Water-level altitudes at the center of each 1-square-mile section (1,859 values) in Western Kansas Groundwater Management District No. 1 were interpolated from 292 measured water levels using a statistical technique referred to as kriging. The kriging technique involves the use of a series of computer programs that convert selected geohydrologic data into map form. A map that illustrates the percentage change in saturated thickness of the High Plains aquifer from 1950 to average 1982-84 in west-central Kansas was constructed by comparing kriged water-table altitudes (based on average 1982-84 data) with estimated 1950 water-table altitudes and bedrock-surface altitudes.
