Mallows Bay-Potomac River National Marine Sanctuary
Check out the newest National Marine Sanctuary
NOAA, the state of Maryland, and Charles County today announced the designation of a new national marine sanctuary to protect the remains of more than 100 abandoned steamships and vessels built as part of America’s engagement in World War I. Mallows Bay-Potomac River National Marine Sanctuary, about 40 miles south of Washington, D.C., is the first national marine sanctuary designated since 2000.
The state of Maryland nominated the area for sanctuary designation in 2014 to protect and conserve the shipwrecks and cultural heritage resources, as well as to foster education and research partnerships, and to increase opportunities for public access, tourism and economic development. The nomination enjoyed broad community support as well as strong support from the Maryland congressional delegation.
Mallows Bay is most renowned for its “Ghost Fleet,” the partially submerged remains of more than 100 wooden steamships that were built in response to threats from World War I-era German U-boats that were sinking ships in the Atlantic. Although the ships never saw action during the war, their construction at more than 40 shipyards in 17 states reflected the massive national wartime effort that drove the expansion and economic development of communities and related maritime service industries. The fleet was brought to the Potomac River to be salvaged for scrap metal by a company in Alexandria, Virginia, not far from the sanctuary site.
NOAA, the state of Maryland, and Charles County will manage the national marine sanctuary jointly. The sanctuary designation will take effect following 45 days of Congressional session after publication of this action in the Federal Register.
