Most of the streams is west-central Kansas are ephemeral. Natural recharge to the alluvial aquifers underlying these streams occurs during periods of storm runoff in the ephemeral channels. Proposed flood-retarding structures within the basin will alter the downstream runoff characteristics in these channels by reducing the peak flow and increasing the flow duration. Information...

Water-resources data for the 1987 water year for Kansas consist of records of stage, discharge, and water quality of streams; elevation, contents, and water quality of lakes or reservoirs; and water levels and water quality of ground-water wells. This report contains records for water discharge at 140 gaging stations; elevation and contents at 24 lakes or reservoirs; water quality at 31...

The formation of carcinogenic trihalomethanes during the treatment of public surface water supplies has become a potentially serious problem. The U. S. Geological Survey, in cooperation with the Kansas Department of Health and Environment , investigated the potential for trihalomethane formation in water from 15 small, public water supply lakes in eastern Kansas from April 1984 through...

Obtaining a sample of groundwater that accurately represents the concentration of a chemical constituent in an aquifer is an important aspect of groundwater-quality studies. Varying aquifer and constituent properties may cause chemical constituents to move within selectively separate parts of the aquifer. An experiment was conducted in an agricultural region in south-central Kansas to...

Wastes generated at nine hazardous-waste sites in Kansas were disposed in open pits, 55-gal drums, or large storage tanks. These disposal methods have the potential to contaminate groundwater beneath the sites, the soil on the sites, and nearby surface water bodies. Various activities on the nine sites included production of diborane, transformer oil waste, production of soda ash, use of...

Hydrologic data related to water level measurements made in observation wells in western and south-central Kansas are listed. The measurements were made in midwinter when pumping was minimal and water levels had recovered, for the most part, from the effects of pumping during the previous irrigation season. Annual hydrologic data are provided for relating water level changes from a '...

A 12.3-acre, fully urbanized, residential land-use catchment was instrumented by the U. S. Geological Survey in Topeka, Kansas. Hydraulic instrumentation for flow measurement includes two types of flumes, a pipe-insert flume and a culvert-inlet (manhole) flume. Samples of rainfall and runoff for water-quality analyses were collected by automatic, 3-liter, 24-sample capacity water samples

The U.S. Geological Survey, in cooperation with the Western Kansas Groundwater Management District No. 1, established data collection instrumentation around an earthen dam in Scott County , west-central Kansas. The dam was placed on an ephemeral drainage to monitor water storage behind the dam, precipitation, and groundwater levels in the vicinity. This report briefly describes the site...

As assessment of hydrologic factors and agricultural practices that may affect the leaching of agricultural chemicals to groundwater was conducted to evaluate the extent and severity of chemical contamination of groundwater resources in Kansas. The climate of a particular area determines the length of the growing season and the availability of water, at the surface and in the ground, for...
