Corp to increase water released from Garrison Dam
Posted on 3/28/2009
Bismarck, ND - The North Dakota Department of Emergency Services (NDDES) requested the United States Army Corps of Engineers to release 9,000 cubic feet per second (CFS) of water to continue to ensure water supplies are adequate.
This decision was made in consultation with North Dakota State Water Commission engineers. It is not anticipated this release will have a significant impact on ice jams in our area. The North Dakota State Water Commission has personnel regularly monitoring the ice jams and water levels on the Missouri River. These releases may cause river levels in the Bismarck/Mandan area to stabilize or rise slightly tomorrow.
Water releases from the dam before the Bismarck/Mandan flood event were 11,000 CFS. These releases combined with Heart and Knife River inflow resulted in flows of approximately 70,000 CFS. The current combined flows are now less than 20,000 CFS.
With water levels in south Bismarck receding, it is important to restore water supplies along the river to ensure adequate water supply for public use. This increase in flow also enables area power plants to produce power.
