Mallows Bay Park

Mallows Bay is situated south of Washington, D.C., along the tidal Lower Potomac River off the Nanjemoy Peninsula of Charles County, Maryland. This shallow embayment, and the waters immediately adjacent, boasts one of the largest assemblages of shipwrecks in the Western Hemisphere, known as the “Ghost Fleet” of Mallows Bay. This diverse collection of historic shipwrecks totals nearly 200 known vessels dating back to the Revolutionary War and World War I. In addition to the “Ghost Fleet,” archaeological artifacts discovered around Mallows Bay date back 12,000 years, indicating the presence of some of the region’s earliest American Indian cultures. 

Thriving populations of bald eagles, heron, beaver, river otter, deer, turtles and numerous aquatic species call this area home. Striped bass, white perch, channel catfish, blue crab, and others make this area particularly popular for recreational fishing. In fact, Mallows Bay is widely regarded as one of the best bass fishing areas in the country.

This ship graveyard in the Potomac is no accident. Most of the bay’s 200+ derelict vessels constitute the skeletal remains of an emergency fleet ordered by President Woodrow Wilson in 1917 as the U.S. entered World War I.

To shore up a merchant marine devastated by German U-boats, shipwrights on both coasts raced to meet the president’s goal of 1,000 new wooden steamships. Shipbuilding continued even after Germany’s surrender in November, 1918, but only a few hundred vessels were ever delivered to the government. All proved obsolete practically before ever setting sail.

Mallows Bay was pegged as a burial ground. Ships were burned there in a basin engineered for that purpose, then lined up in the bay and abandoned. Makeshift settlements later arose, inhabited by scrap-iron salvage operations ranging from Bethlehem Steel to desperate Depression-era wildcatters
