Best Flies for Shoshone River (Wyoming)
The Shoshone River in Wyoming fishes as both a wade and a float. It is a tailwater fishery for Brown Trout and Rainbow Trout, with the most reliable window in June, July, August. The patterns below are matched to the hatch chart we publish for this water. They are not a live report of what other anglers caught this week.
This is not a live report of other anglers' catches. Presence and flow live on the Shoshone River river page and the Wyoming destination guide.

Nymphs
Subsurface patterns matched to this river's chart and catalog. Fish them at the size the chart lists, not the size that looks good in the bin.
Dries
Dries and terrestrials for the Shoshone River. If the chart says a size 18 PMD, do not start with a 12.
Streamers
Streamers and wets for stained water, banks, and low light. This is not a claim that streamers are "on" today.
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 Shoshone River?
- Start with Zebra Midge and Griffith's Gnat, then match size to the hatch chart for the month you are standing in. The Shoshone River 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 Shoshone River?
- The editorial window we list is June, July, August, September. 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 Shoshone River?
- 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 Shoshone River?
- Open the Shoshone River 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 We do not publish other people's spots or fish counts.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 Shoshone River?
- 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.
