The Chiques Creek Watershed covers approximately 126 square miles of area, nearly all of which is within Lancaster County.  Beginning in Lebanon County, the Chiques Creek flows 31 miles to its confluence with the Susquehanna River near Marietta Borough.  Six townships (East Hempfield, Mount Joy, Penn, Rapho, West Cornwall & West Hempfield) and two boroughs (Manheim & Mount Joy) have areas contained within the watershed.  This is testament to the fact that natural divides such as watersheds do not respect man-made boundaries.
