About Sasthamkotta Lake
Sasthamkotta Lake, located in Kollam district of Kerala, is the largest freshwater lake in the state. It is a vital source of drinking water, irrigation, and fisheries, supporting thousands of people in the region. Known for its scenic beauty, lush surroundings, and ecological importance, Sasthamkotta Lake is also a cultural landmark, surrounded by temples and villages that reflect the traditional lifestyle of Kerala’s hinterland.
Geography and Location
The lake is situated approximately 25 kilometers from Kollam town, nestled amidst gentle hills and dense vegetation. Covering an area of about 3.73 square kilometers, Sasthamkotta Lake is a freshwater body without direct connection to the sea.

The lake is fed by several small streams and rainfall runoff from the surrounding hills, while its natural drainage maintains the water level throughout the year.

Aquatic life, including various freshwater fish species that sustain local fisheries.
Birdlife, such as herons, kingfishers, and migratory waterfowl, making it an ideal spot for birdwatchers.
Riparian vegetation, which stabilizes the banks and provides a natural habitat for amphibians and small mammals.
The lake’s clear and unpolluted waters distinguish it from many other lakes in Kerala, and it plays a crucial role in maintaining the region’s groundwater table.
