Spring Chinook are the target on the Willamette River in April 2026. Capt. David Johnson has been running sand shrimp and eggs behind jumbo jet divers and backtrolling. As the water warms and drops, he is switching to trolling a 360-type flasher with a spinner. In May, watch the tributaries with eggs, bait-wrapped plugs, and coon shrimp, and watch for a possible Columbia reopener.
How is the Willamette River spring Chinook fishing?
Capt. David Johnson has been fishing spring Chinook on the Willamette using sand shrimp and eggs, fished behind jumbo jet divers and backtrolled. The water is starting to warm and drop, which means less current, so he is transitioning toward more trolling as April continues.
What presentation works as the Willamette warms up?
Trolling. David says most anglers will switch to a 360-type flasher with a spinner, and possibly a shrimp behind it, as current drops. In warmer water, spinners are what people will be running for the rest of the month and into May.
Where do the fish move in May on the Willamette system?
Into the tributaries. As those rivers warm, fish push up and the fishery shifts back to eggs, bait-wrapped plugs, and coon shrimp. David lists those as the three main baits used in the tributaries once the spring fish start moving in.
Could the Columbia River reopen in May?
Possibly. David says to watch for a Columbia reopener if the dam counts are good or fewer fish were caught in April than expected. If it reopens, it would be prime time, fished as an anchor fishery with plugs or a troll fishery with herring.
