Water Resources
Announcing the National Water Dashboard!
Our new interactive, mobile-friendly tool provides real-time water, weather, and flood information all in one place
Explore the NWDData and Tools
The USGS Water Resources Mission Area provides water information that is fundamental to national and local economic well-being, protection of life and property, and effective management of the Nation’s water resources. Below, find data and tools relevant to a wide range of water resources and conditions including streamflow, groundwater, water quality, and water use and availability.

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 tem
Surface Geophysical data collected along Blacktail Creek in June 2017 near Williston, North Dakota, USA
The extraction of unconventional oil and gas (UOG) resources often produces highly saline waste waters, which can be released to the river corridor environment during spills and pipe leakage. In North Dakota, USA more than 8,000 spills were recorded from 2008-2015, and more than half of those spills were related to pipelines. Data collected for this study were related to UOG wastewat
Electrical resistivity tomography (ERT) data collected adjacent to Blacktail Creek in June 2017 near Williston, North Dakota, USA
In June 2017, U.S. Geological Survey (USGS) collected geophysical measurements to help map variations in electrical properties to infer shallow flowpaths and storage zones influenced by residual spilled unconventional oil and gas (UOG). Two survey profiles were collected, each including dipole-dipole and Wenner-Schlumberger configurations. For each survey a total of 56 electrodes spac
Electromagnetic Imaging (EMI) data collected along Blacktail Creek in June 2017 near Williston, North Dakota, USA
The electrical conductivity of the earth is used to help infer lithological and pore fluid properties. Various geophysical methods can provide estimates of the distribution of below ground electrical conductivity, with each method having certain limitations. This data release presents raw and processed results from hand-caried frequency domain electromagnetic induction imaging (EMI) data co...
Toxicity Assay Data for Groundwater Contaminated by Petroleum Hydrocarbons near Bemidji, MN (2018)
Groundwater samples were collected in June 2018 from a background (reference) well located 200 m upgradient from the source and five wells along a flowline in the plume at 39, 68, 102, 125, and 254 m downgradient from the source. Before sampling, at least three times the water volume in the well casing was purged and field parameters (temperature, dissolved oxygen, specific co
Dissolved organic carbon, total petroleum hydrocarbons and and toxicity assay results for Bemidji, MN (2018)
In crude-oil-contaminant plumes the dissolved organic carbon (DOC) is mainly hydrocarbon degradation intermediates only partly quantified by the diesel range total petroleum hydrocarbon (TPHd) method. To understand potential biological effects of degradation intermediates we tested three fractions of DOC: (1) solid phase extract (HLB); (2) dichloromethane (DCM-total) e
Nonvolatile dissolved organic carbon (NVDOC), total petroleum hydrocarbons at the USGS crude oil study site near Bemidji, Minnesota, USA (2018)
This data set describes dissolved concentrations in groundwater of nonvolatile dissolved organic carbon (NVDOC), total petroleum hydrocarbons (TPH) in the gasoline (C6-C10), diesel range (C10-C28) with and without silica gel cleanup, and oil range (>C28-C40) with and without silica gel cleanup. Groundwater samples were collected in June 2018 from the USGS crude oil st
Arsenic Speciation method performance data, species hold times data and supporting information
This dataset includes data collected to validate a method of analysis for arsenic species As(III), As(V), dimethylarsinate (DMA), and monomethylarsonate (MMA) in surface water and groundwater samples. It also includes site information and water chemistry for samples used in the validation and used for other studies of arsenic species in groundwater. It includes speciation d
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.
Mercury speciation and other constituent data for surface water and bed sediment associated with the Hamilton Airfield Wetland Restoration, Novato, California. USA
The Hamilton Wetland Restoration Project (HWRP) is a joint venture between the US Army Corps of Engineers (USACE; San Francisco District) and the California State Coastal Conservancy. The site is located on the property of the former Hamilton Army Airfield in Novato, California, along the western edge of San Pablo Bay, which is part of northern San Francisco Bay. The initial stage
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
