Top 5 Wyoming Rivers Fishing This Week | April 2026

The Green River is currently flowing at 418 cfs (normal) with a stable trend. Flows are fishable today. The Verdict: Excellent Fishing Conditions This week’s forecast shows temperatures ranging from 27-41°F. Cooling temperatures may slow hatch activity.

Insect Activity: Midges dominate the headwaters right now with sporadic BWO activity on overcast afternoons — the snow showers today should trigger a solid midge hatch between 11am and 2pm. Size 18-22 Zebra Midges and Rojo Midges are the go-to subsurface patterns. Watch for midge clusters on the surface in the slower pools; a Top Secret Midge trailed behind a Psycho Prince covers both options.

Where to Fish: At 418 cfs the headwaters are wading comfortably. Focus on the deeper runs and soft seams where the river braids below the canyon — trout are stacking in the slower water out of the main current. The inside bends hold fish tight to the bank. Work a two-nymph rig dead-drift through the gut of each run and let it swing at the tailout before picking up.

Gear Tip: Start with a streamer rig in softer edges. Switch to a two-fly nymph rig and a yarn indicator as flows settle. 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.

The Green River is currently flowing at 418 cfs (normal) with a stable trend. Flows are fishable today. The Verdict: Excellent Fishing Conditions This week’s forecast shows temperatures ranging from 33-48°F. Cooling temperatures may slow hatch activity.

Insect Activity: Midge activity picks up noticeably in the Warren Bridge stretch as the valley widens and water temps climb a few degrees by midday. Expect concentrated emergence between noon and 3pm, especially in the back eddies. BWO spinners can show up late afternoon when the snow clears. A size 20 WD-40 is deadly as a dropper behind a Hare’s Ear Nymph in the film.

Where to Fish: This section fishes best from the bank — work the long, glassy runs between Warren Bridge and the Daniel access. At normal flows the gravel bars are exposed and the trout hold in the defined channels between them. Hit the foam lines along the willows and any seam where fast water meets slow. A longer leader (12-foot, 5X) helps in the clear, flat water here.

Gear Tip: Start with a streamer rig in softer edges. Switch to a two-fly nymph rig and a yarn indicator as flows settle. A 9-foot 5X leader with light tippet keeps the rig natural in these flows.

The Green River is currently flowing at 418 cfs (normal) with a stable trend. Flows are fishable today. The Verdict: Excellent Fishing Conditions This week’s forecast shows temperatures ranging from 34-49°F. Cooling temperatures may slow hatch activity.

Insect Activity: The Daniel to La Barge section sees the same midge and early BWO patterns as upstream, but the wider valley catches more wind which can shut down surface activity by early afternoon. Below the surface, Pheasant Tail Nymphs in sizes 16-18 are producing consistently in the riffles. Egg patterns — Nuke Eggs in pink and peach — are still effective this time of year as some browns finish spawning.

Where to Fish: This is bigger water with long sweeping bends and deep outside corners. At 418 cfs it’s wadeable in most spots but watch your step on the cobble — felt soles or studs are worth it. The best fishing is in the first 100 yards below each riffle where the current compresses into deeper runs. Swing a Soft Hackle Hare’s Ear through the transition water at the tail of each pool for aggressive takes.

Gear Tip: Start with a streamer rig in softer edges. Switch to a two-fly nymph rig and a yarn indicator as flows settle. 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.

The New Fork River is currently flowing at 295 cfs (normal) with a rising trend. Flows are fishable today. The Verdict: Excellent Fishing Conditions This week’s forecast shows temperatures ranging from 36-54°F. Cooling temperatures may slow hatch activity.

Insect Activity: The New Fork is running slightly warmer than the Green and showing earlier midge emergence — hatches can start by 10am on sunny stretches. At 295 cfs the water is clear and fish are keyed on small patterns: size 20-22 Miracle Midges and Rojo Midges fished in the film. When the sun breaks through, watch the shallow riffles for rising fish — a Parachute BWO in size 18 is worth having ready.

Where to Fish: The Big Piney section has excellent bank access and plenty of wadeable riffles and pocket water. At current flows, the mid-river gravel bars create defined feeding lanes — position yourself on the inside and cast to the deeper seam along the far bank. Don’t overlook the undercut banks along the willows; some of the biggest fish in this section hold tight to structure and will eat a well-placed Egg-Sucking Leech swung on a sink-tip.

Gear Tip: Start with a streamer rig in softer edges. Switch to a two-fly nymph rig and a yarn indicator as flows settle. 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.

The Snake River is currently flowing at 305 cfs (normal) with a rising trend. Flows are fishable today. Water Temperature: 41°F (cold). The Verdict: Excellent Fishing Conditions This week’s forecast shows temperatures ranging from 36-48°F. Cooling temperatures may slow hatch activity.

Insect Activity: Spring on the Snake near Moran means midges are the main event with occasional stonefly nymph movement along the bottom. Snow showers today will keep surface activity brief but intense — watch for midge clusters in the slack water behind boulders. Size 18 Rainbow Warriors and Psycho Prince nymphs are producing well in the faster runs. The Snake’s cold snowmelt-fed water keeps insect activity compressed into the warmest two hours of the day.

Where to Fish: The Snake near Moran is braided and powerful at 305 cfs — stick to the side channels and back eddies where the current slows enough to wade safely. The gravel bars between braids concentrate fish and create excellent nymphing lanes. Fish the transitions where side channels rejoin the main current — trout sit in the soft water waiting for food to wash in. A strike indicator rig with enough split shot to bounce bottom is the most productive setup right now.

Gear Tip: Start with a streamer rig in softer edges. Switch to a two-fly nymph rig and a yarn indicator as flows settle. 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.
