Missouri River In Central South Dakota To See Little Impact From Flooding After Storm

(KCCR) — Massive flooding below Gavin’s Point Dam on the Missouri River should not impact the river in central South Dakota. A blizzard last week brought 10 inches of snow to Pierre with seven-point-five inches officially being tallied by the National Weather Service in Fort Pierre from the storm. Areas near Yankton received two-to-three inches of rain. The U-S Army Corps of Engineers had increased releases from Gavin’s Point to 100-thousand cubic feet-per-second for a time. Releases from Fort Randall Dam at Pickstown were shut down to nothing on Wednesday. John Remus, Chief of the Missouri River Basin Water Management office says slowing the releases from Fort Randall should not back up releases on the River…

“System-wide impacts of the zero discharges from Fort Randall Dam is minimal as the runoff in the upper basin has been slowed by colder temperatures. As of today we have 15 million acre-feet of the 13th or the 16.39 acre-feet of flood control storage. The mountain snowpack in the remaining plains snowpack that will drain into the system is nearly average, so we are in good shape to capture and manage that runoff while still having considerable ability to respond to downstream flood events.”
He says operations at the Oahe Dam should be unaffected by what’s happening downstream…

“Right now because we see fairly average snow pack in the upper Basin, we’re looking at pretty much average conditions, average operations on Lake Oahe and downstream through Gavin’s Point.”
As of Saturday , the Oahe Dam was taking in runoff at a rate 22-thousand c-f-s and discharging downstream 3,500 c-f-s. The Corps of Engineers says releases from Fort Randall are slowly being increased again.
