Water information is fundamental to national and local economic well-being, protection of life and property, and effective management of the Nation’s water resources. The USGS works with partners to monitor, assess, conduct targeted research, and deliver information on a wide range of water resources and conditions including streamflow, groundwater, water quality, and wateruse and availability.
USGS Water Data for the Nation
The USGS National Water Information System (NWIS) contains surface-water, groundwater, water-quality, and water-use data collected at approximately 1.5 million sites across all 50 states.

Effects of ferric sulfate and polyaluminum chloride coagulation enhanced treatment wetlands on Typha growth, soil and water chemistry
Land surface subsidence is a concern in many deltas worldwide as it contributes to water quality degradation, loss of fertile land and increased potential for levee failure. As a possible solution to these concerns, on-site coagulation enhanced treatment wetlands(CETWs), coagulation water treatment followed by wetland...

Land subsidence along the California Aqueduct in west-central San Joaquin Valley, California, 2003–10
Extensive groundwater withdrawal from the unconsolidated deposits in the San Joaquin Valley caused widespread aquifer-system compaction and resultant land subsidence from 1926 to 1970—locally exceeding 8.5 meters. The importation of surface water beginning in the early 1950s through the Delta-Mendota Canal and in the early 1970s through the...

Assessment of the immune status of wild and laboratory-maintained smallmouth bass
Deaths of young-of-year smallmouth bass in the Chesapeake Bay drainage has been noted since 2005. Studies of affected fish have found bacterial, viral and parasitic infections. Mixed infections suggest these fish are immunosuppressed. Understanding the role of specific pathogens and environmental factors that contribute to their presence is important but equally important is the understanding...
Trace Metals in San Francisco Bay Clams
The clams Potamocorbula amurensis and Corbicula fluminea were collected at a variety of sites in the San Francisco Bay/ Delta beginning July 1990 and ending February 2010. These invasive species were used as biosentinels of the fate, transport, and effects of trace metals in the San Francisco Bay ecosystem.
Linking Selenium Sources to Ecosystems: Mining
Environmental sources of selenium (Se) such as from organic-enriched sedimentary deposits are geologic in nature and thus can occur on regional scales. A constructed map of the global distribution of Se source rocks informs potential areas of reconnaissance for modeling of Se risk including the phosphate deposits of southeastern Idaho and the coals of Appalachia.
Linking Selenium Sources to Ecosystems: Refining
The San Francisco Bay-Delta receives selenium (Se) internally from oil refineries and externally through riverine agricultural discharges. Predator species considered at risk from Se consume the estuary’s dominant bivalve, C. amurensis, an efficient bioaccumulator of Se. Modeling predicts site-specific ecological risk and derives a range of protective Se concentrations for use by decision-...
Linking Selenium Sources to Ecosystems: Irrigation
Adverse effects of selenium (Se) on fish and waterfowl in wetlands receiving agricultural drainage occurred in the 1980s in the San Joaquin Valley of California. The identified mechanisms of Se enrichment helped resolve Se toxicity problems associated with irrigated agriculture in the arid West. Bioaccumulation of Se in ancient marine sediments is postulated as a primary pathway in source...
Linking Selenium Sources to Ecosystems: Modeling
Selenium (Se) as a contaminant of ecosystems is bioaccumulative and causes reproductive effects in fish and wildlife. Ecosystem-scale Se modeling predicts Se bioaccumulation based on dietary biodynamics within site-specific food webs. The model can be used to forecast Se toxicity under different management or regulatory proposals or to translate a tissue guideline to a dissolved guideline. ...
Linking Selenium Sources to Ecosystems: Local and Global Perspectives
The sources, biogeochemistry, and ecotoxicology of selenium (Se) combine to produce a widespread potential for ecological risk such as deformities in birds and fish. Linking the understanding of source characteristics to a mechanistic, biodynamic dietary model of Se exposure on an ecosystem-scale improves the prediction of Se effects and its potential remediation.
The Story of the USGS Research Vessel (R/V) Polaris
For the past 50 years, the USGS has been conducting research in the San Francisco Bay and Delta, California and beyond. This research would not have been possible without the Research Vessel (R/V) Polaris. Many scientists who have been fortunate to work on the Polaris have come and gone, but the Polaris sailed from the South San Francisco Bay continuously from 1968...
Quality Systems Branch (QSB)
The USGS Quality Systems Branch (QSB) represents the Water Mission Area’s commitment to generating environmental data of known quality. QSB produces water and sediment performance-assessment samples and data to provide the USGS laboratory users, USGS laboratories, and field personnel with quantitative performance information to assess data quality.
USGS / National Park Service Water-Quality Partnership
Since 1998, the USGS-National Park Service Water-Quality Partnership has supported 217 projects to protect and improve water quality in 119 national parks. These USGS-NPS collaborative projects support science-based resource management by the National Park Service to address critical water-quality issues for many of our Nation's most highly valued aquatic systems.
The USGS collects, analyzes, and distributes data on a wide variety of water-related issues and resources. Much of our data is publicly available through the National Water Information System (NWIS), but additional datasets and analytical tools are also available.

Watershed Regressions for Pesticides (WARP)
The National Water-Quality Assessment (NAWQA) project developed a series of statistical models, based on monitoring data and watershed characteristics, to enable estimation of pesticide concentrations for streams that have not been monitored.
Water Budgets Across the United States
In this data visualization, you can see how three major components of the water budget vary across the conterminous US. Precipitation is incoming rain and snow; evapotranspiration is outgoing evaporation from soil and water bodies and transpiration through plants; and runoff is excess water that makes its way to lakes and rivers through streams and spring discharges.
Estimated Annual Agricultural Pesticide Use
For all States except California, proprietary farm survey pesticide-use data are aggregated and reported at the multi-county Crop Reporting District (CRD) level. Harvested-crop acreage data by county from the U.S. Department of Agriculture Census of Agriculture are used to calculate the median pesticide-by- crop use rates for each crop in each CRD.
