The Academy of Natural Sciences (Philadelphia) hosts this page on Urban Rivers Awareness. Offering information both general (e.g., the importance of water and watersheds) and specific (e.g., Manatwany Creek dam study), the site introduces viewers to urban river issues via an ecological study on the removal of a dam in Pennsylvania. Site content is directed towards raising awareness of urban rivers and is educational in flavor. Also at the site is a series of links to other Academy projects, external resources, and related articles.
