Abstract: Present study has been carried out seasonally in Upper Lake, Bhopal during the tenure of 2015. To evaluate the present scenario of water quality a total of 14 parameters have been analyzed. On scrutinization, majority of water parameters are at the verge of optimum level or do not fall with the range of maximum allowable concentration given by BIS, likewise few of the parameters remain below normal values. Hence, it is inferred that the Lake represents deteriorated and stressful condition caused by anthropogenic and organic pollution. The heavy load of pollution is evident from different sites when compared with standard reference table. Among the most affected sites which approaches anorexia conditions includes “S6” (GMC) 5.2 mg/l during winter and “S6” (GMC) 5.3 mg/l in monsoon season. The range of pH varies from 7.5 -9.3 during winter and summer respectively. Although, most of aquatic organisms thrive well in pH ranging from 6.5-9, beyond these set of limits sensitive organisms begins to respond by either migrating from localized area or they will be replaced by more tolerant species. Hence, Upper Lake represents moderately disturbed state of ecological status for various flora and fauna.
