Right off of the I-15 freeway between Los Angeles and Las Vegas is an abandoned water park. Originally Lake Dolores, renamed Rock-a-Hoola in the 1990’s; this is supposedly the first waterpark built in the United States. The water source for the park was man-made Lake Dolores; which was fed by underwater springs. It opened in 1962, and did well enough to stay open through the 70’s & 80’s. It was closed, and with new ownership was opened again as “Rock-a-Hoola” until in 2004 it was permanently shut down due to bankruptcy. All but a couple of the slides have been removed and given to parks elsewhere.
