WatershedEdit
The watershed in Montgomery County includes portions of the communities of Norwood, Bel Pre Manor, Colesville, Layhill, Glenmont, Wheaton, Hillandale, White Oak, Silver Spring, Kemp Mill, Four Corners and Takoma Park. The Prince George's County portion of the watershed includes Adelphi, Langley Park, University Park, Chillum, Hyattsville, Avondale and Brentwood. The total watershed area, including a small portion of land in Washington, D.C., is 53.5 square miles (139 km2), with a resident population of about 254,000.
The middle section of the Northwest Branch is referred to as the Rachel Carson Environmental Area. It flows through a small gorge underneath the Capital Beltway between Colesville Road and Adelphi Mill. Located at the north end of the Northwest Branch Trail, near the home of noted environmental author Rachel Carson, it is deliberately left rustic and unimproved.
The majority of the Northwest Branch stream valley is a riparian buffer, protected as parkland by the Maryland-National Capital Park and Planning Commission (M-NCPPC). The Rachel Carson Greenway planned by M-NCPPC will extend the Northwest Branch Trail into northern Montgomery County as an unimproved hiking trail, connecting to the Anacostia Tributary Trail System in Prince George's County.
GeologyEdit
Northwest Branch crosses the geological fall line between the Piedmont and Atlantic coastal plain regions, which forms a small waterfall on the stream near White Oak.
