river in southwestern Montana and northwestern Wyoming, U.S. The Madison River rises in the northwestern corner of Yellowstone National Park at the junction of the Gibbon and Firehole rivers. It flows west through Hebgen Lake (impounded by a dam) into southwestern Montana, then turns north between the Madison Range and Tobacco Root Mountains to flow through Ennis Lake, which was created by Madison Dam. After a course of 183 miles (294 km), the Madison joins the Gallatin and Jefferson rivers just northeast of Three Forks to form the Missouri River.
