Water Well Coverages and Data (Updated 10/2003)
The Division of Water is in the process of creating Arc/Info coverages of all of the water well location maps for the state of Ohio. The source maps consist of approximately 300,000 water well locations that have been plotted on topographic quadrangles. A large scale effort to add well specific attribute data to these coverages is currently underway. This project will entail linking the existing well log database with the digitized location data. Data will be entered on a county by county basis. No completion date has not been set for this phase of the project.

Ground Water Resource Coverages
The Division of Water has completed the mapping of ground water resources for every county in Ohio. Although all of the ground water resource maps have been created, only a portion of them have been converted to a digital Arc/Info format. These coverages were created on a county basis and are in various stages of completion.
NOTE: Coverages available for download may be found by searching the ODNR GIS central archives. Links to download coverages are provided within the metadata reports that are returned as the result of archive queries.

Ground Water Pollution Potential Coverages (Updated 10/2003)
The Division of Water has created pollution potential maps for approximately 64 of the 88 Ohio counties. Some of these maps have also been converted to digital Arc/Info format. These coverages were created on a county basis and are in various stages of completion.
NOTE: Coverages available for download may be found by searching the ODNR GIS central archives. Links to download coverages are provided within the metadata reports that are returned as the result of archive queries.

Ground Water Potentiometric Surface Maps Shape Files (Updated 07/20/2005)
Ohio?s potentiometric surface mapping program began in the late 1990's under the direction of the Ohio Department of Natural Resources, Division of Water. This program was initiated by the Ohio EPA for use in their Source Water Assessment Program.
Potentiometric surface maps indicate the elevation and horizontal direction of ground water flow. Potentiometric surface maps are being created for bedrock (consolidated formations) and sand & gravel (unconsolidated formations) aquifers.
NOTE: Shape files available for download may be found by searching the ODNR GIS central archives. Links to download shape files are provided within the metadata reports that are returned as the result of archive queries.

State Wide Aquifer Map (Updated 12/2000)
( Go to main page of this item now)
In March 2000 the Division of Water completed a series of aquifer maps that cover the entire state of Ohio. Separate maps were constructed for the bedrock and unconsolidated aquifers. All maps were prepared at a scale of 1:24,000 (1 inch equals 2000 feet), digitized into the GIS program ArcInfo, and then joined into statewide aquifer coverages. These coverages contain information on aquifer yield, thickness, boundaries and names. Coverages are available in ArcInfo (.e00) export format or ArcView shapefile (.shp) format.
Floodplain Management GIS (Updated 01/2006)
The Division of Water is currently using a GIS interface to incorporate the various data sources associated with floodplain management. This GIS application provides an organized, comprehensive method of obtaining floodplain information in an Arcview environment. Future goals associated with this project focus on using the available information to enhance the level of floodplain management provided by the Division of Water.

Dam Inventory Coverages
The Division of Water has created an Arc/Info coverage of the inventory of regulated dams in Ohio. This coverage contains an enormous amount of data and is currently being manipulated to provide an organized presentation of the information.
