From the official listing

Overview Dam East-McNair Campground is situated on the southern shore of Carlyle Lake, a prime getaway for city-dwellers and families. Located 50 miles east of St. Louis, the area offers the peaceful retreat of a small town combined with the grandeur of Illinois' largest man-made lake.

Recreation The area provides fun both on the water and on shore. Boat ramps and courtesy docks are located nearby, and the vast lake allows for plenty of water sports. Fishing is a popular pastime, and the lake offers year-round varieties of fish such as bluegill, crappie, channel catfish, flathead catfish, white bass, largemouth bass, freshwater drum, carp and walleye. There are multiple playgrounds on-site, as well as a swimming beach. A multi-use biking and walking trail is located a short distance away at the dam.

The facility also provides a swimming beach, bathhouses and laundry facilities. McNair has a nature trail and a multi-use trail, and is connected to the Dam East facilities.

Natural Features Created in 1967, the 26,000-acre lake is recognized as one of the nation's top ten inland sailing lakes and hosts several annual races and regattas.

There are six established Watchable Wildlife Sites with viewing towers open to the public around the lake. Contact Info For facility specific information, please call (618) 594-2484.
