After multiple heavy thunderstorms in recent days, many rivers across the region are running at or above flood stage.
Hydrologist Mike Gillispie, at the National Weather Service, says efforts are being made upriver to minimize flooding in the Missouri River valley.
“The Corps of Engineers was able to cut back on releases from Gavins Point Dam ahead of a lot of this rain or as this rain fell,” Gillispie says. “That’s allowing the James, Vermillion and Big Sioux to drain out a little bit faster than if they were still releasing the 45,000 CFS (cubic feet per second) they had been doing there.”
Gillispie says some rivers and streams may take two weeks of fairly dry weather before they’re back below flood stage. He says the storms that brought us all of this rain are not typical for summer.
“This last week has just been really kind of a weird system that came through, or a couple of systems that came through, in that it was more of a springtime system,” he says, “but it had the warmth and the moist air to work with so it was a very efficient precipitation maker.”
The forecast calls for mostly hotter and drier weather for the next several days, which will help with flooded fields and roads.
