The department has management control over the lakes and ponds which it owns or leases. It may establish the terms and conditions under which the public may use the lakes and ponds for fishing, boating, picnicking, and other related activities. Before taking effect, the conditions and terms must be approved by the board and a majority of the county legislative delegation of the county where the lake or pond is located and published in a newspaper of general circulation in the county.
Any person violating the terms and conditions of this section is guilty of a misdemeanor and, upon conviction, must be fined not more than two hundred dollars or imprisoned for not more than thirty days.
