Streamflow Network

The Current Period Streamflow Statistics project is computing low flow statistics for both a historic (1950-1979) and more recent (1990-2019) 30-year period. The computed statistics will provide information about streamflow changes over time and an evaluation of more recent streamflow conditions. The project will also present land-use changes, precipitation patterns, and water use in the...

StreamStats is a web application (Web Tool) for water-resources planning and engineering purposes. The map-based user interface can be used to delineate drainage areas for user-selected sites on streams, generate basin characteristics and estimate flow statistics for the selected sites. Users also can select the locations of USGS data-collection stations, shown as triangles on the StreamStats map...

Static webcams have been installed at a number of real-time stream-gaging locations in New Jersey to allow you to view the current river-stage conditions. These webcams provide valuable information to the National Weather Service, emergency managers, and area residents to evaluate real-time conditions in river environments during storms.

The USGS New Jersey Water Science Center streamgage program is part of the nationwide program that provides streamflow information for a variety of purposes—including the protection of life and property, infrastructure design, recreational usage, and long-term trend assessment. This information is critical to resource managers, farmers, fishermen, kayakers, land-use planners, engineers...

The accurate, long-term monitoring networks of New Jersey Water Science Center provide valuable data in real-time and historical perspective to compare that data to. The longer a monitoring location is in operation, the more valuable it becomes, since more statistical comparisons can be performed. Our field technicians continuously make field measurements and maintain these networks.

The USGS New Jersey Water Science Center, in cooperation with the NJ Department of Environmental Protection (NJDEP), New Jersey Water Supply Authority, and the Delaware River Basin Commission, maintain the New Jersey Ambient Surface-Water-Quality Monitoring Network (ASWQMN) — a collection of monitoring stations on streams throughout New Jersey. Constituent concentration data from the ASWQMN are...

Streamflow data collection and analysis are a necessary component of effective water resource management and planning. Low-flow statistics are needed to safely allow withdraws from and discharges to surface waters in the State of New Jersey. Operating streamflow gaging stations at every water use location would be ideal but is cost prohibitive. Statistics help extend the utility of available data...

The USGS will collect monthly water quality and quantity data from Neldon's Brook and Indian Brook in support of the Swartswood Lake and Watershed Association's (SWLA) development of a regional storm water management plan (RSWMP).

Federal, state and local agencies need flood-peak data for zoning, building permitting, and flood protection. Flood data needed are high-water elevations, flood discharges, and flood-frequency information. Stankowski in 1974 developed equations relating peak discharge to basin characteristics. Forty-six percent more station years of flood data are now available for analysis. Much of the additional...

To determine regional low-flow relationships for both the 2-year and 10-year 7-day low flows throughout New Jersey, so that accurate estimations of these values at ungaged sites can be made
