Henry's Fork of the Snake River - Lower (Below Ashton Reservoir), Idaho Fly Fishing Reports & Conditions
My tips of the week
Look for fish rising early and later in the day. During the mid day heat, try running nymphs through deeper pockets of water or a dry dropper rig on the banks. Golden stones tight to the bank without any other trailer fly can also produce a nice big brown or rainbow!

Lower 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

Warm temperatures are here to stay. We have a clear forecast with highs into the 80's in the foreseeable future. Fishing will be most productive early in the morning or late in the afternoon as the sun is not beating down on the fish/water. Look for spent bugs on the water and fish sipping them.
