Water levels in 93 wells completed in the Wood River Valley aquifer system were measured during October 22–24, 2012; these wells are part of a network established by the U.S. Geological Survey in 2006. Maps of the October 2012 water-table altitude in the unconfined aquifer and the potentiometric -surface altitude of the confined aquifer have similar topology to those on maps of October 2006 conditions. Between October 2006 and October...

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This data set describes ground-water regions in the United States defined by the U.S. Geological Survey. These ground-water regions are useful for dividing the United States into areas of roughly similar hydrologic characterstics and water-use patterns. Most of these regions are very generalized and were developed from a illustration published at a scale of approximately 1:20 million. The data set also includes polygon features for...

This dataset documents the depth to groundwater measured in wells screened in the Chicot, Evangeline, and Jasper aquifers in the Houston‐Galveston region, Texas for 2019. The U.S. Geological Survey prepared this dataset in cooperation with the Harris‐Galveston Subsidence District, City of Houston, Fort Bend Subsidence District, Lone Star Groundwater Conservation District, and Brazoria County Groundwater Conservation District. This dataset was created to provide resource managers, public officials, researchers, and the general public with ready access to information regarding depths to groundwater in the region. All of the data in this dataset were collected from December 2018 through March 2019 and are stored in...
The Nacatoch Sand in southwestern Arkansas, hereafter referred to as the Nacatoch aquifer, is a source of groundwater for agricultural, domestic, industrial, and public use inClark, Hempstead, Little River, Miller and Nevada counties. Water-level altitudes measured in 39 wells completed in the Nacatoch aquifer were used to create a potentiometric-surface map. Groundwater flow direction is towards the south and southeast in Hempstead, Little River, and Nevada Counties in southwestern Arkansas. A possible cone of depression may exist in southern Clark County and likely alters groundwater flow from a regional direction toward the depression. This shapefile depicts the generalized extent of the Southwest Nacatoch aquifer.

Groundwater withdrawals are published by county and use type every 5 years by the U.S. Geological Survey (http://water.usgs.gov/watuse/) and published values often do not specify the aquifer(s) from which the withdrawals are derived. The items included in this dataset represent estimates of water use by aquifer in the southeastern United States in order to provide better insight into the 3-dimensional distribution of groundwater withdrawals in time and space.

Transient electromagnetic (TEM) soundings were made in the San Luis Valley, Colorado, to map the location of a blue clay unit as well as to investigate the presence of suspected faults. A total of 147 soundings were made near and in Great Sand Dunes National Park and Preserve, and an additional 6 soundings were made near Hansen Bluff on the eastern edge of the Alamosa National Wildlife Refuge. The blue clay is a significant hydrologic feature in the area that separates an unconfined surface aquifer from a deeper confined aquifer. Knowledge of its location is important to regional hydrological models. Previous analysis of well logs has shown that the blue clay has a resistivity of 10 ohm-meters or less, which is...
This dataset includes the magnetotelluric (MT) sounding data collected in 2008 in and near the Patagonia Mountains of Arizona. The U.S. Geological Survey (USGS) conducted a series of multidisciplinary studies as part of the Assessment Techniques for Concealed Mineral Resources project funded by the USGS Minerals Resources Program in cooperation with the U.S. Forest Service.
This dataset contains monthly pumping rates for municipal and industrial (MnI) wells in New Mexico within the Rio Grande Transboundary Integrated Hydrologic Model (RGTIHM) that were not included in other pumping rate datasets. In RGTIHM, these wells are considered the New Mexico Office of the State Engineer MnI (NMOSE_MnI) group. Monthly pumping rates are presented in units of cubic feet per day for the period from March 1940 through December 2014.

This dataset includes the magnetotelluric (MT) sounding data collected in 2003 along a north-south profile west of Wendover, Nevada. It is important to know whether major mining districts in the Northern Nevada Gold Province are underlain by rocks of the Archean Wyoming craton, which are known to contain orogenic gold deposits, or by accreted rocks of the Paleoproterozoic Mojave province. It is also important to know the location and orientation of the Archean/Proterozoic suture zone between these provinces as well as major basement structures within these terranes because they may influence subsequent patterns of sedimentation, deformation, magmatism, and hydrothermal activity. This study was funded by the U.S....
Groundwater is a vital resource in the Mississippi embayment of the central United States. An innovative approach using machine learning (ML) was employed to predict groundwater salinity—including specific conductance (SC), total dissolved solids (TDS), and chloride (Cl) concentrations—across three drinking-water aquifers of the Mississippi embayment. A ML approach was used because it accommodates a large and diverse set of explanatory variables, does not assume monotonic relations between predictors and response data, and results can be extrapolated to areas of the aquifer not sampled. These aspects of ML allowed potential drivers and sources of high salinity water that have been hypothesized in other studies to...
This dataset represents an estimated representation of net annual recharge of surficial aquifers in Wyoming from natural sources. Irrigation or other man-made recharge structures are not represented. Estimated recharge is calculated using a simplistic formula based on soil type and average annual rainfall. The dataset is in raster format with 500 meter cell size. For more details about this dataset, please refer to this report: Hamerlinck, J.D. and Arneson, C.S., editors, 1998, Wyoming Ground-Water Vulnerability Assessment Handbook: Volume 1. Background, Model Development, and Aquifer Sensitivity Analysis: Wyoming Geographic Information Science Center Publication WyGISC 98-01-1, University of Wyoming, Laramie, WY.

This data represents a depiction of the Depth to Initial Ground Water for the state of Wyoming (excluding Yellowstone National Park) at a 100 meter cell resolution, 1:100,000 scale. The data was created by using Kriging to interpolate a smooth surface between known data points obtained from the Wyoming State Engineer's Office well permit records at various years.
