Abstract
The kolleru lake in the south-eastern Indian state of Andhra Pradesh is the largest freshwater lake of the country. It is a shallow freshwater wetland and a natural depression situated between 81°05’E-81’20’E longitude and 16°32’N-16°51’N latitude. And it is believed to have been formed around 6000 years BP (Reddy P.R. 2014), which is remained for thousands of years since its formation, despite of encroachment, sedimentation through inland streams, weed infestation and reduction in the flushing capacity of Upputeru due to the over extension of its course by progressive advancement of the coastline far away into the sea. In spite of effort to rejuvenate and safeguard the lake region environmental pressures have raised over time. This lake has remarkable significance from socio-economic point of view and sustenance of biodiversity, which need to be protected from various man-made degradation.
