Ground-water Data for Michigan - 1977
Subject
Groundwater; WellsAbstract
The purpose of this report is to make available the 1977 records of water
levels and related data for the principal aquifers of the State. These records
and data provide a means for evaluating available ground-water supplies. Longterm
records serve as a framework to which short-term records may be related.
Also, water levels in areas of heavy pumping may be compared to levels in areas
of little or no pumping.
This report is written for municipalities, industries, institutions, consultants,
drillers, hydrologists, and other people interested in the groundwater
resources of the State.
Description
Data on the yield of wells, pumpage, quality of water, and trends of groundwater
levels for the past 5 years are shown in the text. Many hydrographs are
included to illustrate changes in water levels. Yield data are given as they
were reported by water departments and consultants. Also included are data on
municipal, public, and industrial water-supply facilities.
Tables 1, 2, and 3 contain records of water levels in observation wells,
well locations, depths, altitudes, aquifers tapped, water-level extremes,
records of pumpage by most major ground-water users in the State, and water
quality data from selected wells sampled during 1975-77. Figure 1 shows
distribution of observation wells in the State.
