Crooked River Fishing Report — July 11, 2026

Below Bowman Dam | Terrebonne / Crooked River Ranch Area

Current Conditions at a Glance: Flow 1,200 cfs (USGS Gauge #14087400, below Opal Springs) | Water Temp 56°F | Clarity: Slightly Off | Conditions: Good

The Crooked River below Bowman Dam is carrying elevated irrigation-season flows at 1,200 cfs — boosted considerably by Opal Springs, which injects a massive volume of cold, crystal-clear groundwater into the system below the dam. While the higher flows change the fishing equation, that cold spring input keeps water temps at a stellar 56°F, making the Crooked one of the coolest tailwaters you'll fish anywhere in Central Oregon this time of year. Oregon Department of Fish & Wildlife confirmed just this week that the Crooked continues to offer excellent angling for wild redband trout and mountain whitefish. Adjust your approach for the big water and you'll be rewarded handsomely.

Hatches & What's Working

At these elevated flows, nymphing subsurface is your most productive game plan. Midges are active year-round on the Crooked, and July is no exception. Rig a Zebra Midge (#18–22) as your point fly and trail a Pheasant Tail Nymph (#16–18) as a dropper — this two-fly setup has been the most consistent producer. Use additional split shot to get down quickly into the deeper runs, as fish are holding tight to the bottom out of the main current push.

A Copper John (#14–16) in red or green is a killer attractor nymph when you want to cover water fast and trigger reaction strikes from aggressive redbands. PMD (Pale Morning Dun) activity is showing up in slower, sheltered pockets in the early afternoon — a Parachute Adams (#16–18) can pick off opportunistic risers in calmer backwater sections. For the streamside edges and undercut banks, swing a Woolly Bugger (#6–8) in black or olive to target larger predatory redbands that push into the shallows when flows move baitfish and crayfish off the bottom.

Best Access Points & Strategy

Focus your efforts in the first 10 miles below Bowman Dam, where fish are most densely concentrated in classic tailwater fashion. The Crooked River National Grassland provides extensive walk-in access along the canyon. Pull-outs along Hwy 27 (Crooked River Hwy) give you quick access to popular wade-fishing sections near Terrebonne and Crooked River Ranch. At 1,200 cfs, target soft-water seams on the inside of bends, large eddies behind boulders, and the slower slack water on river margins — this is where fish stack up out of the main flow. Work slowly and methodically; covering less water more thoroughly will outperform rushing from run to run.

Hazards & Safety Notes

Wading is challenging and potentially dangerous at 1,200 cfs — a wading staff is strongly recommended and cross-channel wading should be avoided entirely. Stick to bank fishing or work the shallow edges with care. Water clarity is slightly off due to elevated flows but remains fishable with good visibility in the upper foot or two of the water column. Rattlesnakes are active throughout the high desert canyon during summer — watch your step in rocky and brushy areas near the bank. No closures currently affecting public access in the Crooked River Ranch or Terrebonne sections.
