Upper Henry's Fork Description

The North Fork of the Snake river, better known as the world famous Henry's Fork is a river of diversity. From a small stream at it's headwaters near the Mt/Id border, it quickly becomes a full sized river with the meeting of the millions of gallons of water a day, emerging from Big Springs.

Techniques & Tips

Look for rising fish eating adult or emerging midge flies. If there is nothing happening there, nymph or streamer fishing can be extremely productive.
