Assessment Comments
Basis for Assessment
Continued to use the assessment of the Class B(LW) aquatic life uses developed for the 1994 and 1996 reports (=FST). Due to changes in assessment methodology for Iowa Section 305(b) reports, changed the assessment from FST to FS due to absence of a declining WQ trend. Continued to assess support of Class A primary contact recreation as FS as in the 1996 report.
