OMAHA, Neb. - The latest runoff forecast for the Missouri River Basin above Sioux City, Iowa, is showing signs of improvement.
The forecast currently shows that recent rainfall, increased mountain snowpack and late-season plains snow has provided improved runoff conditions.
The latest forecast shows the river is about three percent above average. The forecast is based on soil moisture conditions, several snowpacks, and long-term precipitation and temperature outlooks.
Beginning in mid-March, releases from Gavins Point Dam were adjusted to provide flow support for Missouri River navigation.
Navigation flow support for the Missouri River is at minimum service for the first half of the year, which began April 1 at the mouth of the river near St. Louis.
