When to Come to Missoula for Fly Fishing

This is one of the most common questions we get, and the honest answer is there’s no bad time to fish in Missoula. But there are better times for specific rivers, specific hatches, and specific kinds of fishing. Here’s a breakdown of what each season looks like so you can plan your trip around what matters most to you.

Spring: March through May

Spring is when the season starts waking up and some of the most exciting early dry fly fishing happens. Skwala stoneflies come off on the Bitterroot, Clark Fork, and Rock Creek in March and April, often before the crowds arrive. Blue Winged Olives and Western March Browns follow. Pre-runoff spring fishing can be very good, with fish that have been largely undisturbed through the winter responding well to a well-placed fly.

Runoff typically begins in late April and can blow out the lower elevation rivers for a few weeks in May depending on the snowpack. During runoff the Clark Fork gets muddy first, but Rock Creek clears fast due to its high gradient and the Missouri River barely notices because it’s a tailwater. A good guide knows where to fish during runoff. There’s almost always somewhere worth being.

Spring is a good time to visit if you want to avoid summer crowds and don’t mind variable conditions. The fish don’t know it’s shoulder season.

Summer: June through August

Summer is peak season in Missoula for a reason. The Salmonfly hatch on the Blackfoot River in mid-June is a dry fly event that draws anglers from all over the country. Big flies, aggressive fish, and the kind of surface action that makes people understand what all the fuss is about. Golden Stones, Green Drakes, PMDs, and Tan Caddis follow through July and into August across all the rivers.

Hopper fishing picks up through August and is one of the most fun ways to fish any of the rivers around Missoula. Slap a big foam fly against a grassy bank and hold on.

June through September are the busiest months. Rivers see more angling pressure. Early mornings and evenings are where it’s at in the heat of summer. Our guides know this and plan accordingly.

Fall: September through November

Fall is when a lot of experienced anglers prefer to fish Missoula. The crowds thin out, the weather cools down, and the fishing gets remarkably consistent. Blue Winged Olives and Mahoganies come off across all the rivers. The Clark Fork in fall can produce pods of 30 to 50 rising fish at once. Brown trout start moving and feeding aggressively as the water cools. Streamer fishing picks up across all the rivers as water temperatures drop.

October on the Bitterroot, the Blackfoot, or Rock Creek is as good as fly fishing gets in western Montana. If you have flexibility in your schedule, fall is worth serious consideration.

Winter: December through February

Winter fishing in Missoula is real but limited. Rock Creek stays fishable through mild winters. The Missouri River below Holter Dam stays fishable through winter because the dam keeps water temperatures stable, though it’s a couple hours from Missoula and we only run Missouri trips on a limited basis.

Most people don’t plan a winter fly fishing trip to Missoula, but if you’re in the area and the weather is reasonable, there’s water worth fishing.

The Short Answer

Summer for hatches and peak season. Fall for consistency and solitude. Spring for early dry fly action and lower pressure. Any time for the Missouri.
