The Iowa Department of Natural Resources has released its list of impaired waters

Waterloo, IA – According to the state officials, there are more than 700 state lakes, rivers, reservoirs, or wetlands on the list.

The Iowa Department of Natural Resources Water Quality Monitoring and Assessment Section compiles this impaired water list.

The list is composed of those lakes, wetlands, streams, rivers, and portions of rivers that do not meet all state water quality standards.

These are considered impaired waterbodies and states are required to calculate total maximum daily loads for pollutants causing impairments.

This database contains a site location map and a water quality assessment for each individual impaired segment.

The database also provides summary information for the draft 2022 list of impaired waters and Integrated Report.
