  • About the Edition

    A calibrated steady-state, finite-difference, ground-waterflow model was constructed to simulate ground-water flow in three glaciofluvial aquifers, defined in this report as the upper, middle, and lower aquifers, in an area of about 114 mi2 surrounding the city of Grand Rapids in north-central Minnesota. The calibrated model will be used by Minnesota Department of Health and communities in the Grand Rapids area in the development of wellhead protection plans for their water supplies. The model was calibrated through comparison of simulated ground-water levels to measured static water levels in 351 wells, and comparison of simulated base-flow rates to estimated base-flow rates for reaches of the Mississippi and Prairie Rivers. Model statistics indicate that the model tends to overestimate ground-water levels. The root mean square errors ranged from +12.83 ft in wells completed in the upper aquifer to +19.10 ft in wells completed in the middle aquifer. Mean absolute differences between simulated and measured water levels ranged from +4.43 ft for wells completed in the upper aquifer to +9.25 ft for wells completed in the middle aquifer. Mean algebraic differences ranged from +9.35 ft for wells completed in the upper aquifer to +14.44 ft for wells completed in the middle aquifer, with the positive differences indicating that the simulated water levels were higher than the measured water levels. Percentage errors between simulated and estimated base-flow rates for the three monitored reaches all were less than 10 percent, indicating good agreement. Simulated ground-water levels were most sensitive to changes in general-head boundary conductance, indicating that this characteristic is the predominant model input variable controlling steady-state water-level conditions. Simulated groundwater flow to stream reaches was most sensitive to changes in horizontal hydraulic conductivity, indicating that this characteristic is the predominant model input variable controlling steady-state flow conditions.

    table. It then flows under gravity through local, intermediate and regional flow systems within the aquifers. Local flow systems have flow paths of less than 5 km. They mostly occur in upper aquifers or the unconfined fractured rock of the lower aquifers or basement. These aquifers respond quickly to changes in rainfall, extraction or land use.

Pennsylvanian-aged, coarse-grained clastic rocks are important aquifers in several central Lower Michigan counties. Dr. Alan E. Kehew, in collaboration with the Michigan Geological Repository for Research and Education, is completing work on a predictive model for aquifer geometry, spatial distribution and controls on reservoir properties.

The groundwater supply, especially that in the bedrock, is badly depleted along Lake Michigan between Muskegon and Petoskey and from the southern state line to the thumb area in southeastern Michigan.

Portions of the Upper Peninsula have both quality and quantity problems, especially the igneous rock areas of the western Upper Peninsula.

Aquifers: Map of the Principal Aquifers of the United States The areal and vertical location of the major aquifers is fundamental to the determination of groundwater availability for the Nation. An aquifer is a geologic formation, a group of formations, or a part of a formation that contains sufficient saturated permeable material to yield.
