Waterfront property owners with larger piers must register their piers with the DNR by April 1, 2011 to ensure their piers will be "grandfathered" from new size limits adopted by the State of Wisconsin in 2004.

Generally, a pier will need to be registered if it (a) is wider than 6 ft, but less than 8 ft in width, (b) has a platform at the end of the pier that has a surface area of less than 300 ft (w/ a max. width of 10 feet) and/or (c) more than 2 boat slips for the first 50 feet of shoreline frontage and 1 boat slip for each additional 50 feet of shoreline frontage.

To register a pier, a waterfront property owner must complete and mail a registration form to the DNR. To obtain a copy of the registration form and to find out more information about which piers need to be registered, please visit the DNR's website at:
