Deschutes River Fishing Report – September 30, 2026
Flow: 4,060 CFS (USGS Gauge 14103000, Moody/Biggs) | Water Temp: 59.7°F | Clarity: Slightly Off | Conditions: Good
Overview
The lower Deschutes is showing classic late-September character today — flows are running at 4,060 CFS at the Moody gauge near Biggs, a seasonal uptick from summer lows as irrigation diversions begin winding down across the upper basin. Water temperature is a sweet 59.7°F, sitting squarely in the prime feeding window for both wild redband trout and early fall steelhead. Expect slightly off-color conditions in exposed tailouts and riffles; pocket water and seams near structure are fishing clean.
Current Conditions
Above Sherars Falls in the Maupin corridor, trout are active throughout the day with the best windows occurring mid-morning (10 AM–noon) and again in the late afternoon as light drops off the canyon walls. The elevated flows have pushed fish tighter to the banks and into current seams along boulder gardens — wade carefully and work the edges. Below Sherars Falls, steelhead are actively moving through and anglers swinging the classic Maupin-to-Mack's Canyon runs are encountering B-run fish pushing upstream ahead of the October peak. This is one of the most exciting times of year on the lower river.
Hatches
Fall is announcing itself on the Deschutes. Blue-Winged Olives (BWOs) are emerging throughout the morning hours, especially under cloud cover — size 18–20 is the ticket. Mahogany Duns are making an appearance in the flatter water, particularly in sheltered coves and slower side-channels. Early October Caddis adults are beginning to show at dusk — that big orange bug will draw explosive dry fly takes from both trout and steelhead holding in tailouts. Midges continue to fill in the gaps throughout the day, especially in slow glassy sections.
Top Fly Recommendations
- Elk Hair Caddis (#12–14, orange/tan) – Match the early October Caddis flush; deadly in late-afternoon on riffle tailouts. Available at bugsnjugs.com.
- Stimulator (#10–14, orange) – The quintessential Deschutes caddis attractor; swings well for steelhead in the runs below Sherars. Available at bugsnjugs.com.
- Parachute Adams (#18–20) – Nails the BWO and Mahogany Dun hatch mid-morning; high-visibility white post aids tracking on broken water. Available at bugsnjugs.com.
- Woolly Bugger (black/olive, #4–6) – Go-to for swinging steelhead below Sherars Falls; use a weighted version on a slow sink-tip through deeper buckets. Available at bugsnjugs.com.
- Pheasant Tail Nymph (#16–18) – Dead-drift through riffles and pocket water above Sherars for trout keying on nymphing BWOs. Available at bugsnjugs.com.
- Copper John (#16, red/gold) – Excellent search pattern and dropper under a dry fly; the flash gets attention in slightly off-color water. Available at bugsnjugs.com.
Best Access Points
- Heritage Flats / Maupin City Park – Easy wading access to classic dry fly water above Sherars; limited parking at peak times — arrive early.
- Harpham Flats – Below Sherars Falls, prime steelhead swing water with a boat launch available for drift boat access.
- Locked Gate / South Junction – Walk-in access to less-pressured trout and steelhead water; hike in 1–2 miles for solitude and fish that haven't seen much pressure.
- Mack's Canyon – Downstream anchor for drift boats; excellent deep steelhead holding runs — a must-fish stretch in October.
Hazards & Notes
At 4,060 CFS, the Deschutes is not beginner wading water. Felt soles with aluminum studs and a wading staff are strongly recommended. Watch for rattlesnakes on rocky canyon banks — they remain active through September on warm afternoons. No emergency closures or emergency rules in effect as of today. Campfire restrictions may still apply in the canyon corridor — check with ODFW and BLM before your trip. The steelhead season is open; retain regulations for wild vs. hatchery fish.
