Jefferson forms when three of our favorite rivers -- the Big Hole, Beaverhead and Ruby -- converge near Twin Bridges, Montana.

Giant cottonwood bottoms of the Jefferson Valley.

The Jefferson forms when three of our favorite rivers -- the Big Hole, Beaverhead and Ruby -- converge near Twin Bridges, Montana. The Jeff flows through the giant cottonwood bottoms of the Jefferson Valley between the Tobacco Root and Highland mountains and varies from lazy, wide slicks to braided channels that pour over classic gravel bars into long, fishy runs. From the Jefferson Valley, the river winds through a spectacular canyon before emptying out into the Gallatin Valley where it meets the Madison and Gallatin Rivers to form the Missouri.

Needless to say, floating the Jefferson should be a must for any fly fisher.

Produces a tremendous amount of food for its trout.

The Jefferson River produces a tremendous amount of food for its trout; from crawfish and sculpin to caddis and tons of stoneflies, the Jeff offers anglers a diverse array of fishing options.

We’re convinced a record brown trout lurks in the Jeff, but you can also bet on catching some spirited rainbows too. This is big water best fished from a boat, and with great fishing and majestic mountains towering above, we think you’ll be plenty content to cast, relax and enjoy the float.
