The U.S. Geological Survey WaterAlert service sends e-mail or text (SMS) messages when certain parameters, as measured by a USGS real-time data-collection station, exceed user-definable thresholds. The development and maintenance of the WaterAlert system is supported by the USGS and its partners, including numerous federal, state, and local agencies.

How We Monitor Stream Temperature in the Delaware River Basin

The USGS has been monitoring stream temperature in the Delaware River Basin since 1901, and has amassed over 650,000 daily temperature measurements. This data visualization story explores temporal and locational patterns in stream temperature observations, and how spatial variability and data gaps add complexity to prediction efforts.

Water science and management in the Delaware River Basin (data visualization story)

The Delaware River supports thriving ecosystems and drinking water for 16 million people. How water is shared, and the quality of that water, has been the focus of decades of inter-state discussion, negotiation, and research. This data visualization story uses streamflow, salinity, and temperature to show how new USGS science and monitoring can inform water management in this age of...

New Jersey Coastal Plain Water-Table

The series of surficial aquifer studies were completed to evaluate the unconfined aquifer system of the NJ Coastal Plain for use as a potential source of water. As the demand for water in the State increases and the restrictions continue on the use of water from certain confined aquifers, withdrawals on the unconfined aquifer system are expected to increase.

Daily-timestep and monthly-timestep estimates of baseflow at 49 reference stream gages located within 25 miles of the Delaware River basin watershed boundary for the years 1950 through 2015

This USGS data release contains daily-timestep and monthly-timestep estimates of baseflow at 49 reference stream gages located within 25 miles of the Delaware River basin watershed boundary. Estimates are provided for the available period of record of streamflow data at each site between 1950 and 2015. A two-parameter recursive digital filter was used to estimate baseflow at the selected...

Estimated low-flow statistics at ungaged stream locations in New Jersey, water year 2019

Estimates of various low-flow statistics were computed at 53 ungaged stream locations throughout New Jersey during the 2019 water year using methods in the published reports, 1) Streamflow characteristics and trends in New Jersey, water years 1897-2003 (Watson and others, 2005) and 2) Implementation of MOVE.1, censored MOVE.1, and piecewise MOVE.1 low-flow regressions with appli
