of the two, owing mostly to the fact that a large portion of it runs through wilderness, making for very fine smallmouth bass, warmouth and rock bass fishing. However, there are a few small sewage treatment plants on the lower West Branch, starting at Fort Loudon, that make the lower West Branch less hospitable to native species' spawning. Northern pike and pickerel have been caught in the creek. The West Branch flows southwest along the Tuscarora Trail to around Fort Loudon, then turns south, and finally southeast, joining the main stem north of the Mason–Dixon line. The Bridge in Metal Township crosses the West Branch Conococheague Creek at Metal Township in Franklin County, Pennsylvania. It was listed on the National Register of Historic Places in 1988. Main stem below the West Branch Conococheague Creek continues south into Maryland and enters the Potomac near Williamsport, where the Great Philadelphia Wagon Road crossed the river at William's Ferry, continuing on to Winchester, Virginia. The crossing is where Braddock's forces crossed the Potomac after leaving Frederick on their way to Winchester. The Tuscarora Trail crosses the Conococheague.
