Alluvial Aquifer Extent

This data shows the extents of the alluvial aquifers in Kansas for the [Kansas Geological Survey] - Geohydrology. The alluvial aquifers consist of unconsolidated Quaternary alluvium and contiguous terrace deposits. The data was developed from 1:500,000-scale information. The data used to construct this representation are from the state geologic map of Kansas. This data was developed as part of a larger project to define the extent, chemical quality, and flow systems within the major aquifers in Kansas. The data presented can be used to delineate the extent of the alluvial aquifers. Such information is valuable in studies focusing on the management of water resources in these aquifers and other hydraulically connected sources of water.
Geologic Terrains

Geologic terrains are the same as major, minor, and sub basins in Kansas. The geologic terrain boundaries in Kansas are based on either major faults or sharp changes in depth. The exception to this is the boundary between Cherokee and Forest City, where an older, existing boundary was used. For modeling purposes, the polygons overlap along the Nemaha Uplift region and extend beyond the Kansas borders. This data was generated by the [Kansas Geological Survey]'s Energy Program.

Statewide 50 ft Elevation Contours

This dataset includes generalized elevation contour lines shown on map M-129B, “[Surface topography of Kansas: Elevation contours and hydrography (2025)]", published by the [Kansas Geological Survey]. Elevation contour lines were derived from 2015–2018 lidar data provided by the Kansas Data Access and Support Center (DASC) that were mosaicked and processed to 10-meter resolution by the Kansas Biological Survey. Generalized contour lines were generated with the contour raster function tool in ArcGIS Pro 3.4. Map produced by the Cartographic Services unit of the Kansas Geological Survey. This map displays elevation, the vertical height of the land surface above sea level, using contour lines that connect points of equal value. Contour lines that are more closely spaced together represent steeper slopes. The contour interval of this dataset is 50 feet and includes contour lines classified as index (every 200 feet), intermediate (100 feet), and supplemental (50 feet). Lines classified as supplemental in the dataset were not shown on M-129B due to scale but were generated during map production. The contour lines in this dataset are generalized for statewide scale; the recommended scale range of use is 1:250,000-1:5,000,000. This dataset covers Kansas and portions of Missouri near the Missouri River valley. More detailed (2-foot interval) contour lines derived from Kansas lidar data can be downloaded per county in the [Download Kansas 2-foot Contours] map.

State Surficial Geologic Units (M-118)

This dataset includes geologic unit polygons as shown on map [M-118, “Surficial Geology of Kansas (2008)”]. The geologic units occur at or near the surface of Kansas and are classified according to age and sediment or rock type. Statewide geologic maps of Kansas are periodically published by the Kansas Geological Survey to incorporate new geologic information and up-to-date rock classifications. The first such map was published in 1896 with subsequent 1937, 1964, 1991, and 2008 editions. The 1964 edition – M-1, “Geologic Map of Kansas” – was digitized to produce the 1991 map and first digital statewide geology dataset. The 2008 revision, M-118, includes a shift in the boundary between the Pennsylvanian and Permian bedrock, redefined by the geologic community. M-118 map data was converted to the [U.S. Geological Survey GeMS] format, 2023-2024. Published by the [Kansas Geological Survey].
Type Wells

This layer shows locations of oil and gas wells that were designated to be part of the Type Logs Project. This project was conducted by the Energy Research Department of the [Kansas Geological Survey]. This project created extended data for wells. Some of the extended data includes the well tops for each well and the owner of the tops, the result of the Type Log Committee evaluation of the tops, the Stratigraphic Units for the Type Log Project & CO2 Project, the Committee members for the Type Log Project that are selecting & evaluating the tops, and Log LAS 3.0 files. This type Log LAS 3.0 file contains the Log ASCII Standard (LAS) 3.0 File Information for the final files containing the Log Data, Tops Data and, if present, the Geologist Report Data. These files are part of the final deliverables for the Type Log Project and are also part of the CO2 Project mapper program to allow the user to build General Cross Sections with these files.

Sources: EIA-191, Monthly Underground Gas Storage Report to improve accuracy of locations other sources were used including [Homeland Infrastructure Foundation-Level Data (HIFLD)], [EPA Facility Registry Service (FRS)], [National Pipeline Mapping System Public Viewer], company websites and satellite imagery. The data has been clipped to the State of Kansas by the [Kansas Geological Survey]. This layer is intended for general reference. To access the most up-to-date data, access the Monthly Underground Gas Storage Report.
Oil and Gas Leases

An oil and/or gas lease is an agreement between a mineral owner (lessor) and a company (lessee) in which the owner grants the company the right to explore, drill and produce oil, gas, and other minerals below the surface of the earth. Oil and gas leases are created so that property owner can maintain their mineral rights while leasing their land to an extraction company. The [Kansas Geological Survey] maintains and publishes this GIS data. The Kansas Department of Revenue is the data originator, and they send updates to the KGS monthly.
Dakota Aquifer

These data show the elevation in feet above mean sea level of the base and top, the extent, the elevation in feet above mean sea level for the potentiometric surface, and the concentration in milligrams per liter (mg/L) of total dissolved solids in ground water of the Dakota aquifer in Kansas. The data presented can be used to delineate the dominant features of the regional flow system within the Dakota aquifers. Such information is valuable in studies focusing on the management of water resources in the Dakota aquifers and other hydraulically connected sources of water. This data is from the [Kansas Geological Survey] - Geohydrology. The Dakota aquifer consists of sandstone bodies in the Cretaceous Dakota Formation and Cheyenne Sandstone. The coverages were developed from 1:100,000-, 1:175,000-, 1:500,000-, and 1:1,000,000-scale information. The data used to construct the top and base altitude coverages are from oil and gas exploration and production wells penetrating the Dakota aquifer. The data used to map the altitudes consist primarily of gamma ray logs and supplemented by drillers' logs in the Salina basin of north-central Kansas.
Oil Production by Section

