Gavins Point Dam Releases

With run-off expected to be above average this spring frozen soils throughout our region may lead to an increase in flooding for tributaries of the Missouri River reservoir system.

Kevin Low National Weather Service Hydrologist says tributary flooding may be seen in rivers and streams throughout eastern South Dakota and Nebraska.

Senior Hydrologist Joel Knofczynski says Gavins Point Dam releases have been reduced to about 20,000 cubic feet per second and are expected to remain there for the near future.

Runoff in the Sioux City reach of the Missouri River basin is expected to be above average over the next few months as the northern portions of the James River and Big Sioux River basins have widespread and moderate-to-heavy plains snowpacks.
