Warm Springs Run flows for 11.8 miles through the heart of Morgan County, WV to the Potomac River. The stream flows through low density residential, urban residential, industrial, commercial, and relatively natural areas. Diverse land use patterns have varied impacts on water quality in Warm Springs Run and ultimately in the Potomac River. The Run originates just south of the Ridersville Cycle Shop on Rt 522, 4 mi. S of Berkeley Springs (GPS approx. 39.573940, -78.257534). It empties into the Potomac River just downstream of Hancock, north of the Potomac Airpark (GPS approx 39.695605, -78.172351)
