The Philadelphia District maintains more than 550 miles of navigable waterways in the Delaware River Valley. We own and maintain the Chesapeake & Delaware Canal and the 6 six bridges that cross it. The District nourishes beaches in New Jersey and Delaware to reduce storm damages. We operate 5 dams in eastern Pennslyvania that have prevented millions of dollars in floods damages. We also execute a number of smaller projects under the Continuing Authorities Program.
