Featured in this photo is a temporary cofferdam made of sheet piles. This dam is used to keep the water from the Rouge River, the water on the far side of the dam, from flowing into the canal on the near side. Although it is difficult to tell, the water levels are actually quite different on each side of the cofferdam. By holding back the water from the Rouge River, construction crews can perform work on the banks of the canal in a dry environment instead of working beneath the surface of the water.
