What does “when out of water” mean in ANS regulations?

Legally, the acts of pulling plugs, draining, and removing vegetation must occur right on the boat ramp itself or in the immediate parking lot area. Fish cleaning stations located immediately adjacent to parking lots are also acceptable IF not signed as prohibited (some nonpaved areas do not allow draining to prevent excessive mud creation). Please be considerate to other boaters and traffic by using parking lot areas to perform these actions at high-traffic locations.
