Water Resource Data

Accurate and timely data is crucial to both planning and management of water resources in Kansas. It is a policy of the state that all state agencies with responsibilities affecting water resources of the state shall carry on basic data collection, research and analyses concerning matters relating to the water resources of the state. It is a policy of the state that the Kansas Water Office (KWO) to review and coordinate financial assistance for research that may be provided by federal or state agencies to public corporations concerned with management, conservation and development of water resources to prevent duplication of effort (K.S.A. 82a-901 et seq). The KWO has a mandate to collect and compile information pertaining to a wide range of water issues and, in so doing, collect and compile information obtainable from other agencies, instrumentalities and political subdivisions of the state and the federal government (K.S.A. 74-2608 et seq).

Provided below is information on how to access various sources of water quality and quantity data. The KWO will continue to update this webpage as additional sources of data become available. 

Spatial Data

The Kansas Data Access and Support Center (DASC) catalog includes 175 layers of spatial data that may be downloaded for use in map development or assessments. Water resource spatial data includes aquifer extents, watershed boundaries, National Hydrography Dataset (NHD) and public water supply sites. To view the catalog and access data, visit

Water Quality Data

STORET is a U.S. Environmental Protection Agency (EPA) database of ambient environmental data relating to water quality, biological, and physical data and is used by the Kansas Department of Health and Environment to store some Kansas water quality data. To browse or download STORET data, go to

U.S. Geological Survey Collected Water Information

The USGS collects and maintains a national database of water information, the NWIS. This information ranges from streamflow measurement, to lake levels and ground water levels in certain cases.  It includes data from the High Plains Water-Level Monitoring Study. This information is readily accessible on-line at

The USGS has also collected Water quality data on the High Plains aquifer, as part of the National Water Quality Assessment program (NAWQA) studies on major aquifers.  Water samples from the northern High Plains aquifer were analyzed for 170 water quality constituents.  The study is to provide a broad overview of groundwater quality in the Ogallala portion of the High Plains aquifer.

Weather Data

Kansas State University maintains a Weather Data Library which includes information on precipitation, evapotranspiration, soil temperatures, and other climatological data. The Weather Data Library can be accessed on-line at

Reservoir Conditions

The U.S. Army Corps of Engineers provides daily and historical reports of reservoir conditions for Corps Lakes in Kansas. Data for lakes in the Tulsa District can be viewed on-line at Data for lakes in the Kansas City District can be viewed on-line at

Bathymetric Surveys

The Kansas Biological Survey (KBS) Applied Science and Technology for Reservoir Assessment (ASTRA) program maintains bathymetric and sediment surveys of more than 75 Kansas lakes. To view this information, go to

Kansas Groundwater Information

The Kansas Master Well Index brings together several fresh water well data sets into one comprehensive, accessible data site.  It is under construction by the Kansas Geological Survey, and is on track to be ready for public use in January 2012.   Water well completion records and driller logs (WWC-5) files, water right allocations and annual water use, and depth to water table will be available at the site.  The Master Well Inventory does not replace any data set, but provides the means to access all available information about a groundwater well site in one location.    Once site construction is completed, it will be maintained by the KGS.  To view this site when available, go to:
