Assessment Comments

No water quality monitoring conducted and/or data is greater than 5 years old.

Basis for Assessment

Changed the assessment of support of the Class B(LR) aquatic life used to "not assessed" due to (1) age of the WQ data from the DNR quarterly monitoring station near Spencer (> 5 years) & (2) lack of any biological monitoring in this reach from either DNR stream use assessments or DNR biocriteria sampling.   The DNR quarterly station will again be monitored during FFYs 1998-99.   Biological monitoring is needed in this reach to provide information necessary for developing an assessment of support of the Class B(LR) uses.
