Mallows Bay - Potomac River is a NOAA National Marine Sanctuary. As a core partner in the nomination process, the Chesapeake Conservancy is thrilled that Mallows Bay is the first to become a National Marine Sanctuary (NMS) designated in more than 20 years and the first ever in the Chesapeake. We are pleased to bring you this virtual tour of Mallows Bay which boasts the largest collection of historic shipwrecks in the Western Hemisphere. Its "ghost fleet" includes over 100 wooden steamships built for the U.S. Emergency Fleet during World War I, an effort that propelled America to the forefront of shipbuilding, as well as many other wrecks from Revolutionary times through the 1900s. These wrecks support diverse ecosystems that are teeming with marine life, attracting recreational fishing and ecotourists to the area.
