Data 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.

Groundwater discharge area for Diamond Valley, Central Nevada, 1968

This dataset represents "phreatophyte areas" mapped as part of an analysis of irrigation pumping
in Diamond Valley, Nevada published in 1968. The data were digitized for comparison with mapping
of groundwater discharge areas done in 2011 as part of a groundwater study in these valleys published
in 2016.

MODFLOW2000 and MODFLOW-ASP models used to simulate the groundwater flow in the Atlantic Coastal Plain, North and South Carolina and parts of Georgia and Virginia, Predevelopment to 2004

A three-dimensional groundwater flow model (MODFLOW2000) of the Atlantic Coastal Plain aquifers
and confining units was developed to evaluate groundwater availability and to forecast the potential
effects of climate change on groundwater levels in the study area. Two existing groundwater flow
models that simulated flow and water use in the Coastal Plain aquifers of North...

Data Quality Assurance - Field Replicates

This dataset contains replicate samples collected in the field by community technicians. No field replicates were collected in 2012. Replicate constituents with differences less than 10 percent are considered acceptable.

Mean annual water-budget components for Hawaii Island, Hawaii, for recent conditions, 1916-83 rainfall and 2008 land cover

The shapefile associated with this metadata file represents the spatial distribution of mean annual
water-budget components, in inches, for Hawaii Island, Hawaii. The water-budget components in
the shapefile were computed by a water-budget model for a scenario representative of recent
conditions (1916-83 rainfall and 2008 land cover), as described in USGS Scientific Investiga...

Floodplain sedimentation, bank erosion, and biogeochemical cycling of sediment and nutrients in Smith Creek (Virginia) 2012-2015

Chemical and physical attributes, rates of deposition, erosion, and mineralization of bank and floodplain sediments and soils from five study sites in the Smith Creek watershed between 2012 and 2015.

Adult Aquatic Insects that Emerged from Mesocosms Exposed to Bifenthrin

Direct and indirect ecological effects of the widely used insecticide bifenthrin on stream ecosystems are largely unknown. To investigate such effects, a manipulative experiment was conducted in stream mesocosms that were colonized by aquatic insect communities and exposed to bifenthrin-contaminated sediment; implications for natural streams were interpreted through comparison of mesocosm res...

MODFLOW-USG model of groundwater flow in the Wood River Valley aquifer system in Blaine County, Idaho

A three-dimensional numerical groundwater flow model (MODFLOW-USG) was developed for the
Wood River Valley (WRV) aquifer system, south-central Idaho, to evaluate groundwater and
surface-water availability at the regional scale. The U.S. Geological Survey (USGS), in
cooperation Idaho Department of Water Resources, used the transient groundwater flow
model to simulat

Data Quality Assurance - Laboratory duplicates

This dataset includes data quality assurance information concerning the Relative Percent Difference (RPD) of laboratory duplicates. No laboratory duplicate information exists for 2010. The formula for calculating relative percent difference is: ABS(2*[(A-B)/(A+B)]). An RPD of less the 10% is considered acceptable.

Groundwater discharge areas for Antelope, Kobeh, and Monitor Valleys, Central Nevada, 1964

This dataset represents "phreatophyte areas" mapped as part of a groundwater reconnaissance
effort in four valleys in central Nevada and published in 1964. The data were digitized for comparison
with mapping of groundwater discharge areas done in 2011 as part of a groundwater study in these
valleys published in 2016.

Lower Rio Puerco 1996 georeferenced NAPP photo segments

1996 georeferenced aerial photographs cover the lower Rio Puerco from the confluence with the Rio San Jose 70 km down-valley to the confluence with the Rio Grande. The images were obtained from enlargements of 1:40,000 scale National Aerial Photography Program (NAPP) photographs printed from negatives at a scale of 1:5,000, then scanned at 600 dpi. Pixel size of the raster images is

Lower Rio Puerco 1950s georeferenced aerial photographs

The 1950s images were downloaded from Earth Explorer as medium-resolution scans of aerial photographs, with pixel size ranging from 1.33 to 2.32 m. Original photo scales were 1:54,000 or 1:20,000. (See Source Citation below.) I registered and rectified these images using identifiable common points from 1996 DOQQs. Images with filenames beginning "r37" were acquired 11-29-1953. I

HEC-HMS and HEC-RAS models used to analyze dam failure for the Lago El Guineo Dam, Orocovis, Puerto Rico

The Hydrologic Engineering Center’s Hydrologic Modeling System (HEC-HMS) and Hydrologic Engineering
Center’s River Analysis System (HEC-RAS) computer programs, developed by the U.S. Army Corps of
Engineers, were used for the hydrologic and hydraulic modeling, respectively, to analyze the potential for
dam failure under different hydrologic conditions. The
