Swim rafts and mooring buoys.
(1) Swim rafts or mooring buoys will not be authorized where such structures will interfere with heavily traveled routes for watercraft, commercial fishing areas or on designated public use - wilderness beaches.
(2) Swim rafts or mooring buoys may be authorized on aquatic lands shoreward of the -3 fathom contour or within 200 feet of extreme low water or line of navigability whichever is appropriate. The placement of rafts and buoys beyond the -3 fathom contour or 200 feet will be evaluated on a case by case basis.
(3) No more than one structure may be installed for each ownership beyond extreme low water or line of navigability. However, ownerships exceeding 200 feet as measured along the shoreline may be permitted more installations on a case by case basis.
(4) Swim rafts or buoys must float at least 12" above the water and be a light or bright color.
