NEW JERSEY FLOW REPORT

Last Updated: December 29, 2025

Streamflow conditions across New Jersey's rivers and streams show a noteworthy decrease from typical levels for this period, with several key waterways such as the Delaware River and Passaic River reporting significantly reduced streamflow. At the Delaware River at Montague, the current streamflow is 3,790 cubic feet per second (cfs), which is approximately 60% below normal for this location. Similarly, at Trenton, the flow is 5,200 cfs, marking a significant 75% departure from the expected value. Low flows have also been recorded at the Passaic River, with the gauge at Pine Brook showing a flow of 277 cfs, nearly 75% below normal, and the Little Falls location showing a 311 cfs flow, a drastic 87% below average. These reduced streamflows could affect recreational activities such as fishing and whitewater paddling, particularly in popular spots like the Delaware Water Gap and along the Raritan River.

Notably, the North Branch Raritan River near Raritan experienced a sharp 92.79% increase in flow over the last 24 hours, although it remains 82% below normal levels, which suggests the presence of localized rainfall or runoff events. Despite these changes, the overall trend indicates a period of lower-than-average water availability, which could lead to flow droughts in parts of New Jersey. Cities and regions such as Trenton, Pine Brook, and Little Falls may need to monitor water resources closely. Meanwhile, the Delaware and Raritan Canal at Port Mercer shines as an outlier with a current streamflow 17% above normal, which may draw attention from water enthusiasts looking for more reliable conditions. However, with most streams and rivers reporting low levels, conservation and cautious water use are advised until conditions return to normal.
