Communities on the lower Missouri River can expect water releases from the Gavins Point Dam to remain at twice the average level for the near future, the U.S. Army Corps of Engineers said.
May runoff in the upper Missouri River basin was 267 percent above average, which was second-highest on record. This will force the Corps of Engineers to maintain releases of 75,000 cubic feet per second at the Gavins Point Dam in South Dakota, which is more than twice the average release for this time of year.
“We will maintain Gavins Point releases at this rate to continue evacuating water from Oahe and Fort Randall, which have used much of their respective flood storage,” said John Remus, chief of the U.S. Army Corps of Engineers Missouri River Basin Water Management Division.
Oahe and Fort Randall dams are north of Gavins Point, on the Missouri River.
Cities and farms have suffered flooding on both sides of Missouri this year. In St. Joseph, the Missouri River was running at 26.7 feet Thursday. Its level was expected to fall to around 22 feet by the weekend.
The region remains under a flood warning.
