OriginatorMinnesota Department of Natural Resources, Division of Waters
TitleCrow Wing County Geologic Atlas, Part B
Minnesota Clearinghouse ID--
AbstractArcGIS shapefiles depicting a variety of characteristics of the ground water system of Crow Wing County, Minnesota
Purpose

Geographic information systems (GIS) layers were created to cartographically depict and spatially analyze data used in the production of the Crow Wing County Geologic Atlas, Part B.

A County Geologic Atlas (CGA) is a systematic study of a county's geologic and ground-water resources. Geologic studies include both near-surface deposits and bedrock. Ground-water studies include flow systems, aquifer capacity, ground-water chemistry, and sand and gravel deposits. Interpretation of sensitivity to pollution is also part of a CGA.

Lineage

Review of available data:
Investigations begin with a review of existing information, such as earlier geologic maps, soil maps, hydrologic reports, and information provided by well drillers. Minnesota Geological Survey staff review and interpret driller's logs, and enter the data into the County Well Index (CWI), an interactive data base of water-well information.

Collection of data from the field:
Field studies are conducted to measure static water level elevations in wells and chemistry of selected wells. These studies, combined with pre-existing data, are used to create models of water-table and bedrock hydrogeology (elevation, potentiometric surface, capacity, flow direction), and sensitivity of ground water system to pollution.

Creation of GIS layers:
Using a variety of techniques, data are converted into ArcGIS shapefiles, grids, or feature classes for cartographic display and spatial analysis. Metadata for individual layers contain more detailed lineage information.

Entity and Attribute Information

Entity and Attribute Overview

The Crow Wing County Geologic Atlas, Part B consists of 11 separate GIS data layers divided into four plates:

Plate 7 - Hydrogeology of the Buried and Surficial Aquifers
Plate 8 - Hydrogeologic Cross Sections
Plate 9 - Pollution Sensitivity of the Buried and Surficial Aquifers
Plate 10 - Interaction of Lakes and Ground Water

ArcGIS shapefiles are available.
