Tuscarora Creek (Potomac River tributary)

Nolands Ferry I Archeological Site is an archaeological site near the historic Noland's Ferry boat landing at mile 44.58 on the C&O Canal and Tuscarora. The Archeological Site is a prehistoric occupation site located in the Monocacy region of southern Frederick County, Maryland. Diagnostic artifacts at the site indicate that the site was almost continuously inhabited from the Paleo-Indian period to the early 19th century, with the most substantial inhabitation occurring during the Late Woodland period.The site was listed on the National Register of Historic Places in 1985. Noland's Ferry, for which the site is named, has a broad history from the mid-1700s, with some of America's founding leaders among its customers.

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.

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%).

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.

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.

White's Ford was an important ford over the Potomac River during the American Civil War. It was used in many major actions, including the crossing into Maryland of the Confederate army prior to the Maryland Campaign and Confederate Major General J.E.B. Stuart's ride around Union Major General George B. McClellan on October 10, 1862, when he used the ford to cross into Loudoun County, Virginia. It is located a few miles above present-day White's Ferry. The ford was named after Captain Elijah V. White, a Confederate cavalry officer and leader of the cavalry battalion known as the Comanches. His farm was on the Virginia side of the ford.

Dickerson is an unincorporated community in Montgomery County, Maryland. It is on Maryland Route 28, between Sugarloaf Mountain and the Potomac River. It is a community near the town of Poolesville, Maryland. Dickerson is 61.5 square miles (159 km2).

Dickerson is a passenger rail station on the MARC Brunswick Line between Washington, D.C., and Martinsburg, WV (with an extension to Frederick, MD). This station was designed by E. Francis Baldwin and built by the Baltimore and Ohio Railroad in 1891. It is the last station Frederick bound trains pass before branching onto the Frederick Branch.

Heater's Island Wildlife Management Area is a Wildlife Management Area in Frederick County, Maryland. Heater's Island is a large forested island in the Potomac River near Point of Rocks, Maryland. It was long inhabited by the Piscataway people, who were forced to leave by smallpox in 1705.
