Aquifer framework datasets used to represent the Rush Springs aquifer, Oklahoma, New Mexico

The Rush Springs aquifer resides in west-central Oklahoma with an area of about 1,400 square miles. The aquifer consists of the Rush Springs Sandstone and the Marlow Formation which are part of the Whitehorse Group of Permian age (HA 730-E). The Rush Springs Sandstone has a maximum thickness of about 300 feet and the Marlow Formation has a maximum thickness of about 125 feet. The aquifer is primarily and extensively used for irrigation (HA 730-E).  
 
This product provides source data for the Rush Springs aquifer framework, including:
Georeferenced images: 
1. i_26RSHSPG_bot.tif: Scanned figure of altitude contour lines representing the bottom of the Rush Springs aquifer. The original figure was from the Water-Resources Investigations Report 98-4081 (WRIR, 98-4081) figure 6. 
 
Extent shapefiles: 
1. p_26RSHSPG.shp: Polygon shapefile containing the areal extent of the Rush Springs aquifer (Rush_Springs_AqExtent). The extent file contains no aquifer subunits.
 
Contour line shapefiles: 
1. c_26RSHSPG_top.shp: Contour line dataset containing altitude values, in feet reference to National Geodetic Vertical Datum of 1929 (NGVD29), across the top of the Rush Springs aquifer. This dataset was sourced from Rush_Springs_AqExtent and was used to create ra_26RSHSPG_top.tif raster dataset.
2. c_26RSHSPG_bot.shp: Contour line dataset containing altitude values, in feet reference to NGVD29, across the bottom of the Rush Springs aquifer. This dataset was sourced from WRIR, 98-4081 and was used to create ra_26RSHSPG_bot.tif raster dataset.
 
Altitude raster files: 
1. ra_26RSHSPG_top.tif: Altitude raster dataset of the top of the Rush Springs aquifer. The altitude values are in meters reference to North American Vertical Datum of 1988 (NAVD88). This raster was interpolated from the c_26RSHSPG_top.shp dataset.
2. ra_26RSHSPG_bot.tif: Altitude raster dataset of the bottom of the Rush Springs aquifer. The altitude values are in meters reference to NAVD88. This raster was interpolated from the c_26RSHSPG_bot.shp dataset.
 
Depth raster files: 
1. rd_26RSHSPG_top.tif: Depth raster dataset of the top of the Rush Springs aquifer. The depth values are in meters below land surface (NED, 100-meter).
2. rd_26RSHSPG_bot.tif: Depth raster dataset of the bottom of the Rush Springs aquifer. The depth values are in meters below land surface (NED, 100-meter).
