Yellowstone Park, October 24th, 2023

This can happen during the late season

All brown trout runs are in full swing, but those close to roads are well attended by fly fishers (Gardner, Madison, Snake Rivers). Fewer attending fly fishers are on the Lewis River channle or at Lewis Lake outlet thanks to the weather conditions. Those conditons will worsen for the rt of the weeks, so be prepared for bad road conditions, snow, wind and reduced Park services. Presenting streamer or big nymph patterns of choice are the best ways to encounter aggressive browns this time if the season.
