  (a) "Vessel" means every description of craft or other contrivance used, or capable of being used, as a means of transportation in or on water.
  (b) "Navigable waters" means all public waters of the state in any river, stream, lake, reservoir, or other body of water, including all salt water bays, inlets, and estuaries within the jurisdiction of the state.

No person shall place, deposit, or dump any human excreta in or upon the navigable waters of this state, that are within any marina, yacht harbor, fresh water lake, or fresh water impoundment, from any vessel tied to any dock, slip, or wharf that has toilet facilities available for the use of persons on the vessel.

Any violation of this article is a misdemeanor.
