Zug Island is a heavily industrialized island in Detroit. It is located where the mouth of the River Rouge spills into the Detroit River. Zug Island is not a natural island in the river; it was formed when a shipping canal was dug along the southwestern side of the island, allowing ships to bypass several hundred yards of twisting waterway near the mouth of the natural course of the lowest portions of the River Rouge. There have been industrial operation on Zug Island for many years, dating back to the early 1900’s. The largest corporation that operates on Zug Island is U.S. Steel. You can sometimes see the shooting flames from the smokestacks on Zug Island from miles away.
