Data

The USGS Water Resources Mission Area provides water information that is fundamental to our economic well-being, protection of life and property, and effective management of our water resources. Listed below are discrete data releases and datasets produced during our science and research activities. To explore and interact with our data using online tools and products, view our web tools.

Selenium concentrations in food webs of Lake Koocanusa in the vicinity of Libby Dam (MT) and the Elk River (BC) as the basis for applying ecosystem-scale modeling, 2008-2018

This Data Release presents multi-agency data for selenium concentrations in ecosystem media that includes water column, suspended particulate material, zooplankton, invertebrates, and fish. Because the data are compiled from multiple sources, the significant figures used to report contaminant concentrations and other metrics may not be internally consistent. These data will serve as the basis for

Eddy covariance measurements of ET, CO2 and Energy Fluxes, and, ancillary data for the Ft. Logan-Denver urban lawn site

This dataset includes the following measurements made over a managed lawn at Fort Logan Cemetery in Denver Colorado in 2011 and 2012. (No measurements were made in winter months: December, January, February). 1) half hourly eddy covariance measurements of evapotranspiration and fluxes of carbon dioxide and sensible heat 2) half hour averages of solar and net radiation, air temperature and humidity

Eddy covariance measurements of ET, CO2 and Energy Fluxes, and, ancillary data for the Rocky Flats National Wildlife Refuge West site

This dataset includes the following measurements made over a xeric tall grass prairie in the southwest portion of Rocky Flats National Wildlife Refuge in 2011 and 2012: 1) half hourly eddy covariance measurements of latent heat flux (evapotranspiration) and fluxes of carbon dioxide and sensible heat, and friction velocity (U star) 2) half hour averages of solar and net radiation; photosyntheticall

Data used to model and map pH and redox conditions in the Northern Atlantic Coastal Plain aquifer system, eastern USA

Data used to model and map pH and redox conditions in groundwater in the Northern Atlantic Coastal Plain aquifer system, eastern USA, are documented in this data release. The models use as input data measurements of pH and dissolved oxygen concentrations at about 3000 to 5000 wells, which were compiled primarily from U.S. Geological Survey and U.S. Environmental Protection Agency databases. The bo

Data for laboratory experiments conducted with the mayfly Neocloeon triangulifer to derive uranium bioaccumulation parameters and predict site-specific U accumulation, 2016-2019

The U.S. Geological Survey is studying the underlying processes controlling uranium (U) bioaccumulation in aquatic invertebrates by experimentally parameterizing conditional rate constants for aqueous U uptake, dietary U uptake and U elimination. This data release makes available data from laboratory experiments conducted with the aquatic baetid mayfly Neocloeon triangulifer.

Twelve-digit hydrologic unit actual evapotranspiration and snowpack water equivalent storage from the National Hydrologic Model Infrastructure with the Precipitation-Runoff Modeling System 1980-2016

This dataset is part of the National Water Census Water Budget Estimation and Evaluation Project's ongoing development of best estimates of daily historical water budgets for over 100,000 hydrologic units across the United States. In this release, estimates of actual evapotranspiration and snowpack water equivalent storage are added to the already released estimates of soil moisture, recharge, str

Image data and field measurements used to map salmon spawning locations via remote sensing, American River, California, November 5-7, 2018

This data release includes images and field measurements used to map chinook salmon spawning locations along the American River near Sacramento, California, via remote sensing; the data were collected November 5-7, 2018. The purpose of this study was to develop and test a spectrally based technique for identifying salmon spawning locations, known as redds, from various types of remotely sensed da

Tabular data for selected items from the Census of Agriculture for the period 1950-2017 for counties in the conterminous United States

This product provides tabular data from the U.S. Department of Agriculture (USDA) Census of Agriculture for selected items for the period 1950-2017 for counties in the conterminous United States. Data from 1950-2012 are taken from LaMotte (2015) and 2017 data are retrieved from the USDA QuickStats online tool. Data which are withheld in the Census of Agriculture are filled with estimates. The data

Chemistry of water, stream sediment, wildfire ash, soil, dust, and mine waste for Fourmile Creek Watershed, Colorado, 2010-2019

In response to the 2010 Fourmile Canyon fire near Boulder, Colorado, the U.S. Geological Survey collected data to support investigations into the magnitude and critical drivers of water-quality impairment after wildfire. We analyzed chemistry of stream water, sediment, wildfire ash, soil, dust, and mine waste for metals and other parameters in order to evaluate the effects of legacy mining and wil

Benthic Community and Bivalve Metrics Data in the Sacramento - San Joaquin Delta from 2015 to 2018

Declining phytoplankton biomass and the resulting stress on the food web has been suggested as one contributor to the decline of Delta Smelt and other fish species in the San Francisco Bay (SFB) and the Sacramento San Joaquin River Delta. Filter feeding by two species of bivalves, Corbicula fluminea and Potamocorbula amurensis, has been shown to control phytoplankton growth rate in the SFB and Del

Acetylene Consumption and Dechlorination by a Groundwater Microbial Enrichment Culture

This study aimed to (1) enrich microbial acetylenotrophs from trichloroethylene (TCE) contaminated groundwater and (2) evaluate whether these enrichments could degrade TCE coupled to acetylene degradation. Acetylenotrophs are microorganisms that use acetylene as their carbon and energy source. TCE contaminated groundwater was collected from wells at the Naval Air Warfare Center (NAWC) in West Tren
