Cedar Channel Control Dam is located on the English River system at the east end of Lake St. Joseph and was constructed in the 1930s. The dams were built to raise the water level of Lake St. Joseph as part of the Rat Rapids development. There are three dams, the concrete North Channel Dam with eight log sluices, the concrete South Channel Dam with four log sluices, and the earth Block Dam.
