Crooked River Report — May 13, 2026: Mother's Day Caddis in Full Swing
Elk Hair Caddis, Parachute Adams, Pheasant Tail Nymph, Zebra Midge, Copper John, Woolly Bugger
Current Conditions — May 13, 2026
The Crooked River below Bowman Dam is delivering some of Central Oregon's finest spring dry-fly fishing right now. The Mother's Day Caddis hatch is in full swing, with olive caddis in multiple life stages on the water throughout the day. Surface activity is consistent, and the fish — predominantly wild rainbow trout with a healthy population of whitefish — are dialed in to the caddis cycle from mid-morning through afternoon.
Flow & Water Conditions
The USGS gauge 14087400 (below Opal Springs, near Culver) recorded 1,140 CFS this morning at 55°F. It is important context for anglers: this downstream gauge reflects the combined flow of Bowman Dam releases plus the substantial Opal Springs contribution — a natural spring complex that adds several hundred CFS of cold, crystal-clear water. The prime fishing section from Bowman Dam downstream through the upper canyon runs at considerably lower flows (estimated 250–300 CFS based on recent reports), with clear, wadeable water and excellent visibility throughout. A water temperature of 55°F is ideal — trout are active and feeding aggressively. Felt-soled wading boots with studs are strongly recommended; the Crooked's basalt cobble is notoriously slick at any flow.
Hatch Activity
The Mother's Day Caddis (Brachycentrus) has arrived in force and is generating the best dry-fly action of the season. Olive caddis in sizes #14–#16 dominate, with peak activity in late morning through mid-afternoon. The pupa stage is being hammered subsurface — fish in the film and just below it are keyed on the emergers. A bright green egg sac on your caddis pupa patterns has been a notable trigger this week. Blue-Winged Olives (BWOs) are tapering off but still contributing on overcast mornings. Midges remain a consistent producer in the slower, deeper pools at first light.
Top Fly Recommendations
- Elk Hair Caddis (olive/tan, #14–#16) — the classic surface caddis imitation. Dead-drift it through rising fish or give it a gentle skate to trigger a chase.
- Parachute Adams (#14–#16) — covers a wide range of surface activity. Excellent searching dry in broken riffles when you're not sure what the fish want.
- Pheasant Tail Nymph (#14–#18) — a Crooked River staple year-round. Euro-nymph it through the seams and below the riffles for consistent hookups.
- Zebra Midge (#18–#22) — morning gold in the slower, deeper pools. Fish it on 6X tippet under a small indicator or as part of a euro rig.
- Copper John (#14–#16) — a heavier anchor fly to get down into the deeper slots. Pairs beautifully with a Pheasant Tail dropper 12–18 inches behind it.
- Woolly Bugger (olive/black, #8–#10) — swing or slow-strip it through the long glides in early morning before the hatch starts. Larger fish patrol these runs.
Best Access Points
The BLM-managed canyon below Bowman Dam offers outstanding walk-in access. The Chimney Rock trailhead is the most popular entry point, with good bank access to a long stretch of productive water. Additional pull-offs along Lone Pine Road (Hwy 27) provide easy access throughout the canyon. The Crooked River Ranch area near Terrebonne offers lower canyon access closer to the confluence. The upper section — closest to Bowman Dam — sees the most consistent insect activity and the clearest, most predictable water. Bring a 9-foot, 4–5 weight rod, 7.5-foot leader, and step down to 5–6X tippet for technical dry-fly work.
Hazards & Closures
The Crooked River below Bowman Dam is open to fishing year-round with no current closures in effect. The basalt cobble is extremely slick — a wading staff and studded felt soles are not optional on this river. As Bowman Dam releases can fluctuate with irrigation season demands (flows typically increase through May and June), check current USGS gauge conditions before your trip. Rattlesnakes become active in the canyon once temperatures warm — watch your step on rocky outcrops and streamside boulders. A valid Oregon fishing license is required. The Crooked is a gem of Central Oregon — fish it with care and leave it better than you found it.
