Welcome to the Missouri-Madison Project 2188 Coordination Site.
NorthWestern Energy owns and operates two dams (Hebgen & Madison) on the Madison River and seven dams (Hauser, Holter, Black Eagle, Rainbow, Cochrane, Rainbow, & Morony) on the Missouri River. NorthWestern is authorized to operate all nine facilities by the Project 2188 license issued by The Federal Energy Regulatory Commission (FERC) in September 2000. The FERC license specifies conditions for operation and maintenance of the project including conditions to protect environmental resources.
The purpose of this site is to provide information on NorthWestern Energy’s ongoing resource stewardship programs implemented in the 525-mile river corridor from West Yellowstone to Fort Peck Reservoir.
We developed a water quality and biological monitoring program for the Missouri and Madison Rivers to identify long-term trends and to evaluate the effects of operation and maintenance of the hydroelectric facilities on these rivers.
NorthWestern Energy operates Hebgen and Madison dams on the Madison River and works diligently with individuals and agencies to protect, mitigate and enhance fisheries, wildlife, water quality and recreation in the Madison River drainage to offset any effects of dam operations.
