This dataset contains 10-foot contours of the 2013 Wenonah-Mount Laurel aquifer potentiometric surface in the Coastal Plain of New Jersey. The potentiometric-surface contours show altitudes at which water levels would have risen in tightly-cased wells and represent conditions in October 2013 through January 2014. Groundwater-level data from 158 wells cased in, and with the screened interval open to the Wenonah-Mount Laurel aquifer, were used to construct the potentiometric surface and are publicly available from the U.S. Geological Survey's National Water Information System.
This dataset contains surface-water-altitude (SWA) data from streamgages that were used or considered (indicated by the field USE_2020) to create a potentiometric-surface map for the Mississippi River Valley alluvial aquifer (MRVA) for spring 2020. The SWA data was referenced to the North American Vertical Datum of 1988 (NAVD 88). The streamgages are measured continuously. The streamgage measurement that was used was from early April 2020 and is an estimate of the groundwater altitudes (GWAs) at the gage location. The resultant potentiometric-surface contours and raster represents the generalized central tendency for spring 2020, but it would not be useful for some purposes, such as for calibration of a groundwater-flow...
A hydrogeologic framework of the Ozark Plateaus aquifer system was constructed as the base for a groundwater flow model developed as part of the U.S. Geological Survey Water Availability and Use Science Program to aid in the understanding of groundwater availability in select aquifer systems of the United States. The Ozark Plateaus aquifer system study area (hereinafter referred to as the “Ozark system”) is nearly 70,000 square miles and includes parts of Arkansas, Kansas, Missouri, and Oklahoma. A hydrogeologic framework was constructed to represent the altitudes and thicknesses of nine hydrogeologic units within the Ozark Plateaus aquifer system - . the Western Interior Plains confining system, Springfield Plateau...

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...

Depth-to-water raster for the shallow groundwater system in the Lower Gunnison River Basin, Colorado
This dataset consists of raster-based depth-to-water values (in feet) for the shallow groundwater system in the Lower Gunnison River Basin in Delta, Montrose, Ouray, and Gunnison Counties, Colorado. Depth-to-water values in this dataset were derived from a geostatistical interpolation of point data presented in the dataset waterlevel_data. The U.S. Geological Survey prepared this dataset in cooperation with the Colorado Water Conservation Board.
This dataset consists of altitudes values (in feet) representing the generalized potentiometric surface of the shallow groundwater system in the Lower Gunnison River Basin in Delta, Montrose, Ouray, and Gunnison Counties, Colorado. Potentiometric-surface altitude values were computed as the difference between land surface and depth to water represented by dataset dtw. The U.S. Geological Survey prepared this dataset in cooperation with the Colorado Water Conservation Board.
This dataset contains monthly pumping rates for municipal and industrial (MnI) wells in the City of Las Cruces, New Mexico network within the Rio Grande Transboundary Integrated Hydrologic Model (RGTIHM). In RGTIHM, these wells are considered the Las Cruces, New Mexico (LCNM) group. Monthly pumping rates are presented in units of cubic feet per day for the period from March 1940 through December 2014.

This point vector dataset represents the location and identification attributes of stream gages used for surface-water flow and flow-difference observations for the Rio Grande transboundary integrated hydrologic model and water-availability analysis, New Mexico and Texas, United States, and Northern Chihuahua, Mexico.
This tabular dataset represents the source of monthly flow at 18 surface-water inflow points used as input into the Streamflow-Routing (SFR) Package for MODFLOW-One-Water Hydrologic Flow Model in the Rio Grande Transboundary Integrated Hydrologic Model (RGTIHM). Fourteen of the inflow points represent wastewater treatment plant (WWTP)/water reclamation plant outfalls, two of the inflow points represent electric plant outfalls, and the remaining two inflow points represent gaged Rio Grande below Caballo Reservoir and Bonita Lateral flows near the beginning of the SFR network within the RGTIHM. See the Inflow_ID attribute in the RGTIHM_SFR_Inflow_Pts and Inflw_ID attribute in the RGTIHM_SFR_Segments feature classes...

This data release contains compiled groundwater withdrawal data from 1980 to 2018 for the Hueco Bolson, Mesilla Basin, and the Rio Grande alluvium in El Paso and Hudspeth Counties, Texas. Most groundwater withdrawal volumes were distributed to wells and separated into water-use categories. The data were compiled, distributed, and categorized as part of the U.S. Geological Survey’s involvement in the Transboundary Aquifer Assessment Program. The Transboundary Aquifer Assessment Act was originally signed into Public Law 109-448 by the 109th United States Congress in 2006. This law directed the Secretary of Interior to establish a U.S.-Mexico Transboundary Aquifer Assessment Program (TAAP) to systematically assess...

The U.S. Geological Survey (USGS) in cooperation with the Harris‐Galveston Subsidence District, City of Houston, Fort Bend Subsidence District, and Lone Star Groundwater Conservation District produced this dataset of groundwater‐level altitudes and groundwater‐level altitude changes in the Chicot, Evangeline, and Jasper aquifers in the Houston‐Galveston region, Texas. This dataset documents current‐year (2020) groundwater‐level altitudes for each aquifer, 5‐year (2015‐20) groundwater‐level changes for each aquifer, long‐term (1990‐2020 and 1977‐2020) groundwater‐level changes for the Chicot and Evangeline aquifers, and long‐term (2000‐2020) groundwater‐level change for the Jasper aquifer. The groundwater‐level measurements...
INTRODUCTION • Concerns over the viability of the fractured bedrock aquifer that provides about 1/3 of Rockland County’s water supply prompted a 5-year study by the U.S. Geological Survey (USGS) to (1) define the hydrogeologic framework of the aquifer, (2) assess conditions within it, and (3) identify other potential sources of water for the County. The study was done in cooperation with Rockland County and the New York State Department of Environmental Conservation. • Population growth in Rockland County to nearly 300,000 people has been paralleled by significant hydrologic changes over the past 50 years –water demand and impervious surface area have increased, and sanitary sewers now serve most areas and discharge...

In 2011, the U.S. Geological Survey, in cooperation with the Town of Newfield and the Tompkins County Planning Department, began a study of the stratified-drift aquifers in the West Branch Cayuga Inlet and Fish Kill valleys in the Town of Newfield, Tompkins County, New York. The objective of this study was to characterize the hydrogeology and water quality of the stratified-drift aquifers in the West Branch Cayuga Inlet and Fish Kill valleys and produce a summary report of the findings. This dataset contains locations of moraines and ice margins identified with lidar imagery in West Branch Cayuga Inlet and Fish Kill Valleys, Newfield, Tompkins County, New York.
