You won't be angling by yourself, the wind can kick up at times and the multiple hatches can be tough to figure out. Above and below Fontenelle Reservoir, the Green River holds fat rainbow, cutthroat and brown trout. The best way to fish this scenic river is by hiring a guide and floating the Green. Trout will average 12-16 inches but in the lower elevations, you can be surprised by a lunker every now and again. The Green's headwaters begin in the Wind River Mountains to the north and along its southern course to the Flaming Gorge Reservoir, highways run alongside the 100-plus miles.
Many private ranches are open to courteous inquiries about fishing on their land.
Public accesses can be crowded at the height of tourist season but most of the time you'll have entire stretches to yourself. Most folks you'll meet on the river will be locals or townies from Jackson Hole. But you'll need to get on this as of yet undiscovered stretch before everyone else hears about it. Rio Costilla, New Mexico Anglers looking for incredible panoramic vistas of ancient volcanoes, pristine meadow streams and wild trout should look no further. While everyone else is standing shoulder to shoulder on the San Juan, Big Hole or Green Rivers, you could be controlling a couple of miles of this stream, fishing for native Rio Grande cutthroats.
