There are over 3,000 acres of water surface on Lake Bruin, and the visitors to Lake Bruin State Park have access to every acre for incomparable freshwater fishing, superb water sports and fine outdoor living. The 53-acre site was originally established in 1928 as a fish hatchery.

Three large fishing piers, a year-round boat launch, and a boat shed for docking make things convenient for the casual or serious fisherman. Rental boats are available. Largemouth bass fishing is popular all year round, but the best months are April, May, June, September and October. Crappie (white perch) are taken around the piers and mats in the early spring. Bluegill fishing is best in the shallower waters at both ends of the lake.

Water sports and pleasure boating are also popular activities at Lake Bruin. A water playground offers a great way to cool off during warm spring and summer months, with a bathhouse located nearby. Lake Bruin's day use area offers picnic tables and barbeque grills situated near the lake and adjacent to two of the fishing piers, restrooms and playground areas. A covered pavilion allows park visitors to enjoy their meals whatever the weather. Most facilities are wheelchair accessible.
