About
Potholes State Park is a 775-acre camping park with 6,000 feet of freshwater shoreline on O'Sullivan Reservoir that welcomes boaters, fishers, and swimmers. This body of water is often confused with the Pothole Lakes themselves, which are a 30- to 45-minute drive from the park. The terrain is desert with freshwater marshes.
