Delaware River: The Delaware River is one of the large rivers of the United States, and forms the natural drainage for portions of the States of Pennsylvania, New York and New Jersey. The minimum rate of flow of upland water during a month of extreme drought is at a rate of 2,030 second feet; the normal flow during months free from freshet or drought is at a rate of 4,050 second feet. There is a tidal range of 5-1/2 feet, and it is estimated that during the ebbing of the tide 2,421,000,000 cubic feet of water flow past the city. The accompanying view was taken from the east or New Jersey side of the Delaware River, and inadequately portrays the size of the river, which is about 2,000 feet wide at this cross section.
