Designation and marking of fish sanctuaries in rivers and streams

The department may select any place upon any river or stream within this State as a fish sanctuary. Upon making this selection, the board, upon approval in writing of a majority of the members of the county legislative delegation from the county in which this proposed fish sanctuary is to be located, may designate and set apart the place as a fish sanctuary. A sanctuary may not exceed two miles in length along any river or stream. When a sanctuary is so designated and set apart, the board shall have it adequately and conspicuously marked and shall designate the limits of it in all directions.
