Wisconsin Statutes Public Lands, Waters and Natural Resources (Ch. 23 to 33) § 23.11. General powers

(1) In addition to the powers and duties heretofore conferred and imposed upon said department by this chapter it shall have and take the general care, protection and supervision of all state parks, of all state fish hatcheries and lands used therewith, of all state forests, and of all lands owned by the state or in which it has any interests, except lands the care and supervision of which are vested in some other officer, body or board; and said department is granted such further powers as may be necessary or convenient to enable it to exercise the functions and perform the duties required of it by this chapter and by other provisions of law. But it may not perform any act upon state lands held for sale that will diminish their salable value.

(2) Whenever any lands placed by law under the care and supervision of the department are inaccessible because surrounded by lands belonging to individuals or corporations, and whenever in the opinion of the department the usefulness or value of such lands, whether so surrounded or not, will be increased by access thereto over lands not belonging to the state, the department may acquire such lands as may be necessary to construct highways that will furnish the needed access.

(4) The department shall have police supervision over all state-owned lands and property under its supervision, management and control, and its duly appointed agents or representatives may arrest, with or without warrant, any person within such area, committing an offense against the laws of this state or in violation of any rule of the department in force in such area, and deliver such person to the proper court of the county wherein such offense has been committed and make and execute a complaint charging such person with the offense committed. The district attorney of the county wherein such offense has been committed shall appear and prosecute all actions arising under this subsection.

(5) The department may require an applicant for a permit or statutory approval which the department, by order, may grant, to submit an environmental impact report if the area affected exceeds 40 acres, the estimated cost of the project exceeds $25,000, or the applicant is requesting approval for a high capacity well described in s. 281.34(4)(a)1. to 3.
