Lake Dolores Waterpark is an abandoned waterpark off Interstate 15 in the Mojave Desert in the community of Newberry Springs, California, United States. The waterpark had operated under numerous names in the past, including Lake Dolores, Rock–A–Hoola Waterpark, and Discovery Waterpark. History Beginnings (1950s–90s) The park was originally designed and built by local businessman Bob Byers for use by his extended family. Lake Dolores was named after Byers' wife. The initial phases of conception, planning and construction took place in the late 1950s and early 1960s. An expanse of arid land on the eastern edge of the Mojave Desert from Interstate 15 was chosen for the project. The area contains underground springs fed by the Mojave Aquifer. Lake Dolores, the body of water, is a man-made lake fed by underground springs. In May 1962 a basic campground adjacent to the small lake was opened to the public. Enthusiasts of motocross and people traveling on Interstate 15 between Los Angeles and Las Vegas gave the campground some business. Over the next 25 years, rides and attractions were added, and the site evolved into a waterpark, which was advertised on television with the slogan "The Fun Spot of The Desert!" The park featured eight identical sixty–degree–angle steel waterslides mounted side by side on a man–made hill. Riders rode on small plastic "floaties" which skimmed across the lagoon when they hit the water at the slide's end. Nearby were two V–shaped waterslides, also roughly long, which were ridden standing up. The slides ended about above the water, shooting the standing rider out of the end like a human cannonball. On the "Zip–Cord" ride, riders hung from a hand–held device attached to a guide wire for approximately at a 30–degree downward angle. At the end of this wire the hand–grip would slam into a blocking mechanism and come to a stop about above the water, with the momentum thrusting the hanging rider forward into the lagoon. In the middle of a smaller adjacent lake were three high diving boards, and three trapeze-like swings hanging from an A–frame structure mounted on a high platform. Riders launched themselves from these swings into the lake. The park saw its peak attendance between the early 1970s and the mid-1980s. After a downturn in popularity in the late 1980s, the park closed. Later development (1990–2004) Rock–A–Hoola Waterpark Byers sold the defunct park in August 1990 to Lake Dolores Group
