The range of various physico-chemical features, calcu- lated from the three lakes is presented in Table 1. These lakes have been studies from time to time by different lim- nologists with the aim to categorize these lakes according to approved international standards (OECD, 1982; APHA, 1998). The present study showed that all the three lakes have reached to the level of eutrophic condition, but the level of trophic status varies.
