Madison River Fisheries

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.

We provide funding for conservation projects in the Madison drainage. Key projects include restoration of native westslope cutthroat trout in two tributary streams, aquatic habitat improvements in three tributaries, and extensive fish population monitoring.

Managing Water Temperatures in the Madison River

The Madison Thermal Decision Support System (DSS) was developed to manage water temperature downstream of Madison Dam to protect fisheries and other river resources. The goal of the DSS is to maintain maximum daily water temperature in the lower Madison River at or below 80 °F.
