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. The information is analyzed, and displayed, and organized using GIS technology. | | Time Period of Content Date | 1995-1996 | | Currentness Reference | Complete | | Progress | Complete | | Maintenance and Update Frequency | None planned | | Spatial Extent of Data | Upper Minnesota River basin area in Minnesota, including: all of Chippewa, Lac Qui Parle, Swift, and Yellow Medicine counties, the southern portion of Big Stone county, western portions of Kandiyohi and Renville counties, northern portions of Lincoln, Lyon, and Redwood counties. | | West Bounding Coordinate | 207,977 | -- | | East Bounding Coordinate | 274,044 | -- | | North Bounding Coordinate | 5,267,921 | -- | | South Bounding Coordinate | 5,098,424 | -- | | Place Keywords | Chippewa, Lac Qui Parle, Swift, Yellow Medicine, Big Stone, Kandiyohi, Renville, Lincoln, Lyon, and Redwood counties; Minnesota River; Minnesota | | Theme Keywords | Water Chemistry, Wells, Ground Water, Surface Water, Geology, Pollution Sensitivity, Aquifer Yield, Potentiometric Surface, Water Table, Hydrogeology | | Theme Keyword Thesaurus | -- | | Access Constraints | None | | Use Constraints | Users may wish to verify critical information; sources include both the references here and information on file in the offices of the Minnesota Geological Survey and the Department of Natural Resources.

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. | | Source Scale Denominator | 200,000 |
