Yellowstone Park

Brown trout runs in Gibbon, Madison and Lewis Rivers are in full swing. The same can be said of fly fishers accompanying them. The same will take place soon on the Gardner and Snake Rivers. Sales of streamer patterns and materials to tie them are sky high in regional fly shops.
Fly Patterns to use:
Brook’s Sprout-Baetis
