Groundwater Watch


USGS Groundwater Watch

The USGS has a distributed water database that is locally managed. Surface water, groundwater, and water quality data are compiled from these local, distributed databases into a national information system. The groundwater database contains records from about 850,000 wells that have been compiled during the course of groundwater hydrology studies over the past 100 years. Information from these wells is served via the Internet through NWISWeb, the National Water Information System Web Interface. NWISWeb provides all USGS groundwater data that are approved for public release. This large number of sites is excellent for some uses, but complicates retrievals when the user is interested in specific networks, or wells in an active water-level measurement program.

These "groundwater watch" web pages group related wells and data from these active well networks, and provide basic statistics about the water-level data collected by USGS water science centers for Cooperative Programs, for Federal Programs, and from data supplied to us by our customers through cooperative agreements.
National Networks
Active Groundwater Level Network
Active Groundwater Level Network

Contains water levels and well information from more than 20,000 wells that have been measured by the USGS or USGS cooperators at least once within the past 13 months.
 
Below Normal Groundwater LevelsClimate Response Network
Below Normal Groundwater Levels

Contains water levels from wells where the most recent water-level is in the 24th percentile or lower of the period of record statistics
Climate Response Network

A network of wells to monitor the effects of droughts and other climate variability on groundwater levels
 
Real-Time Groundwater Level NetworkLong-Term Groundwater Data Network
Real-Time Groundwater Level Network

A network of wells that transmit water levels to USGS offices every 1 to 4 hours, depending on the data relay technique used
Long-Term Groundwater Data Network

Actively-measured periodic, continuous, and/or real-time wells with at least 20 years of measurements
 
Regional Networks

State and Local Networks

High Plains Aquifer Monitoring Network
High Plains Aquifer Monitoring Network

A network of wells from selected wells measured annually by the USGS and numerous Federal, State, and local water-resources agencies
New Jersey Groundwater Level NetworkNew Jersey Groundwater Level Network
Piedmont and Blue Ridge Aquifer Groundwater Network
Piedmont and Blue Ridge Aquifer Groundwater Network

A network populated by wells completed in the Piedmont and Blue Ridge crystalline-rock aquifers. Network wells have been measured at least once within the past 13 months, regardless of measurement frequency or the monitoring objective.
