Salmonfly Peak: Lower Deschutes on Fire — May 22, 2026
Chubby Chernobyl, Stimulator, Elk Hair Caddis, Parachute Adams, Woolly Bugger, Copper John
Current Conditions
The Lower Deschutes is firing on all cylinders right now — the Salmonfly hatch is at full peak from Trout Creek through Maupin, with the hatch front marching hard toward Warm Springs. This is the window you circle on the calendar all year. Redside rainbows are aggressively eating big foam dries slammed tight to undercut banks and shaded canyon walls. If you've been waiting for the right day to hit the Lower D, today is it.
Flow & Water Conditions
USGS gauge 14103000 (Deschutes at Moody, near Biggs) is reading 3,800 cfs as of this morning — elevated for late May but right in line with seasonal snowmelt runoff. Water temperature is 61°F (15.9°C), which is ideal for aggressive surface feeding and puts trout in prime condition throughout the canyon. Water clarity is slightly off-color at current flows; target inside seams, soft bank edges, and shaded canyon walls where visibility improves.
Active Hatches
- Salmonfly (Pteronarcys californica) — #4–6: PEAK. Dense concentrations from Trout Creek to Maupin. Late morning through mid-afternoon is prime time. Fish tight to the banks.
- Golden Stonefly (Hesperoperla pacifica) — #8–10: Strong and building. An excellent backup when salmonfly surface action cools down midday.
- Tan Caddis — #14–16: Heavy afternoon and evening flights. The second act of every day on the Lower D right now.
- PMD / Pale Morning Dun — #16–18: Active late morning in slower softer water.
Top Fly Recommendations
Lead with big foam attractor patterns that match the salmonfly profile and can be spotted in the riffles. Follow with caddis in the afternoon and evenings.
- Chubby Chernobyl #6 — The do-everything attractor for salmonfly season. Slam it under overhanging alders and let it drift without drag.
- Stimulator (orange/yellow) #6–8 — A classic that has been absolutely crushing it during peak stonefly season. High-floating and visible.
- Elk Hair Caddis #14–16 — Heavy afternoon and evening caddis flights make this an essential second fly, or rig it as a dropper off your Chubby.
- Parachute Adams #14–16 — Versatile searching pattern for PMD windows and off-hatch moments when fish are looking up.
- Woolly Bugger (black/olive) #6–8 — Swung through heavy water and deep canyon pools for larger, predatory fish that aren't focused on the surface.
- Copper John #14–16 — Dead-drifted as a dropper beneath your dry for fish holding in deeper seams.
Best Access Points
Maupin City Park Boat Ramp is the hub of activity right now. Heritage Landing (above Sherars Falls) and Beavertail Campground offer excellent wade access in the Maupin corridor. Oak Springs is producing well for bank anglers. Below Sherars Falls, Macks Canyon is worth the drive for solitude and productive runs. Note that Sherars Falls itself is a Class IV–V rapid and a known hazard — do not attempt to run it.
Hazards & Reminders
⚠️ Flows are elevated — wading requires caution, especially at crossings. Use a wading staff and felt soles or cleats on slick basalt. Check USGS gauge 14103000 before launching. The Deschutes is a fly fishing only, catch-and-release river for trout above the deadline at the Warm Springs boundary. Always check current ODFW regulations before you go.
