Jefferson River Fishing Report

Posted by: Toby SwankCurrent Conditions
The Jefferson River is still worth fishing this time of year, but don't expect numbers like you'd find on the Madison or Missouri. It's a river where finding the right water matters more than anything, and you can cover a lot of ground without finding many trout if you're in the wrong spots. With the colder mornings we've been having, late morning into the afternoon is a good window to focus on.
I'd start with nymphs in the slower runs below riffles and around deeper bends. A crayfish or sculpin pattern trailed by a smaller baetis nymph or perdigon is a good setup. If you're after a larger brown, this is also the time of year to fish streamers. Work the deeper bends and undercut banks with a larger olive or brown pattern, especially when the weather turns cloudy.
