The Patapsco and Back Rivers watershed drains 630 square miles. This area includes Baltimore, and portions of Anne Arundel, Baltimore, Carroll, and Howard Counties. The area is very populated and urbanized. The census population in 2000 for the watershed was 1,480,000. Baltimore is the largest city in the watershed, with suburbs of the city extending out from it in every direction. Other large cities include Westminster, Ellicott City, Towson, and Glen Burnie. There are seven major wastewater treatment plants in the watershed. (Based on MD DNR Tributary Strategy Report by Karrh et al., 2007 and updated 2000 land use classifications).
