30.07(2)(a)(a) No person may place or operate a vehicle, seaplane, watercraft, or other object of any kind in a navigable water if it has any aquatic plants or aquatic animals attached to the exterior of the vehicle, seaplane, watercraft, or other object. This paragraph does not require a person to remove aquatic plants or aquatic animals from a vehicle, seaplane, watercraft, or other object during the period of time when the vehicle, seaplane, watercraft, or other object is being operated in the same navigable body of water in which the aquatic plants or aquatic animals became attached. 30.07(2)(b)(b) No person may take off with a seaplane, or transport or operate a vehicle, watercraft, or other object of any kind on a highway with aquatic plants or aquatic animals attached to the exterior of the seaplane, vehicle, watercraft, or other object. 30.07(3)(3) A law enforcement officer who has reason to believe that a person is in violation of sub. (2) may order the person to do any of the following: 30.07(3)(a)(a) Remove aquatic plants or aquatic animals from a vehicle, seaplane, watercraft, or other object of any kind before placing it in a navigable water. 30.07(3)(b)(b) Remove aquatic plants or aquatic animals from a seaplane before taking off with the seaplane. 30.07(3)(c)(c) Remove from, or not place in, a navigable water, a vehicle, seaplane, watercraft, or other object of any kind. 30.07(3)(d)(d) Not take off with a seaplane, or transport or operate a vehicle, watercraft, or other object of any kind on a highway. 30.07(4)(4) Subsection (2) does not prohibit a person from doing any of the following: 30.07(4)(am)(am) Transporting or operating commercial aquatic plant harvesting equipment that has aquatic plants or animals attached to the exterior of the equipment if the equipment is owned or operated by a local governmental unit, if the equipment is being transported or operated for the purpose of cleaning the equipment to remove aquatic plants or animals, and if the person transports the equipment to, or operates the equipment at, a suitable location away from any body of water. 30.07(4)(b)(b) Transporting or operating a vehicle, seaplane, watercraft, or other object of any kind with duckweed that is incidentally attached to the exterior of the vehicle, seaplane, watercraft, or other object. 30.07(5)(a)(a) The department shall prepare a notice that contains a summary of the provisions under this section and shall make copies of the notice available to owners required to post the notice under par. (b). 30.07(5)(b)(b) Each owner of a public boat access site shall post and maintain the notice described in par. (a). 30.07(6)(6) No person may refuse to obey the order of a law enforcement officer who is acting under sub. (3). 30.07 HistoryHistory: 2009 a. 55 ss. 9, 13, 14; 2011 a. 265. 30.1030.10 Declarations of navigability. 30.10(1)(1) Lakes. All lakes wholly or partly within this state which are navigable in fact are declared to be navigable and public waters, and all persons have the same rights therein and thereto as they have in and to any other navigable or public waters. 30.10(2)(a)(a) Subject to par. (b) and except as provided under sub. (4) (c) and (d), all streams, sloughs, bayous, and marsh outlets, which are navigable in fact for any purpose whatsoever, are declared navigable to the extent that no dam, bridge, or other obstruction shall be made in or over the same without the permission of the state. 30.10(2)(b)(b) If the department makes a determination that a stream or portion of a stream is not navigable and a dam is constructed on the stream that modifies the flow of the stream or portion of the stream as compared to the natural flow of the stream or portion of the stream prior to its construction, and if an artificial impoundment created by the dam is or has been subject to a federal fish and wildlife service Partners for Fish and Wildlife Habitat Development Agreement or, as determined by the department, a similar publicly administered environmental restoration project, then the department may not change its determination of non-navigability with respect to the stream or portion of the stream unless all of the following conditions are met: 30.10(2)(b)1.1. All structures that affect the flow of the stream or portion of the stream are removed. 30.10(2)(b)2.2. All changes to the stream or land adjacent to the stream that could affect the flow of the stream or portion of the stream are substantially returned to their natural state. 