Salt River Fishing Forecast

The Salt River anchors Wyoming trout culture for anglers who want a forecast that respects real hydrology—not a generic “fish today” badge. Species mix centers on snake river cutthroat trout, brown trout, and rainbow trout, with tactics shifting from weighted nymphs in cold water to dries and terrestrials as afternoons warm during April through October. Because it is not a manicured park stretch, the Salt River rewards map work, respectful access, and leaders sized for the clarity you will actually see. USGS gauge 13027500 tracks live flow and temperature for planning wade or float days.

Spring-fed Salt River is flowing at 363 CFS CFS with surface temps near 58°F°F — 7/10 today. Top pick: a LaFontaine's Deep Pupa.
