Groundwater Inventory and Mapping Project, a cooperative effort between the Water Bureau - Michigan Department of Environmental Quality, USGS - Michigan Water Science Center and Michigan State University - Institute of Water Research, RS&GIS and Biosystems and Agricultural Engineering. This project was mandated by P.A. 148 (Michigan Acts of 2003). Major funding was provided by MDEQ, supplemented with additional funds from the USGS Cooperative Water Program.

Title: Wellogic
Description:
Abstract:
The data in this file was obtained from Wellogic, the Michigan Department of Environmental Quality Statewide Ground Water Database (SGWD). Wellogic contains approximately 425,000 water well records found within the State of Michigan, and although it represents the best available data, it cannot be considered a complete database of all the wells or well records in existence. The well files were downloaded by county and merged together to create a statewide file. In the merge process any well that fell outside of its designated county boundary was removed from the original data set. Approximately 325,000 records were used in this file after the inconsistent point locations were removed. A series of additional attributes were added to the database, this is a brief overview of how the well locations were processed: A GIS data update utility created at MSU was used to process and merge the county wells; this also added many glacial drift and rock well fields, and percentages for aquifer drift material based on the existing Wellogic and lithology database information. Next the percentages of aquifer material and trend information were calculated for the drift index. These fields were used by the USGS to further calculate the wells transmissivity and yield values. A detailed account of these processes can be found later on in this document.
Purpose:
The Wellogic data base is the richest source of well data available in the State of Michigan. From this well data much information can be derived about the groundwater characteristics. This shape files was downloaded from the Wellogic database on 5/24/2005 and serves as the master well file for the Groundwater Inventory and Mapping project.

Process_Description:
Many calculations were made to facilitate mapping and to allow for spatial interpolation between water well log glacial aquifer properties. The creation and analysis of this data involved complex processes that are described in the technical report that is available at <http://gwmap.rsgis.msu.edu/>. Please refer to attached data dictionary for full field descriptions.

Process_Step:
Process_Description:
Well data by county was downloaded from the Michigan Geographic Data Library on May 24, 2005 using a download tool created by Bill Enslin at Michigan State University. All county files were renamed and processed to remove wells that fell outside of the county boundaries. This application uses MapObjects Lite code to process the spatial analyzes and the field calculations. Framework V4b county boundaries were used to clip out bad point locations and the MDNR public land survey section shape file was used to flag points that were outside of there survey sections. Other attributes were added such as elevation information, rock and drift well types, and drift aquifer percentages. Next all counties and associated lithology information were merged into a single statewide shape file.
