Three Week Forecast May 22
Precipitation totaling between 2 to 5 inches, fell over central Nebraska and much of South Dakota over the last 2 to 5 days. Because of the rain, inflows into Oahe, Big Bend, Fort Randall, and Gavins Point Dams have been increasing and causing pool levels to rise. The forecast rise at Oahe Dam and Fort Randall Dam includes storing runoff in their exclusive flood control pools. Releases from Gavins Point Dam will allow more water to pass through the system and slow the rise in the pool levels at these projects.
