The Roswell Basin aquifer system is located in southeastern New Mexico. It is composed of an alluvial aquifer and an underlying carbonate-rock aquifer. The aquifer covers an area of about 2,200 square miles and the alluvial aquifer covers about 1,200 square miles of the eastern half of this area. The alluvial aquifer primarily consists of Quaternary sediments and the carbonate-rock aquifer consists of the San Andres Limestone. Both aquifers offer highly productive groundwater wells that are extensively used for agricultural, industrial, and municipal use (HA 730-C). This product provides source data for the Roswell Basin aquifer system framework, including: Georeferenced images: 1. i_43RSWLBS_top.tif: Digitized figure of altitude contour lines representing the top of the Roswell Basin aquifer system. The original figure was from the Geohydrologic Framework of the Roswell Ground-water Basin report (Welder, 1983). Extent shapefiles: 1. p_43RSWLBS.shp: Polygon shapefile containing the areal extent of the Roswell Basin aquifer system. This shapefile was sourced from Roswell_AqExtent and was modified based off of (Welder, 1983). The extent file contains no aquifer subunits. Contour line shapefiles: 1. c_43RSWLBS_top.shp: Contour line dataset containing altitude values, in feet reference to National Geodetic Vertical Datum of 1929 (NGVD29), across the top of the Roswell Basin aquifer system. These data were used to create the ra_43RSWLBS_top.tif raster dataset. Altitude raster files: 1. ra_43RSWLBS_top.tif: Altitude raster dataset of the top of the Roswell Basin aquifer system. The altitude values are in meters reference to North American Vertical Datum of 1988 (NAVD88). This file was interpolated from the contour line dataset (Welder, 1983). 2. ra_43RSWLBS_bot.tif: Altitude raster dataset of the bottom of the Roswell Basin aquifer system. The altitude values are in meters reference to NAVD88. Depth raster files: 1. rd_43RSWLBS_top.tif: Depth raster dataset of the top of the Roswell Basin aquifer system. The depth values are in meters below land surface (NED, 100-meter). 2. rd_43RSWLBS_bot.tif: Depth raster dataset of the bottom of the Roswell Basin aquifer system. The depth values are in meters below land surface (NED, 100-meter).

This is a release of data presented in the report "Binational Study of the Transboundary San Pedro Aquifer", Callegary and others, 2016: Callegary, J.B., Minjárez Sosa, I., Tapia Villaseñor, E.M., dos Santos, P., Monreal Saavedra, R., Grijalva Noriega, F.J., Huth, A.K., Gray, F., Scott, C.A., Megdal, S.B., Oroz Ramos, L.A., Rangel Medina, M., Leenhouts, J.M., 2016, Binational Study of the Transboundary San Pedro Aquifer: International Boundary and Water Commission. The United States and Mexico share waters in a number of hydrological basins and aquifers that cross the International Boundary. Both the United States and Mexico recognize that, in a region of scarce water and expanding populations, better scientific understanding of water quantity and quality in these aquifer systems would benefit decision makers planning and managing water resources on both sides of the border. A focus on the sustainability of the aquifer and the San Pedro River which it supports would benefit both Mexico and the United States. These include the fact that the aquifer is transboundary in nature, the river has an elevated ecological value because of the riparian ecosystem it sustains, and that water resources are needed to permit continued development. Recognizing these goals, an agreement was made to integrate hydrologic and other pertinent data from both countries and to proceed with this joint binational study of the San Pedro River transboundary aquifer.

This data set represents the extent of the Arbuckle-Simpson aquifer in Oklahoma.

This data set represents the extent of the Edwards-Trinity aquifer system in the states of Texas, Oklahoma, and Arkansas.

This tabular dataset contains the location and construction information of select wells in the Albuquerque area, central New Mexico, and groundwater-level measurements at those wells from 2014 to 2018. Wells in this dataset are screened or assumed to be screened in the production zone (generally the interval of the aquifer where production wells are screened) of the Santa Fe Group aquifer system. Groundwater-level elevations from this dataset were used to create groundwater-level contours for winter of water year 2016.
