OMAHA | Water releases from Gavins Point Dam will remain high during November as the U.S. Army Corps of Engineers continues to evacuate excess water from the Missouri River's mainstream reservoirs.

Releases will remain near 31,000 cubic feet per second for the first half of November before increasing to 32,000 cfs. Releases from the dam near Yankton, South Dakota, will remain at that level until late November, when they will be reduced by 3,000 cfs per day until reaching the winter release rate of at least 17,000 cfs. Winter releases typically range from 12,000 cfs to 17,000 cfs.

Above normal runoff during the late summer and fall is leading the higher November releases, said John Remus, chief of the Corps of Engineers' Missouri River Basin Water Management Division. A total of 2.1 million acre-feet of water is still being held in the system's flood control storage zone. That water will be released during the fall and winter so that the river's reservoirs will have the normal 16.3 MAF of flood control storage capacity when next year's runoff season begins.
