Beginning Monday, the release from Gavins Point Dam will be reduced from 160,000 cubic feet per second to 150,000 cfs. Gavins Point Dam is the last in the series of dams and closest to Omaha. It will remain at that rate until approximately August 16. At that point, the flow will be stepped down 5,000 cfs daily until it reaches about 90,000 around August 27.
The Gavins Point Dam release will stay at 90,000 cfs about two weeks then drop 5,000 cfs every two days until it reaches 40,000 cfs around September 30. A release of 40,000 cfs is slightly above the typical release rate in the fall.
The Corps expects the Missouri River to be back in its banks in Omaha by mid September. Sioux City is forecast to be below flood stage near the end of August.
The Corps says 2011 turned out to be the highest runoff season its 113 years of record keeping in the Missouri River Basin.
