Great Lakes Maritime Heritage Assessment Act of 2015

This bill requires the National Oceanic and Atmospheric Administration (NOAA) to assess and report on the cultural and historic resources in the waters of the Great Lakes. NOAA must make recommendations in the report on whether: (1) underwater geographic areas in the Great Lakes should be designated as national marine sanctuaries to protect resources of historical and archeological significance; and (2) the designation of a network of underwater Great Lakes areas that protect those resources could bring significant educational opportunities, economic development, jobs, and tourism to the Great Lakes region.
