Lewis River Channel
It’s time to go back to the Firehole River as cooler weather means cooling water to offset the thermal water input. Fall season BWOs and caddis will bring action especially under low light conditions. Some trico spinner falls remain on the Madison River with BWOs are coming on strong. If you prefer to pitch streamers, the Madison River in the Park and the Lewis River between Shoshone and Lewis Lake and just below Lewis Lake are the best places to try, and these waters will see more trout moving in (browns in the Lewis River, browns and rainbows in the Madison River) as we go through October. Brown trout runs in other streams (Gardner, Gibbon, Snake) will peak later in the month. Don’t overlook the Yellowstone River for presenting streamers to large resident cutthroat in areas open to fishing from the lake to the falls. Streamer fishing in Heart, Shoshone, Lewis, and Yellowstone Lakes will improve, but the weather will not, so prepare accordingly especially if you pack into any of these lakes. With killing frosts look for terrestrial insects to diminish, but presenting hopper patterns on meadow sections of all streams will be effective well into October during good weather.
