The Latest: Storm impacts Missouri River dam releases


March 15th, 2019 by Ric Hanson

The U.S. Army Corps of Engineers is increasing releases from a dam along the Missouri River in southeastern South Dakota as flooding escalates across the region due to a massive late-winter storm. The Corps says there is little storage capacity behind the Gavins Point Dam for runoff. That prompted the releases, which could worsen flooding downstream. But the agency says it’s helping with levee monitoring and other flood response measures.

Releases from the Fort Randall Dam upstream have been stopped to create more capacity behind Gavins Point. No releases from Fort Randall are expected for several days. The Corps also is working with the National Weather Service to monitor conditions. The weather service has issued flood warnings along the Missouri River and its tributaries from southeastern South Dakota to St. Louis in Missouri.