30.10(2)(b)3.3. A department evaluation of the navigability of the stream or portion of the stream conducted after the conditions in subds. 1. and 2. are met indicates that the department’s determination of non-navigability should be changed. 30.10(3)(3) Enlargements or improvements in navigable waters. All inner harbors, turning basins, waterways, slips and canals created by any municipality to be used by the public for purposes of navigation, and all outer harbors connecting interior navigation with lake navigation, are declared navigable waters and are subject to the same control and regulation that navigable streams are subjected to as regards improvement, use and bridging. 30.10(4)(a)(a) This section does not impair the powers granted by law to municipalities to construct highway bridges, arches, or culverts over streams. 30.10(4)(b)(b) The boundaries of lands adjoining waters and the rights of the state and of individuals with respect to all such lands and waters shall be determined in conformity to the common law so far as applicable, but in the case of a lake or stream erroneously meandered in the original U.S. government survey, the owner of title to lands adjoining the meandered lake or stream, as shown on such original survey, is conclusively presumed to own to the actual shorelines unless it is first established in a suit in equity, brought by the U.S. government for that purpose, that the government was in fact defrauded by such survey. If the proper claims of adjacent owners of riparian lots of lands between meander and actual shorelines conflict, each shall have his or her proportion of such shorelands. 30.10(4)(c)(c) Notwithstanding any other provision of law, farm drainage ditches are not navigable within the meaning of this section unless it is shown that the ditches were navigable streams before ditching. For purposes of this paragraph, “farm drainage ditch” means any artificial channel which drains water from lands which are used for agricultural purposes. 30.10(4)(d)(d) A drainage district drain located in the Duck Creek Drainage District and operated by the board for that district is not navigable unless it is shown, by means of a U.S. geological survey map or other similarly reliable scientific evidence, that the drain was a navigable stream before it became a drainage district drain. 30.10 Cross-referenceCross-reference: See also chs. NR 300 and 320, Wis. adm. code. 30.10 AnnotationWhen there are 2 owners of land adjacent to a disputed parcel erroneously meandered under sub. (4), the judge is to divide the parcel proportionately on an equitable, but not necessarily equal, basis. Kind v. Vilas County, 56 Wis. 2d 269, 201 N.W.2d 881 (1972). 30.10 AnnotationThe department of natural resources properly considered the existence of beaver dams and ponds and the periods of high water caused by spring runoffs in determining the navigability of a creek. The dams and ponds were normal and natural to the stream, and the periods of high water were of a regularly recurring, annual nature. DeGayner & Co. v. Department of Natural Resources, 70 Wis. 2d 936, 236 N.W.2d 217 (1975). 30.10 AnnotationAn owner of land on a meandered lake takes only to the actual shoreline. An owner does not have a “proper claim” to an isolated parcel separated from the remainder of the lot by the lake, making sub. (4) (b) inapplicable as parcels separated by a lake are not “adjacent.” State Commissioners of Board of Public Lands v. Thiel, 82 Wis. 2d 276, 262 N.W.2d 522 (1978). 30.10 AnnotationA department of natural resources declaration of navigability subjecting private property to sub. (1) was a taking. Zinn v. State, 112 Wis. 2d 417, 334 N.W.2d 67 (1983). 30.10 AnnotationThe department of natural resources has the authority, as well as the obligation, to determine whether the waters of the state are navigable in fact and subject to regulation under ch. 30, another agency’s prior ancillary finding to the contrary notwithstanding. Turkow v. Department of Natural Resources, 216 Wis. 2d 273, 576 N.W.2d 288 (Ct. App. 1998), 97-1149. 30.10 AnnotationThis chapter applies to navigable ditches that were originally navigable streams. If a navigable ditch was originally nonnavigable or had no previous stream history, the department of natural resources’ jurisdiction depends upon the facts of the situation. 63 Atty. Gen. 493.

