Data & Information
One of the goals of the USGS Groundwater Resources Program (GWRP) is to identify, describe, and make available fundamental information regarding groundwater availability in the Nation's major aquifer systems:
Groundwater Level Data
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.
The Climate Response Network Web site is part of the USGS Groundwater Watch web site, which is the official USGS Web site for illustrating current groundwater conditions in the United States and Puerto Rico.
Regional Evaluations of Groundwater Levels
The GWRP also supports the regional evaluations of groundwater levels in areas of the country where groundwater resources have undergone intensive development. Recent examples include:
Large amounts of digital water resources data are generated as part of USGS efforts to holistically assess the Nation's groundwater. Regional groundwater availability studies are currently taking place to document the supply and demand of this important natural resource for the United States. It is essential to document the status and trends in groundwater availability for planning a sustainable future. The USGS is maximizing the impact of these studies by preserving and increasing access to this pertinent information. Providing these data allows the scientific and water management community to more easily access and use the compiled existing and newly derived geologic and hydrologic data to address water related issues/concerns by partners, stakeholders, and the public.
