The Legendary Henry’s Fork – River of Riches
Henry’s Fork, a tributary of the Snake River, is a fly fisher’s dream – teeming with trout and offering a diverse range of fishing environments. Starting in the mountains of eastern Idaho, this lush waterway, loaded with Rainbow, Brown, and Cutthroat Trout, is a fisherman’s paradise. But hold your horses – timing is everything. The river fishes best from May to October, but if you want to wrestle with the big boys, head out in the late spring and early summer when the hatch is in full swing.

Master the Craft – Techniques on How to Fly Fish the River
To fly fish Henry’s Fork like a pro, get these techniques down:
- Dry Fly Fishing – Cast upstream and let your fly float naturally downstream. It’s a classic move and works great in Henry’s Fork.
- Nymphing – Use a weighted nymph under an indicator. Cast upstream and let it drift, mimicking a nymph naturally moving in the current.
- Streamer Fishing – In the fall, try casting and stripping a streamer for those aggressive, big trout.
Rigging Rules – Rigging Your Rod
Rigging for fly fishing involves a fly line, leader, and fly. For Henry’s Fork, opt for a 4 to 6 weight fly line and a 9 to 12 foot leader with a 4X to 6X tippet. Attach the tippet to the leader, then tie your chosen fly to the tippet. When nymphing, aim for a depth of 1.5 to 2 times the water depth.
Know Before You Go – Local Laws and Restrictions
Remember, ignorance of the law is no excuse. Idaho requires all anglers over 14 to have a fishing license, and there are restrictions on the size and quantity of trout you can keep. Check the Idaho Department of Fish and Game website for the latest regulations.
