USGS New Jersey Water Science Center home page

Welcome to the New Jersey Water Science Center web page. This is your direct link to water-resource information on New Jersey's rivers and streams, groundwater, water quality, and biology. Data collection and interpretive studies are done by the Center to support state-wide water-resource infrastructure and management needs and are part of the USGS science strategy to address the water-resource priorities of the nation and global trends in:

Ecosystem status and change
Climate variability and change
Energy and mineral management
National hazard risk and assessment
Environmental risk to human health
Water use and availability

USGS StreamMail

Use the USGS system to request real-time stream stage and flow data by email from your computer, cell phone or Blackberry. Send an email to streammail@usgs.gov and in the "Subject" line, put in a USGS station (site) number. In a few minutes, you'll get back an email with the most recent stream stage and flow.

NJ Water Sciences

The USGS New Jersey Water Science Center monitors and analyzes surface-water, groundwater, water-quality and biological parameters throughout the state. Data collection and interpretive studies are done in cooperation with various local, State, or Federal agencies.

Surface Water

New Jersey provides real-time water-stage and streamflow data at over 140 sites across the state. Flood prediction, stream low-flow characteristics and surface-water quality are currently under investigation in 28 studies.

Groundwater

New Jersey maintains a long-term water-level monitoring network of 192 wells. Real-time water-level data is available at 22 of these wells. Over 30 current groundwater investigations evaluate groundwater-supply and groundwater-quality issues.

Water Quality

Water-quality conditions are continuously monitored by the USGS at 42 real-time sites across the state of New Jersey. Water-quality issues in groundwater and surface-water are addressed in over 30 current interpretive studies.

Biology

Interpretive studies based on periodic monitoring address aquatic life impairments resulting from the impact of hydrologic stresses.

Featured Project

StreamStats - New Jersey

Map of Eco Flow Sites

StreamStats for New Jersey can be used to estimate instantaneous flood discharges with exceedance probabilities of 0.5, 0.2, 0.1, 0.04, 0.02, 0.01, 0.005, and 0.002 for ungaged, unregulated, rural streams. These exceedance probabilities correspond to recurrence intervals of 2-, 5-, 10-, 25-, 50-, 100-, and 500-years, respectively. The report below presents the regression equations used to estimate the peak-flow statistics, describes the errors associated with the estimates, and describes the methods used to develop the equations and to measure the basin characteristics used in the equations. Users should familiarize themselves with the report before using StreamStats to obtain estimates of streamflow statistics for ungaged sites.
