USGS Groundwater Watch *

* Note: This is an interim version of Groundwater Watch. The first generation of Groundwater Watch relied on servers that were subject to a mandatory shutdown on September 30, 2019. The mandatory transition off of these servers is government-wide, and is related to national security issues.

In order to continue Groundwater Watch operations after September 30, 2019, USGS Water Resources Mission Area migrated Groundwater Watch off of non-compliant servers. Because of limitations of the software components and the underlying hardware, the migration to the new infrastructure required a reduction in the number of networks served. The Groundwater Watch team, working with Water Science Centers, identified the networks that will be maintained on GWW during this transition.

We recognize that the reduction in available networks will impact USGS partners and other GWW users. In the future, the resources available for development of groundwater network delivery will focus on evaluating and re-designing map-based displays of groundwater data into contemporary products for serving value-added groundwater data.
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 NetworkClimate Response NetworkReal-Time 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.
Climate Response Network

A network of wells to monitor the effects of droughts and other climate variability on groundwater levels
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
 
Below Normal Groundwater Levels
Active Spring Monitoring Sites
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
Active Spring Monitoring Sites

The Active Springs Monitoring Sites web pages provide data from more than 100 springs in the active measurement program of the U.S. Geological Survey across the nation.
