|Gravelly Shoal, MI|
Description: A lighthouse was established on the northwest tip of Charity Island in 1857 to help mariners sailing in Saginaw Bay. The main shipping channel into the bay lies west of Charity Island, which is ringed to a distance of a nearly two miles by shoals. Jutting out a mile and a half into Saginaw Bay from the mainland west of Charity Island is Point Lookout. While the point itself isn’t a navigational hazard itself, a gravelly shoal extends another two-and-a-half miles into the bay, and this unseen danger was certainly a menace to sailors.
During the 1920s, Gravelly Point Shoal Gas and Bell Buoy was anchored in twenty-four feet of water near the end of the shoal and displayed an occulting red light to warn ships of the hidden threat. In 1928, the effectiveness of the buoy was improved by changing its illuminant to acetylene and by moving it to the extreme edge of the shoal. Still, this aid was considered insufficient when there was a revival of shipping in Saginaw Bay in 1930. During the 1929 season the net tonnage handled by vessels entering the Saginaw River was 16,714, but by the following year the tonnage had increased more than six fold to 1,110,471. The channels in the Saginaw River had been improved so that deep-draft vessels of full lake size were now able to navigate the river as far as the outskirts of Saginaw City.
Many requests have been received from shipping interests for the establishment of a lightship or a light station at the entrance to Saginaw Bay. In entering this bay from Lake Huron it is necessary to clear the shoals off Charity Island on the north, Charity Island west shoal to the eastward of the entering vessel, and Gravelly Point Shoal to the westward. The latter shoal projects well out off Lookout Point and is particularly a menace to vessels. The weather conditions in the locality are inclined to be hazy, and there are few distinguishing marks along the shore.While the requests had been received for many years, the recent increase in marine traffic led Putnam to decide that immediate action was imperative. Putnam proposed that a first-class modern light and fog-signal station with radiobeacon be established to mark the entrance to the bay at a projected cost of $188,000.
In 1938, it was announced that the new permanent light structure would be built on Gravelly Shoal and that it would be funded by the Public Works Administration (PWA), an agency set up to the help the country’s economy recover following the Great Depression. The Lighthouse Service received $2,098,750 from the PWA for projects in twenty-eight states. Work on Gravelly Shoal Lighthouse began in 1938, and it was completed during the fall of 1941 at a cost of roughly $175,000. The modern navigational aid was placed in commission at the opening of navigation in 1942 and was controlled remotely from Tawas Lighthous.
The following description of the lighthouse was including in the 1941 Annual Report of the Lake Carriers’ Association:
The Gravelly Shoal Light Station, at the entrance to Saginaw Bay, was built in 24 feet of water, and in its remote control equipment bears considerable resemblance to Lake St. Clair station. Its control point is at Tawas City, approximately 18 miles away. This structure is built on the end of Gravelly Shoal. The foundation is a rock-filled cylindrical caisson constructed of interlocking steel sheet piling. This caisson is capped with a concrete deck, above which rises a 50 foot light tower.
The Art Deco tower design used at Gravelly Shoal had been employed earlier at Conneaut and Huron Harbor, Ohio, Indiana Harbor, Indiana, and Port Washington, Wisconsin. The steel tower was fabricated byWickes Boiler Company of Saginaw for $24,000, while John C. Meager of Bay City was awarded the contract for constructing the foundation and installing the tower.
Located in Saginaw Bay seven miles east and a little south of Au Gres. The lighthouse is owned by the Coast Guard. Tower closed.
