Description: The updated Rush Springs study area was created for the Hydrologic Investigation of the Rush Springs Aquifer in West-Central Oklahoma, using geologic maps and well logs from the OWRB database. The southern and eastern portions of the aquifer extent is drawn along the edge of the Rush Springs sandstone and Marlow formation based on geologic maps from the Oklahoma Geological Survey. The Rush Springs sandstone and Marlow formation are present to the north of the North Canadian River; however, the North Canadian River was used as the aquifer extent. The western extent was set based on well log information. This dataset is tentative and pending Board approval for permitting use.

Name: Elevation of Aquifer Base (ft) (Rush Springs)
Display Field: Id
Type: Feature Layer
Geometry Type: esriGeometryPolyline
Description: This dataset represents the base of the Rush Springs aquifer, which is defined as the base of the Marlow Formation by the OWRB for their study released in 2018. The elevation of the aquifer base ranges from 900-1850 feet above mean sea level, with an average of 1414 feet above mean sea level. 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 with zero depth were added along the base of the Marlow Formation as shown on surficial geologic maps published by the Oklahoma Geologic Survey (OGS). The combined depth information was subtracted from a 10-meter Digital Elevation Model (DEM) of the study area’s land surface. The resulting elevation dataset was used with the IDW tool in ArcMap to interpolate the base of the aquifer across the study area. The raster was then converted to a series of contours, using the contour tool in ArcMap, which were then smoothed and manually adjusted by OWRB staff for clarity based on professional judgement. This dataset was created as a product of the Rush Springs hydrologic investigation and is included here for informational purposes only.

Name: Elevation of Potentiometric Surface (ft) (Rush Springs)
Display Field: Id
Type: Feature Layer
Geometry Type: esriGeometryPolyline
Description: The potentiometric surface map of the Rush Springs aquifer was first created by using groundwater levels collected by OWRB staff in March 2013, and refined later by using groundwater levels collected by the USGS in February-April 2013 for the Canadian River Alluvium and Terrace project which included wells in the Rush Springs, and with water level data collected by OWRB staff during 2014 slug tests in the Rush Springs to assist in areas with limited data. Historic data were also used to help with portions of the aquifer with little to no water level data. Additionally, a digital elevation model of the land surface was used to refine contours around major breaks in slope along the Canadian and Washita Rivers. The original raster was created using Inverse Distance Weighted interpolation. This dataset was created as a product of the Rush Springs hydrologic investigation and is included here for informational purposes only.

Name: Altitude (ft) of the Base of the Cloud Chief Formation (Rush Springs)
Display Field:
Type: Raster Layer
Geometry Type: null
Description: The base of the Cloud Chief formation was interpreted by OWRB Staff for their study of the Rush Springs aquifer released in 2018. This study revealed that the potentiometric surface extended above the Rush Springs Formation and into the overlying Cloud Chief Formation. The elevation of the base of the Cloud Chief ranges from 1350-2045 feet above mean sea level (MSL) with a mean elevation of 1700 feet above MSL. Depths to the base of the Cloud Chief formation were obtained from groundwater well completion reports across the study area and submitted to the OWRB by licensed well drillers. Control points with zero depth were added along the base of the formation as shown on surficial geologic maps published by the Oklahoma Geologic Survey (OGS). These depths were converted to elevations by subtracting them from the surface digital elevation model (DEM) raster using the 'minus' tool. Negative values were made to equal zero using the 'reclassify' tool. The resulting elevation dataset was used to interpolate the base of the formation using the inverse distance weighted (IDW) tool in ArcMap. The raster cell size is 152.4 square meters.

Description: Saturated thickness map of the Rush Springs aquifer in central Oklahoma. Map displays the thickness of the water level (potentiometric) surface in the Rush Springs aquifer to the base of the unit, which is defined as the base of the Marlow Formation by the OWRB for their study released in 2018. Saturated thickness ranges between 0-432 feet, with an average saturated thickness of 181 feet. In areas where the potentiometric surface rises above the top of the Rush Springs Formation into the Cloud Chief Formation, the thickness was capped at the Rush Springs/Cloud Chief contact. This calculation was done in ArcGIS 10.2.2 using a raster calculator subtracting the saturated thickness within the Cloud Chief from the total saturated thickness. Also used in the process was the Mosaic to New Raster tool to create a raster that included values from both the smaller extent Cloud Chief and the larger extent Rush Springs in one output raster with the extent of the entire Rush Springs aquifer.
