Water-level contours near La Grange, southeastern Wyoming and an adjacent part of Nebraska, April 30, 1980

This map shows water-level contours for the shallow aquifers in the La Grange area of southeastern Wyoming and adjacent Nebraska as of April 30, 1980. Water-level measurements made on April 30, 1980, provided the principal control for most of the area of the map. Measurements made in April 1979 were used as control for some areas that are remote from centers of pumping. The contours are shown at a 20-foot interval on a map scale of 1:48,000. Irrigation wells, other wells where water-level measurements were made, and springs are located on the map along with surface-water features in the area. (USGS)
