NEW JERSEY FLOW REPORT

Last Updated: December 24, 2025

New Jersey's streamflow report reveals a statewide pattern of decreased water levels in major rivers, suggesting a period of low water conditions that could affect recreational activities and water resources management. The Delaware River, a vital waterway for the region, exhibits a significant drop in streamflow, with the Montague and Trenton monitoring stations reporting flows of 4460 cfs and 10200 cfs respectively, which are well below normal ranges, at approximately 43% and 53% of typical levels. Similarly, other key rivers such as the Musconetcong, Raritan, and Passaic reflect notable reductions in flow, with the Passaic River near Little Falls showing a drastic decrease to 695 cfs, a mere 30% of its normal flow. The low streamflow levels, coupled with the downward trend observed over the last 24 hours, could impact local ecosystems, water supplies, and the enjoyment of river-related activities such as fishing and kayaking, particularly on popular whitewater trails in these areas.

Whitewater enthusiasts and nature observers should take note of the current low water conditions, as they may affect accessibility and safety on New Jersey's rivers. The Delaware River at Belvidere, an area frequented for its recreational opportunities, is currently flowing at 6290 cfs, around half of its typical streamflow, which may alter the difficulty and character of whitewater runs. Likewise, smaller rivers such as the Maurice and Toms, crucial for local biodiversity and recreation, are also experiencing diminished flows. The Maurice River at Norma stands at 121 cfs, and the Toms River near Toms River is at 208 cfs, both significantly below their normal levels. These streamflow changes, particularly if they persist or intensify, could signal potential environmental stress and warrant attention from water resource managers and local communities to address any potential long-term impacts on water availability and river health in New Jersey.
