High water on Missouri River delaying inspections, maintenance

YANKTON, S.D. (WNAX) – Continued high water on the Missouri River is pushing back inspections and maintenance of flood control projects.

Tom Curran, Operations Manager at Gavins Point Dam near Yankton, says they are waiting to do an inspection of the spillway gates.

A dam on the Niobrara River in Nebraska failed in March, which caused a flood surge into Lewis & Clark Lake.

Spillway gates at Gavins Point Dam had to be raised to push the lake to a record height to contain the flooding.

Curran says that put more stress on the dam.

Curran says operations have been pretty normal since that flooding.

Releases are currently at 70,000 cubic feet per second and are expected to stay at that level well into November.
