North Fork Maquoketa River IA 01-NMQ-88
mouth (Jackson Co.) to confluence with Lytle Cr. S8 T85N R2E Jackson Co.
Assessment Comments
Assessment is based on results of IDNR/UHL monthly fixed monitoring station near Maquoketa from 2002-04.
Basis for Assessment
SUMMARY: The Class B(WW) aquatic life uses are assessed (monitored) as "fully supporting." The fish consumption uses remain "not assessed" due to the lack of fish contaminant monitoring in this river reach. This assessment is based on results of IDNR ambient monthly monitoring near Maquoketa (station 10490001; formerly station 290120) from January 2002 through December 2004.
EXPLANATION: Results of monthly ambient water quality monitoring at the DNR station near Maquoketa show no violations of Class B(WW) water quality criteria for pH, dissolved oxygen, or ammonia-nitrogen in the approximately 36 samples analyzed for conventional pollutants or in the approximately 10 samples analyzed for toxic metals and pesticides during the 2002-2004 period. These results suggest "full support" of the Class B(WW) aquatic life uses.
The fish consumption uses are "not assessed" due to lack of fish contaminant monitoring in this river reach.
