NEW JERSEY FLOW REPORT

Last Updated: December 25, 2025

The state of New Jersey is currently experiencing a noticeable decline in streamflows across its major rivers and watersheds, indicating a trend towards flow drought conditions. The Delaware River, a critical waterway that supports diverse recreational and ecological needs, shows a significant reduction in streamflow at key points including Montague, Trenton, and Belvidere, with current measurements at 4030 cubic feet per second (cfs), 8430 cfs, and 5580 cfs respectively, all notably below normal ranges by 59.97%, 57.4%, and 58.66%. Such low streamflows may affect popular whitewater trails and could potentially impact water availability for surrounding communities.

In addition to the Delaware River, other tributaries and rivers such as the Musconetcong, Maurice, and various branches of the Passaic and Raritan Rivers report alarming decreases in flow rates, with the Passaic River at Little Falls and the North Branch Raritan River near Raritan displaying streamflows that are 75.31% and 82.59% below normal, respectively. These conditions are not only concerning for local ecosystems but also for residents in nearby areas such as Trenton, Chatham, and Bound Brook who rely on these rivers. The low streamflow data, coupled with significant negative changes in gage heights within the past 24 hours, suggest an urgent need for water conservation efforts and a close monitoring of the situation for signs of potential drought stress or, conversely, flood events should there be a rapid increase in streamflow. River and water enthusiasts should remain attentive to the latest flow data and advisories from local water management authorities when planning activities.

       



New Jersey's hydrology is characterized by a humid climate, with frequent precipitation and abundant water resources. Two major surface flows, the Delaware River and the Hudson River, comprise New Jersey's eastern and western borders respectively. The state has numerous reservoirs and dams that are used for water supply, flood control, and recreation. The largest reservoirs include Round Valley Reservoir and Wanaque Reservoir. The state's major rivers and tributaries include the Passaic River, Raritan River, and Hackensack River, which all flow into the Atlantic Ocean. The state's watershed data indicates that the state experiences variable rainfall and snowpack, with some areas experiencing drought conditions while others are prone to flooding. Overall, New Jersey's hydrology is complex and influenced by a range of factors, including climate variability and anthropogenic activities.
