This image of Homer Dam seems deceptively modern, but the presence of the horse-drawn buggy indicates that it predates the wide use of automobiles in the area of Homer, Michigan.

The dam has long since ceased to be used as such, and the Kalamazoo River flows unimpeded beneath the roadway over the old dam gates.
