sign that says Jefferson River


Formed in Twin Bridges by the confluence of the Big Hole, Beaverhead, and Ruby Rivers, the Jefferson flows northbound over eighty miles to the confluence of the Madison and Gallatin Rivers to form the Missouri. Receiving less pressure than any of the others, this is one of those fisheries that you have to see to believe.

What the Jefferson offers:

  • 80 miles of floatable water, with good wading opportunities.
  • Early stonefly hatches.
  • Great streamer fishing.
  • Unparalleled wildlife and scenery.
  • Larger than average trout.
  • Low angler pressure.
  • Did we mention BIG brown trout?
