Inspection of dams; orders. 31.19(1g)(a)
“High hazard dam" means a large dam the failure of which would probably cause loss of human life.
“Low hazard dam" means a large dam the failure of which would probably not cause significant property damage or loss of human life.
“Significant hazard dam" means a large dam the failure of which would probably cause significant property damage but would probably not cause loss of human life.
Determination of dam size.
For the purposes of this section, a dam is considered to be a large dam if either of the following applies:
It has a structural height of 25 feet or more and impounds more than 15 acre-feet of water.
It has a structural height of more than 6 feet and impounds 50 acre-feet or more of water.
Inspection by the department.
At least once every 10 years the department shall conduct a detailed inspection of each high hazard dam and each significant hazard dam.
Owners of each high hazard dam, each significant hazard dam, and each low hazard dam shall engage a professional engineer registered under s. 443.04
to inspect the dam as specified in this paragraph.
An owner of a high hazard dam shall cause the dam to be inspected at least 4 times between each inspection conducted by the department under par. (a)
. An owner of a significant hazard dam shall cause the dam to be inspected at least 2 times between each inspection conducted by the department under par. (a)
. An owner of a low hazard dam shall cause the dam to be inspected at least once every 10 years.
The owner of a dam required to be inspected under this paragraph shall submit to the department, no later than 90 days after the date of the inspection, a report of the results of the inspection. The report shall include information on any deficiencies in the dam, recommendations for addressing those deficiencies, and recommendations on improving the safety and structural integrity of the dam.
The department shall classify each dam in this state as a high hazard, significant hazard, or low hazard dam for the purpose of this section.
Exemption for federally inspected dams.
Notwithstanding the inspection requirements under pars. (a)
, an inspection under par. (a)
is not required if the dam is inspected periodically by or under the supervision of a federal agency in a manner which is acceptable to the department and if the results of each inspection are made available to the department.
Inspection upon complaint.
If the department receives a complaint in writing from the mayor of a city, supervisor of a town or the president or trustee of a village which alleges that a dam maintained or operated in or across any navigable or nonnavigable waters or a reservoir is in an unsafe condition or if the department receives a complaint in writing from a person which alleges that the person's property or any property under the person's control is endangered by a dam or reservoir, the department shall investigate or cause an investigation to be made of the complaint.
The department may inspect or cause an inspection to be made of any dam or reservoir.
Order; reduction in water level.
If the department finds pursuant to an investigation that a dam or reservoir is not sufficiently strong or is unsafe and that the dam or reservoir is dangerous to life or property, it shall determine what alterations, additions or repairs are necessary and shall order the owner or person having control of the dam or reservoir to cause those alterations, additions or repairs to be made within a time specified in the order. If the department finds pursuant to an investigation that a dam or reservoir is not sufficiently strong or is unsafe and that the dam or reservoir is dangerous to life or property, it may cause to be drawn off, in whole or in part, the water in the reservoir or impounded by the dam if it determines that this action is necessary to prevent impending danger to persons or property.

Jurisdiction of department. 31.33(1)(1)
Dams heretofore or hereafter constructed; action for damages.
All mills and milldams lawfully erected or constructed, on streams not navigable at the time, under chapter 48, territorial laws of 1840, chapter 62, laws of 1857
, ch. 56
, R.S. 1858, ch. 146

, 1911 stats., ch. 146
, 1913 stats., or ch. 146
, 1915 stats., or any special, private or local act, or under any other act whatsoever, that are not now abandoned but are still in existence and use, and all dams heretofore or hereafter erected or constructed on streams not navigable in fact for any purpose, shall be subject to and regulated and controlled, so far as applicable, by ss. 31.02
, except that those sections do not prevent the owner of any land flooded or otherwise injured by any milldam from recovering by action at law, full compensation for all damages resulting to him or her in times past and that will result to him or her in the future in consequence of that flooding and injury but no damages suffered more than 3 years before the commencement of the action shall be recovered. The amount recovered constitutes a first lien upon the milldam and upon the mill, if any, and the lien may be enforced by execution sale of the property affected. In every such action the amount paid or secured to be paid under prior laws as damages shall be considered and proper allowance made therefor. The authority granted under this subsection to bring the action does not preclude the owner from proceeding under ch. 32
. The owner may not exercise his or her option to bring the action after condemnation proceedings have been commenced against his or her property under ch. 32
A license is granted to each owner of any such milldam now in existence and use, and to each owner of any such milldam hereafter constructed, to maintain and use the same to operate mills or machinery, or for any other lawful private or public purpose, but subject, however, to the supervision of the department acting under ss. 31.02
. The right created by the license shall follow the title to the milldam and a conveyance of the latter shall transfer the right to the grantee.
Whenever ss. 31.02
are applied to mills or milldams specified in sub. (1)
every reference in any of them to a “permit" or to a “grantee" of a permit shall be regarded as referring respectively to a license granted by this section and to the owner of such a mill or milldam.
The height to which water may be raised by any such milldam and the length or period of time for which it may be kept up each year, may be restricted and regulated by the orders of the department.
Violation of orders, penalties.
Every person, firm or corporation violating any of the orders respecting any such mill or milldam made by the department shall forfeit for each such violation a sum not exceeding $500 which may be recovered by civil action as provided by ch. 778
