Lower Deschutes River — August 14, 2026
Flow: 3,830 CFS (USGS gauge 14103000, Deschutes at Moody) • Water Temp: 65°F (measured 5:45 AM PDT) • Clarity: Clear
The lower Deschutes is fishing well on this mid-August Friday, though conditions demand an early alarm and some tactical adjustments. Flows are running a robust 3,830 CFS — well within summer norms for the lower canyon — and clarity is excellent throughout the Maupin corridor. Be aware that lingering wildfire smoke from surrounding ridgelines may affect visibility and air quality; check AQI before heading out and consider a buff or mask for extended wade sessions.
Hatches & Timing
August on the Deschutes means one thing above all else: caddis. Evening caddis flights from Maupin downstream through Locked Gate and Macks Canyon are exceptional right now, with fish rising freely from roughly 6:00–8:30 PM. An Elk Hair Caddis in sizes #14–16 is your bread-and-butter dry fly — fish it with a downstream skitter or a dead drift along seam edges. The Chubby Chernobyl in golden/tan doubles beautifully as both a hopper and a high-visibility attractor through the afternoon heat, with water temps nudging 65°F by midday and trout pushing into shaded riffles, undercut banks, and deeper tailouts.
Morning anglers should prospect with a Stimulator in yellow or orange (#12–14) for early-rising cuttbows, or swing a Stimulator through broken pocket water above Sherars Falls. Trico spinners are active in the early morning flat sections — a size #20 Parachute Adams covers you nicely when the spinner fall is on.
Nymph & Subsurface Tactics
When the surface is quiet, a two-fly nymph rig does the work. Lead with a Copper John (#14–16, red or copper) as your anchor fly and trail a Pheasant Tail Nymph (#16–18) 18 inches behind. Fish pocket water and runs in the 2–4 foot depth range. High summer means fish are thermoregulating — focus on the shady side of the river and fish are concentrated near the bottom during the 11 AM–4 PM heat window.
Access Points
- Above Sherars Falls: The White River access and Harpham Flat provide excellent wade fishing. The wade trail below Maupin City Park (south bank) offers dependable caddis water at dusk.
- Below Sherars Falls: Locked Gate, Macks Canyon, and South Junction BLM sites offer primitive camping and walk-in access to lightly pressured runs. A valid Oregon fishing license and Combined Angling Tag are required for steelhead areas.
- Sherars Falls itself: Native American treaty fishing is active — please respect tribal dip-net operations and maintain distance from the falls platform.
Hazards & Notes
Water temps will peak near 68–70°F on exposed afternoon stretches. Practice catch-and-release with care: use a rubber net, minimize air time, and revive fish thoroughly before releasing — especially if fishing midday. If temps rise above 67°F in your section, consider stopping fishing until evening cooling. Wildfire smoke may be intermittent; Maupin-area AQI has been variable. Check AirNow.gov before your trip.
Steelhead begin showing in the lower Deschutes in August — a swung Woolly Bugger in black or olive on a floating line through tailouts and classic holding water is always worth a few casts at dawn and dusk.
