Wis. Stat. § 31.12
in effect(1) The grantee of a permit under s. 31.06, to construct, maintain and operate a dam, before commencing any work of construction authorized by the permit, shall submit to the department a complete map and profile on the scale of not less than one inch per 1,000 feet showing the land that may be affected by the construction and maintenance of the dam, or by any flowage that may be caused thereby, and the outline of the flowage, and such other hydrographic and topographic data as the department may prescribe, and shall also file complete detailed plans and specifications for the proposed dam, including all booms, piers, or other protection works.
(2) The department shall examine the map, profile, plans and specifications; shall hear the grantee thereon and may reject the same or any part thereof, if unsatisfactory or incomplete, or may suggest and require modifications thereof. If the map, profile and plans and specifications are satisfactory and complete, or, if the same shall be modified as suggested and required, the department shall so find and approve the same, and thereupon the grantee may construct the proposed dam in accordance therewith, but the department may, at any time during the construction of any dam and in the interest of the public safety, or of any public rights in navigable waters, authorize, order or require such changes in the plans and specifications and the construction of the dam as shall be necessary.
(3) If the department, in the case of an application for a permit to construct a dam with a capacity of less than 250 hydraulic horsepower at ordinary stage of water, shall find that the information and data furnished in the original or amended application is sufficient, the applicant shall not be required to furnish the additional or more detailed information or data specified in subs. (1) and (2). The department may, however, at any time during the construction of any such dam authorize, order or require changes in the construction or the method or plan of construction thereof, as provided in sub. (2).
(4) Within 10 days after the completion of any dam the grantee shall file with the department a verified statement that the same was constructed in accordance with the plans and specifications approved by the department; or in case no plans and specifications were required to be filed, then that the dam was constructed in accordance with the description contained in the application.
(5) The department shall establish an expedited procedure for approval of plans for low hazard dams, as defined in s. 31.19 (1g) (b), under this section. The expedited procedure shall apply, in lieu of the procedure under this section, if the department determines that all of the following are satisfied:
(a) The plan design is of a common construction and size or is for a minor addition to an existing dam.
(b) The plan design is submitted by a registered professional engineer.
(c) The plan design is submitted by a person who has designed similar dams and none of those similar dams has caused adverse impacts to the environment.
(d) The plan design contains no unusual siting requirements or other unique design features.
(e) The plan design is for a dam that is located entirely on land that the permit grantee owns or that is located entirely on land for which the permit grantee has acquired an easement.
(f) The plan design is not likely to have an adverse impact on the environment.
