A part of the Shenandoah River basin, the North Fork Shenandoah watershed (Watershed ID VAV-B45R) is located in Rockingham and Shenandoah Counties, Virginia, and comprises the following watershed IDs B42, B43, B44, B45, B46, B47, B48, B49, and B50. Of those watersheds, three have existing TMDLs: B46-Linville Creek, B47-Smith Creek, and Holmes Creek (part of B45). A section of B42 lies within West Virginia. The North Fork Shenandoah is loosely bounded by the county boundaries to the west and the Massanutten Mountains to the east (See Figure). Harrisonburg lies on the southern boundary and Woodstock is near the northern boundary. The watershed is approximately 454,000 acres in size. North Fork Shenandoah is heavily forested (about 61%) followed by agricultural (about 37%) with the remaining residential (about 2%). The watershed flows north and discharges into the Shenandoah River (USGS Hydrologic Unit Code 02070006), which flows into the Potomac River; the Potomac River discharges into the Chesapeake Bay.
A part of the North Fork Shenandoah watershed, the Stony Creek watershed (Watershed ID VAV-B49R) is located in Shenandoah County, Virginia, loosely bounded by Appalachian Mountains to the west, and Edinburg to the east (See Figure). The Stony Creek watershed is approximately 72,600 acres in size. Stony Creek is mainly a forested watershed (about 70%) within the Appalachian Mountains into the rolling valley. The remaining 30% of the watershed area is primarily agricultural (28%), with a small area devoted to rural developments (2%).
