The Madison River Foundation is a non-profit membership organization founded in 2003 based in Ennis, Montana.

From a local endeavor with an emphasis on fly fishing, the Madison River Foundation has extended its vision to include consideration for initiatives from the headwaters of the Madison in Yellowstone National Park to the Three Forks of the Missouri.

The Madison River Foundation is perfectly positioned to be a primary source of local support for projects or initiatives that might benefit the Madison River watershed. This position will be further leveraged by developing cooperative relationships with various governmental agencies and other conservation groups to pool resources and enter into joint endeavors.
