There were two cliff dives, one was maybe 15 feet and the other was about 20 feet. The water below these attractions is cold and about 20-25 feet deep. Unlike most of the deep pools, the bottom was a lighter color so you could actually see the bottom. According to Tom Fergus’ write in to Weird NJ, this was in response to an incident when someone jumped off the Cliff Dive and could not swim. “After that, they painted the pool white so they could see bodies lying on the bottom.”
Action Park and its defenders often pointed out that it was one of the first water parks in the nation and thus pioneered ideas that were later widely copied. This meant that visitors were using rides that had not been tested through practical use for very long. Ride designers may have had insufficient training in physics or engineering. "They seemed to build rides," one attendee recalls, "not knowing how they would work, and [then let] people on them."[18]
