Ind. Code § 8-10-1-7.5

Sec. 7.5. The department of natural resources may establish and maintain, within all ports created under this chapter and in operation on July 1, 1975, areas for the use of the citizens of this state for public fishing from the shore. The ports of Indiana shall cooperate fully with the department of natural resources in the implementation of this section. However, if the site of any public fishing area established under this section is subsequently leased to others for agricultural, industrial, or commercial purposes, or if required to maintain port security, the ports of Indiana may limit or halt public fishing in that area.
