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.
The USGS next-generation water observing system will provide high-fidelity, real-time data on water quantity and quality necessary to support modern water prediction and decision support systems for water emergencies and daily water operations. The Delaware River Basin pilot provides an opportunity to develop the NextGen observing system in a nationally important, complex interstate river...
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.

Lake sediment fecal and biomass burning biomarkers provide direct evidence for prehistoric human-lit fires in New Zealand
Deforestation associated with the initial settlement of New Zealand is a dramatic example of how humans can alter landscapes through fire. However, evidence linking early human presence and land-cover change is inferential in most continental sites. We employed a multi-proxy approach to reconstruct anthropogenic land use in New Zealand’s South...Argiriadis, Elena; Battistel, Dario; McWethy, David B.; Vecchiato, Marco; Kirchgeorg, Torben; Kehrwald, Natalie; Whitlock, Cathy; Wilmshurst, Janet M.; Barbante, Carlo
Geologic framework and hydrogeology of the Rio Rico and Nogales 7.5’ quadrangles, upper Santa Cruz Basin, Arizona, with three-dimensional hydrogeologic model
Rapid population growth and declining annual recharge to aquifers in the upper Santa Cruz Basin area of southern Arizona, have increased the demand for additional groundwater resources. This demand is predicted to escalate in the future because of higher temperatures, longer droughts, less aquifer recharge, and decreased river and stream base flow...Page, William R.; Bultman, Mark W.; VanSistine, D. Paco; Menges, Christopher M.; Gray, Floyd; Pantea, Michael P.
Pliocene erosional pulse and glacier-landscape feedbacks in the western Alaska Range
Pliocene–Pleistocene glaciation modified the topography and erosion of most middle- and high-latitude mountain belts, because the evolution of catchment topography controls long-term glacier mass balance and erosion. Hence, characterizing how erosion rates change during repeated glaciations can help test hypothesized glacier erosion-landscape...Lease, Richard O.
Lake levels in a discontinuous permafrost landscape: Late Holocene variations inferred from sediment oxygen isotopes, Yukon Flats, Alaska
During recent decades, lake levels in the Yukon Flats region of interior Alaska have fluctuated dramatically. However, prior to recorded observations, no data are available to indicate if similar or more extreme variations occurred during past centuries and millennia. This study explores the history of Yukon Flats lake origins and lake levels for...Anderson, Lesleigh; Finney, Bruce P.; Shapley, Mark D.
Improving understanding of soil organic matter dynamics by triangulating theories, measurements, and models
