The Bull Run Watershed Management Unit dominates the central landscape of this 1990s survey, a strictly protected area that secures the regional water supply. This hydrological focus is visible through an intricate network of infrastructure, including the Bull Run Reservoir No 2, the Flume leading from the Bull Run River, and the Marmot Dam situated along the Sandy River. The map reveals the intersection of industrial utility and recreational or community sites, such as Camp Namanu and Camp Howard, positioned near the western boundary. Settled areas like Aims and Cherryville anchor the periphery, while the Devils Backbone ridge provides a prominent natural landmark. For researchers, the inclusion of the Bull Run (Site) and various gaging stations illustrates the long-standing management of these river systems before modern alterations to the hydraulic landscape.
