Industrial activities, urban and agricultural activities are major sources of pollution of lakes (Iscen et al., 2008). Contamination of water with microorganisms and harmful pollutants has created health problems, such water quality with respect to human health and ecological interrelationship is an aspect of limnology (Krishna et al., 2009).
