Update: 

DAKOTA DUNES, S.D. (KTIV) – Community managers in Dakota Dunes, South Dakota, are preparing for rising river levels coming later this week.

On Friday, the National Weather Service revised its Big Sioux River Peak river stages at Sioux City from 27 feet to 30.2 feet.  While the Missouri River peak river stage was changed from 26.9 feet to 28.6 feet.

The NWS predicts the Big Sioux River to reach 30.2 feet sometime Tuesday or Wednesday and for the Missouri River to reach 28.6 feet sometime between Wednesday and Thursday.

Since the NWS projections were released the Army Corps of Engineers has announced they will reduce releases at Gavins Point Dam from 70,000 cfs to 60,000 cfs over the next five days.

Dakota Dunes managers say depending on the tributary flow, the reduction should have a minor impact on the short term peaks but no updates have been posted by the NWS as of now.

DAKOTA DUNES, S.D. (KTIV) – Community managers in Dakota Dunes, South Dakota, have their eyes on heavy rain that has fallen up north.

Dakota Dunes Community Improvement District Manager Jeff Dooley says the recent rains have caused the National Weather Service to project the Missouri River will rise to a level of 26.9 feet, at Sioux City, by Tuesday or Wednesday of next week.

The Army Corps of Engineers continues to maintain releases of 70,000 cubic feet per second from Gavins Point Dam, near Yankton, South Dakota.

Dooley says the Big Sioux River will also rise as a result of the heavy rain. The National Weather Service doesn’t have a projection for the Big Sioux River at Sioux City. But, earlier projections indicated a 27-foot river stage. That’s similar to levels last seen on May 29th of this year.

So, Dooley says Dakota Dunes will put a plan in place to plug and pump storm sewers similar to what the community has done for previous events.
