Crooked River Fishing Report — September 10, 2026: World-Class Tailwater Fishing Below Bowman Dam

Crooked River Fishing Report — September 10, 2026

Flow: ~175–200 CFS (Bowman Dam tailwater, per fly shop) | USGS Gauge 14087400: 1,270 CFS (below Opal Springs, downstream gauge) | Water Temp: 55.4°F (13.0°C) | Clarity: Clear | Conditions: Excellent

Current Conditions

The Crooked River below Bowman Dam is fishing exceptionally well this September — arguably the most consistent trout fishery in Central Oregon right now. Water temperatures are a crisp 55.4°F, ideal for energetic, hard-fighting rainbow trout, and the river runs gin-clear through the spectacular canyon below Chimney Rock. Recent fly shop reports (Confluence Fly Shop, 9/4/2026) confirm excellent fishing with great hatch activity throughout the day.

A note on gauge data: The USGS gauge (14087400) below Opal Springs, near Culver, reads 1,270 CFS — this station sits well downstream of the primary fishing reach and incorporates significant cold-water spring inputs. The regulated tailwater directly below Bowman Dam (the Chimney Rock section) is running at approximately 175–200 CFS, confirmed by local fly shop reports. These are excellent, comfortable wading levels through the canyon.

With its renowned 4,000+ trout per mile density and year-round cold releases from Bowman Dam, the Crooked tailwater is in peak fall form. The summer crowds have receded, leaving some of the most productive and accessible water in the Pacific Northwest to those in the know.

What's Hatching

September on the Crooked delivers overlapping hatches that keep trout actively feeding throughout the day. Caddis and PMDs are the primary hatch right now — guides are seeing strong dry fly action, particularly on overcast mornings and afternoons when fish commit to the surface. Midge clusters dominate the early morning, with fish sipping in softer water. Blue-winged olives (BWO) are beginning to show as September light angles drop, and this hatch will only improve through fall. Nymph fishing below the surface remains the most consistent technique regardless of hatch activity — the fish count is hard to beat.

Top Fly Recommendations

• Zebra Midge (#20–22, red/black or olive) — The absolute staple on this tailwater; fish deep under an indicator first thing in the morning
• Pheasant Tail Nymph (#14–18) — Versatile universal nymph; matches PMD and BWO nymphs; excellent as a dropper
• Parachute Adams (#16–18) — The best all-around dry for rising fish; matches PMDs, BWOs, and midges
• Elk Hair Caddis (#14–16, tan) — Afternoon caddis match; fish in and below riffles
• Copper John (#16–18, red or gold) — Gets down quickly in faster runs; excellent tandem with a dry attractor
• Stimulator (#14–16) — Good searching dry in broken pocket water sections of the canyon

Best Access Points

• Chimney Rock Recreation Area (BLM) — Primary access below Bowman Dam; parking, restrooms, easy wade access into prime water
• Crooked River Back Country Byway (Hwy 27) — Paved road runs alongside the canyon with multiple signed pull-outs and walk-in access along the entire reach
• Ogden Wayside (near Terrebonne) — Lower canyon access; open water with plenty of room
• Smith Rock State Park — Lower reach; stunning scenery shared with hikers; productive water especially in morning hours

Tactics & Tips

The Crooked rewards patience and stealth. In crystal-clear water, fish can see everything — use 5X–6X fluorocarbon tippet and leaders of 9–12 feet. Approach fish from downstream, stay low, and avoid casting shadows over feeding lanes. The most productive nymph rig is a two-fly Euro or indicator setup with a Pheasant Tail and Zebra Midge, fished along the seams between fast and slow water where trout hold and intercept food.

Hazards & Regulations

This is an artificial flies and lures only, catch-and-release section — barbless hooks required. Respect the regulations that maintain this world-class fishery. Afternoon canyon heat in early September can be intense; carry plenty of water and apply sun protection. Rattlesnakes are active on rocky outcroppings and brushy banks. No access closures or fire restrictions known as of this report.
