Formed in 1990, the Michigan-based Saginaw River Marine Historical Society (SRMHS) is a 501(c)(3) nonprofit organization and has members from Bay City, Saginaw, Midland and beyond! The SRMHS is an all volunteer organization interested in the maritime history of the Saginaw River (and its connecting waters), including the more than 650 commercial vessels that were built on the Saginaw River and around Saginaw Bay (of Lake Huron). At one time there were a half-dozen larger (and many more smaller ones) shipyards turning out schooners, freighters and passenger ships.​​
