Henson 2018 online document U.S. Geological Survey Open-File Report 2018–1091 https://doi.org/10.3133/ofr20181091 This line vector dataset represents initial groundwater head contours used as input data for the Rio Grande transboundary integrated hydrologic model and water-availability analysis, New Mexico and Texas, United States, and Northern Chihuahua, Mexico. This dataset was created as part of a U.S. Geological Survey study, done in cooperation with the U.S. Bureau of Reclamation, to be used as input data for the Rio Grande transboundary integrated hydrologic model and water-availability analysis, New Mexico and Texas, United States, and Northern Chihuahua, Mexico. The intended uses of this dataset include, but are not limited to, natural resource modeling, mapping, and visualization applications.

Microsoft Windows 7 Version 6.1 (Build 7601) Service Pack 1; ESRI ArcCatalog 10.3.1.4959 No formal attribute accuracy tests were conducted. Verification was done by interactive on-screen review. Frequency tests were performed on all feature class attributes to check that no features were unlabeled, misspelled, or inconsistent. The logical consistency topologically is clean. Chain-node topology is present. Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details. A formal accuracy assessment of the horizontal positional information in the dataset has not been conducted. A formal accuracy assessment of the vertical positional information in the dataset has not been conducted. A GIS was used to generate a composite set of groundwater head contours by compiling and editing spatial information from Conover (1954) and Wilson and others (1981). 1947 water-table contours for Doña Ana County from Conover (1954, plate 1) and January 1976 water-table contours for the Rincon Valley and adjacent areas from Wilson and others (1981, plate 5) were digitized separately and merged into a single dataset. Contours from these two sources were extended into regions of the Rio Grande Transboundary Integrated Hydrologic Model (RGTIHM) active area not covered by this merged dataset, and were connected where deemed appropriate. 2016 Vector String 94 NAD 1983 UTM Zone 13N 0.9996 -105.0 0.0 1640416.66666667 0.0 coordinate pair 0.0001 0.0001 US foot D North American 1983 GRS 1980 6378137.0 298.257222101 RGTIHM_Initial_Head_Contours Line Feature Class ESRI FID Internal feature number ESRI Sequential unique whole numbers that are automatically generated Shape Feature geometry ESRI Coordinates defining the features WL_ft Elevation of the water table contour, in feet, relative to the National Geodetic Vertical Datum of 1929 (NGVD29).
