Crooked River Fishing Report โ August 28, 2026
Below Bowman Dam (Prineville Reservoir Tailwater) | Terrebonne / Crooked River Ranch Area
Current Flow: 1,250 cfs (USGS Gauge 14087400, Below Opal Springs near Culver โ as of 5:00 AM PDT)
Water Temperature: 55.4ยฐF (13.0ยฐC)
Clarity: Slightly Off
Overall Conditions: Fair
Conditions Overview
The Crooked River is running elevated today at 1,250 cfs โ notably above the typical late-summer baseline of 200โ500 cfs for this tailwater reach. The higher flows are likely the result of increased releases from Prineville Reservoir through Bowman Dam. While the Crooked's tailwater nature generally keeps clarity better than a freestone river would at these flows, anglers should expect slightly off-color water in some sections and faster currents than usual throughout the canyon.
On the positive side, water temperature at 55.4ยฐF is excellent โ cool, well-oxygenated tailwater that keeps trout active and feeding. This is prime temperature range for the Crooked's dense population of redband rainbow trout. Concentrate on slower seams, inside bends, and eddies behind larger boulders where fish can hold out of the heaviest current.
Hatch Report
August is peak Trico season on the Crooked River, and the spinner falls have been impressive. Trico (Tricorythodes) falls happen on calm mornings, typically 7โ10 AM in the slow pools and wide, flat sections of the lower canyon. Fish can be extremely selective during Trico falls โ sipping tiny spinners with a high refusal rate โ so fine tippet (6X or 7X), precise presentation, and patience are critical.
Reports from local fly shops indicate that Pale Morning Duns (PMDs) are showing in increasing numbers in the early afternoon and continuing into the early evening โ a welcome mid-day window of dry fly opportunity. Midge activity is consistent throughout the day, as expected for a year-round tailwater. As temperatures cool into the evening, look for caddis to show in the lower canyon sections near Terrebonne.
Top Fly Recommendations
- Zebra Midge (#20-22, red or black): The Crooked River staple. Fish it deep under an indicator in the slower runs all day long โ it rarely fails.
- Pheasant Tail Nymph (#16-18): Excellent PMD emerger and general nymph imitation. Deadly in the early afternoon ahead of PMD activity.
- Parachute Adams (#18-20): Your best all-around dry for Trico and PMD activity. Highly visible and effective during the morning spinner fall.
- Copper John (#16-18): Gets down fast in the heavier current โ an excellent anchor fly in a two-nymph rig under an indicator.
- Elk Hair Caddis (#16-18): Worth having on for evening caddis activity in the lower canyon reaches near Terrebonne.
- Woolly Bugger (#8-10, olive): With elevated flows, a lightly weighted Woolly Bugger swung through deeper slots and runs can be surprisingly effective for larger fish displaced from their usual lies.
Best Access Points
- Lower Canyon / Terrebonne area: The most popular and accessible stretch. Multiple pull-outs along Lower Crooked River Road (BLM). Good pools, riffles, and tailouts throughout.
- Crooked River Ranch area: Private land predominates โ stick to the designated public access points. Check BLM signage carefully before entering.
- Below Bowman Dam (upper reach): Access via Bowman Dam Road off US-26 east of Prineville. Shorter walk, typically less pressure, excellent tailwater pools directly below the dam.
Hazards and Regulations
- Flows at 1,250 cfs are elevated โ wading is significantly more difficult and potentially unsafe in the channel. Prioritize shallower margins and use extra caution at all crossings. Consider floating sections rather than wading if flows remain this high.
- The Crooked River is a year-round fishery with catch-and-release regulations in most sections. Check current ODFW regulations before fishing โ artificial flies and lures only throughout the catch-and-release zone.
- Flows may fluctuate with dam releases โ check USGS gauge 14087400 the morning of your trip for updated conditions.
- Rattlesnakes are common in the canyon during August โ watch your step on rocky banks and in brushy areas.
