Yellowstone Park

Fall River Basin streams remain high, but fishing with sink tip lines and weighted flies will bring results. Hatches are ongoing, but are compressed. Green drakes, PMDs, and sallys bring afternoon action. No hoppers yet, but ants and beetles are worth trying afternoons. Beware of mosquitoes especially in timber during evenings and horseflies in open areas. Beula Lake continues to provide great action. Try damselfly life cycle patterns.
Fly Patterns to use:
Project Hopper
Lawson’s PMD
Palomino Caddis Tan
