Top 5 Wyoming Rivers Fishing This Week | June 2026

The North Platte River is currently flowing at 477 cfs (normal) with a stable trend. Flows are fishable today. The Verdict: Excellent Conditions This week’s forecast shows temperatures ranging from 55-73°F. Calm winds support dry fly presentations.

Insect Activity: The upper North Platte is in full June stride, with golden stonefly adults crawling the rocks and taking flight through the morning hours — a size 4-8 Stimulator or Pat’s Rubber Legs beneath the surface will pull fish before the surface action kicks in. By afternoon the PMD hatch dominates, with size 16-20 Sparkle Duns and Comparaduns producing consistent dry fly takes in the riffles and runs. As evening approaches, caddis (size 14-16 Elk Hair Caddis or X-Caddis) take over and extend fishing into last light, making a full-day wade session here worthwhile.

Where to Fish: At 477 cfs, this section is in prime wading territory — wade the rocky riffles and boulder-pocket water above Saratoga during morning stonefly activity, then move to the long glassy runs and pool tails once the PMD hatch fires at midday. The seams between fast and slow water hold fish stacking on drifting nymphs all morning; switch to dries when you see the first rises in the slower flats. Artificial-only water means these fish are educated but catchable on well-drifted presentations — keep your approach low and fish upstream with a 9-foot 5X leader.

Gear Tip: Start with a two-fly nymph rig and a yarn indicator early. Shift to dry fly or dry-dropper during hatch windows. A 9-foot 5X leader with light tippet keeps the rig natural in these flows.

Presentation: Start shallow, then add weight or depth as you move into deeper runs and pockets. Use longer drifts to cover tailouts and seam water.

Regulations: Artificial flies & lures only

The Green River is currently flowing at 499 cfs (normal) with a stable trend. Flows are fishable today. The Verdict: Excellent Conditions This week’s forecast shows temperatures ranging from 61-79°F. Calm winds support dry fly presentations.

Insect Activity: The Green River city stretch is seeing solid afternoon PMD activity (size 14-18) and reliable caddis through the evening, with midges keeping fish interested from first light through the morning in size 18-24. Watch for brief golden stonefly action in the morning along the rocky margins — a size 14-16 soft hackle or beadhead nymph fished as a dropper is a good backup during the transition between hatch windows. Afternoon thunderstorms are in the forecast mid-week, so target the PMD window between 11am and 2pm before weather builds to the west.

Where to Fish: With 499 cfs, the Green is floatable and also has excellent wade access around Expedition Island — the flat runs above and below the bridges concentrate fish during the PMD hatch and are easy to read. Focus on the seams along the island channels and the slower flats below the rapids where trout set up feeding lanes. When thunderstorms push in mid-afternoon, drop down to nymphing the deeper runs with a Copper John or Pheasant Tail — these fish will keep feeding subsurface through the weather.

Gear Tip: Start with a two-fly nymph rig and a yarn indicator early. Shift to dry fly or dry-dropper during hatch windows. A 9-foot 5X leader with light tippet keeps the rig natural in these flows.

Presentation: Start shallow, then add weight or depth as you move into deeper runs and pockets. Use longer drifts to cover tailouts and seam water.

Regulations: Creel limit: 3 trout/day (streams), no more than 1 exceeding 16 inches. Maximum 3 hooks, flies, or lures per line. No special gear restrictions….

The Bighorn River is currently flowing at 1260 cfs (normal) with a stable trend. Flows are fishable today. The Verdict: Excellent Conditions This week’s forecast shows temperatures ranging from 68-86°F. Calm winds support dry fly presentations.

Insect Activity: The Boysen tailwater at Thermopolis is pushing 1,260 cfs with clear, temperature-controlled water — midge activity is the consistent backbone here, with size 20-24 Zebra Midges and Mercury Midges producing fish during the midday warm-up. PMDs emerge through the afternoon (size 16-18 thorax patterns or Sparkle Duns) and give the big browns and rainbows something to key on at the surface; the clear tailwater makes for technical dry fly fishing, so use 5X and keep your presentations drag-free. Caddis continue to fire in the late afternoon and into evening on size 14-18, rounding out a full day’s worth of hatch opportunity.

