BISMARCK – The U.S. Army Corps of Engineers (USACE) has awarded a $23.8 million contract for dredging and placement of riprap protection as part of the Garrison Dam Spillway Rehabilitation project, U.S. Sen. John Hoeven announced Thursday. The project is estimated to be completed in April 2028.

“The Garrison Dam is crucial infrastructure in our region, and vital to ensuring that we have a reliable water supply for communities and agriculture, as well as recreation and tourism. At the same time, it’s a key component to controlling Missouri River water levels and protecting communities from flooding. This federal contract will help advance rehabilitation of the spillway, which is an important component to ensuring the dam’s long-term integrity,” Hoeven said.
