Data and Tools

Science Datasets

The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Groundwater altitude data, from monitoring-networks wells, considered for the potentiometric surface map, Mississippi River Valley alluvial aquifer, spring 2016

A potentiometric surface map for spring 2016 was created for the Mississippi River Valley alluvial (MRVA) aquifer, which was referenced to the North American Vertical Datum of 1988 (NAVD 88), using most of the available groundwater-altitude data from wells and surface-water-altitude data from streamgages. Most of the wells were measured annually or one time, after installation, but some wells...

Datasets for Integrating stream gage data and Landsat imagery to complete time-series of surface water extents in Central Valley, California

This data release comprises the data files and code necessary to perform all analyses presented in the associated publication. The *.csv data files are aggregations of water extent on the basis of the European Commission's Joint Research Centre (JRC) Monthly Water History database (v1.0) and the Dynamic Surface Water Extent (DSWE) algorithm. The shapefile dataset contains the study area 8-...

Data and Shapefiles for the Potentiometric Surface of the South Coast Aquifer and Hydrologic Conditions in the Santa Isabel area, Puerto Rico, March-April 2014

A groundwater level survey and reconnaissance of the hydrologic conditions in the South Coast aquifer in the Santa Isabel area of southern Puerto Rico was conducted during March 31 to April 17, 2014. The field survey included groundwater level measurements at 55 wells and instantaneous streamflow measurements at 15 locations in streams and irrigation canals. A potentiometric surface map of the...

Monitoring data to support the operation of the Electric Dispersal Barrier System on the Chicago Sanitary and Ship Canal at Romeoville, Illinois, October 1, 2017, to September 30, 2018.

The U.S. Geological Survey monitors water surface flow reversals, commercial vessel traffic, and temperature and specific conductance in the U.S. Army Corps of Engineers Electric Dispersal Barrier System (EDBS) on the Chicago Sanitary and Ship Canal, Chicago, Illinois. This data release is the 2018 water year summary of the EDBS monitoring data. Water surface flow reversals at the EDBS are...

U-series and Sr-isotope data release supporting Tufa and Water Radiogenic Geochemistry and Tufa Ages for Two Karst Aquifers in the Buffalo National River Region, Northern Arkansas

This dataset includes tables of U- and Th-isotopic data used to calculate uranium-series age estimates (230Th/U method) and initial 234U/238U activity ratios for samples of tufa mounds formed by groundwater seepage. In addition, data include 87Sr/86Sr and 234U/238U values determined for spring discharge and streamflow collected from sites in the vicinity of Buffalo National River.

Controlled source audio-frequency magnetotellurics (CSAMT) data from the Grand Canyon West and Plain Tank Flat areas of the western Hualapai Reservation, Arizona

Controlled source audio-frequency magnetotellurics (CSAMT) data were collected in the Grand Canyon West and Plain Tank Flat areas of the western Hualapai Reservation, Arizona, to better understand the hydrogeology of the area. CSAMT data provide vertical cross-section (profile) data about the resistivity of the subsurface, which may be related to lithologic boundaries and (or) grain-size...

Public Supply Water Use in the Cumberland River Watershed in 2010 and Projections of Public-supply Water Use to 2040

Adequate water resources are vital for municipal needs in the Cumberland River watershed. As a result of continuing population growth, moderate to extreme droughts and floods, demands for competing water resources, and aging infrastructure, the evaluation of ongoing water-resources issues has become increasingly important to Federal, State, and local water-resources managers. In order to...

Monthly summaries of pixel counts in Dynamic Surface Water Extent (DSWE) classes in level-8 HUCs in the greater Central Valley, California

The dataset comprises a Landsat-derived assessment of monthly surface water extent within the study area (California's greater Central Valley). The surface water dataset is based on the algorithm for the Dynamic Surface Water Extent (DSWE) (Jones, 2019), which was adapted to the Google Earth Engine JavaScript environment. The level of spatial aggregation is by level-8 hydrologic unit code (...
