The US Army Corps of Engineers is forecasting a less-than-normal runoff this year in the Missouri River basin above Sioux City.
Based on current soil moisture and snowpack conditions, the corps says the runoff is expected to be 80% of normal, or 19.9 million acre feet.
Runoff typically slows down in the winter months, however the corps says the warm weather we have experienced this winter has resulted in slightly above normal runoff in January.
Releases from Gavins Point Dam are scheduled to run at 14,000 cubic feet per second through the month of February. Releases will be stepped up in mid-March for the 2013 navigation season which opens April 1.
The corps says mountain snowpack is currently 96% of normal in the reach above Fort Peck and 89% in the reach between Fort Peck and Garrison. Typically, 64% of the peak mountain snowpack accumulation will have occurred by February 1.