30.10230.102 Website information. 30.102(1)(1) Navigability determination and ordinary high-water mark identification. If the department makes a determination that a waterway is navigable or is not navigable or identifies the ordinary high-water mark of a navigable waterway, the department shall publish that information on the department’s Internet website. Any person may rely on the information posted under this section as being accurate. This section does not restrict the ability of a person to challenge the accuracy of the information posted under this section. 30.102(2)(2) Application status. To the greatest extent possible, the department shall publish on the department’s Internet website the current status of any application filed with the department for a permit, license, or other approval under this chapter. The information shall include notice of any hearing scheduled by the department with regard to the application. 30.102 HistoryHistory: 2011 a. 167; 2017 a. 365 s. 112. 30.10330.103 Identification of ordinary high-water mark by town sanitary district. A town sanitary district may identify the ordinary high-water mark of a lake that lies wholly within unincorporated territory and wholly within the town sanitary district. The department may not identify an ordinary high-water mark of a lake that is different than the ordinary high-water mark identified by a town sanitary district under this section. 30.103 HistoryHistory: 1997 a. 237. 30.10530.105 Determining footage of shoreline. In determining footage of shoreline for purposes of s. 30.50 (4q), 30.77 (3) (ac), (ae) and (am) and 60.782 (2), towns, villages, cities, public inland lake protection and rehabilitation districts and town sanitary districts shall measure by use of a map wheel on the U.S. geological survey 7 1/2 minute series map. 30.105 HistoryHistory: 1995 a. 152 s. 9; 1995 a. 349 s. 11. NAVIGABLE WATERS AND NAVIGATION IN GENERAL
30.1130.11 Establishment of bulkhead lines. 30.11(1)(1) Who may establish. Any municipality may, subject to the approval of the department, by ordinance establish a bulkhead line and from time to time reestablish the same along any section of the shore of any navigable waters within its boundaries. 30.11(2)(2) Standards for establishing. Bulkhead lines shall be established in the public interest and shall conform as nearly as practicable to the existing shores, except that in the case of leases under sub. (5) and s. 24.39 (4) bulkhead lines may be approved farther from the existing shoreline if they are consistent with and a part of any lease executed by the board of commissioners of public lands. 30.11(3)(3) How established. Whenever any municipality proposes to establish a bulkhead line or to reestablish an existing bulkhead line, the municipality shall indicate both the existing shore and the proposed bulkhead line upon a map and shall file with the department for its approval 6 copies of the map and 6 copies of the ordinance establishing the bulkhead line. The map shall use a scale of not less than 100 feet to an inch or any other scale required by the department. The map and a metes and bounds description of the bulkhead line shall be prepared by a professional land surveyor licensed under ch. 443. The department may require the installation of permanent reference markers to the bulkhead line. Upon approval by the department, the municipality shall deliver the map, description, and ordinance to the office of the register of deeds of the county in which the bulkhead line lies, to be recorded by the register of deeds. 30.11(4)(4) Riparian rights preserved. Establishment of a bulkhead line shall not abridge the riparian rights of riparian owners. Riparian owners may place solid structures or fill up to such line. 30.11(5)(a)(a) Prior to the execution of any lease by the board of commissioners of public lands concerning rights to submerged lands or rights to fill in submerged lands held in trust for the public under s. 24.39, the department shall determine whether the proposed physical changes in the area as a result of the execution of the lease are consistent with the public interest. Thirty days before making its determination, the department shall notify, in writing, the clerk of the county and clerk of the city, village, or town in which the changes are proposed and the U.S. army corps of engineers of the application for the lease. In making its finding the department shall give consideration to all reports submitted to it. The department shall not approve a lease applied for under s. 24.39 (4) (a) 2. if the department determines that the lease may threaten excessive destruction of wildlife habitat. 30.11(5)(b)(b) When considering leases to allow certain initial improvements such as, but not restricted to, filling on submerged lands to create sites for further facilities, the department may determine whether such initial improvements are consistent with the public interest in the navigable waters involved even though the exact final use to which these improvements will be put is not known. The department, at the time it finds that a proposed lease would be consistent with the public interest in the navigable waters involved, may include in its findings such limitations upon the use of improvements as it considers necessary to confine their use to functions primarily related to water transportation or otherwise of public benefit. The board of commissioners of public lands shall include in the lease such limitations on final use as is determined by the department. 30.11(5)(c)(c) Upon the complaint of any person to the department that current use made of rights leased under s. 24.39 (4) is inconsistent with both its original findings and the public interest, the department shall hold a public hearing thereon after the publication of a class 2 notice, under ch. 985. If the department finds that the present use conforms neither to its original finding nor to the present public interest, it shall submit its findings to the governor. The governor may cause the attorney general or the district attorney of the proper county to bring action in the name of the state in a court of competent jurisdiction to declare the lease terminated and to institute appropriate action for removal of structures or cessation of practices in violation of such lease. 30.11(6)(6) Shoreline not invalidated. A shoreline lawfully established before January 1, 1960, is a lawfully established bulkhead line. 30.11 AnnotationA bulkhead line is not merely the natural shoreline, but one legislatively established by a municipality. It may differ from the existing shoreline and is also distinguishable from the low- and high-water marks previously judicially defined. State v. McFarren, 62 Wis. 2d 492, 215 N.W.2d 459 (1974). 30.11 AnnotationThe private right to fill lakebeds granted under this section does not preempt the zoning power of a county over shorelands under s. 59.971 [now s. 59.692]. State v. Land Concepts, Ltd. 177 Wis. 2d 24, 501 N.W.2d 817 (Ct. App. 1993). 30.11 AnnotationWhen a bulkhead line has been established, a riparian owner must nonetheless obtain a permit or contract pursuant to s. 30.20 prior to removing material from the bed of a navigable water landward of the bulkhead line, but within the original ordinary high water mark. 63 Atty. Gen. 445.
