Ground-water Data for Michigan - 1983
Subject
Groundwater; WellsAbstract
Water levels, locations, depths, and aquifers tapped are given for 115
observation wells. Tabulated data include extremes of water levels for 1983 and
for the period of record, pumpage of most major ground-water users in the State,
and quality data on selected wells. The largest reported user of ground-water,
the city of Lansing, pumped 8.1 billion gallons from the Saginaw Formation and
glacial deposits.
Description
This report makes available, through 1983, the records of water levels and
related data for the principal aquifers of the State. It is written for
municipalities, industries, institutions, consultants, drillers, hydrologists
and other people interested in ground-water resources.
Data on 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. Records of water levels in
observation wells and records of pumpage by most major ground-water users, are
given in tables 1 and 2. Distribution of observation wells is shown in figure 1.
Location of wells sampled for water-quality data and years sampled are shown in
figure 2. No water-quality data was obtained during 1983.
