Sole Source Aquifer Maps

On this page:

Optimized Maps - The files that contain the Sole Source Aquifer maps are very large. We have optimized the maps to reduce their file sizes and decrease the download time. Some of these maps are still extremely large and may take a very long time to download. We recommend that you only download them over a high speed Internet connection.
Zip Files - We have also included the maps in their original format for printing. These files are extremely large and had to be compressed into a smaller file called a zip file. You will need an unzip program to unzip the files. Newer computers often come with an unzip program pre-installed. If your computer has an unzip program, it should launch automatically when you click on one of the files below. If your computer does not have an unzip program installed, you will need to install one. You can find a number of free downloadable unzip programs on the Internet.
