Aids to Navigation

Individuals and nonprofit organizations may identify hazards on state waterways by placing a sign or marker at the hazard. Only department approved signs, markers, or buoys may be used to mark a hazard. A white plastic milk jug attached by a cord to the hazard may also be used. The sign or marker must:

  • display the name and telephone number of the individual or nonprofit organization that placed it;
  • be maintained or removed by the individual or nonprofit organization when dictated by changing water conditions or seasonal changes;
  • be placed only to signal a hazard in the waterway; they may not be used to mark swim areas, safe channels, speed limits or water skiing cources;
  • be located on state waterways; they are not allowed on navigable waters with federal jurisdiction.
