Lake Washington - Mercer Island, WA

Lake Washington is the largest natural lake in Western Washington and delivers year-round fishing opportunities in a metropolitan setting. From Mercer Island to Renton, it offers excellent access and deep structure that supports robust populations of trout, bass, and panfish.

Cutthroat trout are a prized target here. These wild fish are available throughout the year and thrive on a diet of smelt and perch. Trolling near drop-offs and ledges around Mercer Island and Rainier Beach with spoons or plugs yields steady results, especially in early spring and late fall.

Smallmouth bass are abundant and active from late spring through early fall. They relate well to riprap, pilings, and underwater humps, especially around the I-90 bridge and south end. Largemouth bass also inhabit shallow bays, though they’re less common.

Yellow perch are widely distributed and especially easy to find in fall and winter. They gather in large schools over deeper water and are readily caught using light tackle. Crappie and sunfish offer additional options during warmer seasons.

Lake Washington also sees seasonal salmon activity, particularly coho, though retention varies by year. Public access is extensive, but weather, boating traffic, and water clarity can affect success.

For anglers willing to adapt to urban conditions, Lake Washington offers rich rewards in a complex and dynamic fishery.
