Question

The site has the lighthouses grouped by body of water:
Lake Superior
St. Marys River
Lake Michigan
Lake Huron
Lake St. Clair
Detroit River
Lake Erie
Lake Ontario
St. Lawrence River

Clicking on a lighthouse link will tell you whether or not the lighthouse is active.

Example, the Grand Haven South Pier
and Pierhead Inner Light:
