Deschutes River Fishing Report — August 21, 2026

USGS Gauge 14103000 (Deschutes at Moody): 3,890 CFS  |  Water Temp: 64.8°F  |  Clarity: Clear  |  Conditions: Good

Current Conditions Overview

The lower Deschutes is fishing well heading into the weekend. Flow at the Moody gauge is holding steady at 3,890 CFS — classic late-August summer flows that keep the river wadeable in the upper canyon and navigable by drift boat from Maupin all the way to the mouth. Water temperature logged in at 64.8°F this morning, sitting just below the stress threshold for redband trout. Clarity is excellent — the river is running clear green through the basalt canyon, with strong bottom visibility in waist-deep water. One heads-up: patchy wildfire smoke is present in the Maupin corridor; air quality may affect comfort, but it's not impacting the fishing.

What's Hatching

August on the Deschutes means one thing above all else: caddis. The spotted sedge hatch (Hydropsyche, sizes 14–16) is firing aggressively each evening from roughly 6 PM to dark, triggering explosive surface-feeding from the resident redbands and early-returning summer steelhead. Morning action opens with a solid Blue-Winged Olive (Baetis, sizes 18–22) window from 9 AM to noon on the glassy flats and transition zones. Pale Morning Duns (PMDs, sizes 16–20) make a brief but fishable appearance mid-morning. Early risers will find midge clusters (sizes 20–24) from first light until around 10 AM in the slower inside bends. The evening caddis show is the headline event — position yourself in the tailouts and riffles as the canyon walls throw shade around 6 PM and prepare for one of Central Oregon's premier dry-fly experiences.

Top Fly Recommendations

• Elk Hair Caddis (#14–16, tan/olive) — The quintessential Deschutes caddis dry. Dead-drift it through the tailouts, then skate it across current seams as dusk falls. Fly #1 right now, full stop.
• Stimulator (#12–14, orange/yellow) — Doubles convincingly as a golden stonefly and caddis attractor. Excellent searching pattern in broken water and pocket water sections above Maupin.
• Chubby Chernobyl (#8–10) — Use as a dry-dropper indicator rig during midday. Drop a Pheasant Tail Nymph 18–24 inches below it through fast runs and pocket water for consistent action between hatches.
• Parachute Adams (#16–18) — Reliable all-day searching pattern and a solid match for the BWO and PMD windows in calmer water. The high-vis parachute post is a real advantage when tracking the fly in low-light conditions.
• Pheasant Tail Nymph (#14–18) — The subsurface workhorse. Set your indicator to 1.5x the water depth and run enough split shot to keep the fly ticking the bottom through main-channel runs. Deadly through the fast riffles above Sherars Falls.
• Zebra Midge (#20–22, black/chrome) — Essential in the first two hours after dawn. Fish the slower inside seams and along the soft edges of riffles where midges congregate.
• Woolly Bugger (#4–6, black or olive) — For steelhead hunters, swing a Woolly Bugger through the classic boulder-studded runs below Sherars Falls. Let it dead-swing through the deep pools and strip it back through the current seams.

Access Points and Logistics

Above Sherars Falls (Maupin Area): The most popular wade-fishing and day-float stretch. Launch at Harpham Flat or Beavertail to drift the upper canyon. BLM campsites along Hwy 216 provide walk-in wade access to multiple run-riffle complexes. Below Sherars Falls: Access by drift boat from Macks Canyon or via the primitive road system. This section holds the best summer steelhead water on the river. The road from Maupin to the mouth is currently open — confirm current conditions with the Deschutes Canyon Area BLM Prineville District before heading out.

Hazards and Notes

• Heat: Afternoon highs in the canyon are reaching the upper 80s°F. Redband trout experience thermal stress above 68°F water temp — focus pressure in the early morning and evening windows. Land fish quickly and keep them in the water during release.
• Smoke: Patchy wildfire smoke is present in the Maupin area today. Check AQI at AirNow.gov before your trip and consider an N95 for sensitive individuals.
• Rattlesnakes: Late-summer desert conditions increase rattlesnake activity along canyon trails and river banks. Watch your footing, especially on rocky outcroppings.
• Regulations: The east bank of the Deschutes is closed to salmon and steelhead angling from the mouth to Sherars Falls. Review current ODFW emergency regulations before targeting steelhead.
