Archived report — 2025-12-15: Flows, forecasts, ratings and fishing observations below describe that original week, not today. They do not establish safe wading or current access.
Introduction
The top 5 Wyoming rivers this week are fishing better than most anglers expect for mid-December. I watched midges pop in a Miracle Mile tailout last Thursday while frost still clung to the willows, and it reminded me why winter windows are worth chasing. Each river below has steady flows, clear water, and enough insect activity to keep trout feeding. Use this top 5 Wyoming rivers this week report to lock in a primary plan and a backup before the next cold front.
Call to Action: Pick one river tonight, check flows, and fish it within 48 hours.

|---|---|---|---|---|
| North Platte River – Miracle Mile | Central Wyoming | 634 CFS • Rising | 5/5 Excellent | Zebra Midge, Rainbow Warrior |
| North Platte River – Fremont Canyon | Central Wyoming | 69 CFS • Stable | 5/5 Excellent | Pheasant Tail Jig, Pat’s Rubber Legs |

1. North Platte River – Miracle Mile
Current Flow: 634 CFS (normal) Trend: Rising Condition Rating: Excellent (5/5)
What’s Working Now: Midges and small mayflies dominate. Start with a two-fly nymph rig, then swing a small streamer late in the afternoon. The best window is late morning to early afternoon once the sun hits the water.
Top Flies: Zebra Midge, Pheasant Tail Jig, Rainbow Warrior, Pat’s Rubber Legs

2. North Platte River – Fremont Canyon
Current Flow: 69 CFS (normal) Trend: Stable Condition Rating: Excellent (5/5)
What’s Working Now: Clear water favors precise presentations. Keep drifts tight to seams and switch to lighter split shot if you start ticking rocks. The most consistent bite happens once the canyon warms slightly.
Top Flies: Pheasant Tail Jig, Zebra Midge, Top Secret Midge, Pat’s Rubber Legs

3. North Platte River – Grey Reef
Current Flow: 501 CFS (normal) Trend: Stable Condition Rating: Excellent (5/5)
What’s Working Now: Grey Reef stays steady with deep nymph rigs and small emergers. Focus on tailouts and slower seams where trout stack in winter. If you see a brief surface push, be ready with a BWO emerger.
Top Flies: Zebra Midge, Scud, Rainbow Warrior, BWO Emerger
4. Snake River – Jackson Lake
Current Flow: 289 CFS (low) Trend: Stable Condition Rating: Good (4/5)
What’s Working Now: Tailwater stability keeps midges active. Work slower seams and avoid moving too fast; the fish slide into softer water this time of year. Expect short, steady feeding windows.
Top Flies: Hare’s Ear Jig, Zebra Midge, Rainbow Warrior, Pat’s Rubber Legs

5. Salt River
Current Flow: 410 CFS (normal) Trend: Falling Condition Rating: Good (4/5)
What’s Working Now: Winter freestone conditions call for slow drifts in deeper pools. Concentrate on protected bends and use longer tippet when the water is glassy.
Top Flies: Griffith’s Gnat, Zebra Midge, Pheasant Tail, Pat’s Rubber Legs
Wyoming Rivers This Week: Fishing Outlook
These top 5 Wyoming rivers this week are producing with consistent flows, clear water, and active midges. Expect the strongest action from late morning through early afternoon when the water warms slightly. If you only fish one day, use the top 5 Wyoming rivers this week list as your priority order.
Why These Wyoming Fly Fishing Rivers Are Peaking
This Wyoming river fishing report leans on the same signals every winter: stable releases, clean water, and predictable insect timing. When those line up, you get the best Wyoming fly fishing windows of the season, even if the air feels brutal. The five stretches above are the Wyoming fly fishing rivers that stay fishable when other systems lock up.
Use these dated observations for fishing context. Confirm a specific entry and current conditions independently; this report does not establish year-round road access or a short walk to the water.
Winter Playbook for This Week
- Fish the warmest stretch first, then return to it for the last light window.
- Shorten your drifts and reset often instead of hiking long distances.
- Run a two-fly nymph rig, then swap to a small streamer when clouds build.
- Extend to 5X or 6X if the water is clear and pressure is high.
- Keep an eye on shelf ice near the banks, especially late in the day.
Midweek Tactics That Keep Fish Biting
If you can fish outside the weekend rush, midweek windows are money. I plan for shorter sessions and focus on one run at a time, which keeps drifts cleaner and avoids wasting energy hiking long sections. Start with a confidence nymph rig, then rotate one fly every 20 minutes if you are not getting touches. That rhythm keeps you engaged and helps you find the exact depth band where winter fish are stacked.
When wind picks up, drop to inside seams and fish closer. When the sun breaks out, expect a short midge pop that is worth swapping to a tiny emerger. And if snow is falling, stay on the water anyway. Some of the best Wyoming fishing conditions show up when the road feels empty and the bank grass is frosted.
Using this archived report
Treat the river rankings, temperatures, flow readings and fly suggestions in this report as a record of its original publication week. A favorable rating from that week does not describe conditions on a later visit. Compare the dated observations with the current report for the same river section before making a new plan. Check the observation time as well as the value; a historical flow reading cannot confirm today’s water level.
Choose a specific destination before checking access. A river name can cover multiple reaches with different owners, entry routes and fishing rules. Start with information from the responsible land manager for the exact place you intend to visit. Confirm where entry and parking are permitted, whether a route crosses private property, and whether any closures or restrictions apply. A mapped ownership boundary or a roadside space alone does not answer those questions.
Use the app’s available map layers and river information as planning references, then confirm the details with current agency information and posted signs. Download any supported offline maps before leaving service, and remember that downloaded information reflects the data available at the time. Keep an alternative destination in mind if your planned entry is closed, unavailable or unsuitable when you arrive.
Before You Go
- Verify access and parking on each river page (links above).
- Review Wyoming Game and Fish regulations before you travel.
- Bring layers and hand warmers for cold mornings.
- Respect private land boundaries and posted signs.
Conclusion
The top 5 Wyoming rivers this week deliver the best winter fly fishing opportunities across the state. Fish the mid-day window, keep your drifts slow, and use these river reports to stay one step ahead.

Planning a New Trip
Use WGFD’s site-specific Public Access Areas directory to investigate a specific entry and its restrictions. FlyGuysNLies Mobile’s available public-land and property-boundary layers can help you plan; confirm parking and the route with the responsible manager and posted signs. An archived forecast, highway shoulder or visible gravel bar does not establish permission.
Access, closures and fishing regulations can change. Confirm current access permissions and restrictions with the managing agency before visiting. Maps and property boundaries are planning aids and do not establish permission to enter. See our Terms of Use.
