68 DETROIT RIVER. can be passed close-to, then starboard so as to bring the light over the stern, or nearly so; steer for Windmill Point light; the course will lead fair between the shoals extending from the head of Belle Isle and the foot of Isle aux Péches, the ends of which are marked by spar buoys. At the present time range lights are maintained by individual enterprise. They are on the north side of the river, a little below Windmill Point light.
