A pal spent last week fishing the upper Green River in northern Utah, near Flaming Gorge, mostly float-fishing. Browns, Rainbows, some Cutthroat. It's one of the US' most famous trout fisheries.
I tried to find out to what extent that fishery is stocked, but I could not find the answer. Still, except for Lake Trout, almost all trout fisheries in the US are stocked.
He had one day of 24" snow, but otherwise good (chilly) weather and good fishing.
A pic he sent me below, and another below the fold -
