Kerala India

The Kerala backwaters are a chain of brackish lagoons and lakes lying parallel to the Arabian Sea coast of Kerala State in Southern India. The network includes five large lakes linked by canals, both man made and natural, fed by 38 rivers, and extending virtually half the length of Kerala state. The backwaters were formed by the action of waves and shore currents creating low barrier islands across the mouths of the many rivers flowing down from the Western Ghats range.


It is a labyrinthine system formed by more than 900 km of waterways, and sometimes compared to the American Bayou.

The backwaters have a unique ecosystem - freshwater from the rivers meets the seawater from the Arabian Sea. In certain areas, such as the Vembanad Kayal, where a barrage has been built near Kumarakom, salt water from the sea is prevented from entering the deep inside, keeping the fresh water intact. Such fresh water is extensively used for irrigation purposes.

Vembanad Kayal is the largest of the lakes, covering an area of 200 km², and bordered by Alappuzha (Alleppey), Kottayam, and Ernakulam districts. The port of Kochi (Cochin) is located at the lake's outlet to the Arabian Sea. Alleppey, "Venice of the East", has a large network of canals that meander through the town. Vembanad is India’s longest lake.
