Assessment Comments

Assessment is based on results of fish tissue (RAFT) monitoring near Cedar Rapids in 1996.

Basis for Assessment

SUMMARY:  Support of neither the Class A (primary contact recreation) uses nor the Class B(WW) aquatic life were assessed due to lack of data.   Fish consumption uses remain assessed as "fully supporting."  EXPLANATION:  The DNR quarterly water quality monitoring station at Cedar Bluff (station 303057), upon which previous assessments of the Class A and Class B(WW) uses have been based, has not been monitored since the 1992-93 biennial period.   These data are now considered too old (greater than five years) for developing a valid assessment of support of the Class A and Class B(WW) uses.   As part of DNR's expanded water quality monitoring program, monthly monitoring at the Cedar Bluff station began in October 1999.   Results from this monitoring will allow development of an updated assessment for the 2002 report.   Based on results of the EPA/DNR fish tissue (RAFT) monitoring near Cedar Rapids in 1996, the fish consumption uses remain assessed as "fully supporting" (see assessment for the 1998 report).
