The Jefferson river is the third and final tributary of the Missouri. “The Jeff” originates near Twin Bridges, Montana where the Beaverhead and the Big Hole rivers converge. The Jefferson offers great early season opportunities at some truly large brown trout. But like many great things, they often don’t come easy. This river is hot or cold. It takes a bit of divine intervention and a lot of eternal optimism, but when the stars align, the Jefferson delivers.
Thanks to spawning habitat restoration efforts in the Jefferson Valley, there is also a healthy population of rainbow trout. They get really big too. Really when its good, its pretty damn good. But when its sucks, it really sucks. The Jefferson can dish out great dry fly fishing, prolific hatches, and excellent streamer fishing. The nymphing can also be very productive.
