The Snake at Moose is running 7,070 CFS at 54.1°F — flows are dropping fast off a historically low 22% snowpack, and the river is clearing weeks ahead of schedule. The post-runoff dry-fly window has arrived right on cue for mid-June, with salmonfly nymphs staging, golden stones building, and BWOs firing hard midday.

Hatch Chart
| Insect | Size | Activity | Prime Time |
|---|---|---|---|
| Blue-Winged Olive (Baetis) | #18–22 | Heavy — best dry-fly opportunity on the river right now | 10 AM – 2 PM; all day on overcast days |
| Midges (Chironomidae) | #20–24 | Active — consistent on the upper tailwater below the dam | Morning & evening; all day on cold or cloudy days |
| Salmonfly Nymphs (Pteronarcys) | #6–8 | Nymphs migrating — adults not yet flying in numbers | All day; fish soft seams and undercut banks |
| Golden Stonefly | #8–12 | Building — adults beginning to appear on warmer afternoons | Early afternoon through dusk |
| Early Caddis (Brachycentrus) | #14–16 | Sporadic — beginning to appear in afternoon windows | 2 PM – dusk |
Best Time Window
- 7:00 AM – 9:30 AM — Midge and nymph window; dead-drift heavy stonefly nymphs and midge patterns through soft seams before the sun hits the water
- 10:00 AM – 2:00 PM — Prime BWO dry-fly window; look for rising cutthroats in flats and eddies as the Blue-Winged Olive hatch fires under the sunny skies
- 4:00 PM – Dusk — Caddis and golden stone afternoon; skitter caddis dries along the banks and swing streamers through the deeper tailouts as light fades
Guide's Tip
From the benchWith flows dropping fast from the 7,070 CFS peak and the river clearing ahead of schedule, focus your morning on nymphing the soft seams and inside bends with heavy stonefly patterns — the salmonfly nymphs are on the move. By 10 AM, shift your attention to the slower flats and eddies where BWOs will start popping; look for subtle rises from Snake River finespotted cutthroats sipping in the foam lines. The sunny forecast (highs 67–72°F) will push the best dry-fly action into that 10 AM–2 PM window, so don't sleep in. As the afternoon heats up, swing a streamer through the deeper channels or switch to a caddis dry along the willowed banks as the evening caddis flight begins.
