Elk Hair Caddis, Stimulator, Parachute Adams, Pheasant Tail Nymph, Copper John, Woolly Bugger
Deschutes River Fishing Report — August 9, 2026
Lower Deschutes | Maupin Area | Above & Below Sherars Falls
Flows are running a robust 3,800 CFS at the USGS gauge at Moody (14103000) this morning, with water temperatures reading a very fishable 63°F (17.4°C) at dawn — expect temps to tick up a few degrees by afternoon as the canyon heats toward the mid-80s. Clarity is excellent: crystal-clear water with visibility well into the gravel. Overall conditions are good, with the best windows concentrated early morning and in the evening once canyon shadows take over.
Current Conditions & Hatches
Mid-August on the lower Deschutes is all about timing your hatch windows. The most exciting action right now is the evening caddis flight — various species in sizes #14–18 are coming off heavily between 6 PM and dark, triggering aggressive surface rises along current seams and softer edges. This is arguably the best dry-fly fishing the Pacific Northwest offers all year. Get your Elk Hair Caddis and Stimulator rigged before you put the boat in — you won't want to fumble with tippet when the bugs start flying.
Morning fishing is equally productive with a different gameplan. Blue-Winged Olives (size #20–22) are emerging moderately from 7–10 AM on overcast sections, and Pale Morning Duns (size #18–20) are showing lightly from 9–11 AM. A Parachute Adams in #18 is your best all-around imitation for either hatch. Midge activity continues through the early morning hours in flatter tailouts — keep a #20–22 midge dry handy.
For sub-surface action throughout the day, the Pheasant Tail Nymph in size #16–18 is deadly drifted through deeper runs and boulder pockets. Pair it with a Copper John as a dropper to cover both slow and faster water. At 3,800 CFS, fish are stacked in the deeper seams and won't move far during the midday heat — get your nymphs down to the bottom and let them work the slow edges. After sunset, a swung Woolly Bugger through boulder pockets can produce some of the largest redsides of the day.
Access Points
The Maupin City Park boat ramp is your primary put-in for the popular upper section. Harpham Flat (BLM) provides good walk-wade access below town. The Sherars Falls area offers prime wade fishing both above the falls (good dry-fly water in calmer runs) and below (deeper pools for nymphing). Macks Canyon further downstream offers solitude and excellent wade access from the BLM campground. The popular drift section from Heritage Landing to South Junction fishes well all day.
Hazards & Notes
Afternoon westerly winds can gust to 25–30 mph through the canyon — plan your casting accordingly and keep back-casts tight. At 3,800 CFS, wading requires sturdy footing; cleated boots and a wading staff are strongly recommended above Sherars Falls. No current closures reported on the lower Deschutes. Fire season is underway in Central Oregon — check ODFW and local conditions for any access restrictions before heading out. The Deschutes is open year-round for wild redband rainbow trout (catch and release only for wild fish), with steelhead regulations per current ODFW regs.
