Documentation
Assessment Comments
Monitored in 1990 by ISU as part of the Clean Lakes Classification Study and used results of August 1994 fish tissue monitoring.
Basis for Assessment
Used assessments of support of the Class A primary contact recreation uses (=FST), Class B(LW) aquatic life uses (=FST), and fish consumption uses (=FS) developed for the 1994 and 1996 reports. Assessments were reviewed by the DNR Fisheries Bureau in 1998. DNR Fisheries suggested that primary threats to full support of designated uses were nutrients and organic enrichment from natural shallowness.
