The Arbuckle aquifer is an extensive aquifer that contains mostly saline water and that immediately overlies Precambrian ' basement ' rocks throughout Kansas, except for major uplift areas where it has been removed by erosion. In the southeast part of the state, it is a major freshwater aquifer. The upper part of the Arbuckle contains significant oil and gas reservoirs in central and...

Data utilized in preparing an interpretive hydrogeologic report on the Dakota aquifer system in Nebraska are summarized. The study area is a 370,000 sq mi area that includes all of Kansas and Nebraska and parts of Arkansas, Colorado, Missouri, New Mexico, Oklahoma, and Texas. The broad objective for each Regional Aquifer-System analysis (RASA) study is to assemble geologic, hydrologic...

Hydrologic data were compiled for the South-Central hydrogeology study, which covers an area of approximately 5,600 square miles in south-central Nebraska. Data pertain to the groundwater, surface water, climate, land use, and pumpage and precipitation at water use sites in the study area. Groundwater data include water level elevations from three mass measurements of wells and water...

Saline water discharges from the alluvial aquifer into the Smoky Hill and Solomon Rivers between New Cambria and Solomon in central Kansas. Chloride concentrations in the Smoky Hill River sometimes exceed 1,000 mg/L during low flow conditions. The source of saline water is the underlying Wellington aquifer, a zone of halite and gypsum dissolution, subsidence, and collapse along the...

Continuing studies are being made in west-central Kansas to provide up-to-date information that will aid in the management of groundwater for irrigation. The results are presented of the sixth in a series of studies that used a statistical technique called kriging, to produce hydrologic maps. The kriging technique interpolates water level altitudes at the center of each 1 sq mi section...

The High Plains aquifer in Kansas is part of a regional aquifer system that extends into Colorado, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. The aquifer in Kansas underlies an area of 31,000 square miles in the western and south-central part of the State. The aquifer is a hydraulically connected assemblage of unconsolidated water-bearing deposits. In western...

Water year 1984 was a year of extreme hydrologic conditions. For the third consecutive year, precipitation and resulting runoff were well above long-term averages in most of the Nation and as much as 400 percent above average in the Southwest. National flood damages during the year were the third highest in a 10-year period (1975-84) an estimated $3.5 to $4 billion. In many of the larger...

Data collection programs need to be re-examined periodically in order to insure their usefulness, efficiency, and applicability. The possibility of time trends in sediment concentration, in particular, makes the examination with new statistical techniques desirable. After adjusting sediment concentrations for their relation to streamflow rates and by using a seasonal adaptation of...

The chemical quality of groundwater and base flow in three alluvial valleys in Kansas has been changed as a result of 10 or more years of irrigation. Sulfate concentrations in groundwater in the Prairie Dog Creek valley statistically larger during 1981-82 than before irrigation began. Concentrations of calcium, bicarbonate, sulfate, and dissolved solids in groundwater in the Republican...

During the past few years, water-resource management in Kansas has undergone reorientation with the creation of the Kansas Water Authority and the Kansas Water office. New thrusts toward long-term goals based on the Kansas State Water plan demand strong communication and coordination between all water-related agencies within the State. The seminar discussed in this report was an initial...

A two-dimensional finite difference computer model was used to project changes in the potentiometric surface, saturated thickness, and stream aquifer leakage in an alluvial aquifer resulting from four instances of projected groundwater development. The alluvial aquifer occurs in the South Fork Solomon River valley between Webster Reservoir and Waconda Lake in north-central Kansas. In the...
