Deschutes River Fly Fishing Report — August 26, 2026
Flow: 3,860 CFS (USGS Gauge 14103000, Moody near Biggs) | Water Temp: 64°F | Clarity: Clear | Overall: Good
Current Conditions
The lower Deschutes is fishing well this Wednesday. Flows have ticked down slightly from 3,940 CFS two weeks ago to a current reading of 3,860 CFS at the Moody gauge — and more importantly, water temperatures have cooled from 67.8°F to a healthier 64.4°F. That shift matters: trout are more comfortable, more active through the day, and pushing into shallower riffles earlier in the evening. Water clarity is excellent with visibility to the bottom in 2–3 foot seams. All signs point to a great evening caddis session ahead.
Heads up: Wildfire smoke has been intermittently present in the Maupin canyon this season. Check AirNow.gov for current conditions before heading out.
What's Hatching
August on the Deschutes is defined by the evening caddis hatch — and the show right now is outstanding. Spotted Sedge (sizes 14–16) are coming off heavy between 6 PM and dark, and fish are hammering dry flies in the tailouts and riffles once the sun drops behind the canyon walls. Morning anglers will find a productive Blue-Winged Olive hatch (sizes 18–22) from 9 AM to noon in the glassy flats, and sparse PMDs round out the midday window. Early risers can pick up fish on midge patterns in softer inside bends before the caddis clock takes over in the afternoon.
- 6 AM – 9 AM: Midge and early BWO nymphing — softer bends and inside flats
- 9 AM – 1 PM: BWO and PMD window — glassy flats and transition zones on fine tippet
- 6 PM – Dark: Prime evening caddis hatch — tailouts, riffles, and the classic Deschutes dry-fly show
Top Fly Picks
- Elk Hair Caddis #14–16 — the essential evening pattern; don't leave the truck without it
- Chubby Chernobyl #10–12 — excellent attractor and caddis imitation in the choppy pocket water above Sherars Falls
- Stimulator #12–16 — skate it through riffles as caddis begin to flutter early evening
- Parachute Adams #16–18 — covers BWO and PMD windows beautifully in the morning; visible and durable
- Pheasant Tail Nymph #14–18 — dead-drift along the bottom through inside seams all day long
- Zebra Midge #20–22 — early morning standard in softer current; pair with split shot
- Copper John #14–16 — heavier attractor nymph for the fast runs between Maupin and South Junction
All of the above patterns are available at bugsnjugs.com — stocked fresh for late-summer Deschutes conditions.
Best Access Points
Above Sherars Falls: Harpham Flat and Beavertail offer excellent wade access and long runs ideal for morning nymphing. The town of Maupin has river access, parking, and shuttle services. Below Sherars Falls: Mack's Canyon and South Junction are prime drift boat water with outstanding caddis fishing in long, glassy tailouts. The BLM road (Mack's Canyon Road) is open; high-clearance vehicle recommended south of mile marker 10.
Hazards & Closures
Water at 3,860 CFS is wade-fishable with caution — wet wading is comfortable at 64°F, but felt soles or studded boots are strongly advised on the slippery basalt. Monitor smoke conditions in the Maupin canyon area. No current fishing closures on the lower Deschutes as of August 26, 2026. Steelhead season opens mid-September — mark your calendars now.
