The Delaware’s main tributaries in New York are the Mongaup and Neversink Rivers and Callicoon Creek; in Pennsylvania, the Lackawaxen, Lehigh, and Schuylkill Rivers feed the Delaware; and from New Jersey, the Musconetcong, Rancocas Creek and the Cooper and Maurice Rivers.
The upper part of the Delaware is shallow and difficult to navigate, so a canal system was built. Opened in 1830, it ran from Easton to Bristol, just beneath the Trenton Falls. It is no longer used for shipping, but the canal is still a source of enjoyment and recreation for thousands of visitors every year who walk and bike along its towpath.
