Mayfield Lake Park

Click to enlarge.

Mayfield Lake Park offers year-round outdoor recreation along the shores of Mayfield Lake in Lewis County.

The park is a popular destination for swimming, boating, picnicking, and camping, featuring a swimming beach, boat launch, picnic areas, playgrounds, and group-use facilities. The lake is formed by Mayfield Dam, part of Tacoma Power’s hydropower system that generates clean, renewable electricity while supporting public recreation.

Boat launch access, swim areas, and lake levels may vary throughout the year. Get information about day-use and boat launch availability.
