The Occoquan Reservoir and the Occoquan River dominate the northern and central landscape of this survey, serving as the border between Fairfax and Prince William counties. The terrain shows a suburban landscape in transition, where new developments like Dale City and Marumsco Village begin to spread across former rural tracts. Near the river, the town of Occoquan remains a focal point of infrastructure, featuring the Occoquan Dam, the Elk Horn Pumping Sta, and a large Filtration Plant.
