About Clackamas River

The Clackamas is Portland's home river, and it lives a double life. It falls 83 miles out of the Mount Hood National Forest, pools behind three PGE dams above Estacada, and then runs the last 20-odd miles through the suburbs to meet the Willamette at Oregon City. That split is the whole story. Above North Fork Reservoir it's a clear, boulder-strewn mountain freestone full of wild cutthroat, rainbows, and mountain whitefish, where the rule is fly-angling and catch-and-release only. Below River Mill Dam it's an anadromous river — one of the closest genuine winter and summer steelhead and spring Chinook fisheries to a major West Coast city. Roughly half its length carries a National Wild and Scenic designation, which is unusual for a river you can reach from downtown in under an hour.

For the swing-and-drift crowd, the lower river is the draw. Winter steelhead show from mid-December, the wild fish push through late January into May, and a smaller summer run overlaps March into June; spring Chinook arrive in April and coho light up a fall fishery from September. The lower river fishes best from a boat — the classic runs are the drift-boat and jet-sled floats between Milo McIver, Feldheimer, Barton, Carver, and Riverside, with Barton-to-Carver the most popular and most crowded stretch. The Estacada gauge is the number everyone watches: locals like the river between about 10 and 13 feet of stage, and it blows out and browns up fast after Cascade rain. Up top, the trout water around Three Lynx and Big Bottom is genuinely good, wadeable pocket water that sees a fraction of the pressure.

The trade-offs are honest. The lower river is busy — jet boats run up from Carver, bank anglers stack on the popular runs, and it fishes as much a put-and-take hatchery fishery as a fly one. Clarity is weather-dependent; a warm winter storm can take it out for days. And this is a river with a real conservation history — wild winter steelhead and spring Chinook here are ESA-listed, PGE's relicensed dams now pass fish, and the fly-only C&R rule above the reservoir exists for a reason. Come for the convenience and the shot at a metro-area steelhead; don't expect solitude on the lower runs.

Species

  • Steelhead (winter run)
    Primary · Dec-May · 6-12 lb

    The signature fishery on the lower river. Hatchery fish show from mid-December; wild winter steelhead peak February through April and are ESA-listed. Hatchery (adipose-clipped) steelhead are open all year; wild-steelhead retention is allowed only July 1–August 31, otherwise release. Swung flies and side-drifting from a boat.

  • Steelhead (summer-run)
    Common · Mar-Jun · 4-9 lb

    A hatchery-supported summer run that overlaps the tail of the winter fish. Smaller wets and skated dries in lower, clearer flows.

  • Chinook Salmon (spring run)
    Common · Apr-Jul · 10-25 lb

    Springers arrive as early as April and peak May–June. Only adipose-clipped hatchery fish may be retained; wild spring Chinook are ESA-listed. A big-water fishery on the lower river.

  • Coho Salmon
    Common · Sep-Nov · 6-12 lb

    Fall coho (silver) salmon can put on a strong fall fishery from September, a mix of hatchery and wild fish.

  • Chinook Salmon (fall)
    Present · Sep-Oct · 10-20 lb

    A smaller run than the spring Chinook, secondary to coho in the fall.

  • Coastal Cutthroat Trout
    Primary · May-Oct · 8-14"

    The dominant wild trout in the upper river above North Fork Reservoir — clear-water pocket fishing on attractor dries and nymphs. Fly-angling and catch-and-release only up top.

  • Rainbow Trout (wild)
    Common · May-Oct · 8-16"

    Wild rainbows share the upper basin with cutthroat, mainstem and tributaries; some juvenile steelhead are present. Best on summer baseflow in the freestone reach above the reservoirs.

  • Mountain Whitefish
    Present · Year-round · 8-16"

    Common in the upper river; a nymph bycatch that's fun on light tackle and a reliable cold-season target.

Sections

4 reaches

River Mill Dam to Barton (McIver / Feldheimer)

FloatSteelhead · Salmon

The uppermost anadromous water, below the PGE dams — riffles, gravel bars, and steelhead runs. Milo McIver State Park sits just below River Mill Dam with upper and lower ramps; Feldheimer is a drift-boat-only gravel launch. A McIver-to-Barton drift is an easy 3–4 hour float and less crowded because of the longer drive to Estacada.

Best for: Winter and summer steelhead and spring Chinook — swinging, side-drifting, and nymphing runs from a drift boat, with some bank and wade access at the parks.

