Welcome

Protecting the Great Lakes and their rich maritime history through research, education and resource protection. The sanctuary works to ensure that future generations can enjoy these underwater treasures.

Boundary Expansion

NOAA has announced it will prepare an Environmental Impact Statement (EIS) to consider expansion of the sanctuary's current boundaries. Expansion would protect important national treasures through the sanctuary's research and monitoring, education, and resource protection programs, while allowing recreational use of the resources.
