Ground-water Data for Michigan - 1984
Subject
Groundwater; WellsAbstract
Water levels, locations, depths, and aquifers tapped are given for 114
observation wells. Tabulated data include extremes of water levels for 1984
and for the period of record, pumpage of most major ground-water users in the
State, and water-quality data from selected wells. The largest reported user
of ground-water, the city of Lansing, pumped 8.2 billion gallons from the
Saginaw Formation and glacial deposits.
Description
This report makes available, through 1984, the records of water levels
and related data for the principal aquifers of the State. 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. 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 1984 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.
