Abstract
This report summarizes data on water levels in 124 observation wells
and provides information on well locations, depths, altitudes, and
aquifers that they tap. Tabulated data include extremes of water levels
for 1981 and for the period of record; pumpage of most major groundwater
users in the State; and quality data on selected wells. The city
of Lansing was the largest reported user of ground-water, pumping 8.6
billion gallons from the Saginaw Formation and glacial deposits.
Description
Data on yield of wells, pumpage, quality of water, and trends of
ground-water levels for the past 5 years are shown in the text.
Many hydrographs are included to illustrate changes in water levels.
Also included are data on municipal water supply. Records of water
levels in observation wells, records of pumpage by most major groundwater
users, and water-quality data from selected wells sampled during
1981 are given in tables 1, 2, and 3. Distribution of observation wells
is shown in figure 1.
