Lake Hudson State Recreation Area in Lenawee County, Michigan, is a state park established in 1979 around the 502-acre Lake Hudson reservoir, formed when an earthen dam joined the former Bear, Covell, and Haley lakes along Bear Creek. Known for quiet boating under a lakewide no-wake rule and for fishing, it supports species including walleye, muskellunge, crappie, bluegill, catfish, bass, pumpkinseed, and perch. The park also offers camping, a beach, a boat ramp, hiking, bird watching, photography, geocaching, and seasonal hunting. In 1993 it became the first dark-sky preserve in the United States, protecting natural darkness by limiting light pollution.