Cumulative oil production in Kansas aggregated by section. Production measurement in barrels (bbls) and represents total production reported through the most recent quarter. The production data is reported to the Kansas Department of Revenue by oil and gas lease. This data is then passed to the KGS and aggregated by section-township-range. Data managed by the [Kansas Geological Survey] and updated quarterly. A point representation of this layer is available on request, please contact kgs.gis@ku.edu.
Kimberlite and Lamproite (M-118)

This dataset depicts the approximate location of kimberlite and lamproite deposits found at the surface as shown on map [M-118, “Surficial Geology of Kansas (2008)”]. Site names and additional data sources are included as attributes. Kimberlites and lamproites are mafic to ultramafic (contain little to no quartz and feldspar, common crustal minerals) igneous rocks formed when magma from the mantle intrudes upward into existing sedimentary rock. Though diamonds may be present in these types of deposits, none have been found in Kansas. Kimberlites are located in Riley and Marshall counties. Lamproites have been found in Woodson and Wilson counties. These rocks were emplaced during the Cretaceous period. M-118 map data was converted to the [U.S. Geological Survey GeMS] format, 2023-2024. Published by the [Kansas Geological Survey].
Aquifer Extents

These features delineate the extents of the aquifers in Kansas as identified by the [Kansas Geological Survey]. The data used to construct this coverage are from the state geologic map of Kansas. These features were developed as part of a larger project to define the extent, chemical quality, and flow systems within the major aquifers in Kansas. The data presented can be used to delineate the extent of the aquifers. Such information is valuable in studies focusing on the management of water resources in these aquifers and other hydraulically connected sources of water.
State Geology Contacts (M-118)

This dataset includes geologic contact lines as shown on map [M-118, “Surficial Geology of Kansas (2008)”]. A geologic contact is a planar surface that bounds a geologic unit (except faults). A contact delineates the stratigraphic position where the properties and characteristics of one geologic unit change to those of another. M-118 map data was converted to the [U.S. Geological Survey GeMS] format, 2023-2024. Published by the [Kansas Geological Survey].
Approximate limit of the Hutchinson Salt Member (Schumaker, 1966)

This dataset represents the extent of the Hutchinson Salt Member of the Permian Wellington Formation. This data has been digitized from past [Kansas Geological Survey] publications. More information can be found on the [Hutchinson Salt Member and the Hutchinson Response Project] page of the KGS website. The map was created by the KCC Conservation Division in 1991 as ‘Figure 1, Sensitive Groundwater Areas’. [https://chasm.kgs.ku.edu/ords/bibliography.ofr4.MainDate] Title: Figure 1, Sensitive ground water areas (as referenced in K.A.R. 82-3-600 et.seq.) Author: Collins, D.R.; and Ross, J.A.

Master Well Inventory

The Kansas Master Ground-water Well Inventory (MWI) is a central repository that imports and links together the State's primary ground-water well data sets- KDHE's [WWC5], KDA-DWR's [WIMAS], and KGS' [WIZARD] into a single, online source. The most "accurate" of the common source fields are used to represent the well sites, for example- GPS coordinates if available are used over other methods to locate a well. The MWI maintains the primary identification tags to allow specific well records to be linked back to the original data sources. This data is compiled by the [Kansas Geological Survey]. For more information, please see the [Groundwater Master Well Inventory ]page.
Ozark Aquifer

These digital maps contain information on the altitude of the base, top, and extent of the Ozark aquifer in Kansas. This data is from the [Kansas Geological Survey] - Geohydrology. Potential uses of these digital maps include: studies addressing the location, quantity, quality, use, management, and protection of ground-water resources in Kansas. The Ozark aquifer consists of weathered and sandy dolomite and limestone of Ordovician and Cambrian age and includes the Arbuckle Group. The digital map was developed from 1:500,000- and 1:1,000,000-scale source information. The altitude for the base and top contour interval is 100 feet.
Water Wells WWC5

The Water Well Completion Form Database (WWC5) contains information from records submitted by water well drillers to the Kansas Department of Health and Environment. Data is compiled by the [Kansas Geological Survey]. Drilling companies are mandated by state legislation under the Kansas Groundwater Exploration and Protection Act (KSA 82a-1201 et seq.) to provide information pertaining to the location, type, use, casing, nearest source of contamination, and so on of the well drilled using the WWC5 form. No water quality data is provided in this database. A good portion of the archived WWC5 records are in the form of electronically scanned images of the forms themselves. As such, the only standard database items entered into an Oracle RDBMS relate to the location information of the WWC5 wells, use of the well, when the well was completed, status of the wells, well depth, static water elevation, and the name of the drilling company servicing the site.
Class II Wells

Class II injection wells come in two varieties: disposal wells and secondary/enhanced oil recovery wells. Disposal wells are used to inject fluids into rock formations that do not produce oil or gas. The formations are isolated from usable quality groundwater and are sealed above and below by unbroken and impermeable rock formations. Secondary/enhanced oil recovery wells are used to inject fluids into formations/reservoirs that produce oil or gas. The formations are also isolated. Injection of fluid into these formations often allows for increased recovery of oil or gas reserves. For more information, see the Kansas Corporation Commission's [FAQ on Class II Injection Wells]. To query Class II wells, see the interactive [KGS query tool]. Class II injection wells in Kansas are regulated by the Kansas Corporation Commission. The data is collected and distributed by the [Kansas Geological Survey].
