Formed by Tacoma Power’s Mayfield Dam on the Cowlitz River, Mayfield Lake stretches 13 miles and offers a scenic setting for outdoor recreation year-round. Multiple parks along the shoreline provide access for camping, picnicking, swimming, boating, and fishing, making it a favorite destination for families and outdoor enthusiasts. Anglers enjoy opportunities for trout and bass, while boaters appreciate the lake’s calm waters. For an up-close view of the impressive hydroelectric dam, access the viewpoint from Highway 12 via Gershick Road at Silver Creek, then drive south to Hydro Lane.
