is at 600 cfs.