Where to Fish: Focus on the Wedding of the Waters canyon section where deep slots along the rock walls hold big trout stacking behind boulders and along current breaks. In the morning, midge fishing under an indicator in the deeper flat runs is the most reliable strategy — a Zebra Midge or WD-40 in size 22-24 at the right depth produces consistently. When the PMD hatch fires mid-afternoon, watch the long glassy flats below the canyon entrance for rising fish and approach from downstream with short accurate casts; with air temps near 88°F and potential afternoon thunderstorms, plan to be off exposed water by 3pm.

Gear Tip: Start with a two-fly nymph rig and a yarn indicator early. Shift to dry fly or dry-dropper during hatch windows. A 9-foot 5X leader with light tippet keeps the rig natural in these flows.

Presentation: Start shallow, then add weight or depth as you move into deeper runs and pockets. Use longer drifts to cover tailouts and seam water.

Regulations: WGFD Area 2: 3 trout/day, no more than 1 over 16 inches. Open year-round. Flow gage (06274300 at Basin) is a downstream proxy ~50…

The Salt River is currently flowing at 417 cfs (normal) with a stable trend. Flows are fishable today. The Verdict: Excellent Conditions This week’s forecast shows temperatures ranging from 50-68°F. Cooling temperatures may slow hatch activity.

Insect Activity: The Salt River in Star Valley is firing on all cylinders in early June, with morning golden stonefly activity (size 8-14 Stimulators, golden stone dries) giving way to afternoon PMD hatches that produce aggressive surface takes from Snake River cutthroat and cutbow trout. Caddis round out the evening with reliable action on size 12-18 Elk Hair Caddis and X-Caddis patterns through last light, and midges keep fish active in the slower pools through the morning warm-up. This is one of Wyoming’s most underappreciated freestone streams, and the six-species mix here means every bend can produce something different.

Where to Fish: The stretch from Etna downstream through Freedom has the best wade access and the most varied structure, with gravelly riffles, undercut banks, and long runs that all hold fish at 417 cfs. Work the riffles hard with dry-dropper rigs during the morning stonefly window — a size 10 golden stone on top with a size 16 PMD nymph dropper covers both hatches at once. When the afternoon PMD hatch kicks in, slow down and work the pool tails and flat runs where rising fish set up feeding lanes; these cutthroat will take well-presented Sparkle Duns and Parachute Adams in size 14-16.

Gear Tip: Start with a two-fly nymph rig and a yarn indicator early. Shift to dry fly or dry-dropper during hatch windows. A 9-foot 5X leader with light tippet keeps the rig natural in these flows.

Presentation: Start shallow, then add weight or depth as you move into deeper runs and pockets. Use longer drifts to cover tailouts and seam water.

Regulations: General Area 1 regulations: 3 trout/day (streams), no more than 1 exceeding 16 inches, no more than 1 cutthroat exceeding 12 inches. Maximum 3…

The Gibbon River is currently flowing at 97 cfs (normal) with a stable trend. Flows are fishable today. The Verdict: Good Conditions This week’s forecast shows temperatures ranging from 44-62°F. Cooling temperatures may slow hatch activity.

Insect Activity: The Gibbon River near Madison Junction is crystal clear at 97.6 cfs, with small PMDs (size 18-22) producing selective surface feeding during the midday window from roughly 10am to 2pm. Caddis activity builds through the afternoon and into evening on size 14-18 patterns, with golden stoneflies providing action along the rocky reaches during the morning hours. Midges are a constant presence in the slower glassy stretches — a size 18 caddis pupa dropper fished under a size 20 midge dry is worth running during the transition between hatches on these wary Yellowstone fish.

Where to Fish: The meadow sections between Madison Junction and Gibbon Falls offer the most consistent dry fly fishing, with visible rising fish in the flat, clear runs during the PMD window — approach from downstream and fish 5X-6X tippet with accurate drag-free presentations. Fish stack in the deep pools near the falls cascade and in the pocket water above, where they’re less selective but still require a careful drift. A Yellowstone park entrance pass is required; Yellowstone regulations apply throughout this section (artificial flies and lures only, barbless hooks, no bait), and the lower Gibbon from Madison Junction to the Madison confluence opens June 1.

Gear Tip: Start with a two-fly nymph rig and a yarn indicator early. Shift to dry fly or dry-dropper during hatch windows. A 9-foot 5X leader with light tippet keeps the rig natural in these flows.

Presentation: Start shallow, then add weight or depth as you move into deeper runs and pockets. Use longer drifts to cover tailouts and seam water.

Regulations: Artificial flies & lures only; Barbless hooks required; No bait allowed
