BISMARCK (AP) — The Army Corps of Engineers has begun lowering water releases from Garrison Dam in North Dakota earlier than planned.
Spokesman Clay Church tells The Bismarck Tribune that the corps wants to reduce pressure on Missouri River reservoirs downstream.
The corps on Monday began lowering Garrison releases from 150,000 cubic feet per second to 145,000 cfs. After July 9 releases will be slowly lowered to 120,000 cfs by July 18. The corps says inflows into Lake Sakakawea behind the dam are lower than previously forecast.
At Oahe Dam in South Dakota, releases will be rising slightly, though slower than planned because of the reduced flows from Garrison. Jody Farhat with the corps tells KCCR radio that the agency is trying to balance reservoir levels and releases in the upper basin.
