This polygon vector dataset, delineating principal aquifers in New Mexico, is a clipped and refined version of the original principal aquifers of the United States shapefile (U.S. Geological Survey, 2019).

This data set represents the extent of the Rio Grande aquifer system in the states of Colorado, New Mexico, and Texas.

This data set represents the extent of the Rio Grande aquifer system in the states of Colorado, New Mexico, and Texas.

This data set represents the extent of the Roswell Basin aquifer system in New Mexico.

This digital data set consists of aquifer boundaries for the High Plains aquifer in the central United States. The High Plains aquifer extends from south of 32 degrees to almost 44 degrees north latitude and from 96 degrees 30 minutes to 106 degrees west longitude. The outcrop area covers 174,000 square miles and is present in Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. This digital data set was compiled from a digital coverage that was created for publication of paper maps in McGrath and Dugan (1993, Water-level changes in the High Plains aquifer -- predevelopment to 1991: U.S. Geological Survey Water-Resources Investigations Report 93-4088, 53 p.) The data are not intended for use at scales larger than 1:1,000,000.

This digital data set represents the extent of the High Plains aquifer in the central United States. The extent of the High Plains aquifer covers 174,000 square miles in eight states; Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. This data set represents a compilation of information from digital and paper sources and personal communication. This boundary is an update to the boundary published in U.S. Geological Survey Professional Paper 1400-B and Open-File Report 99-267.

The Pecos River Basin alluvial aquifer, hereinafter referred to as the "Pecos aquifer", is located in western Texas and southeastern New Mexico. The aquifer is primarily composed of alluvial sand and gravel deposits mantled by sand and silt. The Pecos aquifer overlies Permian, Triassic, and Cretaceous-age rocks. The saturated thickness of the aquifer ranges from 0 to 1000 feet. The aquifer can provide highly productive wells where transmissivity is high and saturated thickness is adequate (HA730-E). This data release contains the following feature datasets: Georeferenced images: 1. i_12PCSRVR_bot.tif: Scanned figure of altitude contour lines representing the bottom of the Pecos aquifer. The original figure was from the Groundwater Atlas (HA730-E) figure 28. Extent shapefiles: 1. p_12PCSRVR.shp: Polygon shapefile containing the areal extent of the Pecos aquifer (Pecos_AqExtent). The extent file contains no aquifer subunits. Contour line shapefiles: 1. c_12PCSRVR_bot.shp: Contour line dataset containing altitude values, in feet reference to National Geodetic Vertical Datum of 1929 (NGVD29), across the bottom of the Pecos aquifer (HA730-E). These data were used to create the ra_12PCSRVR_bot.tif altitude raster dataset. Altitude raster files: 1. ra_12PCSRVR_top.tif: Altitude raster dataset of the top of the Pecos aquifer. The altitude values are in meters reference to North American Vertical Datum of 1988 (NAVD88). The top of the aquifer is assumed to be land surface (NED, 100-meter) based on available data. 2. ra_12PCSRVR_bot.tif: Altitude raster dataset of the bottom of the Pecos aquifer. The altitude values are in meters reference to NAVD88. Depth raster files: 1. rd_12PCSRVR_top.tif: Depth raster dataset of the top of the Pecos aquifer. The depth values are in meters below land surface (NED, 100-meter). The top of the aquifer is assumed to be at land surface (NED, 100-meter) based on available data. 2. rd_12PCSRVR_bot.tif: Depth raster dataset of the bottom of the Pecos aquifer. The depth values are in meters below land surface (NED, 100-meter).

This is a 100-meter cell resolution raster dataset consisting of 1:750,000-scale surficial geology for California and 1:500,000-scale for Nevada, and parts of Utah, Colorado, New Mexico, and Arizona. This data set was aggregated from a compilation of geologic maps of the Southwest Regional GAP Analysis Project (ReGAP) along with California geology and the very southern portion of Oregon and Idaho geology.
