Mich. Comp. Laws § 324.48301: Free passage of fish; rules; fish ladders.

Sec. 48301.

The department shall prescribe rules and regulations to provide for the free passage and uninterrupted passage of fish over or through dams now in existence or that are or may be erected over rivers, streams, or creeks. The department may abrogate the provisions of this part that require the erection of fish ladders if the department determines that the height of the dam or the condition of the river or stream makes the installation of the ladders impracticable or unnecessary.
