Yellowstone Park

On all waters cloudy skies with high relative humidity make for the best mid-day fishing this time of year. On meadow streams a repeating theme applies: given bright atmosphere conditions mid-day fishing is not as successful as early in the day or evening fishing. Patterns for spinner falls and terrestrial insects can be most effective during these times of day, and as we advance through fall months streamer patterns become important in attracting larger trout.
Fly Patterns to use:
