Here is a map you can use to see just water features. The level of detail increases as you zoom in. The boundary lines have been deleted, as they often follow and obscure water features. It is interesting to trace the rivers to their headwaters.

In the north, the state's two largest river systems are the Passaic and the Raritan, which intertwine. In the south, the Mullica forms a sizable river system. Only one river originates in New Jersey and leaves the state - the Walkill in the north. All others are captured by either the Delaware or the Hudson, or the extensive southern bays. The orange line is approximately the dividing line between east (Hudson/Atlantic) and west (Delaware River) drainages. The red line is the "fall line" - the boundary between the Piedmont uplands and Atlantic coastal plain. And that's your lesson in hydrology.

The Raritan River is what is left of the outflow of the Hudson River after it broke through the Verrazano Narrows about 6,000 years ago and changed to its present course. The modern Raritan River drains much of central New Jersey, with tributaries threading through the state from Princeton to Morristown. One northern tributary - the Lamington River - reaches almost to Lake Hopatcong. Zoom the map out to see the entire drainage. The thin red line is the "fall line" - the nominal division between uplands and lowlands.
