USACE conducting dam safety modification study efforts at Garrison Dam in North Dakota

OMAHA, Neb. -- The U.S. Army Corps of Engineers, Omaha District is conducting a dam safety modification study at Garrison Dam, near Riverdale, North Dakota. The study addresses risks associated with the design of the concrete spillway. These risks were identified during the 2011 Missouri River flood, when the Garrison Dam’s spillway was used for the first time in the dam’s nearly 70 year history to help control the flow of the Missouri River and lessen the impacts of severe flooding on downstream communities like Bismarck.
