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 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 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 Darby Store, also known as the Darby Store Cultural Park is a historic site located on Medley's Hill at 19801 Darnestown Road in Beallsville, Maryland that is part of the Beallsville Historic District. What is now the intersection of Beallsville Road and Darnestown Road/(Route 28) was formerly the Brewer Farm. In 1908, H.C. Darby bought the land. In 1910, H.C. Darby built a two-story general store. In the 19th and 20th century it was very common to have the family residence next to the family business, and the Darby House was built in 1921.In 2004, the Maryland-National Capital Park and Planning Commission purchased the property and restoration by BELL Architects was ongoing through 2015. The general store is culturally and historically significant as one of the few remaining examples of rural vernacular architecture of the early 20th century in Montgomery County. During the summer of 2009, the site was under excavation. A team of archaeologists spent three weeks at the site and their findings included: oyster shells, glass shards, coal, nails, ceramic pipe stems, a 1918 liberty dime, and a Yoo-hoo bottle, all of which provide clues to the history of the area, and the buildings occupying it since the 19th century.

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.
