Abstract

Lakes are important aquatic systems as they act as a source of drinking water and a habitat for crustaceans, fish and other organisms. Their hydrobiology is impaired mainly through anthropogenic activities. Hence the present work has been designed to study the hydrobiology of Vandiyur Lake at Madurai. The water samples were collected during premonsoon, monsoon and postmonsoon periods and analysed for physical, chemical and biological parameters using standard methods. Many of the physical and chemical parameters and fecal coliforms were higher during premonsoon period. The Vandiyur Lake water exhibited higher values for many of the parameters during premonsoon.
