Description: Counties that have had the DFIRM (Digital Floodplain Mapping) created. Some Counties may of had only a portion, usually around a city, of their floodplain digital. More counties are being added. Data current as of July 2014. More information can be obtained from https://msc.fema.gov/portal.

Description: Abstract: This coverage shows the extents of the alluvial aquifers in Kansas. The alluvial aquifers consist of unconsolidated Quaternary alluvium and contiguous terrace deposits. The coverage was developed from 1:500,000-scale information. The data used to construct this coverage are from the state geologic map of Kansas.
Description: Abstract: These digital maps contain information on the altitude of the base, the extent, and the potentiometric surface (i.e. altitude of the water table) of the Glacial-drift aquifer in Kansas. The Glacial-drift aquifer consists of surficial sand and gravel deposits as well as sand and gravel buried beneath unconsolidated till and loess of Pleistocene age. The bedrock digital map was developed from 1:125,000-scale source information with a contour interval of 50 feet. The extent map was developed from 1:500,000-scale source information. Included as part of the digital extent map are areas where older rocks crop out within the aquifer boundary (fensters) and areas where the glacial-drift aquifers have little or no saturated thickness. The potentiometric surface digital map was developed at a scale of 1:200,000- from water-level data collected and compiled by the Kansas Geological Survey and from data available from the U.S. Geological Survey's National Water Information System (NWIS). The potentiometric surface contour interval is 50 feet. These digital maps were produced in cooperation with the Kansas Water Office as part of the State Water Plan.
Description: These digital maps contain information on the altitude of the base and top, the extent, and the potentiometric surface of the Ozark aquifer 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. The potentiometric surface contour interval is 50 feet
Description: Abstract: These coverages 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 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. Most of the data used to construct the potentiometric surface are from wells screened in the Dakota Formation. Elsewhere, the data are derived primarily from measurements made in wells screened in the Cheyenne Sandstone. The potentiometric surface contour interval is 100 feet. The total dissolved solids coverage's data are from the Dakota Formation, but also includes analyses of ground water from wells screened in the Cheyenne Sandstone and Longford Member of the Kiowa Formation. Its contour interval is variable and increases with increasing concentration.
Description: Abstract: These digital maps contain information on the altitude of the base, the extent, and the 1991 potentiometric surface (i.e. altitude of the water table) of the High Plains aquifer in Kansas. Included in the High Plains aquifer are the Ogallala, Great Bend, and Equus Beds aquifers. The High Plains aquifer consists of unconsolidated Pleistocene, Pliocene, and Miocene silt, clay, sand, and gravel of fluvial and eolian origin and any alluvial deposits directly overlying the unconsolidated Pleistocene, Pliocene, and Miocene deposits. The digital maps were developed from 1:500,000-scale source information. The altitude of the base and potentiometric surface contour interval is 50 feet with supplemental 25 foot contours for potentiometric only.
Description: USGS High Plains aquifer complete for the USA. The Ogallala Aquifer occupies the High Plains of the United States, extending northward from western Texas to South Dakota. The Ogallala is the leading geologic formation in what is known as the High Plains Aquifer System.
