Assessment Comments

DNR monthly fixed monitoring station near Maquoketa. Runoff sampling in May and July 1996 by DNR/LTRMP.

Basis for Assessment

SUMMARY:  The Class B(WW) aquatic life uses remain assessed as "fully supporting / threatened."  The fish consumption uses remain "not assessed."  EXPLANATION:  Results of water quality monitoring at the DNR monthly station near Maquoketa show no violations of Class B(WW) water quality criteria for pH, dissolved oxygen, or ammonia-nitrogen in the 24 samples collected during the October 1997-September 1999 biennial period.   In addition, no violations of Class B(WW) chronic water quality criteria occurred in the one sample analyzed for toxic metals during this biennial period.   Thus, continue to assess the aquatic life uses as "fully supported / threatened."  The fish consumption uses are "not assessed" due to lack of recent fish contaminant monitoring in this river reach.
