Crooked River Fishing Report — August 17, 2026
Current Conditions Overview
The Crooked River tailwater is delivering some of the finest fly fishing in Central Oregon right now. Stable dam-regulated flows, near-perfect water temperatures, excellent clarity, and active insect hatches are all lining up beautifully this August. If you can only make one fishing trip this week, the Crooked River is a strong case for your destination.
Flow & Water Temperature
The USGS gauge 14087400 (below Opal Springs, near Culver, OR) is reporting 1,240 CFS as of this morning. Note that this station is downstream of Opal Springs — a major spring contributor — so the prime upper tailwater section between Bowman Dam and approximately Mile Marker 8 runs at considerably steadier and lower flows, offering comfortable wading conditions throughout. Water temperature is a near-perfect 55.6°F (13.1°C). Cold dam releases keep this tailwater fishing in a prime range even through the hottest August days. Visibility is excellent — crystal-clear water from top to bottom.
Active Hatches
PMDs (Pale Morning Duns) are showing up in increasing numbers beginning around late morning and continuing into early evening — currently the primary dry fly event on the Crooked. Caddis activity has picked up noticeably this week, with smaller black caddis and tan caddis (#16–18) working both as dries and as nymph imitations. Midges are active throughout the day year-round on this tailwater and should not be overlooked, especially in the foam lines and slower pools. Leeches and scuds are always effective on the Crooked as searching patterns and fish them with confidence when hatches aren't happening.
Top Fly Recommendations
- Parachute Adams (#14–16): Covers the PMD hatch beautifully — a sparse tie in clear water is most effective. Fish the foam lines and flat tailouts during the afternoon rise for the best action.
- Elk Hair Caddis (#16–18, black or tan): Match the increasingly active caddis. Size down and go sparse — the Crooked's clear water demands precise presentation.
- Zebra Midge (#18–22): A year-round producer on the Crooked. Deadly in bubble lines, riffles, and anywhere fish aren't locked onto the PMD or caddis hatch.
- Pheasant Tail Nymph (#14–16): Nymph the seams and riffles in the morning before the hatch. Dead-drift it with a split shot or drop it under a Chubby — a must-have for this river.
- Copper John (#14–16): Excellent heavy dropper below an indicator or a Chubby Chernobyl. Gets PMD nymphs and caddis pupae down to fish holding in faster runs and deeper slots.
- Woolly Bugger (#8–10, black or olive): Swing or strip-retrieve through deeper pools and runs in early morning. The Crooked's wild redband rainbows and mountain whitefish will hammer a well-presented streamer.
Best Access Points
- Bowman Dam Trailhead: Top of the tailwater. Hike downstream for the most productive and least-pressured water immediately below the dam.
- Crooked River Ranch Access: Multiple BLM and public pullouts along the canyon road. Gradual riffles make for comfortable wading — great for all skill levels.
- Lower Canyon (Mile Marker 4–8): Spectacular canyon scenery with a mix of riffles, runs, and pools. Hike in for solitude and the chance at bigger fish.
- Lone Pine Road Pullouts: Multiple roadside access points between Terrebonne and the ranch make it easy to sample several sections in a single outing.
Hazards & Regulations
⚠ Rattlesnakes: Always watch your step in the rocky Crooked River canyon in August. Rattlesnakes are active — stay on paths and watch where you put your hands when scrambling on rocks.
🌡 Heat: Even though water temps are perfect, canyon air temperatures can push 95–100°F in August. Start early, carry plenty of water, and take shade breaks. Fish are most active during morning (7–11 AM) and late afternoon/evening (5–7 PM).
🎣 Regulations: The Crooked River tailwater below Bowman Dam is artificial lures and flies only, catch-and-release for trout. Barbless hooks are strongly encouraged to protect wild redband rainbow trout. Always verify current ODFW regulations before fishing.
