Abstract

This dataset consists of the locations of wells drilled within Meeker 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 origianl CWI file was downloaded from the Minnesota Geological Survey (MGS) in 2003.

County Well Index (CWI) Well Locations, Meeker County, 2003

Abstract

This dataset consists of the locations of wells drilled within Meeker 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 origianl CWI file was downloaded from the Minnesota Geological Survey (MGS) in 2003.

Purpose

This dataset contains the locations of the wells that were used for this study. Approximately 695 of the 731 wells contained geological descriptions that were used in this study.

Associated Data Sets

The County Aggregate Mapping Program dataset for Meeker County is included in the file meekdata.zip from the MN DNR Aggregate Mapping web page:
http://www.dnr.state.mn.us/lands_minerals/aggregatemaps.html
The dataset is also available as aggregate resource data layers stored at drive:\data\resource on the CD (where 'drive' is the CD reader or writer drive on the PC). The data layers include data on sand and gravel potential, crushed stone potential, field observations, rock piles, and test pit quality data.
The CWI wells data are included in a simplified version (i.e., a number of fields have been dropped from the file since these fields were not used for this project), since they are part of the background information that was used in developing the mapping units for this project. For the full CWI dataset, contact the Minnesota Geological Survey.

Lineage

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

Entity and Attribute Overview

These points represent the locations of individual wells drilled throughout Meeker County.

Entity and Attribute Detailed Citation

mcwiwells_att.htm

Attribute values can be found in the table mcwiwells_att.htm. If this table hotlink cannot be found by your browser, you can find this file stored in the same location (i.e., drive:\docs) as this metadata record.

An additional table, cwistrat.dbf, is a subset of the STRAT table of the CWI database. The cwiwells shapefile relates to the cwistrat.dbf table as a one-to-many relate on the relateid field. The additional table contains only those fields that were considered directly applicable to developing aggregate resource mapping units for this project. The descriptions were made by different drillers and geologists, with the information ranging from very good and complete to very poor and vague. Descriptions can vary from well to well, due to different individuals completing the well logging. As an example of the detail found in these descriptions: detailed descriptions often cover 5 to 10 feet of thickness per glacial material type or bedrock type. Less detailed descriptions may say 0-240 feet glacial drift and 240-360 feet bedrock.

The definition of the fields found in mcwistrat.dbf are included in the mcwiwells_att.htm file.
