Kerala backwaters are a chain of brackish lagoons and lakes lying parallel to the Arabian Sea coast (known as the Malabar 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.
Vembanad is the largest of the lakes, covering an area of 2033 km². The lake has a large network of canals that meander through the region of Kuttanad.![]The boat races starts with Champakulam Moolam Boat Race which is held on the Pamba River in the village Champakulam on Moolam day (according to the Malayalam Era M.E) of the Malayalam month Midhunam, the day of the installation of the deity at the Ambalappuzha Sree Krishna Temple. Very interesting stories lie behind the origin of Moolam Boat Race.()
