Water Quality Assessment and TMDL Information


At this time, EPA is unable to present the Section 305(b) water quality assessment and the 303(d) impaired waters report as one integrated report for Iowa. As more data become available, this may change. For now, information for this state is available in two separate web reports.

Assessed Waters Report contains the state 305(b) water quality assessment data.

Impaired Waters Report contains the state 303(d) impaired waters data.
