New Jersey Water Science Center Webcams

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.

Groundwater Response to Earthquakes

Did you know? Earthquakes can affect groundwater levels?

We often see a response to large (and sometimes not so large) earthquakes in groundwater levels in wells. The USGS maintains a network of wells for monitoring various things like natural variability in water levels and response to pumping and climate change across the U.S.

USGS Data Delivery Tools

USGS WaterAlert allows users to set notification thresholds for any USGS real-time data collection station, including stream, tidal, and groundwater gages, water-quality, and weather stations and sends emails or text messages to subscribers whenever the threshold conditions are met, as often as every hour.

Floods: Recurrence intervals and 100-year floods

How do we know or measure if a flood that could happen tomorrow is worse than one that happened 2, 10 or 50 years ago? If heavy rain is being forecasted does that mean that rivers are going to rise and spill over their banks and flood your neighborhood? These are some of the questions that many of us think about when flooding or heavy rain is forecast by the National Weather Service (NWS) or...

Hurricanes and Storm-Tide Monitoring

The USGS works in partnership with other federal and state agencies to provide scientific data about coastal flood hazards. The New Jersey Water Science Center (NJWSC) maintains a network of continuously operating tide gages along the back bays of New Jersey which provide publicly available water-level and meteorological data to monitor coastal flood conditions.  The USGS NJWSC...

Earthquake Resources

Earthquakes felt in New Jersey are generally few and small. However, some earthquakes have produced damage in New Jersey. New Jersey’s seismic hazard is lower than many earthquake-prone parts of the United States.  Across the state, seismic hazards are highest in northeastern New Jersey.

Flood Resources

The USGS reports document New Jersey floods from 1896 to the present. Early spring and winter flooding in New Jersey tends to occur as a result of widespread, steady rain of moderate intensity that falls on frozen ground. Snow and ice melt may increase the chance of winter flooding. Summer flooding resulting from thunderstorms typically occurs in small streams and is of local extent. Late...
