CourseEdit
The headwaters of the stream originate in the city of Rockville, and the branch flows southwest for 11.2 miles (18.0 km), under the C&O Canal near Swain's Lock, to the Potomac River, which drains to the Chesapeake Bay. The watershed area is about 22 square miles (57 km2).
Portions of Watts Branch flow through a stream valley park, a mostly undeveloped natural area which acts as a riparian buffer zone to help minimize stream bank erosion and filter pollutants from stormwater runoff.
Development impacts on water qualityEdit
While some parts of the Watts Branch watershed are parkland or remain forested, the area is adjacent to Rockville town center and the Interstate 270 corridor. This community has experienced extensive residential and commercial development over the past several decades. Population in the Rockville city limits (of which only a portion is in the Watts Branch watershed) doubled between 1960 and 2003, from approximately 26,000 to 52,000. These development trends have led to degraded water quality due to stormwater pollution in some portions of the Watts Branch mainstem and tributaries. The stream and watershed have been the subject of extensive studies and planning by Montgomery County and the City of Rockville. A number of stream restoration projects have been undertaken by both governments. In order to preserve water quality in a partially developed area, the county has imposed some restrictions on development (i.e. designation of a "Special Protection Area") in part of the Piney Branch sub-watershed.
