Lower Deschutes River Fishing Report
Date: Saturday, May 23, 2026 | Gauge: USGS 14103000 – Deschutes River at Moody
Current Conditions
If you have been waiting all year for the Lower Deschutes salmonfly hatch, your window is right now. As of this morning the hatch front is at full peak between Trout Creek and Maupin, with the leading edge pushing toward Warm Springs. Flows are elevated at 3,800 CFS (USGS gauge at Moody, 5:45 AM PDT) due to ongoing late-season snowmelt from the upper basin, and a flood watch is in effect from Maupin downstream to the mouth through the weekend. Water temperature is a comfortable 61°F (16.2°C) — ideal for aggressive dry-fly takes.
Flow & Clarity
At 3,800 CFS the river is running higher than ideal for wading the canyon but remains fishable, especially from a drift boat or raft. Clarity is slightly off due to snowmelt turbidity; visibility is approximately 2–3 feet. Boat anglers will have a distinct advantage this weekend — wade fishing is possible at known shallow flats but exercise caution near Sherars Falls and any swift tailouts. Respect the flood watch: conditions can shift quickly.
Hatches
The Giant Salmonfly (Pteronarcys californica) is the main event right now — large adults are crawling on streamside willows and alder from sunrise through mid-morning and again in late afternoon. Golden Stoneflies are also emerging alongside the salmonflies and will continue for the next 2–3 weeks. Evening caddis activity is picking up, with sporadic Pale Morning Dun (PMD) hatches in slower glassy sections during midday. Expect the salmonfly peak to advance toward Warm Springs by mid-next-week as temperatures rise.
Top Fly Recommendations
Dry Flies (fish the banks):
- Chubby Chernobyl (#6–8, orange/black) — the go-to salmonfly imitation; dead-drift tight to the willows
- Stimulator (#6–8, orange) — classic salmonfly pattern; also works stripped slightly through riffles
- Elk Hair Caddis (#12–14, tan/brown) — evenings when caddis are active; skated or dead-drifted
- Parachute Adams (#14–16) — reliable search pattern for PMD and generalist rises midday
Nymphs (high-water backup):
- Copper John (#12–14) — gets down fast in elevated flows; excellent attractor nymph below riffles
- Pheasant Tail Nymph (#14–16) — PMD/stonefly emerger imitation; fish under an indicator in seams
Access Points & Notes
Primary access: Harpham Flat (above Maupin), Maupin City Park boat ramp, Oak Springs, and Locked Gate takeout. Above Sherars Falls the canyon section offers excellent dry-fly water from a drift; below Sherars Falls at Wapinitia and toward Macks Canyon, boat access is best. Spring Chinook are present in the lower river — please be mindful of redds and handle any incidental catches with care. Check ODFW regs: the lower Deschutes has important seasonal closures and wild fish retention rules in effect.
Flow data: USGS provisional, subject to revision. Always check current conditions before launching. Wear your PFD — flood watch is in effect.
