Deschutes River Fishing Report — August 4, 2026: Summer Caddis in Full Swing
Elk Hair Caddis, Stimulator, Chubby Chernobyl, Parachute Adams, Copper John, Pheasant Tail Nymph, Woolly Bugger
Current Conditions
The Lower Deschutes is in solid summer form heading into August. USGS Gauge 14103000 at Moody (near Biggs, OR) recorded 3,800 cfs as of this morning — elevated for peak summer but well within fishable range. The Maupin section above Sherars Falls typically runs 15–20% lower than the Moody gauge. Water clarity is good with 3–4 feet of visibility, and the water temperature is a trout-friendly 62°F (16.6°C) — right in the sweet spot for aggressive surface and subsurface feeding.
Hatches & What's Working
August on the Lower Deschutes means one thing above all: caddis. Evening caddis flights — primarily tan and olive species — are firing hard from 6:00 PM through dark. Fish are crushing dries in riffles and along seams. The Elk Hair Caddis (#14–16, tan or olive) is the go-to right now, and the Stimulator (#10–14, orange or yellow) is also producing beautifully, doubling as a stonefly imitation in faster pocket water. A Chubby Chernobyl (#10–12) will draw aggressive strikes in broken water throughout the afternoon.
Daytime dry-fly action is picking up on PMDs (#16–18) from late morning through midday — a Parachute Adams in the right size will fool selective fish feeding in the softer seams. For subsurface work, nymph two flies under an indicator and lead with a Copper John (#14–16), trailing a Pheasant Tail Nymph (#16–18) 18 inches behind. Early mornings before hatches start are prime time for this setup in the deeper slots. Swing a Woolly Bugger (olive or black, #6–8) through tailouts in the low light — you'll find both resident trout and potentially a summer steelhead.
Best Access Points
Prime access in the Maupin area includes the boat launch at Maupin City Park, Heritage Landing, and BLM day-use areas along Hwy 216. Above Sherars Falls, the canyon road provides wade access to excellent dry-fly water in the riffles and runs near town. Below Sherars Falls, a drift boat is the preferred method for covering water down through Mack's Canyon and South Junction. Wading is moderately challenging at current flows — studded felt wading boots are strongly recommended.
Hazards & Closures
⚠️ Wildfire smoke has been present in the Maupin corridor this summer. Check ODFW and ODF fire maps before heading out. Conditions can change rapidly in the canyon — be prepared to cut the day short if smoke thickens. Rattlesnakes are active in August along rocky banks; watch your step when off-trail. No current closures on the Lower Deschutes as of this report. Always verify current ODFW regulations before fishing.
