Jefferson River Fishing Report

Posted by: Toby SwankCurrent Conditions
The weather forecast is looking pretty soggy for the next handful of days on Montana’s Jefferson River. Lots of rain and some snow is expected. That being said the river has just shaped up so fishing should be decent. Nymphing will be the best way to get some fish to hand but the streamer route can be a good way to get into some bigger fish. The Jefferson can also get some pretty good Midge and BWO hatches in the spring so keep an eye out.
Our nymph selection is pretty basic, a Pat’s Rubber Leg or a red Worm are go-to lead flies. Below that we are fishing dark shiny Perdigons, Zebra Midges, and Mayfly nymphs. Trying a crawfish pattern or a small streamer under an indicator can also do the trick. Focus your nymphing on the slow deep holes. For streamers keep your fly selection fairly small and fish them slow and deep. A few favorite patterns are Sculpzillas, Mini Dungeons, and Peanut Envy’s

Jefferson River Fishing
The Jefferson River is a unique Montana fly fishing destination. It runs for around 80 miles, surrounded by the rugged landscapes of the Tobacco Root and Highland Mountain Ranges.
Formed where the Ruby, Big Hole, and Beaverhead Rivers converge, it meets the Madison and Gallatin Rivers to form the Missouri River near Three Forks, Montana.
Fishing conditions vary from year to year based on winter snowpack and summer moisture, but it offers solitude and the opportunity to catch big fish. Ideally suited for floating, the Jefferson River has low trout populations. Advanced anglers who are willing to work for a few good trout will enjoy fishing the Jefferson.
