Ground Water Information for Idaho

Ground Water Data

Active Ground-Water Level Network

The Active Ground-Water Level Network contains water levels and well information from 871 wells in Idaho that have been measured by the USGS or USGS cooperators at least once within the past 365 days. This network includes all of these wells, regardless of measurement frequency, aquifer monitored, or the monitoring objective.

Real-Time Ground-Water Level Network

Real-time data typically are recorded at 15-60 minute intervals, stored onsite, and then transmitted to USGS offices every 1 to 4 hours, depending on the data relay technique used. Recording and transmission times may be more frequent during critical events. Data from real-time sites are relayed to USGS offices via satellite, telephone, and/or radio and are available for viewing within minutes of arrival. Please note, however, that all real-time data are provisional and are subject to revision.

National Water Information System Web Interface (NWISWeb)

The USGS maintains a database/archive of about 850,000 wells across the Nation. Information about these wells is available to the world via NWISWeb. Through various ground-water programs, the USGS actively measures water levels in about 20,000 of these wells each year. These wells are measured for a variety of disparate purposes, such as statewide monitoring programs, or more local effects like monitoring well drawdown, hydrologic research, aquifer tests, or even earthquake effects on water levels.
