Service Description: The updated Ogallala - Roger Mills aquifer boundary was created for the Hydrologic Investigation of the Ogallala - Roger Mills aquifer in West-Central Oklahoma 2020, using geologic maps, satellite images, field observations, and well logs from the OWRB database. The extent of the aquifer as defined in this study is the area underlain by the Ogallala Formation in Roger Mills County. The aquifer extent is primarily based on the Oklahoma Geological Survey (OGS) preliminary geologic map of the Foss Reservoir quadrangle and the Elk City quadrangle geologic map. Discrepancies between the OGS maps were rectified using satellite imagery and field observations, specifically from 35°24ˈ23ˈˈN to 35°30ˈ55ˈˈ and 99°38ˈ27ˈˈW to 100°0ˈ0ˈˈW. The Ogallala Formation continues west into Texas, which is beyond OWRB jurisdiction, and north of the Canadian River, where it is referred to as the Ogallala – Northwest aquifer by the OWRB. This dataset is tentative and pending Board approval for permitting use.

Title: Hydrologic Investigation of the Ogallala - Roger Mills aquifer in West-Central Oklahoma 2020
Author: Jon Sanford
Comments: The updated Ogallala - Roger Mills aquifer boundary was created for the Hydrologic Investigation of the Ogallala - Roger Mills aquifer in West-Central Oklahoma 2020, using geologic maps, satellite images, field observations, and well logs from the OWRB database. The extent of the aquifer as defined in this study is the area underlain by the Ogallala Formation in Roger Mills County. The aquifer extent is primarily based on the Oklahoma Geological Survey (OGS) preliminary geologic map of the Foss Reservoir quadrangle and the Elk City quadrangle geologic map.

Subject: The purpose of this dataset is to show the boundary of the Ogallala - Roger Mills aquifer in west-central Oklahoma.
