Studies have determined that the erosion problem along a well-defined zone in the vicinity of Hammond Bay Harbor, Presque Isle County, Michigan is attributed to the federal navigation structures. The Corps proposes to mitigate the shore erosion damage by a structural approach through construction of an artificially-filled groin at the site of severe harbor-induced damage. Several alternatives to the proposed action were considered. These studies involved the public at Hammond Bay, the local, state, and federal agencies in the consideration of the project. (Author).
