The “Grave Pool” is the local nickname that was attributed to Action Park’s wave pool. It was one of the first of its kind, and because state regulations defined it as a pool, the only thing Action Park was required to do was keep the water clean and have lifeguards on duty. There was always a minimum of 12 guards, and sometimes, there were as many as 20. On a busy weekend, the guards would make as many as 30 saves in the pool, as opposed to the average one or two per season that a guard anywhere else can expect to make.
