OMAHA -- Runoff into the Missouri River basin in 2018 is forecast to be above average, according to the U.S. Army Corps of Engineers.
Runoff is forecast at 29 million acre feet, 115 percent of normal.
"The updated forecast increased from last month due to the continued accumulation of mountain and plains snowpack in the upper basin," John Remus, chief of the Missouri River Basin Water Management Division, said in a news release.
As of March 1, mountain snowpack was 129 percent of average in the reach above Fort Peck Dam in Montana and 134 percent of average in the reach from Fort Peck to Garrison Dam in North Dakota.
Storage in the six Missouri River reservoirs currently totals 56.4 MAF, occupying 0.3 MAF of the 16.3 MAF flood control zone. Releases from Gavins Point Dam near Yankton, South Dakota, have been increased to 20,000 cubic feet per second.
Beginning about March 19, Gavins Point releases will be increased 3,000 cfs per day until reaching 26,000-28,000 cfs to provide flow support for Missouri River navigation downstream.
