Crooked River — July 20, 2026
USGS Gauge (Below Opal Springs #14087400) as of 6:00 AM PDT: 1,270 CFS | Water Temp: 56°F | Clarity: Slightly Off
Current Conditions
The Crooked River tailwater is running notably above its typical summer baseline today. The USGS gauge below Opal Springs is reading 1,270 CFS — well above the usual 250–600 CFS range for mid-July — indicating elevated releases from Bowman Dam combined with robust Opal Springs inflows. The good news: water temperature is a superb 56°F, which is ideal for trout activity. The elevated flow is the main challenge today, creating faster, deeper runs throughout the canyon and pushing the river slightly off-color, particularly in the lower reaches.
Anglers willing to adjust their approach can still find productive water. Focus your efforts on the upper section closest to Bowman Dam (the first 3–4 miles of tailwater), where flows will be somewhat more manageable and clarity holds better before Opal Springs joins the main stem. The prime 8-mile corridor from the dam toward Terrebonne and Crooked River Ranch will be wadeable in spots, but expect to do more work to find fishable seams.
Hatches & Fly Recommendations
With the river running higher, sub-surface patterns will outperform dries today. The trout are hunkered in slower water behind boulders and in eddies, feeding efficiently on drifting nymphs and midges. Here is what to throw:
- Zebra Midge (#18–22, black/red thread) — The Crooked's resident rainbow and brown trout are midge specialists year-round. In higher flows, fish a Zebra Midge as a dropper below a larger nymph to cover two feeding zones simultaneously. Sizes 20–22 are your best bet in clear pockets.
- Pheasant Tail Nymph (#14–18) — A dead-drifted Pheasant Tail in the softer seams and eddies along the banks is a go-to in elevated flows. Copper bead versions add flash and sink faster — exactly what you need today to get down in the water column.
- Copper John (#14–16) — Use this as your anchor fly in a two-nymph rig. Its weight gets you to the bottom quickly, and the flash is visible to trout even in slightly off-color water. Red and green are the top color choices for the Crooked.
- Woolly Bugger (#8–10, black or olive) — In higher flows, stripping a Woolly Bugger through the deeper holes and runs can entice the biggest fish of the day. Let it swing on a tight line through the faster water — this mimics a fleeing sculpin or large stonefly nymph.
- Dry Flies (Evening) — If flows moderate through the day and the evening cool-down settles things, look for a caddis rise in slower water after 6 PM. An Elk Hair Caddis (#14–16) or Parachute Adams (#16) can be effective during the evening window near the Crooked River Ranch access.
Best Access Points
Below Bowman Dam (Upper Tailwater): This is your best bet today for cleaner water and more manageable wading. The first few miles below the dam see the least impact from elevated flows and hold excellent concentrations of fish. Access via Juniper Canyon Road. Crooked River Ranch area: The lower canyon access points off Lone Pine Road provide good access to the middle canyon section. The river runs through a stunning basalt gorge here — fish the boulders and structure carefully. Terrebonne/Lower Access: At 1,270 CFS the river will be notably pushy in the lower reaches — experienced waders only in the main channel; safe opportunities exist along softer bank water.
Hazards & Notes
With flows 2–3x above normal, exercise extra caution wading. The Crooked's canyon walls can be slippery even at low water — today that risk is amplified. A wading staff is strongly recommended. The canyon provides some afternoon shade, making midday fishing more comfortable than on the exposed Deschutes. Note that the Crooked River National Grassland is open for public access — no permit required for day use along the main corridor. Watch for rattlesnakes on warm canyon walls and rocky outcroppings.
