Ground-water Data for Michigan - 1974
Subject
Groundwater; WellsAbstract
The purpose of this report is to make available the records of water
levels in principal aquifers of the State through 1974 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 1974. Table 2 contains records of pumpage by
most major ground-water users in the State in 1974.
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, storage facilities,
treatment, quality of water, and trends of ground-water levels for 1974
and for part of the previous record are shown in summary form in the text.
