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.
