The Willamette River is one of Oregon’s premier fishing destinations, flowing 187 miles northward through the Willamette Valley from its origins near Eugene to its confluence with the Columbia River in Portland. It’s the largest river entirely within Oregon, draining a basin of roughly 11,500 square miles. For anglers, its defining feature is accessibility: the Willamette passes through Portland, Salem, Corvallis, and Eugene, putting quality salmon, steelhead, sturgeon, and bass fishing within easy reach of most of the state’s population. The spring chinook run, in particular, draws thousands of anglers to the lower river each year and is considered one of the best in the Pacific Northwest.
Spring Chinook Salmon: The Main Event
The Willamette River’s spring chinook run is the fishery that defines the river for most anglers. Hatchery spring chinook begin entering the lower Willamette in late winter, and the fishery typically runs from March through June. In the lower river (Portland Harbor, Multnomah Channel, and down toward the Columbia confluence), fishing is best from March through mid-May. As water temperatures rise, the fish push upstream — by May and June, the action shifts to the Oregon City area below Willamette Falls, and then into the upper valley tributaries (McKenzie, Santiam) where fishing can extend into July.
Spring chinook are widely considered the best-eating salmon in the Pacific Northwest due to their high fat content. The 2025 preseason forecast called for roughly 50,000 spring chinook returning to the Willamette — about one-fifth of the total Columbia River spring chinook run. Run size varies significantly from year to year, so check the ODFW forecast before planning your trip.
Regulations: Only hatchery fish (adipose fin clipped) may be kept. The daily bag limit is two hatchery salmonids (chinook or steelhead) per day in the lower Willamette. A valid Oregon angling license, harvest tag, and Columbia River Basin Endorsement are required for salmon and steelhead fishing anywhere in the Columbia River watershed, including the Willamette. Regulations change in-season — always check the ODFW regulation updates page before fishing.
Where to Fish for Spring Chinook
Multnomah Channel / Head of Channel: The area just below the St. Johns Bridge where the Multnomah Channel branches off the Willamette is one of the most popular spring chinook spots on the river. Migrating fish congregate here as they move upstream. Trolling is the dominant technique — herring (both cut plug and whole bait) is the standard offering. Fish depth varies: 15 to 25 feet is productive in the channel area, while deeper water (40 to 80 feet) in the shipping channels and on the Sauvie Island side can produce when fish are holding deeper. Most anglers find the sweet spot at 20 to 30 feet.
Portland Harbor to Milwaukie: The stretch from the downtown Portland waterfront south to Milwaukie produces well through March and April. Trolling with herring, spinners, or plugs covers water efficiently. Both cut-plug herring and whole herring work; on any given day the fish may prefer one over the other, so rigging rods with both is a common strategy. Green-label herring is the standard spring size.
Oregon City (below Willamette Falls): By mid-April to May, fish stack up below Willamette Falls as they wait to ascend. Anchor fishing with eggs (cured roe), prawns, and plugs is the primary technique here, though trolling still works in some spots. This area produces well into June in most years, though rising water temperatures can end the fishery earlier in warm springs.
Tidal influence: In the lower river, fishing is often best around tide changes — particularly the hour before and after an incoming tide, which pushes fish upstream.
Other Salmon and Steelhead
Coho salmon: The Willamette has a moderate coho fishery, primarily above Willamette Falls. These fish originated as hatchery stocks that now spawn naturally in several valley tributaries, including the Santiam River system. The best coho fishing occurs from September through November, with anglers casting or trolling lures near tributary mouths (Tualatin, Santiam). Below the falls, coho must be hatchery-marked (fin-clipped) to keep. Above the falls, fin clips are not required for retention because the fish descend from hatchery-origin populations.
Steelhead: Both winter and summer steelhead runs pass through the Willamette, though most steelhead fishing takes place in the tributaries rather than the mainstem. The Clackamas River mouth area near its confluence with the Willamette attracts a small but dedicated group of bank anglers targeting both runs. In the upper valley, the section through Eugene offers decent summer steelhead fishing from late spring through early fall, with hatchery smolts planted there. Steelhead must be hatchery-marked (adipose fin removed) to keep. Steelhead are also frequently caught incidentally by anglers fishing for chinook and shad in the lower river.
Sturgeon
The Willamette River holds a significant population of white sturgeon, and sturgeon fishing provides action when other fisheries are slow — particularly during high, muddy water in fall and winter, when salmon fishing stalls. Sturgeon fishing is also productive in Multnomah Channel. Fish range from juveniles of a few feet to occasional giants exceeding eight feet, though most catches are in the 3- to 5-foot range.
Sturgeon regulations are complex and change frequently. Retention fisheries are opened on specific dates and in specific river sections, with annual bag limits (currently two fish per year statewide, with strict size windows). Most sturgeon fishing on the Willamette is catch-and-release. Check ODFW for current retention seasons and size limits before targeting sturgeon — these rules are updated in-season and cannot be summarized reliably in a static guide.
Warmwater Species: Bass, Walleye, and Panfish
The Willamette Valley is some of the best smallmouth bass water in Oregon, a fact that many visiting anglers overlook in favor of salmon. Smallmouth bass are found throughout the mainstem and in many tributaries, with the stretch from Corvallis to Salem being particularly productive. Largemouth bass inhabit slower backwaters, sloughs, and off-channel areas. There’s no size or bag limit on bass in the Willamette Zone.
Channel catfish, bluegill, crappie, and other panfish are common in slower stretches and provide year-round fishing opportunities. Walleye are also present in the lower Willamette and Multnomah Channel, though they receive less attention than in some other Northwest rivers.
Shad
American shad run the Willamette in late spring and early summer (May through July), primarily in the lower river below Willamette Falls. Shad fishing is fast-paced, light-tackle fun — small jigs and darts fished in current are the standard technique. There’s no daily bag limit on shad, and they arrive in enormous numbers when the run is on. Many anglers who are on the water for chinook catch shad incidentally.
Access and Logistics
The Willamette is well-served with public boat ramps throughout its length, from the Eugene area to the Portland waterfront. Several boat launches in the Portland metro area provide access to the prime lower-river chinook fishery: Cathedral Park (under the St. Johns Bridge), Willamette Park, and various ramps along the Milwaukie and Oregon City waterfront. The river is also fishable from shore in numerous locations, though bank access to the best salmon water is more limited.
Multiple fishing guide services operate on the lower Willamette during spring chinook season, running both day trips and evening trips. Guided trips are a good option for first-time visitors who want to learn the water — the lower river’s channels, depth contours, and tidal patterns take time to learn independently.
Water conditions fluctuate significantly. The Willamette is rainfall-dependent, and heavy rains in the valley can muddy the river for days, shutting down chinook fishing until it clears. Check river gauge readings (USGS gauges at Portland, Salem, and other locations) before planning a trip. Flows below 3,000 cfs at relevant gauges generally provide fishable conditions for salmon.
License Requirements
To fish the Willamette River, you need a valid Oregon angling license and a harvest tag. For salmon, steelhead, and sturgeon anywhere in the Columbia River watershed (which includes the entire Willamette system), you also need a Columbia River Basin Endorsement. A two-rod validation is available and has been permitted for chinook fishing on the lower Willamette in recent seasons — check current year regulations to confirm. Licenses and endorsements can be purchased online through the ODFW website.
