Layer: Elevation of Aquifer Base (ft), 2020 (ID: 2)

Name: Elevation of Aquifer Base (ft), 2020

Display Field: Altitude

Type: Feature Layer

Geometry Type: esriGeometryPolyline

Description: This dataset represents the base of the Cimarron River alluvium and terrace aquifer, which is defined as the boundary contact between the Quaternary-age alluvium and terrace deposits of the Cimarron River and underlying Permian-age bedrock units.The elevation of the aquifer base ranges from less than 900 feet in Logan County to 1650 feet in Woods County. The interpretation of the base of the aquifer is based on analysis of lithologic data obtained from groundwater well completion reports submitted to the OWRB by licensed well drillers. Control points were added along the defined boundary of the aquifer to aid in the interpolation process, resulting in a depth-to-base raster in feet below land surface. The depth-to-base raster was subtracted from a 10-meter Digitial Elevation Model (DEM) raster of the study area's land surface to create the altitude of the base raster. Contours with a 50 foot interval were extracted from the alititude map and manually smoothed and adjusted by OWRB technical staff to better reflect natural conditions and remove "negative" water areas where the elevation of the base was interpolated to be higher than the elevation of the land surface. This dataset was created as a product of the Cimarron River alluvium and terrace hydrologic investigation and is included here for informational purposes only.
