Dam West Spillway 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.
Dam West Spillway 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 and Kaskaskia River offer year-round varieties of fish such as bluegill, crappie, channel catfish, flathead catfish, white bass, largemouth bass, freshwater drum, carp and walleye. There is plenty of open space for children to play and a multi-use biking and walking trail is located a short distance away at the dam.
Dam West Spillway has one reservable group picnic shelter that can accommodate up to 75 people, as well as an accessible fishing pier and several amenities. It is within walking distance of a marina and boat storage facility and connected to the Dam West Day Use Area and Recreation Area, which offers a campground. The Carlyle Municipal Pool is a short drive away.
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.
Not recorded upstream: water hookups, sewer hookups, campfires allowed, fire pits.
