The Grand Traverse Bay Underwater Preserve is an all volunteer non-profit 501 (c)3 which maintains an underwater preserve in Grand Traverse Bay. The purpose of the preserve is to promote underwater recreation and Maritime Heritage & Tourism in the Great Lakes.

  The Michigan Underwater Preserve system was created in 1980 through legislation supported and largely drafted by Michigan sport divers. Since then, divers have ensured that their sport will remain a high-quality activity with stiff penalties for disturbing the shipwrecks and their artifacts. It is a felony to remove or disturb artifacts in the Great Lakes. Those caught removing portholes, anchors, anchor chain, deadeyes, blocks, or other “souvenirs” will have their boat, car, and equipment confiscated immediately and will face up to two years imprisonment and stiff fines. Divers who have information about the theft of artifacts can report violations to the Michigan Department of Natural Resources by calling (800) 292-7800.

To sustain an Underwater Preserve by enhancing education, research and preservation of our Great Lakes and maritime heritage, and by the promotion of tourism and public recreation.
