The Potomac River is a major river in the Mid-Atlantic region of the United States that flows from the Potomac Highlands in West Virginia to the Chesapeake Bay in Maryland. It is 405 miles (652 km) long, with a drainage area of 14,700 square miles (38,000 km2), and is the fourth-largest river along the East Coast of the United States and the 21st-largest in the United States. Over 5 million people live within its watershed.
The Chesapeake Bay is the largest estuary in the United States. The Bay is located in the Mid-Atlantic region and is primarily separated from the Atlantic Ocean by the Delmarva Peninsula, including parts of the Eastern Shore of Maryland, the Eastern Shore of Virginia, and the state of Delaware. The mouth of the Bay at its southern point is located between Cape Henry and Cape Charles. With its northern portion in Maryland and the southern part in Virginia, the Chesapeake Bay is a very important feature for the ecology and economy of those two states, as well as others surrounding within its watershed. More than 150 major rivers and streams flow into the Bay's 64,299-square-mile (166,534 km2) drainage basin, which covers parts of six states, New York, Pennsylvania, Delaware, Maryland, Virginia, and West Virginia, and all of Washington, D.C.

Thunder Bay National Marine Sanctuary and Underwater Preserve is a United States National Marine Sanctuary on Lake Huron's Thunder Bay, within the northeastern region of the U.S. state of Michigan. It protects an estimated 116 historically significant shipwrecks ranging from nineteenth-century wooden side-wheelers to twentieth-century steel-hulled steamers. There are a great many wrecks in the sanctuary, and their preservation and protection is a concern for national policymakers.

San Pedro Underwater Archaeological Preserve State Park is a Florida State Park located in 18 feet (5.5 m) of water, approximately 1.25 nautical miles (2.32 km) south of Indian Key. It became the second Florida Underwater Archaeological Preserve when it opened to the public in 1989. The heart of the park is the San Pedro, a submerged shipwreck from a 1733 Spanish flotilla, around which visitors can dive and snorkel. The San Pedro, a 287-ton Dutch-built vessel, and 21 other Spanish ships under the command of Rodrigo de Torres left Havana, Cuba, on Friday, July 13, 1733, bound for Spain. The San Pedro carried a cargo of 16,000 silver Mexican pesos and crates of Chinese porcelain. A hurricane struck the fleet, while entering the Straits of Florida, and sank or swamped most of the fleet. The wrecksite includes an "eighteenth century anchor, replica cannons, ballast stones encrusted with coral, a dedication plaque, and a mooring buoy system." The wreck was added to the U.S. National Register of Historic Places on May 31, 2001.
