NEW JERSEY FLOW REPORT

Last Updated: December 22, 2025

New Jersey's river systems have exhibited a variety of streamflow trends, with several waterways reporting notable deviations from normal flow levels. The Delaware River, a major watercourse traversing the state, has shown mixed conditions, with the Delaware River at Montague reporting streamflows at 6760 cubic feet per second (cfs), about 23.26% below normal, while downstream at Trenton, the streamflow has increased by 43.64% over the past 24 hours to 15800 cfs, which is still approximately 9.21% below the seasonal norm. This surge can potentially impact areas along the river, although it is not yet indicative of flooding. Assunpink Creek and the Musconetcong River, important for local ecosystems and recreational activities, also report lower than normal flows, at 45.27% and 32.88% below normal, respectively. Such patterns may influence river-based activities, including whitewater trails in these regions.

Cities such as Trenton on the Delaware River and Millington and Chatham along the Passaic River should be aware of streamflow patterns as they can affect water availability and potential flood risks. The Passaic River near Millington and Little Falls has experienced significant reductions in streamflow, indicating possible flow drought conditions that could affect local water supplies. Conversely, rivers like the Toms and Great Egg Harbor show smaller variations from the norm, which might offer more stable conditions for river enthusiasts. It's important for water enthusiasts and stakeholders to stay updated on these trends since streamflow changes can signal environmental impacts, influence water-based recreation, and alter flood risk profiles in communities near these rivers and streams.
