Yellowstone Park

Streamers and BWO life cycle patterns make for the best fishing almost anywhere. The Madison River drainage also features midge emergences that are bringing fish to the surface. Hoppers are pretty much gone because of hard frosts. In the near future look for some late autumn fisheries to become places to consider. This includes the run of browns into the Gardner River, Trout Lake with its huge cuts and 'bows, and the run of browns into the Snake River.
Fly Patterns to use:
