North Fork Shoshone Fishing Forecast
The North Fork Shoshone anchors Wyoming trout culture for anglers who want a forecast that respects real hydrology—not a generic “fish today” badge. Species mix centers on rainbow trout, brown trout, and cutthroat trout, with tactics shifting from weighted nymphs in cold water to dries and terrestrials as afternoons warm during late June through September. Because it is not a manicured park stretch, the North Fork Shoshone rewards map work, respectful access, and leaders sized for the clarity you will actually see. USGS gauge 06281000 tracks live flow and temperature for planning wade or float days.
Below the dam, the North Fork Shoshone is running at steady flows through 58°F water — 6/10 today. Top pick: a LaFontaine's Deep Pupa.
