Abstract

Abstract:

Kolleru Lake is the largest freshwater lake in India. It is recognized as wetland of international significance and is one of the 27 Ramsar wetlands in India. Designated as a sanctuary in 1999 Kolleru Bird Sanctuary (KBS) provides habitat to diverse flora and fauna including some rare and threatened fauna. Seventy eight fish species belong to fourteen orders, 37 families and 57 genera’s were identified in the Kolluru Lake and Upputeru Creek diversity. Various samples were collected from different areas in and around Kolleru Lake analyzed for their physicochemical characteristics such as pH, total dissolved solids, Dissolved Oxygen, Biological Oxygen Demand, Chemical Oxygen Demand, NO3, PO4 etc.,. The results of this analysis were compared with the water quality standards of BIS. The quality of water samples were discussed with respect to these parameters and thus an attempt was made to ascertain the quality of water in the sampling areas.
