Data on the yield of wells, pumpage, quality of water, and trends
of ground-water levels for the past 5 years are shown in the text.
Many hydrographs are included to illustrate natural changes in water
levels. Also included are data on municipal water-supply sources.
Tables 1, 2, and 3 contain records of water levels in observation
wells, records of pumpage by most major ground-water users, and water
quality data from selected wells sampled during 1979. Figure 1 shows
distribution of observation wells.
