About this float trip

The Madison between Quake Lake and Ennis is known as the fifty-mile riffle, a continuous braided run of pocket water with no real pools and almost no flat water. It is one of the most heavily fished rivers in Montana and still fishes well, because the habitat is that good. Wade fishing is the norm on the upper reaches, and floating is how you cover water between accesses. Note that a section of the upper river is restricted to wade fishing only.

Float the famous "50-mile riffle" from Three Dollar Bridge down past McAtee toward Ennis.

Highlights

What earns the trip

  • The fifty-mile riffle, continuous holding water rather than pool and drop
  • Salmonfly hatch in late June and early July is the event of the season
  • Wild browns and rainbows for the entire length
  • Fishing access sites are spaced closely enough to pick almost any float length

Before you go

Know before you go

  • Parts of the upper Madison are closed to fishing from a boat. Check the current Montana regulations for the section you plan to float.
  • Wind funnels down this valley most afternoons and makes rowing work.
  • Montana requires a nonresident fishing license and, on some waters, an AIS prevention pass.
