Crooked River Fishing Report – October 27, 2026: Technical Midge Fishing Below Bowman Dam

The Crooked River below Bowman Dam has settled into its classic late-October low-water pattern. USGS gauge 14087400 (below Opal Springs, near Culver) reads 1,180 CFS and 54°F — this station captures flow after the significant Opal Springs inflow. The popular fly fishing reach from Bowman Dam down through Crooked River Ranch and toward Terrebonne is flowing around 35 CFS, which is low but perfectly fishable with adjusted tactics. What the Crooked lacks in volume it more than makes up for in clarity — the water is running crystal clear with that signature green-tinted tailwater hue, and trout are visible in every run and eddy.

Active Hatches

It’s midge season on the Crooked. Expect consistent Chironomid activity throughout the morning into early afternoon — size #20–24 is the target range. October Caddis nymphs remain present in the substrate and fish will take larger, dark nymph patterns during their drift phase. Notably, whitefish are actively spawning right now, and the dislodged eggs drifting downstream are putting trout into feeding lanes — a small egg pattern in pink or orange can be deadly fished tight to the bottom below spawning redds. PMD (Pale Morning Dun) activity has wound down from its fall peak but a few fish are still responding to small yellow-olive dries on warm afternoons.

Top Flies

The Crooked’s low-water conditions demand small flies, light tippet (5X–6X), and deliberate, drag-free presentations. The standout rig is a dry-dropper setup: float a Chubby Chernobyl (#14) up top as your indicator and drop a Zebra Midge (#20–22) 18–24 inches below — this combination covers the midge hatch while keeping you off the bottom in the shallow flows. A Pheasant Tail Nymph (#16–18) is the classic all-day producer, especially in the broken-water riffles and pocket water. A small Copper John in red or copper rounds out a two-nymph rig beautifully. When fish are rising to the midge hatch, switch to a Parachute Adams (#20–22) in grey or olive for a versatile surface pattern that covers both BWO and midge emerger situations. For those who want to swing meat through the deeper pockets and undercut banks, a black Woolly Bugger (#10) will draw the largest fish out of hiding, particularly in low-light conditions. The Elk Hair Caddis (#14–16) in tan or orange is worth carrying for any afternoon caddis activity.

Best Access Points

Lone Pine Campground (ODFW) is the go-to starting point, offering streamside access to excellent riffles and runs with reliable fish populations. The Big Bend Campground area puts you into productive pocket water and seams. Chimney Rock is a local favorite for sight-fishing to Redband trout in clear glassy runs. The string of pullouts along Lower Bridge Road allows you to hop between sections until you find active risers — a solid strategy on low-water days when fish spread across the river.

Hazards & Notes

At ~35 CFS, crossings are straightforward, but the Crooked’s basalt substrate is notoriously slippery — felt soles or studded wading boots are strongly recommended. Rattlesnakes are less active in late October but can still be encountered on warm afternoons; watch your step on rocky banks and ledges. Respect all posted private property along the river corridor. The Crooked River is catch-and-release only for trout in the reach below Bowman Dam — handle fish quickly and wet your hands before touching them. The cool 54°F water means strong, healthy fish that deserve a careful release.
