The island is the home of a historic lighthouse

, which in its current form dates to 1857, and adjacent quarters for the lightkeeper. The island also contains the sites of quarters for lifesaving service personnel and private-sector fishermen.

Light station

Thunder Bay Island Light, located on Thunder Bay Island's southeast tip, is one of the oldest operating lighthouses in Michigan. The third operating U.S. lighthouse in Lake Huron was built here in 1831, but it disintegrated almost at once and was rebuilt in 1832 of local limestone. This 40' high (12m) 1830s light tower was raised 10 feet (3 m) to a height of 50 feet (15m) in 1857, and sheathed with brick. A Fourth Order Fresnel lens

 was installed. This 1857 light tower is the current Thunder Bay Island Light, although the tower has been further altered and is currently 63 feet high.

A fog bell was installed in 1858, and the lightkeeper's house was rebuilt in 1868. A steam-powered fog horn was added in 1871, and a fog signal building sheltering the fog signal apparatus was constructed in 1892.

The lighthouse was manned during the seasons of Great Lakes navigation from 1832 until automation in 1983, more than 150 years.

Lifesaving station

Thunder Bay Island was also the site of a station, opened in 1876, operated by the United States Life-Saving Service

. It operated under that name until 1939, when the Life-Saving Service was consolidated into the Coast Guard.

Fishing station

In addition to the lightkeepers and lifesaving servicemen, who were employees of the U.S. federal government, private-sector families lived on Thunder Bay Island in the 1800s. During the 1830s and 1840s, a commodity market in barrelled fish

 arose on Lake Huron. The fresh-caught fish was quickly brought to a fishing station after being caught, and salted for preservation. A fishing station sprouted on Thunder Bay Island during this period, and an 1846 gazetteer counted 160 settlers on the island and 31 fishing boats that called the island their home port. Most of these fishing boats were small Mackinaw boat
