This dataset includes the magnetotelluric (MT) sounding data collected in 2005 along an east-west profile north of Wells, 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. Geological...

This dataset is the result of measurements of groundwater levels in the Equus Beds aquifer near Wichita, Kansas, in January 2016. Potentiometric surfaces are interpolated for the shallow and deep parts of the aquifer, and rasters of the potentiometric surfaces are included in this data release. Wells were classified as being screened in the shallow or deep parts of the aquifer based on station name (some wells have a layer identifier in the station name) or, if no indication of aquifer layer was given in the station name, based on the depth of the well; wells with depths less than 80 feet below land surface were classified as shallow and wells with depths of 80 feet or deeper were classified as deep. Contours with...

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 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.

Cumulatively, headwater streams contribute to maintaining hydrologic connectivity and ecosystem integrity at regional scales. Hydrologic connectivity is the water-mediated transport of matter, energy and organisms within or between elements of the hydrologic cycle. Headwater streams compose over two-thirds of total stream length in a typical river drainage and directly connect the upland and riparian landscape to the rest of the stream ecosystem. Altering headwater streams, e.g., by channelization, diversion through pipes, impoundment and burial, modifies fluxes between uplands and downstream river segments and eliminates distinctive habitats. The large-scale ecological effects of altering headwaters are amplified...

This dataset consists of values representing the generalized thickness (in feet) of regolith sediments (alluvium, colluvium, and weathered bedrock) overlying well-consolidated bedrock in the Lower Gunnison River Basin in Delta, Montrose, Ouray, and Gunnison Counties, Colorado. Regolith thickness in this dataset was derived from contours presented in the dataset rglth_contours. The U.S. Geological Survey prepared this dataset in cooperation with the Colorado Water Conservation Board.
The water resources in Tennessee are likely to be stressed in the future by factors such as population increase, urban and suburban development, climate change, and other competing demands. Water-resource managers and policy makers will need accurate water-use data for regional water-supply planning including infrastructure investment, conservation, and cost-recovery strategies. Quantifying public-supply and self-supplied industrial water use and relating the use to effects on -water resources and natural hydrologic systems; is important for the public and policy makers. This dataset includes public-supply water-use and self-supplied industrial water-use information for the State of Tennessee in 2010. Public supply...

The glacial aquifer system of the United States encompasses all or parts of 25 states and is the most widely used supply of drinking water in the Nation (Maupin and Barber, 2005; Maupin and Arnold, 2010). A series of seven raster data sets were derived from a database of water-well drillers' records that was compiled in partial fulfillment of the goals of the U.S. Geological Survey’s Groundwater Availability and Use assessment program (U.S. Geological Survey, 2002). They contain hydrogeologic information for areas of the U.S. that are north of the southern limit of Pleistocene glaciation, including the total thickness of glacial deposits, thickness of coarse-grained sediment within the glacial deposits, specific-capacity...
Groundwater is a vital resource to the Mississippi embayment region of the central United States. Regional and integrated assessments of water availability that link physical flow models and water quality in principal aquifer systems provide context for the long-term availability of these water resources. An innovative approach using machine learning was employed to predict groundwater pH across drinking water aquifers of the Mississippi embayment. The region includes two principal regional aquifer systems; the Mississippi River Valley alluvial (MRVA) aquifer and the Mississippi embayment aquifer system that includes several regional aquifers and confining units. Based on the distribution of groundwater use for...
The alluvial aquifer of the Mississippi embayment lies within a syncline plunging south towards the Gulf of Mexico with the axis of the syncline roughly following the Mississippi River (Cushing and others, 1964, Hart and others, 2008). The trough of the syncline is comprised of alluvial and terrace deposits of Quaternary age (Ackerman, 1996). A potentiometric-surface map of the Mississippi River Valley alluvial aquifer represents the altitude at which water would stand in tightly cased wells completed at any location within the study area (Schrader, 2015). Using the altitude of water levels measured in the study area, the potentiometric-surface map depicts points of equal altitude with contours denoting a given...
