Abstract |
This dataset consists of the
locations of wells drilled within Mille Lacs County. The County Well Index
(CWI) is a database that contains information about wells drilled throughout
Minnesota. In this case, a subset of the locations were used to look at the
geological descriptions of these wells. The original CWI file was downloaded
from the Minnesota Geological Survey (MGS) in 2005. |

Abstract |
This dataset consists of the
locations of wells drilled within Mille Lacs County. The County Well Index
(CWI) is a database that contains information about wells drilled throughout
Minnesota. In this case, a subset of the locations was used to look at the
geological descriptions of these wells. The original CWI file was downloaded
from the Minnesota Geological Survey (MGS) in 2006. |
||
Purpose |
This dataset contains the
locations of the wells that were used for this study. Approximately 766 of
the 905 wells contained geological descriptions that were used in this study.

Maintenance and Update Frequency |
The CWI database maintained
by MGS is updated quarterly. This subset was downloaded in 2006 and provides
part of the background information that was used in developing the aggregate

Completeness |
The locational accuracy of
these points varies. Some of the points were field checked down to the meter,
while others are located to the centroid of a 40-acre parcel. Download CWI from the Minnesota
Geological Survey for a complete and up-to-date version and up to date
metadata and full attribute tables. |

||
Lineage |
The geological descriptions
associated with the well locations were used to make interpretations and test
interpretations about the aggregate resources, glacial geology, and bedrock geology
of the area. |
