Russell 20200301 publication U.S. Geological Survey Scientific Investigations Map 2020-XXXX Reston, Virginia U.S. Geological Survey https://doi.org/10.3133/sir2020#### The Ozark Plateau aquifer system stretches across approximately 70,000 square miles (mi2) of Arkansas, Missouri, Kansas and Oklahoma, and is composed of many hydrogeologic units, such as the Boone aquifer and the Roubidoux aquifer. However, this data release is focused on only 11,000 mi2 in northern Arkansas, southeastern Kansas, southwestern Missouri, and northeastern Oklahoma. The Boone aquifer covers approximately 10,700 mi2 of this area, and the Roubidoux aquifer covers the 11,000 mi2 area entirely. These aquifers are mostly made of Mississippian-aged and Ordovician-aged carbonate rock, and serve as the main sources of fresh groundwater in northeastern Oklahoma (Imes and Emmett, 1994). In 2017, the U.S. Geological Survey (USGS) and Oklahoma Water Resources Board (OWRB) began a hydrologic investigation to support a determination of maximum annual yields for the Boone and Roubidoux aquifers. This data release provides components of the hydrogeologic framework for that hydrologic investigation. To further characterize the hydrogeologic framework of the aquifers, contours and digital elevation models (DEMs) were created and modified on the following hydrogeologic units (listed from youngest to oldest): the Western Interior Plains confining unit, the Boone aquifer, the Ozark confining unit, and the Roubidoux aquifer. These contours and DEMs represent the altitudes of the bases of each hydrogeologic unit in feet. The hydrogeologic-unit names in this data release are consistent with those used in Oklahoma (Osborn, 2001; Czarnecki and others, 2009) and may differ from those used in regional reports describing the Ozark Plateaus aquifer system (Imes and Emmett, 1994; Westerman and others, 2016). The purpose of this data release is to provide components of the hydrogeologic framework for an ongoing (2019) hydrologic investigation focused on the Boone and Roubidoux aquifers in northeastern Oklahoma. This hydrologic investigation can aid the OWRB in determining the maximum annual yields for both aquifers. 20190501 ground condition Complete None planned -95.4871 -93.6297 37.4475 34.8245 ISO 19115 Topic Category inlandWaters elevation geoscientificInformation USGS Thesaurus contouring geospatial datasets digital elevation models structural geology hydrogeology stratigraphic sections None altitude aquifer Oklahoma hydrogeologic framework Boone Roubidoux Ozark Plateaus aquifer system Ozark Water Science Center U.S. Geological Survey USGS Metadata Identifier USGS:5d701910e4b0c4f70cfa8946 Geographic Names Information System (GNIS) Oklahoma Ozarks Missouri Kansas Arkansas None.

The DEMs of Westerman and others (2016), which covered the entirety of the Ozark Plateaus aquifer system, were clipped to the smaller study area (11,000 mi2) of this data release. The focus of this data release was to describe the base of each hydrogeologic unit; however, Westerman and others (2016) described hydrogeologic unit tops. Therefore, modifications were made to the DEMs, such as further clipping to match the DEMs to their geologic extents. For example, the base of the Boone aquifer (which is described as the top of the Ozark confining unit in Westerman and others [2016]) was clipped to match the extent of just the Boone aquifer. Other modifications included merging multiple digital elevation models (DEMs) from Westerman and others (2016) because data from Westerman and others divided the Roubidoux aquifer into three units. Contours of the bases of hydrogeologic units were then derived from the modified DEMs using the ArcGIS Contour tool. A contour interval of 50 feet was selected, but a contour interval of 200 feet was used in the southern part of the study area where the units are more steeply dipping. 20190501 Raster Grid Cell 459 254 1 Albers Conical Equal Area 29.5 45.5 -96.0 23.0 0.0 0.0 row and column 2082.6730000000002 2082.673000000001 survey feet North_American_Datum_1983 GRS 1980 6378137.0 298.2572221010042 North American Vertical Datum of 1988 1 feet Explicit elevation coordinate included with horizontal coordinates base_boone_contours.shp Attribute information associated with the data set.
