Title Regional Hydrogeologic Assessment (Part B) - Southwest Minnesota
Abstract Arc/INFO coverages (as export files), and ARCVIEW shapefiles depicting a variety of characteristics of the ground-water system of the Southwest Minnesota RHA study area.
Purpose Geographic information systems (GIS) layers were created to cartographically depict and spatially analyze data used in the production of the Southwest Minnesota RHA study area, Part B.

A Regional Hydrogeologic Assessment (RHA) is a systematic study of a multi-county region's geologic and ground-water resources. Geologic studies focus on near-surface deposits. Ground-water studies include flow systems, aquifer capacity, ground-water chemistry, and sand and gravel deposits. Sensitivity of near ground-water systems is estimated.

Attribute Accuracy
Logical Consistency Data are topologically correct using Arc/Info 7.1.1
Completeness Complete
Horizontal Positional Accuracy Not Available
Vertical Positional Accuracy Not Applicable
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. Drillers send water well logs to the Minnesota Geological Survey, where they are reviewed, interpreted, and entered 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 and chemistry of selected wells. These studies, combined with pre-existing data, are used to create models of water-table hydrogeology (elevation, potentiometric surface, potential yield, flow direction), and sensitivity of the near-surface ground water system to pollution.

Creation of GIS layers: Using a variety of techniques, data is converted into Arc/INFO coverages or ARCVIEW shapefiles for cartographic display and spatial analysis.

Section 5 Entity and Attribute Information Top of full metadata Top of page
Entity and Attribute Overview 6 GIS data layers were created by DNR Waters for The Southwestern Minnesota RHA, Part B, which includes two plates:

Plate 3 - Hydrogeology of the Water Table
Plate 4 - Sensitivity of the Water Table to Pollution

Both Arc/Info coverages (as export files) and ARCVIEW shapefiles are available.

Coverages used in more than one plate:

CHEMPT - Wells sample by DNR staff for chemistry

Coverages used in Plate 3: Hydrogeology of the Water Table:

WTELLN - Water table elevation
WTFLOW - Water table flow direction

Coverages used in Plate 4: Sensitivity of the Water Table to Pollution:

GWSL2PY - Sensitivity of the water table to pollution
SBORDOT - Soil borings from the Mn Department of Transportation
SSOPT - Seismic sounding locaitons
