Ground-water Data for Michigan - 1986
Subject
GroundwaterAbstract
Water levels, locations, depths, and aquifers tapped are given for 112
observation wells. Tabulated data include extremes of water levels for
calendar year 1986 and for the period of record, pumpage of most major groundwater
users in the State, and water-quality data from selected wells. The
largest reported user of ground-water, the city of Lansing, pumped 7.6 billion
gallons from the Saginaw Formation and glacial deposits in 1986.
Description
This report makes available, through 1986, the records of water levels
and related data for the principal aquifers of Michigan. Data on yield of
wells, pumpage, quality of water, and hydrographs of ground-water levels for
the past 5 years are shown in the text. Yearly hydrographs are included to
illustrate seasonal changes in water levels. Records of water levels in
observation wells, records of pumpage by most major ground-water users, and
water-quality data from selected wells sampled during 1986 are given in tables
1, 2, and 3. 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.
