2011 Missouri River Flooding Update #8

Here is the latest on the long lasting Missouri River flooding. As yet, they have NOT begun the draw down at Gavins Point Dam west of Yankton SD. This is mainly due to continued inflow into the reservoir. Because of this and the heavy rain that fell in the river valley last evening, the river will remain above flood stage at least through Labor Day Weekend.

At Sioux City the stage was 32.95ft at 7pm this evening. Flood Stage is 30 feet.

The river could fall below flood stage by the following weekend barring any delays in the release and or heavy rainfall.
