Water quality in the Upper Mississippi River System is important in determining habitat quality and ecosystem function. According to the NWQS for Malaysian rivers, temperature, pH, conductivity, TDS, SO 4, and TH were classified as class I, while DO, turbidity, and BOD were categorized under class II, Therefore, these parameters were in the normal range.
