Lake Dolores Waterpark (which also operated under the names Lake Dolores, Rock–A–Hoola Waterpark, and Discovery Waterpark) is a defunct waterpark in Newberry Springs in the Mojave Desert of Southern California.
In 2003, Olympic Gold Medalist and former professional football player Ron Brown and the Pro Players Network, a group of former and current professional athletes, formulated a proposal to purchase the park and turn it into a camp for disadvantaged youths, but this effort failed.
In recent years the park's hardware has been sold piecemeal. The "Big Bopper" waterslide was dismantled and shipped to Canada. It is now "Colossal Canyon" at Cultus Lake Waterpark near Vancouver.
The water slides and attractions are now gone. Repeatedly vandalized, much of the park is now in ruins.
In January 2009 the park appeared in an episode of the reality show Rob & Big on MTV. Professional skateboarder Rob Dyrdek and friends used the waterpark and its slides to perform skateboard stunts for the show.
