The current cool weather means the Firehole River is worth fishing again. BWO life cycle and white miller caddis patterns offer good ways to obtain action. So do soft hackle patterns. Be ready for stormy conditions! Look for early in the day trico activity on most streams. Terrestrial insect patterns will continue to work on all streams until a killing frost arrives. Most crowded streams include the Lamar in roadside meadows, Soda Butte Creek, Slough Creek’s lowest meadow (pressure on upper two meadows is thinning), Firehole River, Madison River, and lower Gibbon River on which the upper section is closed due to ongoing native salmonid restoration project.
