Rock Creek Lake State Recreation Area, north of Parks, has 54 acres of land around a 50-acre spring-fed lake. All boats are allowed at no-wake speed (5 mph), with one ramp and dock. Anglers catch channel catfish, largemouth bass, redear sunfish and yellow perch, and rainbow trout are stocked seasonally; live baitfish are not allowed. There are 23 primitive campsites without electricity or drinking water, vault toilets, picnic tables, grills and a playground; pay at the iron ranger in cash or check. A park entry permit is required. The Rock Creek State Fish Hatchery is two miles upstream.
