Created in 1967, the 26,000-acre lake is recognized as one of the nation's top ten inland sailing lakes and hosts several races and regattas. The 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, and there are six established Watchable Wildlife Sites with viewing towers open to the public around the lake.
The Carlyle Lake Visitor Center, located in the Dam West Recreation Area, has information available and nature exhibits on display, including a 215-gallon aquarium with native fish.
Boulder Day Use Area provides fun both on the water and on shore. A boat ramp and courtesy dock are provided, 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 is an on-site playground and plenty of wide open space for children to play. A multi-use biking and walking trail is located a short drive away at the main dam.
