The lake is man-made, created by damming the Turtle Creek to provide local water and recreational opportunities.
The park maintains a dedicated 18-hole championship golf course that utilizes the uneven topography near the lake.
The site hosts a unique 'Lakefest' event annually, which historically features fireworks and live entertainment.
The lake depth varies significantly, with some sections managed specifically for diverse freshwater fish habitats.
Sullivan County Park & Lake is a 450-acre facility centered around a 468-acre man-made lake located in southwestern Indiana. The park provides extensive waterfront access for boating, fishing, and swimming in designated areas. It features over 200 campsites equipped with varying levels of utility hookups, alongside several rental cabins. Recreational amenities include an 18-hole golf course, basketball courts, and multiple playgrounds. An extensive network of walking trails winds through the forested sections of the park. The grounds are managed by the Sullivan County Park and Lake Board to support both day-use visitors and long-term campers.
The elevated overlook near the dam provides the widest panoramic view of the lake and surrounding forest canopy.
Book campsites or cabins well in advance during peak summer months, as these fill up quickly.
Bring your own fishing gear if you plan to utilize the lake, as rentals are not always available on-site.
Check local water quality reports before swimming, as conditions can fluctuate based on seasonal rainfall.
Do not attempt to swim outside of designated beach or swimming areas, as lake depths and currents can be unpredictable.
Camping facilities are seasonal, typically opening in the spring and closing in late autumn; the park grounds remain accessible for limited day use throughout the year.
Observe all posted water safety and 'no wake' zones; carry out all trash to maintain park cleanliness.
