Crooked River Tailwater Fishing Report
Date: July 19, 2026 | Gauge: USGS 14087400 (below Opal Springs, near Culver) | Gauge Reading: 1,140 cfs* | Water Temp: 56°F | Clarity: Clear
*Note: The USGS gauge (14087400) is located below Opal Springs, a major natural spring that contributes approximately 750–900 cfs to the river. Flows in the prime tailwater fishing section above Opal Springs — from Bowman Dam downstream toward Crooked River Ranch — are significantly lower, running approximately 200–300 cfs based on recent reports. This distinction is important for wading anglers planning a trip.
Current Conditions
The Crooked River tailwater is in outstanding shape right now, and if you haven’t made the drive to Terrebonne yet this summer, this is your cue. Water temperatures checked in at a near-perfect 56°F this morning — a stark and welcome contrast to the warming conditions on the Deschutes. Flows in the tailwater section below Bowman Dam are running around 200–300 cfs, creating excellent wading conditions through the canyon. Clarity is crystal clear, as this dam-controlled reach stays clean throughout the summer. The Crooked is one of Central Oregon’s most underappreciated fisheries, and July is exactly when it earns its reputation.
What’s Hatching
The caddis hatch has taken center stage and is becoming more prolific by the week. Expect activity starting around 10 AM, with a midday lull, then a strong resurgence from 2 PM through evening. Brachycentrus (Mother’s Day Caddis) has given way to mixed Hydropsyche species. PMDs (Pale Morning Duns) are still present, particularly in morning slots, and small midges remain a reliable sub-surface staple throughout the day. The most productive approach right now is to switch fly patterns frequently during hatches — the Crooked’s educated trout are not afraid to reject a pattern after a few drifts.
Top Fly Recommendations
- Elk Hair Caddis (#14–16, tan or black) — The go-to dry fly right now. Match the size of naturals you see in the air. Fish it with confidence during afternoon hatches.
- Parachute Adams (#16–18) — A versatile catcher during mixed PMD and caddis windows. High-visibility wing makes it easy to track in riffles.
- Zebra Midge (#18–22, black/silver) — A consistent sub-surface producer on the Crooked year-round. Fish it deep on a tight-line nymph rig during slower periods between hatches.
- Pheasant Tail Nymph (#14–18) — PMD nymph imitation that covers multiple hatches. Add a small bead head for extra depth in deeper runs.
- Woolly Bugger (#8–10, olive or black) — Swing one through the deeper pools for larger browns in the lower canyon section. Dead-drift it during off-hatch periods for a streamer alternative.
- Copper John (#16–18) — High-density attractor nymph that punches through fast water to where the bigger fish hold.
Best Access Points
The prime fly fishing water runs from Bowman Dam downstream approximately 8–10 miles toward Crooked River Ranch and Terrebonne. Key access points include the BLM parking area immediately below Bowman Dam, Lone Pine (mile marker ~8), and the lower canyon trail access near Milepost 12. This stretch offers a mix of wading water and canyon-wall scrambling. The upper few miles near the dam fish best in the morning before hatch activity picks up.
Hazards & Reminders
Rattlesnakes are active on the rocky canyon banks in July — watch where you step and place your hands. The trail in the lower canyon can be rugged; wear appropriate footwear and carry water. Prineville Reservoir is well below 50% capacity this summer, so Bowman Dam releases are being managed conservatively. Monitor USGS gauge 14087400 for sudden flow changes. Current ODFW regulations allow artificial lures and flies only with catch-and-release for trout in most of this section — verify current regs before you go.
