Water Quality Monitoring Data

The Iowa Environmental Council has compiled water quality monitoring data sources as a resource for Iowans who would like to know more about our lakes and streams.

We believe that water quality projects supported by taxpayers should provide regular reporting with standardized, easily accessible, user-friendly data. Iowans should understand if their tax dollars are resulting in cleaner water. Support for water monitoring on both the large and small watershed scale is critical to guiding implementation of the Nutrient Reduction Strategy.

Iowa Department of Natural Resources Information

The Iowa Department of Natural Resources (DNR) maintains a network of “fixed” stations to monitor ambient water quality data in Iowa. Currently, 60 stream sites are sampled monthly. The state program also includes monitoring of groundwater, public lakes, and selected wetlands.

University of Iowa IIHR – Hydroscience & Engineering Information
