Key Aspects of the Passaic River
Key Takeaways
- The Passaic River is a major northern New Jersey waterway, approximately 80 miles long.
- Its unique “backward” flow (south then northeast) and low-lying, developed areas make it prone to severe flooding.
- Paterson, home to the Great Falls, was a pivotal industrial hub thanks to the river’s hydropower.
- Numerous cities and towns, including Newark, Clifton, and Wayne, are part of its extensive basin.
- Flood control, notably the proposed Passaic River Flood Tunnel, is a long-standing and complex challenge.
- Historical industrialization has left a legacy of environmental contamination, particularly with dioxin.
- The river eventually drains into Newark Bay, which connects to Upper New York Bay.
