(a) The department by order shall declare a body of public water to be a prohibited area if:
(1) the department finds, according to a sanitary, chemical, or bacteriological survey, that the area contains aquatic life that is unfit for human consumption; or
(2) aquatic life from a prohibited area may have been transferred to that body of public water.
(b) The department shall modify or revoke an order according to the results of a sanitary, chemical, or bacteriological survey conducted by the department. The department shall file the order in the department's office and shall furnish without charge a copy of the order describing prohibited areas on request.
(c) The department shall conspicuously outline prohibited areas on maps and shall furnish the maps without charge on request. The failure of a person to obtain that information does not relieve that person from liability under this chapter.
