Increased releases at the Oahe Dam have caused the Missouri River to rise about two feet during the last two days. And as those increased releases continue the problems are trickling down to the southeast part of the state.
The Army Corps of Engineers started constructing a backup levee on Sunday to protect the town of Dakota Dunes.
The 1.4 mile levee in Dakota Dunes is expected to be complete by Thursday. The Corps increased releases by another 10,000 cubic feet per second on Sunday.
The current flow is now at 130-thousand cubic feet per second.
