Competed in 1991, this vertical slot ladder is located approximately 42 miles upriver of Lake Michigan. This is the last ladder in Michigan before fish enter Indiana. This ladder is very deep and fish pass through the ladder and exit directly into the river channel just above the Niles Dam. French Paper Company produces electricity at this dam. A viewing window is used to count all fish prior to passing into Indiana. The Niles fish ladder cost $2.5 million dollars to construct.
