The Legendary Henry’s Fork – River of Riches

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.

The Path Less Traveled – Fishing with Low Traffic

Want a piece of the river all to yourself? Then the Upper Henry’s Fork, around Big Springs, is your best bet. Less frequented by anglers, it gives you space to master your cast and, more importantly, fish in peace.

Hotspot Alert – The Busiest Fishing Spot

When it comes to the most popular spot, the Railroad Ranch section in Harriman State Park takes the cake. Sure, it gets busy, but there’s a reason all those anglers flock there. The fishing is off the charts!

Gear Up – Ideal Rod and Reel Selection

Fly fishing in Henry’s Fork demands a versatile rod and reel setup. For most situations, a 9-foot, 5 or 6-weight rod will be your weapon of choice, paired with a matching reel loaded with a weight-forward floating line.

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.

Conquer the Henry’s Fork

You’re ready now, armed with all the know-how on how to fly fish the legendary Henry’s Fork. Remember, this isn’t just a sport; it’s an art. An art that brings you closer to nature. So take it slow, savor every moment, and respect the river. Good luck, angler. Now go make some waves!
