Snake River Fishing Report

Week of April 7, 2026 — April 13, 2026

Current Conditions

Flow (CFS) 920 at Moose
Water Temp 38°F – 42°F
Clarity Crystal — 6+ feet of visibility
Wadeability Excellent

Flows are steady at 920 CFS from the dam release. Water is gin-clear with 6+ feet of visibility. Midges are the dominant hatch here — look for clusters in the slower seams and eddy lines from late morning through early afternoon. BWOs are starting to show in sparse but fishable numbers, especially on overcast afternoons. Nymphing with small midge patterns (sz 18-22) under an indicator is the most consistent producer. Wade access is excellent with low, stable flows.

What's Hatching

Midges

Heavy

10 AM — 2 PM, peaking around noon

Dense clusters in slower water. Fish are keying on emergers just below the film. Look for subtle head-and-tail rises in the foam lines and soft edges.

Blue-Wing Olives (Baetis)

Moderate

1 PM — 4 PM, best on cloudy days

Sporadic but building. Overcast afternoons trigger the best hatches. Fish will rise freely when enough duns are on the water — watch the banks and back eddies.

Skwala Stoneflies

Sporadic

Warmest part of the day, 12 PM — 3 PM

Just starting to appear on warmer afternoons, mainly in the lower reaches. Not enough density to generate consistent surface activity yet, but worth carrying a sz 10 Skwala pattern as a searching dry.

What's Producing

Dry Flies

Griffith's Gnat 18-20

Imitates a midge cluster on the surface. Best during peak midge activity around noon. Target foam lines and slow eddies.

Parachute Adams 16-18

The ultimate searching dry and indicator fly. Fish it as a lead fly in a dry-dropper rig with a midge nymph trailing 14 inches below.

Nymphs & Droppers

Mercury Midge 18-22

Dead-drift in the film under an indicator. The go-to pattern right now — fish it in every soft seam you find.

Zebra Midge 18-20

Black or red body. Great dropper behind a Parachute Adams. Fish it 12-18 inches below the surface.

Streamers

Woolly Bugger (Olive) 8-10

Strip slow through deeper runs and along undercut banks. Early morning before the hatch gets going or late afternoon when activity slows.

Emergers

RS2 Emerger 20-22

Deadly when fish are keying on emerging BWOs just below the film. Fish unweighted in the top 6 inches.

Best Time and Section This Week

Peak Windows 11 AM — 2 PM
Best Section Moose to Wilson Bridge

Guide's Take

This is classic early spring fishing on the Snake. The midges are doing exactly what we expect — building in intensity as the days get a little longer and warmer. The BWOs are the exciting story this week. We're seeing real numbers for the first time this spring, and the fish are starting to look up. If you can time it right on a cloudy afternoon, you'll get rising fish on dry flies. It doesn't get better than that in April.

Next Week's Outlook

Expect warming temperatures through mid-April to push BWO hatches into stronger territory. Skwala stoneflies should become more consistent in the lower reaches as afternoon highs climb. Flows will remain stable from the dam — ideal wading conditions should hold through the month. The week of April 14 looks like it could be the turning point where dry fly fishing becomes the primary game. Book midweek trips for the best shot at uncrowded water during peak hatch windows.

Conservation Note

Early spring fish are hungry but recovering from a long winter. Practice catch-and-release, keep fish wet, and use barbless hooks. Water temps below 40°F mean slower recovery times — minimize handling and get fish back in the current quickly. If you see spawning redds (cleaned gravel patches), give them a wide berth.

Early spring on the Snake. Flows are low and stable, midge activity is building, and the first Skwalla stoneflies of the year are starting to show. This is the quiet window before runoff — and this year, a historically low snowpack may mean it stays quiet longer than usual.

Common Questions This Week

What flies should I bring for Snake River fishing in early April?

Focus on midges and early Blue-Wing Olives. Carry Mercury Midges and Zebra Midges in sizes 18-22 for nymphing, Griffith's Gnats for surface midge clusters, and Parachute Adams in 16-18 as a dry-dropper indicator fly. An RS2 Emerger in 20-22 is essential when BWOs start popping. A few olive Woolly Buggers in size 8-10 round out the box for streamer work in the morning.

Can you wade the Snake River in April?

Yes — April is one of the best months for wade fishing on the Snake. Flows are typically stable at 800-1,100 CFS from the Jackson Lake Dam release, well below summer runoff levels. Wading conditions are excellent to good throughout most of the river. Felt-soled or studded boots are recommended as cobble can be slippery. A wading staff is helpful but not essential at current flows.

What is the best time of day to fish the Snake River in spring?

Late morning through early afternoon (11 AM - 2 PM) is the sweet spot in early April. That's when water temps rise enough to trigger midge hatches and get fish actively feeding. On cloudy days, BWO hatches can extend the action into mid-afternoon. Early mornings and late evenings are typically slow as water temps drop below 38°F. If you only have a half day, book the morning-to-afternoon slot.
