Cagles Mill Lake, which the park surrounds, was the first flood control project constructed by the U.S. Army Corps of Engineers in Indiana.
The reservoir covers approximately 1,400 acres at normal pool levels.
The park's swimming facility is one of the few designated pool complexes managed within an Indiana state recreation area.
The site sits near the edge of the Mitchell Plateau, influencing the local karst topography and geological features.
The area provides critical habitat for various migrating waterfowl species during spring and fall seasons.
Lieber State Recreation Area is located on the shores of Cagles Mill Lake, Indiana's first flood control reservoir. The park features the Aquatic Center, a large swimming pool complex that serves as a primary recreational draw during the summer months. Visitors have access to a variety of hiking trails that traverse the forested terrain surrounding the lake. The campground offers multiple sites equipped for both tent and RV camping, situated near the water's edge. Boat ramps provide direct access to the lake for fishing, boating, and water sports. The area is managed by the Indiana Department of Natural Resources as part of the Cagles Mill Lake property. The topography is characterized by rolling hills and diverse hardwood forests. The park facilitates wildlife viewing opportunities, particularly for birdwatchers tracking waterfowl and forest species.

Book campsites well in advance, especially for holiday weekends, as they reach capacity quickly.
Bring insect repellent, as the proximity to the lake and forested trails leads to high mosquito activity in warmer months.
Check the official Indiana DNR website for water quality alerts before planning swimming activities.
Do not attempt to swim in Cagles Mill Lake outside of the designated Aquatic Center area due to submerged hazards and fluctuating water levels.
The Aquatic Center is a seasonal facility that typically operates from Memorial Day through Labor Day.
Maintain noise levels during quiet hours in camping areas; pack out all trash to preserve the natural habitat.
