Jefferson

Jefferson River fly fishing

Beautiful scenery and large trout is what the Jefferson River is all about.

Beginning at the confluence of the Big Hole and Beaverhead Rivers outside of Twin Bridges, MT, the Jefferson River flows for about 77 miles where it joins the Gallatin and Madison rivers to form the headwaters of the Missouri river. Low pressure and loads of classic “fishy” looking water make this river a prime candidate to grow trout.

Big Guys like these can thrive on the Jefferson River by spreading out due to lower fish numbers than our other Montana Rivers.
