About This Access Site
Mayfield Lake County Park offers a well-maintained boat launch facility conveniently located just off Highway 12 near Mossyrock. The park features a paved boat ramp with ample parking for vehicles and trailers, making it an accessible starting point for exploring Mayfield Lake and the Cowlitz River. Day-use amenities include restrooms, picnic areas, and a swimming area, with a 54-space campground available for overnight visitors.

**Important motor restrictions apply:** Only electric motors or gas motors with less than 10 horsepower are permitted on Mayfield Lake, making it ideal for kayakers, canoeists, and small electric-powered boats. For additional launch options, Ike Kinswa State Park is located nearby to the north, and several marinas and resorts around the lake also provide boat launch facilities. The park's combination of reasonable access and family-friendly amenities makes it a solid choice for paddlers and recreational boaters exploring this section of the Cowlitz River system.
