Crooked River — Below Bowman Dam Fly Fishing Report
Date: June 1, 2026 | Flow: 1,260 cfs (USGS gauge 14087400) | Water Temp: 55°F | Clarity: Off-Color
The Crooked River below Bowman Dam is in full irrigation-season mode as of June 1st, with flows surging to 1,260 cfs — well above the typical spring fishing range of 100–400 cfs. Prineville Reservoir releases ramp up dramatically each year in late May and June to meet downstream irrigation demand, and this year is no exception. The good news: fish are still catchable, but you will need to adjust your strategy, access points, and fly selection to succeed under these challenging high-water conditions.
Current Conditions
USGS gauge 14087400 (below Opal Springs, near Culver) is reading 1,260 cfs this morning, with a water temperature of 55°F. At this flow, the river is significantly elevated — wading is not recommended through most of the standard wade-fishing reaches. Water clarity is off-color, with visibility reduced by the high turbulent flow churning up fine sediment. Fish have pushed to the softer edges: slack water behind boulders, undercut banks, and slow back-eddies along the canyon walls. The cold, dam-regulated temperature of 55°F is still within range for active feeding, particularly for the midge-dependent redband trout this river is famous for.
Hatch Activity
Midge activity persists year-round on the Crooked, even at high flows. Look for rising fish in calmer back-eddies and protected pockets where insects collect. Small Baetis (Blue-Winged Olive) emergences can occur on overcast afternoons in protected sections. High flows suppress most other hatch activity — focus on subsurface techniques and look for any foam lines collecting midge shucks and spent adults.
Top Fly Recommendations
High water calls for weight and presentation adjustments. A Zebra Midge (#18-22, black and chrome) is your best bet — dead-drift it deep through any soft pocket water and eddies you can identify. Pair it with a Pheasant Tail Nymph (#16-18) on a two-fly nymph rig with ample split shot to get down in the fast water. A Copper John (#14-16) fished on a tight-line nymphing setup can reach fish holding in compressed seams. In the deeper, slower runs and back-eddies, swing a small Woolly Bugger (black or olive, #8-10) — high water triggers predatory behavior in larger redsides and the movement of a streamer can be very effective. If you spot fish rising in protected eddies, a Parachute Adams (#16-18) drifted naturally in the calm water may draw strikes.
Best Access Points Under High Flows
- Lower Crooked River Ranch Road (BLM access): Drive north from Terrebonne on US-97, then west on Lower Bridge Road. Access points closer to the canyon rim allow you to spot and target fish holding in protected bank water without wading deep.
- Chimney Rock Trailhead: Drive 12 miles south from Prineville on OR-27. The canyon walls create protected pockets on the inside bends — target these with reach casts from the bank.
- Mile Marker 8 area: Closer to Prineville, where the canyon is slightly less confined and bank access is easier. Look for the deepest, slowest runs — fish stack up here at high flows.
Hazards and Important Notes
Do not attempt to wade the main channel at 1,260 cfs — the Crooked's rocky substrate and powerful current make wading extremely dangerous at elevated flows. Polarized glasses are essential for spotting fish in off-color water. Monitor Prineville Reservoir outflow levels at USGS gauge 14087400 — flows should begin dropping as irrigation demand levels off in mid-to-late June, which will bring the river back into prime wading conditions. USGS flow and temperature data are provisional and subject to revision.
