Lower Deschutes River Fishing Report — October 20, 2026
Current Conditions Overview
The lower Deschutes is reading 4,380 CFS at the USGS Moody gauge this morning (provisional data, gauge #14103000), continuing a recovery from last week's atmospheric-river event that briefly pushed flows to near 6,000 CFS when dam operators opened the flood gates. The good news: the river has crested and flows are trending back down. Water temperature is a healthy 55.4°F (13.0°C) — right in that October sweet spot where redband rainbows and any lingering steelhead are active throughout the day. Expect clarity to be slightly off-color in the lower canyon below Sherars Falls, where the White River injected up to 1,890 CFS of glacial turbidity during the storm; the reach above Sherars Falls is clearing faster and fishing noticeably better. Overall conditions are Good and improving — the trend is your friend right now.
Flow & Gauge Data
USGS Gauge 14103000 – Deschutes River at Moody, OR:
Flow: 4,380 CFS | Water Temp: 55.4°F | As of 6:00 AM PDT, Oct 20, 2026
(Data provisional, subject to USGS revision — always verify before heading out.)
Flows of 4,000–4,500 CFS are on the higher end of the fall fishing window but completely manageable if you wade smart, pick your battles, and focus on the edges. A wading staff and felt spikes are non-negotiable at these levels.
October Hatches & Surface Activity
October is Blue Winged Olive (BWO) season on the Deschutes, and this week is no exception. Expect the primary hatch to fire mid-morning through early afternoon — typically 10 AM to 2 PM — especially under overcast skies or light drizzle. Look for soft-sipping rises along seams, current edges, and the slower tailouts between riffles. Trout keyed on the smaller olives (sizes 16–20) can be maddeningly selective, so match the hatch tight and fish fine tippet (5X).
The other big October event: October Caddis (sizes 8–10, rust/orange body). These large, meaty adults skitter and flutter on the surface in the afternoons, often provoking explosive takes. Concentrate on the last two hours of daylight when October Caddis activity peaks. Mahogany Duns (sizes 14–16) can fill in the midday lull, and midge activity (sizes 20–22) stays steady all day in the calmer flats. With higher flows pushing fish tighter to structure, don't overlook subsurface presentations — even during active dry fly hatches, a high-percentage of fish are eating below the surface.
Top Fly Recommendations
With 4,380 CFS pushing through, nymphing heavy runs and seams is the most consistent producer right now. Here's what's working:
- Pheasant Tail Nymph (sizes 14–16, olive/natural) — the go-to BWO emerger; fish it on a tight-line rig or under a small indicator in the slow slots.
- Zebra Midge (sizes 18–22, black/red) — deadly in the flat water and below riffles; fish two at a time as a midge cluster.
- Copper John (size 14–16, red or gold) — gets down fast in the heavy water, great as the lead fly in a two-nymph rig.
- Chubby Chernobyl (size 8–10, tan/orange) — fish it as an indicator with a Zebra Midge or Pheasant Tail dropper. Doubles as a legitimate October Caddis adult when the hatch fires.
- Elk Hair Caddis (size 8–10, orange/rust body) — the classic October Caddis dry; dead drift it through the tailouts and swing it on the hang-down at end of drift.
- Stimulator (size 8–10, orange) — high-floating attractor and a spot-on October Caddis imitation; deadly swung wet or dead-drifted.
- Parachute Adams (size 16–18) — reliable BWO match and all-day searching pattern for when trout are rising but you can't pin down the exact bug.
- Woolly Bugger (sizes 4–6, black or olive) — streamer fishing picks up in the fall as big fish stack up. Strip it tight to undercut banks and through the deep tailouts for the biggest redband rainbows in the canyon.

Best Access Points
- Above Sherars Falls: Whitehorse, Wapinitia, and Beavertail are the cleanest water right now — less White River influence. Walk-wade from the pullouts along Hwy 216.
- Maupin Area: Heritage Landing, Harpham Flat, and Sandy Beach all provide solid access. Expect bank and gravel-bar fishing over mid-stream wading at current levels.
- Below Sherars Falls (Lower Canyon): South Junction, Oak Springs, and Macks Canyon are accessible via the Lower Deschutes River Road. Clarity is improving but expect slightly off-color water. Drift boat anglers have an advantage here.
- Drift boats: Recommended put-ins at Harpham Flat or Heritage Landing. Run the river early before debris picks up. Clear the water before dusk.
Hazards & Closures
No current fishery closures in effect. At 4,380 CFS, wading requires extreme caution — felt spikes and a wading staff are strongly recommended. Debris (logs, sticks, leaves) may still be present from the recent flood pulse, particularly for drift boaters. Rattlesnakes are retreating to winter dens but can still be encountered on warm, sunny rock outcroppings.
Regulations reminder: Wild steelhead must be released unharmed. Redband trout limit is 5 fish (12" minimum) on most of the lower river — verify current ODFW regulations for the reach you plan to fish, especially above Sherars Falls. USGS data provisional and subject to revision.
