Watts Branch is a 22 square mile watershed that drains into the Potomac River. The headwaters of Watts Branch, approximately 16 miles of stream, originate in the western half of the City of Rockville. Due to impacts of development and stormwater runoff, Watts Branch is experiencing increased erosion, which releases excess sediment and other pollutants that contribute to poor water quality in the stream, the Potomac River, and ultimately the Chesapeake Bay. In addition, this erosion threatens public infrastructure, trails and forest and wetland habitat. The Upper Watts Branch Park Forest Preserve Environment Restoration Project will enhance the Watts Branch watershed through stream restoration, stormwater management, wetland enhancement, reforestation and protection of public utilities.
