Little Falls Branch, Stream tributary in Montgomery County, United States.
Little Falls Branch extends 3.8 miles through Montgomery County, flowing under the C&O Canal before joining the Potomac River at Little Falls rapids.
The stream, formerly known as Powder Mill Branch, supplied water to Washington DC through reservoirs until the Washington Aqueduct construction in the 1800s.
The Little Falls Watershed Alliance organizes over 40 annual volunteer events, connecting residents with environmental conservation activities throughout the stream valley.
Visitors can access the stream through Little Falls Stream Valley Park, which contains 160 acres of natural areas and walking paths.
The stream marks the beginning point of the tidal Potomac River system, flowing through culverts that represent early American water management engineering.
