Construction Updates
The 125-mile transmission pipeline for the Red River Valley Water Supply Project is currently under construction. When it is complete, the buried pipeline will span from the McClusky Canal to the discharge structure, which empties into the Sheyenne River, located about six miles south of Cooperstown. The Missouri River intake pumping station wet well, intake screen structure, and tunnel are complete. The outfall discharge structure on the Sheyenne River is also already constructed.
