Passaic River
The Passaic River ( pə-SAY-ik or locally pə-SAYK) is a river, approximately 85 miles (137 km) long, in northern New Jersey. The river in its upper course flows in a highly circuitous route, meandering through the swamp lowlands between the ridge hills of rural and suburban northern New Jersey, called the Great Swamp, draining much of the northern portion of the state through its tributaries.
