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

Visitors can enjoy swimming, boating, picnicking, and camping, with amenities that include 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.
