BISMARCK – The U.S. Army Corps of Engineers (USACE) issued a contract announcement of more than $22 million to HSG Park Joint Venture 2, LLC for dredging of the spillway approach at Garrison Dam near Riverdale, U.S. Sen. John Hoeven, R-ND, announced. The work is expected to be completed by Aug. 27, 2027.

Built in 1953, the Garrison Dam is the second-most upstream project of six that were built on the mainstem of the upper Missouri River and has the largest reservoir storage capacity of all USACE projects in the nation. When combined with dams on the river’s tributaries, the projects reduce the risk of downstream flooding along the Missouri and Mississippi rivers.
