Abstract
The purpose of this report is to make available the records of water levels in principal aquifers of the State through 1975 and to compile other related data, such as records of ground-water pumpage. Also included in the report are data on municipal, public, and industrial water-supply facilities. Records of water levels in areas of heavy pumpage and in areas where changes are principally due to natural influences are illustrated or tabulated to allow comparison between these types of water-level fluctuations. The water levels and related data provide a record for the evaluation of available ground-water supplies. The long-term records serve as a framework to which short-term records may be related. This report is written for persons, municipalities, industries, institutions, consultants, drillers, and hydrologists interested in the ground-water resources of the State.
Description
Table 1 contains records of measurements of water levels in observation wells, well locations, depths, elevations, aquifers tapped, and water level extremes for the past and for 1975. Figure 1 shows density of observation wells in the State. Table 2 contains records of pumpage by most major ground-water users in the State in 1975. Many hydrographs are included in the report to illustrate changes in water levels. Most illustrations also show the effects of ground-water pumpage on water levels. Supplementary data on the yield of wells, pumpage, quality of water, and trends of ground-water levels for 1975 and for part of the preyious record are shown in summary form in the text. Yield data are given as they were reported by water departments and consultants.
