Crooked River Fishing Report — August 21, 2026

USGS Gauge 14087400 (Crooked River below Opal Springs, near Culver): 1,170 CFS  |  Water Temp: 55.6°F  |  Clarity: Slightly Off  |  Conditions: Fair

Current Conditions Overview

The Crooked River tailwater is running elevated this week. The USGS gauge below Opal Springs near Culver is recording 1,170 CFS — higher than the typical summer baseline, reflecting increased releases from Bowman Dam driven by peak irrigation demand. Flows will be lower in the uppermost section nearest Bowman Dam and increase as Opal Springs contributes its significant cold-water inflow downstream. Water temperature is an outstanding 55.6°F, kept cold year-round by the deep reservoir and Opal Springs — a major advantage over the Deschutes right now during the August heat. Clarity is slightly off due to the elevated flow, but visibility is still reasonable in 2–3 feet of water. Wading requires extra caution in the mid-river sections; stick to the edges and shallower margins.

The good news: the fish are still eating. The Crooked's wild redband rainbow trout and mountain whitefish are resilient tailwater fish that tolerate higher flows well, and the cold temps mean they are energetic and willing to feed throughout the day — not just in the morning and evening windows like on warmer rivers this time of year.

What's Hatching

The most recent reports (August 16) confirm that caddis are the dominant surface bug right now — specifically smaller black caddis (sizes 16–18) and a slightly larger tan variety (sizes 14–16). These are showing up all day, with increased activity in the afternoon and evening. Pale Morning Duns (PMDs, sizes 16–18) have been appearing in good numbers in the early afternoon and extending into evening — the hatch has been building since early August and is now in its prime. For nymphers and subsurface anglers, scuds, midges, small stonefly nymphs, leeches, and PMD nymphs are all producing reliably throughout the day. The Crooked is one of those rivers where you can always catch fish subsurface even when surface action is slow.

Top Fly Recommendations

• Elk Hair Caddis (#14–18, black or tan) — Match the smaller black caddis (#16–18) or the larger tan variety (#14–16) depending on what you're seeing on the water. Dead-drift in the seams and riffles, especially in the early afternoon.
• Parachute Adams (#16–18) — An excellent all-purpose dry that imitates PMDs and caddis alike. High-vis for easy tracking in riffled water, and fish it confidently during the afternoon PMD window.
• Pheasant Tail Nymph (#14–18) — The go-to PMD nymph imitation. Nymph this below a small indicator through the mid-depth runs; fish are stacking in the deeper cuts along the canyon walls.
• Zebra Midge (#18–22, black/chrome or red/silver) — Midges hatch on the Crooked every day of the year. Fish these in the slower, softer water and in the margins where foam lines concentrate food. Dead essential in low-light conditions.
• Copper John (#14–16) — A heavy, attractor-style nymph that gets down fast in the elevated flows. Excellent as a lead fly in a two-nymph rig, with a smaller Zebra Midge or Pheasant Tail as the trailer.
• Woolly Bugger (#6–8, olive or black) — Leeches work year-round on the Crooked. Swing or dead-drift a Woolly Bugger through the deeper pools and along undercut banks for the biggest fish in the river.
• Chubby Chernobyl (#10–12) — Use as a foam indicator in a dry-dropper rig during midday, with a Pheasant Tail or Copper John dropper. The Crooked's clear-water fish can be leader-shy — use a fine tippet (5X or 6X) and a longer leader.

Access Points and Logistics

Below Bowman Dam (Upper Tailwater): The stretch from Bowman Dam downstream to approximately Mile Marker 8–12 is the heart of the fishery. This is where wild redband trout densities are highest. Access via Hwy 27 along the river canyon — pullouts and informal access points are available throughout. Chimney Rock Area (BLM): A scenic and popular wade-fishing section with good parking and canyon trail access. The BLM's Wild and Scenic corridor provides public access through most of the prime fishing water. Crooked River Ranch: Private land sections exist — stay below the high water mark and respect posted property. The river corridor through the state recreation area near Terrebonne provides additional public access.

Hazards and Notes

• Elevated Flows: At 1,170 CFS at the Culver gauge, wading is challenging in mid-river sections. Use a wading staff, wear a belt around your wader jacket, and avoid crossing in fast water above knee depth. Fish the softer edges and margins.
• Cold Water: The Crooked runs cold year-round (55.6°F today). Full waders are recommended even in August — neoprene socks or lightweight fleece layers inside your waders will keep you comfortable.
• Access: Some river-front land near Terrebonne and Crooked River Ranch is private. Respect landowner property and posted signs. The BLM Wild and Scenic corridor provides ample public access for most anglers.
• Year-round fishing: The Crooked River tailwater is open to year-round fishing for trout and whitefish. Check current ODFW regulations for catch-and-release requirements and any emergency order updates before your trip.
