Assessment Comments

Assessment is based on results from DNR monthly monitoring station near Elkport, Clayton County.

Basis for Assessment

Levels of FC bacteria in 3 of 6 non-runoff samples exceeded the Class A WQC.   Data are too few to meet completeness criteria; thus, even with 50% violation, assess as PS.
