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.
