Abstract

Physico-chemical and coli form counts have been studied in the Yellemallappa Chetty Lake during summer season (February 2004 to June 2004) to evaluate lake water quality for Fish culture, Irrigation and for Recreational purposes. The three different locations were selected for variation studies, namely (i). Inlets of the lake (ii). Within the lake and (iii). Outlets of the lake, and a total of 18 parameters were studied in all the three locations. Based on the Carlson's status indices the lake was classified as eutrophic during the study period. Other parameters were in normal range but show drastic changes from month to month and location to location.
