Turkey River IA 01-TRK-148

Assessment Comments

Assessment is based on IDNR monthly WQ monitoring station south of Garber at USGS gauge.

Basis for Assessment

SUMMARY:  The Class B(WW) aquatic life uses remain assessed as "fully supporting / threatened."  Fish consumption uses remain "not assessed."  EXPLANATION:  Continue to use the assessment of the Class B(WW) uses developed for the 1998 report (above).   This assessment was based on results of water quality monitoring during the 1996-1997 biennial period at the DNR quarterly monitoring station near Garber.   Results from stations monitored monthly or more frequently, however, are preferred for Section 305(b) assessments in order to improve the accuracy and confidence level of the assessment.   As part of DNR's expanded water quality monitoring program, monthly monitoring at the Garber station began in October 1999.   Fish consumption uses remain "not assessed" due to the lack of fish tissue monitoring in this river reach.
