Bozeman Fishing Reports

Posted by: Toby SwankCurrent Conditions
The Bozeman area is starting to change quickly with the warmer weather we’ve had during the days. Even with cooler nights helping stabilize things in the mornings, flows across a lot of the area rivers are starting to bump. It’s looking more and more like this could be the beginning of runoff.
The Gallatin has come up quite a bit and picked up color. Fishing has become tougher, but there are still fish to be found along the banks and in slower water. Heavier nymph rigs fished thoroughly through softer seams have been the best approach.
The Yellowstone has also been on the rise. Caddis are still around in good numbers, but the added water and color have made dry fly fishing more challenging compared to earlier in the week. Softer edges and slower banks are becoming more important each day.
The Lower Madison has continued to fish well and remains one of the more consistent options around Bozeman right now. Caddis and yellow sallies have been showing in the afternoons, and nymphing with crayfish patterns to smaller perdigons underneath has been productive.
The Upper Madison is still in good shape overall. Flows have increased slightly, but the river remains fishable and both nymphing and streamer fishing have been productive. March browns are still around, although wind has probably been the biggest challenge most afternoons.
Things are changing fast right now around Bozeman. If the warm weather continues, runoff is likely not far off on a lot of the freestone rivers.
