Section R. 299.6003 - Straits of Mackinac Great Lakes state bottomland preserve; establishment

Rule 3. The following described area is established as the Straits of Mackinac Great Lakes state bottomland preserve: That area of bottomlands of the Straits of Mackinac which connect Lake Michigan and Lake Huron, extending upward and including the surface of the water with a western boundary beginning at the longitude 84 degrees 56'22"W on the south shore, an official NOAA triangulation point located in Emmett county about 1/2 mile east of station point cabin on NOAA chart 14881, extending northward to St. Helena shoal buoy, 84 degrees 55'21"W, and then generally northeastward to the north shore at a point where the dividing line between sections 5 and 8, T40N, R4W, of Mackinac county intersects the ordinary high-water mark. The eastern boundary shall be a line running directly north and south at longitude 84 degrees 30'W between Bois Blanc Island and the southern peninsula (Cheboygan county). The northern boundary shall begin at the place where the western boundary strikes the northern peninsula and extend generally eastward along the ordinary high-water mark, to a point north of St. Ignace where the dividing line between sections 6 and 7, T40N, R4W, of Mackinac county intersects the ordinary high-water mark, approximately 45 degrees 52'54"N latitude, and then directly true eastward to Mackinac Island. The boundary then moves generally south and eastward along the ordinary high-water mark of the south side of Mackinac Island until it reaches the southern tip of the east breakwall extending outward from Mission point to Mackinac Island. The northern boundary then extends in a southwesterly direction from the tip of the breakwall to the abandoned lighthouse on the west end of Round Island and then along the ordinary high-water mark of the western shore of Round Island and then along the ordinary high-water mark of the southern shore of Round Island to the point of land at the southeastern tip of Round Island. The northern boundary extends from this point across to Lime Kiln Point on Bois Blanc Island and then along the ordinary high-water mark of the southern shore until it intersects the eastern boundary at 84 degrees 30'W longitude. The southern boundary shall start at the intersection of the western boundary with the southern peninsula, 84 degrees 56'22"W longitude, and extends generally eastward along the ordinary high-water mark to a point where the eastern boundary intersects the southern peninsula, 84 degrees 30'W longitude, Cheboygan, Emmet, and Mackinac counties, Michigan, which area contains 148 square miles, more or less.
