Historic River Maps
Our friends at Fort Egypt in Page County have assembled a great collection of early maps including James Herron’s 1832 trace of the river. Some of their image files are quite large but well worth viewing. Visit the Fort Egypt website to see them all.

Smith Creek information
The following report is big, dense, and fascinating. Smith Creek is an agricultural tributary of the North Fork and is one of several “showcase” watersheds in the Chesapeake undergoing extensive research and restoration efforts. Lessons about nutrients, groundwater, and sediment in Smith Creek may be applicable to much of the Shenandoah.
