Crooked River — Below Bowman Dam Fishing Report
Report Date: May 27, 2026 | Gauge: USGS 14087400 (Below Opal Springs, near Culver)
Current Conditions
The Crooked River below Bowman Dam is running high at 1,100 cfs (USGS gauge 14087400, provisional) with a water temperature of 54.7°F. This is firmly in irrigation release territory — the Bureau of Reclamation has been pushing significant flows out of Prineville Reservoir to meet downstream irrigation demand, and it shows. At 1,100 cfs, the river is well above the typical 100–300 cfs tailwater fishing range for this stretch. Water clarity is off-color in the main channel, with some turbidity from the increased flow. The good news: temperatures are in a solid range for trout, and fish are still feeding — they've just pushed into slower, softer water to escape the current.
Hatch Report
Despite the high flows, biology doesn't stop. Late May on the Crooked River typically brings the beginning of caddis season — this stretch is known for outstanding caddis hatches from mid-May through June, and even at elevated flows, evening rises are occurring in slack-water pockets, eddies, and along undercut banks. Midges continue to hatch throughout the day as they do year-round on this tailwater. Small Blue-Winged Olives (BWO) are active on overcast afternoons. Pale Morning Duns are beginning to emerge in modest numbers on the lower, slower sections near Crooked River Ranch and Terrebonne. Don't expect much dry fly action in the main channel at these flows, but watch eddies carefully at dusk.
Top Fly Recommendations
- Zebra Midge (#18–22, black/red) — The year-round staple on the Crooked. Fish it deep under an indicator in slow pockets and eddy lines. Non-negotiable in your box right now.
- Pheasant Tail Nymph (#14–18) — Excellent for the PMD and caddis nymphal stages. Fish it behind boulders and in current seams where trout are sheltering from high flows.
- Copper John (#16–18, red) — The weight helps get down fast in higher flows. Use it as the lead fly in a two-nymph rig.
- Elk Hair Caddis (#14–16, tan) — Evening dry fly option in slack water and eddies during caddis activity. Worth trying at dusk even with elevated flows.
- Woolly Bugger (#8–10, olive/black) — Swung or stripped through deeper slots and back-eddies. At 1,100 cfs, bigger fish may be holding in deeper water and will eat a streamer.
- Parachute Adams (#14–16) — All-purpose dry for evening eddy fishing. Light enough to detect subtle rises in slow water.
Access & Logistics
The most productive approach right now is targeting slower water, back-eddies, and protected pockets behind larger boulders and log structures. Key access points include the Crooked River Ranch community access trails, Lone Pine Campground (BLM, mile 7), and the Highway 27 corridor pullouts between Prineville and the Ranch. The uppermost miles just below Bowman Dam will have the fastest, most turbid flow — work the middle and lower sections of the Wild & Scenic reach (miles 5–10) where the river spreads out slightly and more back-eddies form.
Hazards & Closures
Wading is dangerous at 1,100 cfs — this is not a typical tailwater wading day. Many of the flat gravel bars that are easy wading at 150 cfs are now chest-deep and fast. Stay on the bank and use long-leader nymphing rigs or work only the most protected eddy pockets. Flows may fluctuate with irrigation demand — check USGS gauge 14087400 before heading out, as flows can change substantially within a day. No closures are in effect as of this report; catch-and-release only regulations apply throughout the Wild & Scenic reach.
