Occoquan River
Virginia Tributary
The Occoquan River, at 24.7 miles in length, is a major Virginia tributary of the Potomac. It forms the boundary between Fairfax and Prince William counties. The upper part of the river begins at the confluence of Broad Run and Cedar Run. Bull Run, a famous Civil War site, also joins the Occoquan River near Manassas. The river has three major dams, including the Occoquan Reservior, which is a major source of drinking water for Fairfax and Prince William Counties. The river flows into the Potomac at Belmont Bay, where it is lined with many marinas and waterfront facilities. The historic town of Occoquan is located near the upper end of the bay.
