The U.S. Army Corps of Engineers today made it official today: Garrison Dam water releases will increase to 60,000 cfs by Friday.
In a statement issued this morning, the Corps’ Missouri River Basin Water Management Division said releases will be stepped up from 52,000 cfs to 60,000 cfs over the next three days.
The Garrison reservoir is currently at 1851.6 feet. It is expected to peak near 1852.4 feet in the next two weeks as runoff from the remaining mountain snow pack tapers off.
The 60,000 cfs release rate is expected to continue into mid-July.
The increased release means the river stage near Bismarck will rise from 11.5 feet to 13 feet.
Flood stage at Bismarck is 14.5 feet.
Garrison releases are being increased due to recent rains in the area from Fort Peck to Garrison.
“Widespread rains across much of the Missouri River Basin have increased inflows into the System dams and have also increased flows on tributaries downstream of the System,” said John Remus, Chief of the Missouri River Basin Water Management Division.
