About The Madison River
The Madison runs out of Yellowstone National Park, through Quake Lake and the famed fifty-mile riffle water between Lyon Bridge and Ennis. It is one of the most consistent trout rivers in Montana because dam influence and broad insect diversity keep fish feeding through a wide range of spring conditions.
Most of the river's reputation is built on wild rainbow and brown trout, with strong dry-fly fishing when BWOs, caddis, and stoneflies line up. It is also a river where nymphing covers a lot of water efficiently, especially before the better surface windows show.
