Each river featured below has optimal flows, good water quality, and active hatches. These best Wyoming rivers provide diverse fishing opportunities with current Wyoming river conditions that favor active feeding. Whether you’re targeting tailwaters or freestone streams, the top 5 Wyoming rivers this week provide exceptional fishing.
1. Green River – Fontenelle
Central Wyoming
The Green River was flowing on the report date at 843 cfs (normal) with a falling trend. Flows were rated fishable on the report date. The Verdict: Excellent Fishing Conditions Status Update: Reopened Jan 1, 2026 (Annual closure Oct 1 – Dec 31 ended). This week’s forecast shows temperatures ranging from 23-41°F. Calm winds make subtle nymph takes easier to detect.
Insect Activity: Consistent tailwater temperatures support year-round insect activity. Midges and small nymphs are key patterns, while streamer fishing can be productive when targeting larger fish.
Fishing approach: Study deeper runs and tailouts from a confirmed legal fishing position. Adjust depth and weight to the drift you can reach without an uncertain crossing.
Gear Tip: Start with a two-fly nymph rig and a yarn indicator. A 9-foot 5X leader with light tippet keeps the rig natural in winter flows.
Presentation: Dead-drift the nymph rig through slower seams and focus on the warmest part of the day. Add just enough weight to tick bottom every few drifts.
2. North Platte River – Miracle Mile
Central Wyoming
The North Platte River was flowing on the report date at 634 cfs (normal) with a rising trend. Flows were rated fishable on the report date. The Verdict: Excellent Fishing Conditions This week’s forecast shows temperatures ranging from 25-43°F. Calm winds make subtle nymph takes easier to detect.
Insect Activity: Dam releases create stable tailwater conditions ideal for winter fishing. Midges and small nymphs remain active throughout the season, with streamer patterns effective in deeper runs.
Fishing approach: Look for reachable seams beside slower water. A controlled nymph drift can cover the holding lane without moving farther into the current.
Gear Tip: Start with a two-fly nymph rig and a yarn indicator. A 9-foot 5X leader with light tippet keeps the rig natural in winter flows.
Presentation: Dead-drift the nymph rig through slower seams and focus on the warmest part of the day. Add just enough weight to tick bottom every few drifts.

Fishing approach: Fish current breaks and shaded structure from an authorized position. Match the fly and presentation to the activity you observe.
Gear Tip: Start with a two-fly nymph rig and a yarn indicator. A 9-foot 5X leader with light tippet keeps the rig natural in winter flows.
Presentation: Dead-drift the nymph rig through slower seams and focus on the warmest part of the day. Add just enough weight to tick bottom every few drifts.
5. Snake River – Jackson Lake
Northwest Wyoming
The Snake River was flowing on the report date at 289 cfs (low) with a stable trend. Flows were rated fishable on the report date. Water Temperature: 35°F (cold).

Fishing approach: Give a promising seam several controlled drifts, then change depth or pattern. Moving farther along the bank requires a separately confirmed route.
Gear Tip: Start with a two-fly nymph rig and a yarn indicator. A 9-foot 5X leader with light tippet keeps the rig natural in winter flows.
Presentation: Dead-drift the nymph rig through slower seams and focus on the warmest part of the day. Add just enough weight to tick bottom every few drifts.
