The Water Mine is a waterpark contained within Lake Fairfax Park which has over an acre of water play activities surrounded by a lazy river called Rattlesnake River with a 2.5-mile-per-hour (4.0 km/h) current.

Lake Fairfax was originally developed as a private recreation facility in the late 1950s - early 1960s by local developer and entrepreneur Mack Slye "Jack" Crippen Jr, the former owner of Roer's Safari, now known as NOVA Wild.

In 1965, James S. Mott and his wife Marguerite were denied entry to the park because they were black.