Barton to Carver

FloatSteelhead · Salmon

The most popular float on the river — classic side-drifting and swing water with gravel bars above Carver, and the most crowded, with jet boats running up from the Carver ramp. Both put-in (Barton Park) and take-out (Carver) are developed county-park ramps.

Best for: The signature Clackamas run for winter and summer steelhead, spring Chinook, and fall coho salmon — side-drifting, swung flies, and plugs. Drift boats favored at lower flows.

Carver to the Mouth (Riverside / Clackamette)

FloatSteelhead · Salmon

The lowest reach — the longest runs on the river and the best side-drifting water, with fewer houses than the reaches above. It ends at the Willamette confluence at Clackamette Park in Oregon City, and two-rod validation is allowed downstream of the Highway 99E bridge.

Best for: Winter and summer steelhead, spring Chinook, and fall coho salmon on long side-drifting runs — the closest steelhead water to Portland proper.

Upper Clackamas — Big Bottom to North Fork Reservoir

WadeCutthroat · Rainbow Trout · Whitefish

Clear mountain freestone through the Mount Hood National Forest — boulder pocket water, riffles, and pools, much of it National Wild and Scenic. Highway 224 parallels the river, with access at Forest Service campgrounds and pullouts around Big Bottom, Riverside, and Three Lynx. This is the wild-trout river: fly-angling and catch-and-release only above North Fork Reservoir.

Best for: Wild coastal cutthroat trout, rainbow trout, and mountain whitefish on attractor dries and stonefly nymphs — low pressure relative to the lower river.

Best seasons

Winter and spring (February–May) is prime for steelhead — wild winter fish peak February through April in cold, cleared water. Spring (April–June) adds Chinook; fall (September–October) brings coho on the lower river plus October Caddis on the upper trout reach; summer (June–September) is the upper-river dry-fly trout window on low, clear baseflow. The lower river is watched by stage at the Estacada gauge — locals target roughly 10–13 feet, and below about 12 feet favors drift boats over jet sleds. Warm Cascade rain spikes and browns the river fast; when the Estacada stage climbs well above 13 feet and the water colors, give it a few days. Summer water temps climb into the upper teens Celsius in the lower river, warm enough that summer trout fishing and low-water ethics belong on the cooler upper reaches.

Regulations

The Clackamas is an anadromous river with an ESA conservation history: wild winter steelhead and spring Chinook are listed, so retention is hatchery-only for most of the year and the upper river above North Fork Reservoir is fly-angling and catch-and-release only. Falls under the 2026 Oregon Sport Fishing Regulations, Willamette Zone — verify current rules before fishing, as anadromous seasons change in-season.

  • Oregon angling license required for anglers 12 and up; a Combined Angling Tag is required to fish for or retain salmon, steelhead, or sturgeon.
  • Above North Fork Reservoir the upper Clackamas is fly-angling and catch-and-release only; wild trout are catch-and-release, general trout season open roughly May 22–October 31.
  • Hatchery (adipose-clipped) steelhead and salmon open all year; combined daily limit of 3 hatchery salmon or hatchery steelhead. Wild steelhead may be retained only July 1–August 31, otherwise release.
  • No angling from a floating device between River Mill Dam and the ODFW markers about 100 ft above the Clackamas Hatchery water intake.
  • Two-rod validation permitted downstream of the Highway 99E bridge. Bait is allowed in the lower river.

Wild winter steelhead and spring Chinook are ESA-listed; PGE's relicensed dams now pass fish. Confirm in-season salmon and steelhead rules in the current Willamette Zone booklet before you fish.

Getting there

Estacada, OR

30-45 min from downtown Portland to the lower river (Carver/Barton); ~45 min-1 hr to Estacada; ~1.5-2 hr up Hwy 224 to the upper trout water

Fly shops

  • Royal Treatment Fly FishingWest Linn
  • Northwest Fly Fishing OutfittersPortland

Camping: Milo McIver State Park has camping and boat ramps just below River Mill Dam. Barton, Carver, and Riverside county parks offer day-use and ramps on the lower river; Forest Service campgrounds line Hwy 224 in the upper canyon (Three Lynx, Big Bottom, Riverside). Most anglers day-trip from Portland, Oregon City, or Estacada — there are no fishing lodges on this metro river.

County and state park day-use or launch fees apply at Barton, Carver, and Milo McIver; a NW Forest Pass is needed at some upper-canyon FS sites. PDX airport is ~30-45 min from the lower river.
