Jefferson River Fishing Report

Posted by: Toby SwankCurrent Conditions
The Jefferson River is a difficult fishery right now. Water temps are climbing into the low 70s by midmorning, and hoot owl restrictions are in effect, meaning all fishing must wrap up by 2 p.m. This is an early game. If you’re not on the water at first light, odds are you’re already behind.
Morning is your best (and really only) window to find feeding fish. Hopper-dropper setups have been the most consistent, especially with tan or yellow foam bugs trailed by a small nymph or crayfish imitation about 2 to 3 feet below. The bite window is short, but if you hit those inside seams and shaded banks just after sunrise, you’ve got a real shot at a few quality fish.
By 11 a.m., things slow down fast. The upper river near Twin Bridges is still offering a bit of hope for anglers looking to cover water and avoid crowds. It’s not a numbers game, but the occasional solid brown is still showing up if you work for it.
Lower down toward Three Forks, things get even tougher. Irrigation pulls are warming the water quickly, and trout are disappearing into the deep stuff. At that point, it’s time to reel up and head for cooler options.
If you’re up for an early mission and want to explore one of Montana’s quieter summer rivers, the Jefferson can still deliver, but only if you’re out there before the sun takes over.
