The maximum permitted length of an individual private dock on an artificial lake or river is the lesser of 50 feet from the water's edge or one-fourth of the width of the waterway measured from the water's edge at normal water levels. If the water level declines after installation, additional segments may be installed during the season as needed to maintain 80 feet of dock in 3 feet of water, up to a maximum length of 300 feet from the water's edge. These lengths shall be measured from the water's edge when the dock is installed. 16.7(1) A Class 3 private dock permit shall require docks or hoists to be in compliance with requirements in 16.3(461A,462A), except as provided in 16.9(461A,462A) and 16.10(461A,462A).ġ6.7(2) An individual private dock on a natural lake may be permitted by a Class 3 permit to extend 100 feet from the water's edge or far enough so that the outer 80 feet of the dock is in 3 feet of water when the dock is installed.
