Henry's Fork of the Snake River - Upper (Above Ashton Reservoir), Idaho Fly Fishing Reports & Conditions
My tips of the week
As some colder & drizzly weather has moved into our area, be on the lookout for a BWO/Baetis hatch. Hopper fishing is still successful but winding down. Try a hopper & bead head nymph dropper rig to find fish when there are no hatches. Streamers are always a safe bet this time of year as well.

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. Tail water sections, broad flats, isolated canyons, plunging waterfalls and long riffles flowing through farmlands all ...

Techniques & Tips

Fishing from a drift boat is our preferred method of fishing on the lower Henry's Fork. However it is one of the best wade fishing rivers around. Try fishing a larger dry fly followed by a smaller dry fly. If they are not keyed in on the Dry flies, try substituting out the smaller dry fly for a weighted nymph. The dry dropper rig can be incredibly effective.

7-Day Forecast

Cooler weather has moved in and we are hoping to see some of our first solid BWO/Baetis hatches.
