No catalog patterns in this group yet. Use the hatch chart and the river guide.

Setup

5X and 6X fluorocarbon on nymphs, 5X on dries unless the fish are on Tricos, then 6X or 7X. Start lighter than your home river. One small tungsten and a long tag often beats a 3.5mm bead in clear water. Tight-line the near bank and the heads of pockets. Use an indicator only when you need to search water you cannot euro.

FAQ

What flies work on the Bighorn River (Wyoming)?

Start with BWO Sparkle Dun and BWO Parachute, then match size to the hatch chart for the month you are standing in. The Bighorn River (Wyoming) does not need a 40-pattern box. It needs the right size on the insect that is actually in the drift.

When is the best time to fly fish the Bighorn River (Wyoming)?

The editorial window we list is April, May, June, September, October, November. That is a planning month range, not a guarantee. Shoulder months can fish well if flows and water temperature cooperate.

Do I need a guide on the Bighorn River (Wyoming)?

Wyoming has walk-up wade water and, on some sections, float water. A guide is worth it for a first float or a technical tailwater. A hatch chart and a gauge are enough for a first wade if you already nymph. We list local guides and shops on this page when we have them.

Where can I see live flow for the Bighorn River (Wyoming)?

Open the Bighorn River (Wyoming) river page for the USGS gauge, access notes, and the same hatch chart this fly list is built from. We do not publish other people's spots or fish counts.

Is this a report of what's working now on the Bighorn River (Wyoming)?

No. Executive Angler does not publish other anglers' catches, GPS, or a crowdsourced hot fly. This page is hatch-chart patterns plus catalog flies. Presence on the river page is gauge and weather only.
