About This Water
High desert tailwater with excellent year-round fishing. Wild rainbow trout in canyon setting.
Fishing Recommendations
The Crooked River is arguably one of the most productive and beloved "tailwater" fisheries in the Pacific Northwest. Located just east of Terrebonne and Prineville, Oregon, it flows through a stunning basalt canyon characterized by towering orange cliffs and high-desert sagebrush.
As an expert guide, I can tell you that the Crooked is often called a "numbers" fishery. While the fish aren't always trophies, the sheer density of wild trout per mile is staggering—often exceeding 3,000 fish per mile. It is a technical yet rewarding river that provides year-round opportunities when other rivers are blown out or frozen.
🎣 Location Overview
The primary fly fishing section of the Crooked River is the 8-mile stretch below Bowman Dam (Prineville Reservoir). This is a classic tailwater, meaning the water temperature stays relatively stable year-round, creating a nutrient-rich environment for insects.
What makes it special is its accessibility and the "intimate" feel of the water. It’s a small to medium-sized river, rarely requiring long casts, making it an excellent classroom for beginners but a tactical challenge for experts. The water is often slightly "milky" or turbid due to the reservoir, which actually helps anglers get closer to the fish without spooking them.
🐟 Target Species & Behavior
Interior Redband Rainbow Trout
The star of the show. These are wild, native fish known for their brilliant crimson stripe and incredible fighting spirit.
- Behavior: They hold in the "seams" between fast and slow water. They are notorious for sitting in very shallow, oxygenated riffles during the summer and dropping into deeper slots during the winter.
- Feeding: They are opportunistic but can be size-selective. They feed heavily on midges, scuds, and small mayflies.
Mountain Whitefish
Often overlooked but incredibly abundant. They occupy the deeper pools and provide great action when the trout are being finicky.
Brown Trout
While less common than the Redbands in the tailwater section, there are some beautiful Browns found further downstream toward the Lower Crooked. They are predatory and prefer structure and undercut banks.
📅 Best Times to Fish
The Crooked is one of the few places in Oregon where you can find a solid dry fly hatch in January.
- Spring (March – May): Prime time. This is the window for the famous Blue Winged Olive (BWO) hatches.
- Summer (June – August): Excellent, but watch the CFS (flow rates). High flows for irrigation can make wading difficult. Look for Caddis in the evenings.
- Fall (September – November): My personal favorite. The flows drop, the crowds thin, and the BWO and Mahogany Dun hatches are prolific.
- Winter (December – February): The "Midge Window." On sunny afternoons, you can find fish rising to tiny midges even in the snow.
Best Times of Day: 10:00 AM to 3:00 PM in the winter/spring; early morning and late evening (the "magic hour") in the heat of summer.
🪰 Recommended Flies & Techniques
Nymphing (The Bread and Butter)
90% of the fish here are caught sub-surface. European Nymphing (Tight-line) is incredibly effective here.
- Zebra Midge (Red, Black, Olive): Sizes 18-22.
- Ray Charles or Scuds: (Grey, Tan): Sizes 16-18.
- Micro Mayfly: Sizes 18-20.
- Two-Bit Hooker: Sizes 18-20.
Dry Flies
When the hatch is on, the fish will stack up in the tailouts of pools.
- BWO Sparkle Dun: Sizes 18-20.
- Parachute Adams: Sizes 18-22.
- Elk Hair Caddis: Sizes 16-18 (Summer evenings).
- Griffith’s Gnat: Sizes 20-22 (Winter midges).
Presentation Tips
- Size Matters: If you aren't catching fish, go smaller. A size 20 instead of an 18 often makes the difference.
- Light Tippet: Use 5X or 6X fluorocarbon for nymphing. The fish can be leader-shy in the slower pools.
- Short Leashes: Since the river is shallow, use a small "yarn" indicator or a "dry-dropper" rig to avoid spooking fish with a heavy bobber.
💡 Pro Tips & Local Knowledge
- Check the Flows: Before leaving, check the Bureau of Reclamation (BOR) website. Ideal fishing flows are between 150 and 300 CFS. Above 500 CFS, the river becomes difficult to wade and dangerous.
- The "Scud Shuffe" (Accidental): As you wade, you will naturally kick up scuds and sowbugs. Often, the best fishing is directly downstream from where you just walked.
- Look in the "Thin" Water: During the BWO hatch, don't just fish the deep holes. Native Redbands will move into water so shallow their back fins are almost sticking out to intercept emerging duns.
- Stealth: Because the canyon walls are high, your shadow can easily spook a pool. Fish with the sun in your face when possible to keep your shadow behind you.
⚠️ Important Information
Access
- Access is incredible. The Chimney Rock Segment of the Crooked River National Wild and Scenic River offers numerous BLM campgrounds (like Poison Butte, Chimney Rock, and Stillwater) with easy parking and paths down to the water.
Regulations
- Barbless Hooks Only: Required to protect the wild trout.
- Catch and Release: While some sections allow harvest, it is highly encouraged to release all wild Redbands to maintain the fishery.
- License: An Oregon Angling License is required.
Special Considerations
- Rattlesnakes: This is high-desert country. During the summer, keep an eye out for rattlesnakes near the rocky banks and tall grass.
- Cell Service: It is non-existent in the canyon. Download your maps and tell someone where you are going.
The Crooked River is a gem of Central Oregon. Respect the fish, enjoy the canyon views, and keep your flies small!
