Crooked River Fishing Report – May 16, 2026: Mother’s Day Caddis Hatch in Full Swing
Elk Hair Caddis, Parachute Adams, Zebra Midge, Pheasant Tail Nymph, Copper John, Woolly Bugger
Crooked River Conditions — May 16, 2026
Flow: 1,140 cfs (USGS Gauge 14087400, below Opal Springs) | Water Temp: 55°F | Clarity: Clear
The Mother’s Day Caddis hatch has officially taken over the Crooked River, and if you’re a fan of dry fly fishing, this is your moment. Flows are running higher than typical — 1,140 cfs at the gauge below Opal Springs — reflecting the onset of irrigation-season releases from Bowman Dam. The critical thing to know: the section immediately below Bowman Dam sees more moderate flows than the downstream gauge reflects, so focus your efforts in the top 3–4 miles of tailwater for the best wade fishing conditions. Water temperature is a chilly-but-fishable 55°F, and clarity remains excellent thanks to the regulated, spring-fed character of this fishery.
What’s Hatching
Caddis, caddis, and more caddis. The Mother’s Day Caddis (Brachycentrus) hatch is in full swing and fish are responding both subsurface and on top. Look for pods of rising fish in the slower seams and current edges from late morning through late afternoon. Patterns with a bright green egg sac are the standout trigger right now. Midges and small BWO patterns continue to find fish early in the morning before caddis activity peaks, so keep a few in your box for the first hour on the water.
Top Fly Recommendations
From the Bugs & Jugs fly bench:
- Elk Hair Caddis (sizes #14–#16, olive/tan) — the premier dry for the Mother’s Day hatch; go elk hair when fish are on top and committed.
- Parachute Adams (sizes #14–#18) — dead-reliable when trout are sipping a mix of naturals; perfect in the calmer glides where fish have time to inspect.
- Zebra Midge (sizes #18–#22, black/red) — essential for the early morning bite; dead-drift tight to the bottom in flat water near the dam.
- Pheasant Tail Nymph (sizes #14–#18) — pair with a Zebra Midge as a two-fly nymph rig; effective throughout the day in the classic tailwater riffles.
- Copper John (sizes #14–#16, red) — gets down quickly in the faster runs; a consistent producer when fish are holding deep in elevated flows.
- Woolly Bugger (sizes #8–#10, olive/black) — swing through the deeper pools and undercut banks; larger Redbands and whitefish respond well to a swung streamer in off-season high water.
Strategy
Open the morning with a deep nymph rig — Zebra Midge and Pheasant Tail under an indicator, fished tight to the bottom in 3–5 foot runs. As the sun hits the water and caddis start emerging (late morning through early afternoon), transition to a dry-dropper with an Elk Hair Caddis on top and a caddis pupa dropper. When you see consistent risers, drop the dropper and go fully dry. With elevated flows, target the softer water: current seams, inside bends, and slower pockets where fish can hold without burning energy. A swung Woolly Bugger through deeper pools can be a big-fish tactic worth trying on the way out.
Best Access Points
- Below Bowman Dam (Bowman Dam Rd / end of Juniper Canyon Rd) — the prime tailwater; best wade access and most consistent flows closest to the dam
- Chimney Rock / OR-27 Pullouts — multiple pullouts along the highway south of Prineville; access to classic riffles, runs, and pools
- Crooked River Ranch Area — north of Terrebonne off US-97; access to the lower section where the river opens up
- Lower Crooked River Access (near Culver) — BLM-managed access to the wild and scenic corridor; great water for exploring on foot
Hazards & Closures
Flows are elevated from Bowman Dam irrigation releases — use a wading staff and stay out of fast, deep mid-river channels. The section from the dam downstream is open year-round with no current seasonal closures. Catch-and-release for wild trout is strongly encouraged. Single barbless hooks are required in sections designated as catch-and-release — verify current ODFW regulations before your trip.
