There are few fishing experiences in Oregon that match the electricity of a spring Chinook salmon inhaling a plug or spinner in the Willamette River on a May morning. The air is still cool, the water running green and clear after the spring flush, and when a 25-pound king decides your lure is lunch, the world stops for a few glorious seconds. If you have not made time for this run, it is time to fix that.

Understanding the Willamette Spring Chinook Run

Spring Chinook — locally called springers — begin staging at the mouth of the Willamette in late March and push upriver through June. The peak of the adult run through the lower river typically lands in late April through mid-May. These fish are ocean-bright, loaded with fat, and widely considered the best-eating salmon in the Pacific Northwest. Oregon Department of Fish and Wildlife (ODFW) data consistently shows the Willamette as one of the top spring Chinook fisheries in the state by total angler harvest.

Unlike fall Chinook, springers enter the river with the intent to hold for months before spawning. That means they are actively feeding on a fuller energy budget and far more willing to commit to lures and bait than their fall cousins.

Best Stretches of River to Fish

The most productive Willamette springer water runs from the Columbia confluence at Kelley Point upstream past Oregon City and into the Newberg Pool. Key spots include:

  • Swan Island and the Sellwood Reach: Deep channel water through Portland holds staging fish. Troll or anchor on the downstream faces of structure.
  • Newberg Pool (RM 45-60): Consistently the highest-density holding area during the peak run. Trolling with plugs and spinners is the bread-and-butter approach here.
  • Willamette Falls (Oregon City): Fish stack below the falls waiting for water levels to allow passage. Anchor fishing with back-bounced eggs or sand shrimp can be deadly during high fish counts.
  • Canby Ferry Area (RM 52): Slower inside bends and gravel-bottomed tailouts hold fish that are resting between travel pushes.

Trolling Tactics That Work

Trolling is the dominant technique on the Willamette, and for good reason. It covers water efficiently and keeps your presentation in the strike zone on moving fish. The setup most guides run is simple and proven:

  • Plugs: Brad's Killer Fish and Kwikfish in K15-K16 sizes lead the pack. Wrap the belly hook with a sardine fillet using elastic thread. Colors: chartreuse, orange, and flame red are consistent producers in the Willamette's slightly off-color spring flows.
  • Spinners: Size 5-6 Blue Fox Vibrax in chrome/orange or chartreuse work well at slower trolling speeds of 1.5-2.5 mph over bottom. Run them 40-60 feet behind the boat on 15-20 lb monofilament.
  • Trolling Speed: Target 2.0-2.8 mph over ground for plugs. Speed up slightly in current seams to prevent fouling, slow down in slack water.
  • Depth: Most fish cruise 6-15 feet below the surface. Use a downrigger or inline weight to stay in the zone without hitting bottom.

Anchor Fishing and Back-Bouncing

When fish are stacked, anchoring up and presenting bait to stationary fish can outfish trolling. Rig a 1-2 oz pencil sinker on a dropper loop, with an 18-inch leader to a size 2/0 Gamakatsu hook. Load it with a golf-ball-sized cluster of cured eggs using BorX O Fire cure in natural pink, or a whole sand shrimp. Cast upstream, let it drift to the bottom, and hold on.

Gear and Line Considerations

A medium-heavy 8.5-9.5 foot rod rated for 1/2-2 oz lures paired with a level-wind reel loaded with 20 lb monofilament covers nearly every situation. Maxima Ultragreen is the guide standard. For bait fishing, drop to 15 lb fluoro leaders in clearer water conditions. Bring a net with at least a 28-inch hoop since springers have a habit of looking small until they are beside the boat.

Regulations and Seasons

Always check the current ODFW Sport Fishing Regulations before hitting the water. The Willamette below Willamette Falls has historically been open for spring Chinook from mid-April through May 31, with daily bag limits typically set at two adults per day, ten in possession. Check for any selective gear rules or closed sections as they change year to year based on run strength. A combined angling and Columbia River Basin Endorsement is required.

Final Word

Spring Chinook on the Willamette is a genuine bucket-list fishery that most Oregon anglers have within an hour of their front door. The run is finite, usually 6 to 8 weeks at its best, so pick a few good days in May, get on the water early, and put some bright kings in the box. There is nothing in the freezer that tastes better.
