Mallows Bay-Potomac River
Discover Mallows Bay
A special place on the John Smith Chesapeake Trail is steeped in history, wildlife and recreational opportunities. Approximately 30 miles south of Washington, D.C. on the Potomac River in Charles County, Maryland is Mallows Bay. This is a place where years ago, ships built by the Emergency Fleet Corporation between 1917 and 1919 under the auspices of the United States Shipping Board were sunk once they were no longer needed. While they may have once been nothing but a junkyard in the Bay, they are now ecological habitats that are teeming with wildlife. Chesapeake Conservancy is a lead partner in an effort to designate this special place as the next National Marine Sanctuary. Read on below to see how you can help in this community-led effort, and for an experience you won’t forget, plan a trip to paddle around and view the shipwrecks up close at low tide.
While nothing beats seeing the beauty of Mallows Bay – Potomac River in person, we’ve created a few ways that you can tour the Ghost Ships of Mallows Bay from your computer or mobile device. We offer two types of virtual tours. Riverview is a virtual tour created by Terrain360, similar to Google Street View, that takes you through the shipwrecks as if you are in a kayak paddling the bay.

Establishing a national treasure
Chesapeake Conservancy is a lead partner in an effort to designate this special place as the next National Marine Sanctuary, and the first ever in the Chesapeake. In addition to unique natural resources, Mallows Bay – Potomac River boasts rich American Indian and African American history. This section of the Potomac River is part of the traditional lands and cultural landscape of the Piscataway-Conoy nation, as well as the site of important archaeological findings. African Americans have been a part of the area’s history for centuries, as well, with history related to African slaves landing on Maryland’s shores, fighting in the Civil War, and building many of the wooden steamships that now rest in the shallow waters of Mallows Bay – Potomac River.
Mallows Bay – Potomac River’s “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.
