Rivers and Lakes: Flowing Through Landscapes, History, and Everyday Life
Kerala is blessed with an extraordinary network of rivers and lakes that shape its geography, ecology, agriculture, and culture. Flowing from the Western Ghats to the Arabian Sea, these water bodies nourish forests, farmlands, wetlands, and backwaters. Rivers serve as natural transport routes, support irrigation, and sustain diverse ecosystems, while lakes form scenic tourism zones and vital fishing grounds. Together, they create Kerala’s signature landscapes of lush greenery and interconnected waterways.

Natural Role of Rivers
Kerala has more than 40 west-flowing rivers, most originating in the Western Ghats. These rivers are relatively short but fast-flowing, carrying fresh mountain water to coastal plains, backwaters, and estuaries. They replenish groundwater, support rice cultivation, and maintain wetlands that protect against floods and saltwater intrusion.
