The DNR’s page on Newaygo State Park says it is:
…a 99-site rustic campground, which sits atop 20-foot embankments overlooking the Hardy Dam Pond, a six-mile flooding of the Muskegon River (view on the Absolute Michigan map). The park caters primarily to campers, anglers and recreational boaters. There are several picnic sites overlooking the reservoir for day users. The campground is nestled in oak and poplar forests and is noted for its large, private sites and scenic beauty. There is a 20-30 foot forested buffer between sites, and each site is provided with a picnic table and a fire ring.
