NEW JERSEY FLOW REPORT

Last Updated: February 9, 2026

The streamflow conditions across New Jersey's rivers have shown significant variability, with several waterways reporting lower than average flows, which could impact recreational activities and ecological balance. Notably, the Delaware River at Belvidere, a critical waterway for the region, is flowing at 2,840 cubic feet per second (cfs), a considerable 75.28% below the seasonal norm and could affect the local ecosystems and communities reliant on this river. The Toms River near Toms River and the Passaic River at Pine Brook are also experiencing reduced streamflows of 54.64% and 81.36% below normal, respectively, indicating potential flow droughts that may concern anglers and paddlers looking for sufficient water levels.

In contrast, the Raritan River at Manville has seen a substantial 24-hour increase in streamflow of 86.96%, with a current flow of 473 cfs, raising concerns for potential localized flooding, especially if this trend continues. The Delaware and Raritan Canal at Port Mercer, important for both its historical value and as a recreational waterway, shows a slight increase in flow, currently at 149 cfs, which is 4.41% above normal and could be advantageous for water enthusiasts. The Delaware River, crucial for its whitewater trails, presents mixed conditions with the station at Montague registering a minor increase in flow, while that at Trenton notes a slight decrease. River users, including those in significant cities such as Trenton and those frequenting popular trails, should stay informed about current conditions and any advisories, especially with the observed fluctuations and anomalies in streamflow data.
