About

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.

Facilities

Dam East-McNair Campground has one reservable group picnic shelter that can accommodate up to 80 people, as well as 47 individual campsites (1-32 located within the North and South loops of the campground, 33-47 located within the East Spillway loop below the main dam) that are available to reserve from the current day up to six months in advance. 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

Carlyle Lake is home to an array of wildlife that can be seen throughout the year. Its waters and shores are a resting spot for migratory waterfowl and other birds. There are six established Watchable Wildlife Sites with viewing towers open to the public around the lake.
