Shenandoah River

The Shenandoah River is a tributary of the Potomac River, 55.6 miles long with two forks approximately 100 miles long each, in the U.S. states of Virginia and West Virginia. The principal tributary of the Potomac, the river and its tributaries drain the central and lower Shenandoah Valley and the Page Valley in the Appalachians on the west side of the Blue Ridge Mountains, in northwestern Virginia and the Eastern Panhandle of West Virginia.
The Shenandoah River is formed northeast of Front Royal near Riverton, by the confluence of the South Fork and the North Fork. It flows northeast across Warren County, passing underneath Interstate 66 1 mile from its formation. Beyond the I-66 bridge the river flows through a set of bends before turning to the northeast again, crossing into Clarke County 11 miles below I-66. Five miles downriver from the Clarke County border, the Shenandoah passes under U.S. Route 50 and then passes through a triple bend. 14.5 miles below the Route 50 bridge, the river passes underneath State Route 7 and then continues northeast another 8 miles where it crosses into Jefferson County in West Virginia. Once in West Virginia the river completes six large bends before joining with the Potomac from the southwest near Harpers Ferry. The confluence is on the West Virginia-Maryland border and 0.4 miles from the Virginia-West Virginia border.
