Gazing at the Passaic River, it’s hard to imagine this waterway as anything other than the bustling, urban river it is today. The Passaic River has a rich, complex history. It has played a crucial role in shaping the landscape and the lives of the people who have lived along its banks. The Passaic River begins its 80-mile journey in the quiet hills of Mendham, New Jersey, eventually flowing into Newark Bay and the greater New York-New Jersey Harbor Estuary.
The Passaic River basin encompasses a remarkable range of environments. From the pristine headwaters in the Highlands, to the suburban wetland complexes of Morris County, to the densely populated, and historically contaminated, lower reaches, the Passaic River has seen it all. The river’s journey starts modestly enough, with small tributaries feeding into it as it meanders through the protected lands of Jockey Hollow National Historic Park and the Great Swamp National Wildlife Refuge. Then, the river’s course becomes more defined, carving a path between counties, and growing in size as it’s joined by significant tributaries like the Rockaway and the Pompton. The Pompton River itself is a major waterway, fed by the waters of the Ramapo, Pequannock, and Wanaque Rivers, which originate in the Highlands and supply drinking water to millions.
As the Passaic River continues its journey, it takes on a decidedly urban character. Passing through Little Falls and Paterson, it tumbles over the Great Falls, a dramatic 70-foot drop. This natural wonder was a key factor in Paterson’s early industrial development. The river powered the mills that once dominated the city’s landscape. Further downstream, Dundee Dam in Garfield marks a significant point in the river’s flow. This dam acts as a barrier to the tidal currents from Newark Bay, preventing contaminated sediments from traveling further upstream. It also forms Dundee Lake.
Sadly, the lower Passaic River bears the scars of industrialization. The 17-mile stretch between Dundee Dam and Newark Bay is particularly burdened by contaminated sediments, a legacy of dioxin discharge from the production of Agent Orange in the 1960s. Efforts to remediate this area are ongoing, a testament to the enduring impact of industrial activity on the river’s health. While pollution is a significant challenge, flooding also poses a constant threat to communities along the Passaic River, particularly in areas where development has encroached upon the floodplain. The Passaic River Flood Tunnel, a proposed 20-mile structure, is one potential solution to mitigate this recurring problem.
Despite its environmental challenges, the Passaic River remains a vital part of the region’s identity. It has witnessed centuries of change, from Native American fishing weirs to industrial mills to modern revitalization efforts. The river’s history is etched into the surrounding landscape. The remnants of industry and the ongoing struggle for environmental restoration serve as reminders of its complex and ever-evolving story. The Passaic River’s journey is a microcosm of the challenges and triumphs of human interaction with the natural world. From its peaceful beginnings to its industrialized present, the Passaic River remains a powerful force shaping the lives and landscapes of northern New Jersey.
