Geiger Lake is a 225-acre freshwater lake located within Paul B. Johnson State Park, 12 miles south of Hattiesburg, Mississippi. The lake, constructed in the mid-1940s using German prisoner of war labor from nearby Camp Shelby, offers diverse paddling opportunities amid a picturesque setting of majestic longleaf and loblolly pines, flowering dogwoods, and ancient oaks.

A boat launch with paved trailer parking is available near the visitor center, and the lake features multiple access points including a sand beach area behind the Visitor Center. The lake is well-suited for paddling, with designated swimming areas and clear boundaries for water skiing zones. Motorized activities, including skiing and pleasure boating, are restricted to the hours of 9:00 a.m. to 7:00 p.m., making early mornings and evenings ideal for peaceful paddling.

The lake is stocked with largemouth bass, bluegill, shellcracker (red ear), crappie, and channel catfish, making it possible to combine paddling with fishing. Annual biological surveys ensure healthy fish populations, and the lake receives regular maintenance including fertilization as needed.

Facilities include lakefront picnic areas with tables positioned near the water's edge, comfort stations near paved parking areas, and a visitor center with an outdoor deck overlooking the lake. Multiple coves and inlets provide opportunities for exploration, while the forested shoreline creates a natural backdrop for wildlife viewing.

Day use permits are required, and fishing licenses are necessary for anglers age 16-65. The lake's relatively small size and protected location within the state park make it suitable for paddlers of various skill levels, though visitors should be aware of motorized boat traffic during permitted hours.
