About the Snake
The Snake River is a huge river with more than one personality. In Idaho, fly anglers know it best for the South Fork below Palisades Dam. That tailwater runs more than 60 miles to the Henrys Fork near Menan, and Highway 26 follows much of it. The Snake carries Gold Medal and Wyoming Yellow Ribbon designations.
The fish are Yellowstone cutthroat, Snake River cutthroat, redband trout and bull trout. Farther down the river you will also find Chinook salmon, smallmouth bass, common carp and white sturgeon. Cutthroat and bull trout have special rules in many places, so read the current Idaho regulations before you fish.
Floating is the main way to fish the South Fork. Popular ramps include Byington, Conant, Lorenzo and Menan. The headwaters in Wyoming offer good wading. Below Jackson Lake the river is best floated through Jackson Hole, and the fish get bigger as you go downstream. The Henrys Fork is close by if you want a different kind of water.
The river is known for salmonflies and golden stoneflies in early summer, plus pale morning duns, blue-winged olives, March browns, skwalas and midges at other times. Hopper season and the October caddis round out the year. March and April bring fewer people. August and September are the busiest, and dry fly fishing picks up in early July.
Smallmouth bass anglers should look at Massacre Rocks State Park near American Falls and Hells Gate State Park near Lewiston.

Tips for fishing the Snake
-
Float it with a guide the first time
The South Fork is big, fast and deep in places. A guide shows you the channels, the ramps and the water worth stopping to wade.
-
Plan around the crowds
March and April are quieter. August and September are the most popular months, so book ramps and shuttles early.
-
Carry the classics
Woolly Buggers and Elk Hair Caddis are local favorites. Add stonefly and hopper patterns for summer.
-
Try the bass water
The lower Snake is an excellent smallmouth fishery. Poppers and baitfish streamers work well around rocks and slow edges.
-
Handle protected fish with care
Bull trout and cutthroat have special rules in many sections. Keep them in the water and release them quickly.
