Groundwater and Streamflow Information Program
Programs L2 Landing Page
The Groundwater and Streamflow Information Program (GWSIP) is one of four Water Investigations Programs funded by Congress to identify, measure, and assess the Nation’s water resources. The GWSIP is the principal USGS Program for monitoring groundwater and streamflow, including floods and droughts, related to groundwater resources at the regional/national scales.
Blaine County’s population nearly quadrupled from about 5,700 to 22,000 people between 1970 and 2010. Residents and resource managers of the Wood River Valley of south-central Idaho are concerned about the potential effects that population growth and the expected increased demand for water might have on the quantity and quality of the valley’s ground and surface waters. Increased water use has...
These assessments will document the effects of human activities on water levels, groundwater storage, and discharge to streams and other surface-water bodies; explore climate variability impacts on the regional water budget; and evaluate the adequacy of data networks to assess impacts at a regional scale.
At the core of NSIP will be a set of USGS-funded streamgages strategically positioned across the country that are continuously operated to fulfill five Federal needs for streamflow information. These will be a permanent set of core streamgages from which streamflow information would be delivered in real time, uncompromised by changing support from funding partners.
Measurements of groundwater levels from wells are used to monitor changes in groundwater conditions due to climate variability and withdrawals (pumping). The GWRP has supported the development of a Groundwater Climate-Response Network, a network of wells selected to illustrate the response of the groundwater system to climate variations nationwide.
USGS conducts research into new and emerging geophysical methods and applications for groundwater investigations. Near-surface geophysical techniques can be used to rapidly and effectively characterize the shallow subsurface and to monitor hydrologic and remediation processes in ways not previously possible with standard technology.
