Main Stem Snake River

Increased flow for irrigation slows fly fishing somewhat in the river above American Falls Reservoir. Diversions cause change in flow levels throughout.  The best fly fishing is from Tilden Bridge down to the reservoir because of cool inflow from numerous springs. Flow here is about 4250 cfs. Boating is the safest and most effective way to fish.  Wading remains dangerous. Streamer and woolly bugger patterns on sink tip or full sinking lines with stout leaders are best producers under these conditions. All boat launch ramps are open. Flow below American Falls Dam is about 10850 cfs, so wading there is dangerous.  This flow is ideal for boating and makes all launch sites easily used.
