Oahe Inflows Continue To Increase As Warmer Weather Speeds Up Snowmelt

(WNAX) — The Corps of Engineers is attempting to balance the reservoirs on the Missouri River as snowmelt picks up.  John Remus, Chief of the Water Management Division in Omaha, says inflows to Lake Oahe have increased considerably…

“Over the last 24 hours at Oahe the inflows have average 98,000 cubic feet per second which is an increase of 20,000 cubic feet per second from yesterday Oahe releases have averaged 3,500 cubic feet per second and the pool has risen about point-5 feet.”

Remus says the flows into Lewis & Clark Lake have also been consistently high…

“Over the last 24 hours, inflows into Gavin’s Point Dam have averaged 23,000 cubic feet per second primarily from the Niobrara River. A reconnaissance of the lower Niobrara River indicated that there is a lot of water stored in the floodplain of the Niobrara River. Furthermore the remaining snowpack in the upper portion of the Niobrara River basin is beginning to melt and we are seeing the flow at the gauges on the Niobrara River.”

Remus says they have to change the releases from Gavins Point Dam…

“We have changed our plan releases from Gavin’s Point Dam. We increased releases to 27,000 cubic feet per second this morning and plan to make 3000 cubic feet per second increases Wednesday and Thursday. This will allow us to increase releases from Fort Randall Dam. Additional system releases are likely as there is still considerable plains snow melt yet to come. We will continue to evaluate the conditions and make adjustments as necessary.”

Remus says they are watching the snowmelt along rivers and streams that feed into the Missouri River above Ft Randall Dam and may have to make other adjustments.
