On March 30, 2009, President Obama signed legislation designating the falls as Paterson Great Falls National Historical Park, which provides additional federal protections for the 77-foot waterfall
The Great Falls of the Passaic River is a National Historic Park surrounding a prominent waterfall, 77 ft (23 m) high, on the Passaic River in the city of Paterson in Passaic County in northern New Jersey in the United States. One of the United States' taller waterfalls, it played a significant role in the early industrial development of New Jersey starting in the earliest days of the nation. It is part of the Great Falls of Paterson-Garrett Mountain National Natural Landmark. It has also been a National Historic Landmark District since 1976.
During floods the Great Falls becomes a spectacular sight, with tremendous amounts of water cascading over the falls.
