Ground-water Data for Michigan - 1989
Subject
GroundwaterAbstract
Water levels, locations, depths, and aquifers tapped are given for 108
observation wells. Tabulated data include a listing of ground-water reports
in Michigan, extremes of water levels for calendar year 1989 and for the
period of record, pumpage of most major ground-water users in the State, and
water-quality data from selected wells. In 1989, the two largest municipal
users of ground water were Lansing and Kalamazoo. Lansing pumped 7.2 billion
gallons from the Saginaw Formation and glacial deposits; Kalamazoo pumped 6.7
billion gallons from glacial deposits only.
Description
This report provides records of water levels and related data collected
during 1989 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, and records of pumpage by most major ground-water users during 1989 are
given in tables 2 and 3. Distribution of observation wells is shown in figure
1. Locations of wells sampled for water-quality data and years sampled are
shown in figure 2.
