River Overview
The Crooked River continues to deliver exceptional fishing this September, and it remains one of Central Oregon's most reliable fly fishing destinations in the late-summer and early fall window. Today's USGS gauge reading of 1,290 CFS reflects the total discharge below Opal Springs near Culver — the significant cold spring contributions from Opal Springs inflate this number well above the actual flows in the upper fishing section below Bowman Dam, where the canyon stretch near Chimney Rock and Crooked River Ranch typically runs much lighter under current dam releases. The water temperature of 55.4°F is practically perfect for rainbow trout: cold enough to keep fish energized and feeding aggressively, warm enough to trigger excellent afternoon hatches.
Clarity is outstanding throughout the system — the Crooked River's tailwater character and spring-fed flows keep it running gin-clear even as other Oregon rivers show late-summer stress. Wading conditions are comfortable, and the dramatic rimrock canyon that frames this fishery is at its most beautiful in September light. Fishing has been quite good this past week, with both dry-fly and nymph presentations producing results throughout the day.
What's Hatching
Pale Morning Duns (PMDs) remain the headline hatch through early September, peaking mid-morning between 9 AM and noon. Fish are rising consistently during PMD activity, and the spinner fall in the evening adds another productive dry-fly window. Caddis (mostly Brachycentrus and small Hydropsychidae) hatch in the afternoons and are increasingly active as September progresses — expect them to build through the month. Midges are ever-present on the Crooked and provide consistent subsurface and surface action early morning and late afternoon, particularly in flat-water sections. Terrestrials — ants and beetles — supplement the menu on calm, warm afternoons. Hatches are best in the Chimney Rock canyon stretch, where the river slows into glassy pools between riffles.
Top Fly Recommendations
Dry Flies: A size 16–18 Parachute Adams is a near-perfect PMD imitation in a pinch and a reliable all-around producer throughout the day. During caddis activity, switch to a size 14–16 Elk Hair Caddis for visible, buoyant surface presentation. For the midge hatches, a Zebra Midge (size 18–22, black/chrome or red/chrome) fished in the film or just below it is a Crooked River staple — don't leave the truck without a box full.
Nymphs: When fish aren't looking up, go under with a size 14–16 Pheasant Tail Nymph — it imitates PMD nymphs, BWO nymphs, and a half-dozen other naturals the Crooked's trout eat all day long. A size 14–16 Copper John (red or green) is an excellent attractor dropper that adds flash and weight to your rig. For the euro-nymphing crowd, the Crooked River's clear water and visible fish make it an ideal sight-fishing nymph venue.
Best Access Points
The Chimney Rock Recreation Area (BLM) is the premier access corridor — the Lower Crooked River Back Country Byway runs alongside the river for miles, with multiple pullouts for wade-in fishing. Crooked River Ranch provides additional public access and is a great launching point for the upper canyon section closest to Bowman Dam. The Terrebonne area river access points are convenient for day-trippers from Bend or Redmond. The entire stretch is walk-in friendly with well-maintained trails, and the BLM Byway allows easy parking at numerous spots.
Hazards & Regulations
The Crooked River below Bowman Dam is designated catch-and-release only for trout — all rainbow and brown trout must be released unharmed. Barbless hooks are strongly recommended and required in some sections; check current ODFW regulations. Rattlesnakes are active in rocky, sun-warmed areas through September — exercise caution when scrambling on canyon walls. A BLM day-use fee applies at Chimney Rock; bring a Recreation Pass or cash. Water levels in the fishing section below Bowman Dam can change with dam releases — watch for sudden rises.
