Hydrologic data for the south-central area, Nebraska

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 quality information from 68 water quality sampling sites. Surface water data include average annual stream flows and average October through December streamflows at U.S. Geological Survey gaging stations, canal diversions, and seepage from canals and reservoirs. Climatic data include monthly precipitation records for eight weather stations and evaporation data from four reservoirs. Land use data were compiled for agricultural land uses, by county, from 1940 through 1981. Water use site data include water levels at each of 18 sites, soil information for those sites with complete precipitation and pumpage records, and precipitation and groundwater pumpage information for each site.
