Green Fishing Forecast
The Green anchors Wyoming trout culture for anglers who want a forecast that respects real hydrology—not a generic “fish today” badge. Species mix centers on brown trout, rainbow trout, and cutthroat trout, with tactics shifting from weighted nymphs in cold water to dries and terrestrials as afternoons warm during April through October. Because it is tailwater-influenced, the Green rewards anglers who read release schedules and carry both indicators and tight-line rigs. USGS gauge 09217000 tracks live flow and temperature for planning wade or float days.
Spring-fed Green is flowing at 590 CFS CFS with surface temps near 66°F°F — 6/10 today. Top pick: a Parachute Hopper.
