Cedar Creek IA 04-LDM-1053
mouth (S33 T75N R17W Mahaska Co.) to confluence with North Cedar Cr. in S15 T74N R18W Marion Co.
Assessment Comments
Assessment is based on results of IDNR ambient monthly monitoring near Bussey.
Basis for Assessment
Continue to assess support of the Class B(WW) aquatic life uses as FST. Fish consumption uses remain "not assessed." EXPLANATION: The assessment of the Class B(WW) uses is based on results of the two years of DNR quarterly monitoring (1996-1997) on the near Bussey (see assessment for the 1998 report). Results from the DNR stream use assessment conducted in June 1992 are older than five years and are thus considered too old for characterizing current water quality conditions. This assessment was based on results of quarterly monitoring. 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 Cedar Creek station began in October 1999. Fish consumption uses were not assessed due to lack of fish tissue monitoring in this river reach.
