Water Monitoring Atlas

The Iowa Department of Natural Resources (DNR) has many maps and applications available to assist the public in finding information about water quality in their area. Data is also available for review and download within these applications as well.

Previously, the DNR had a "water monitoring atlas" available, but newer applications have replaced a lot of the functionality of that atlas, and provide more information about each individual program.