30.11 AnnotationA bulkhead line is not legally established until the filing requirements of sub. (3) are met. A bulkhead line established by a town on lands subsequently annexed to a municipality that has not established such line, remains in effect. 64 Atty. Gen. 112.
30.1230.12 Structures and deposits in navigable waters. 30.12(1)(1) Permits required. Unless an individual or a general permit has been issued under this section or authorization has been granted by the legislature, no person may do any of the following: 30.12(1)(a)(a) Deposit any material or place any structure upon the bed of any navigable water where no bulkhead line has been established. 30.12(1)(b)(b) Deposit any material or place any structure upon the bed of any navigable water beyond a lawfully established bulkhead line. 30.12(1g)(1g) Exemptions. A riparian owner is exempt from the permit requirements under this section for the placement of a structure or the deposit of material if the structure or material is located in an area other than an area of special natural resource interest, does not interfere with the riparian rights of other riparian owners, and is any of the following: 30.12(1g)(a)(a) A deposit of sand, gravel, or stone that totals less than 2 cubic yards and that is associated with any activity or project that is exempt from an individual permit or a general permit under this subchapter. 30.12(1g)(b)(b) A structure, other than a pier or a wharf, that is placed on a seasonal basis in accordance with rules promulgated by the department. 30.12(1g)(c)(c) A fish crib, spawning reef, wing deflector, or similar device that is placed on the bed of navigable waters for the purpose of improving fish habitat. 30.12(1g)(d)(d) A bird nesting platform, wood duck house, or similar structure that is placed on the bed of a navigable water for the purpose of improving wildlife habitat. 30.12(1g)(e)(e) A boat shelter, boat hoist, or boat lift that is placed on a seasonal basis adjacent to the riparian owner’s pier or wharf or to the shoreline on the riparian owner’s property, in accordance with rules promulgated by the department. 30.12(1g)(f)1.b.b. It extends no further than to a point where the water is 3 feet at its maximum depth as measured at summer low levels, or to the point where there is adequate depth for mooring a boat or using a boat hoist or boat lift, whichever is farther from the shoreline. 30.12(1g)(f)1.c.c. It has no more than 2 boat slips for the first 50 feet of the riparian owner’s shoreline footage and no more than one additional boat slip for each additional 50 feet of the riparian owner’s shoreline footage. 30.12(1g)(f)2.2. Notwithstanding the width limitation in subd. 1., a pier may have an area as a loading platform that is more than 6 feet wide if the surface area of the platform does not exceed 200 square feet. 30.12(1g)(g)(g) An intake structure and pipe that is placed on the bed of a navigable water for the purpose of constructing a dry fire hydrant to supply water for fire protection. 30.12(1g)(h)(h) A piling that is driven into the bed of a navigable water adjacent to the owner’s property for the purpose of deflecting ice, protecting an existing or proposed structure, or providing a pivot point for turning watercraft. 30.12(1g)(i)(i) Riprap in an amount not to exceed 100 linear feet that is placed to replace existing riprap located in an inland lake or Great Lakes water body and that includes the replacement of filter fabric or base substrate. 30.12(1g)(j)(j) Riprap in an amount not to exceed 300 linear feet that is placed to repair existing riprap located in an inland lake or Great Lakes water body, and that consists only of the placement of additional rock or the redistribution of existing rock within the footprint of the existing riprap. 30.12(1g)(jm)(jm) Riprap in an amount not to exceed 200 linear feet that is placed in a river or inland lake, or in an amount not to exceed 300 linear feet that is placed in a Great Lakes water body, and to which all of the following apply:
