Formed by Tacoma Power’s Mayfield Dam on the Cowlitz River, Mayfield Lake stretches for approximately 13 miles, creating a scenic and welcoming destination for outdoor recreation in every season. Forested shorelines, mountain views, and calm waters make the lake especially popular with families, boaters, and anglers looking for a relaxing day outdoors. Multiple parks and access points around the lake offer opportunities for camping, picnicking, swimming, boating, and fishing, with well-maintained facilities that make planning a visit easy.

Fishing is a major draw, with anglers targeting trout, bass, and other warm-water species, while paddlers and motorized boaters enjoy the lake’s generally smooth conditions. For a closer look at the area’s hydroelectric history, visitors can access a viewpoint overlooking Mayfield Dam from Highway 12 via Gershick Road at Silver Creek, then follow Hydro Lane south. The overlook provides an impressive perspective on the dam and the role it plays in regional power generation and river management.
