White's Ford

The Dickerson Whitewater Course, on the Potomac River near Dickerson, Maryland, was built for use by canoe and kayak paddlers training for the 1992 Olympic Games in Spain. It was the first pump-powered artificial whitewater course built in North America, and is still the only one anywhere with heated water. It remains an active training center for whitewater slalom racing, swiftwater rescue training, and other whitewater activities. The facility is owned by the NRG Energy company. Except during special events, access requires membership in the Potomac Whitewater Racing Center, a USA Canoe/Kayak National Training Center.The course was constructed in 1991, inside a pre-existing straight, 900-foot (270 m)-long concrete channel, 40 feet (12 m) wide. Since 1959, the channel has returned cooling water from the Dickerson Generating Station to the Potomac River, 41 miles (66 km) upstream from Washington, D.C. Water is pumped from the river, warmed as much as 35 °F (20 °C) as it cools the power plant's three coal-fired generators, and then emptied into the channel for gravity flow back to the river. (The plant has three other generators which use a different cooling system.) Streamflow through the course is 200 cu ft/s (5.7 m3/s) to 600 cu ft/s (17 m3/s), depending on the operation of the plant's three coal-fired generators and their six cooling water pumps. In the summer months, when water temperature in the channel exceeds 100 °F (38 °C), the course is closed for health reasons. It is also closed when the Potomac River rises above 5 feet (1.5 m) on the Little Falls gauge 20,000 cu ft/s (570 m3/s), flooding the lower section of the course.

The Dickerson Generating Station is an 853 MW electric generating plant owned by NRG Energy, located approximately two miles west of Dickerson, Maryland, on the eastern banks of the Potomac River.

Clapham's Ferry, also known as Spinks Ferry, Lost Corner Farm, and Riverside, is a historic home located near Leesburg, Loudoun County, Virginia. It consists of a 2+1⁄2-story, three bay, Federal style main block of red sandstone, with a two-story sandstone kitchen addition built about 1849. It has a standing seam metal gable roof. Also on the property are the contributing log kitchen building, meat house, bank barn, corn crib, and tenant house.

The Little Monocacy River is a 10.1-mile-long (16.3 km) tributary stream of the Potomac River. Despite its name, the stream does not feed into the Monocacy River. The Little Monocacy is located almost entirely in Montgomery County, Maryland, and enters the Potomac just downstream from where the Monocacy enters the Potomac. Its headwaters rise southwest of Comus, and most of its approximately 17-square-mile (44 km2) watershed is farmland and pasture (60.56%) or forested land (36.03%).

Annington is a historic home located at Poolesville, Montgomery County, Maryland, United States. The house is constructed of brick, Flemish bond, consisting of three two-story sections: a main block three bays wide, a wing to the west two bays wide, and a wing to the east three bays wide. The house was built during the wheat boom of the early 1810s that the western counties of Maryland and nearby Virginia experienced with the opening of the Chesapeake and Ohio Canal. The Georgian house was built in about 1813, for Daniel Trundle, a planter, and member of the Maryland State Legislature for ten years. The site is a commanding one, overlooking the Potomac River, and during the American Civil War was a strategic lookout point and occupied by Union officers.Annington was listed on the National Register of Historic Places in 1978.

The Monocacy River () is a free-flowing left tributary to the Potomac River, which empties into the Atlantic Ocean via the Chesapeake Bay. The river is 58.5 miles (94.1 km) long, with a drainage area of about 970 square miles (2,500 km2). It is the largest Maryland tributary to the Potomac. The name "Monocacy" comes from the Shawnee name for the river Monnockkesey, which translates to "river with many bends." (However, another local tradition asserts that "Monocacy" means "well-fenced garden" in an Indian language.) The Monocacy National Battlefield lies alongside part of the river, marking an 1864 engagement during the American Civil War, the Battle of Monocacy Junction. The Chesapeake and Ohio Canal crosses over the river at the Monocacy Aqueduct, the largest of the 11 aqueducts on the canal.

The Monocacy Aqueduct — or C&O Canal Aqueduct No. 2 — is the largest aqueduct on the Chesapeake and Ohio Canal, crossing the Monocacy River just before it empties into the Potomac River in Frederick County, Maryland, USA. The 438 foot (133.5 m) aqueduct was built by three separate contractors between 1829 and 1833 at a cost of US$127,900.

East Oaks is a historic home and farm complex and national historic district located at Poolesville, Montgomery County, Maryland. It is a 156-acre (0.63 km2) farm complex consisting of a 2+1⁄2-story, c. 1829 Federal-period brick residence situated on a knoll surrounded by agricultural buildings and dependencies whose construction dates span more than a century. The complex of domestic and agricultural outbuildings includes a brick smokehouse, sandstone slave quarter, stone bank barn, stone dairy, and log and frame tenant house which are contemporaneous with the construction of the main dwelling. Other agricultural buildings include a small frame barn and machinery shed/corn crib from the end of the 19th century, and a block dairy barn from the mid 20th century.It was listed on the National Register of Historic Places in 1996.

Tuscarora Creek is a 12.8-mile-long (20.6 km) tributary of the Potomac River in Frederick County, Maryland, in the United States. The creek rises east of the community of Jefferson, about 6.4 miles (10.3 km) southwest of the city of Frederick, and flows south to its mouth at the Potomac.

Temple Hall is an early 19th-century Federal-style mansion and working farm near the Potomac River north of Leesburg in Loudoun County, Virginia.

White's Ferry, originally Conrad's Ferry, is an inactive cable ferry service that carried cars, bicycles, and pedestrians across the Potomac River between Loudoun County, Virginia and Montgomery County, Maryland, and is the last one of its kind to cross the Potomac. The location offered fishing services and water recreation including canoeing. It transported between 600 and 800 customers daily until its operations were suspended indefinitely in 2020 due to a legal dispute over the land surrounding it.
