context_page_description: Chalakudy River or Chalakudy Puzha is the fifth longest river in Kerala, India. The river flows through Palakkad district, Thrissur District and Ernakulam District of Kerala. The total drainage area of the river is 1704 km². out of this 1404 km² lies in Kerala and the rest 300 km² in Tamil Nadu. The length of the river is 145.5 km. Though Chalakudy river in strict geological sense is a tributary of the Periyar river, for all practical purposes it is treated as a separate river by Government and other agencies. The River has gained its name, since it flows along the banks of the Chalakudy Town, the major settlement along the course of the river. It is perhaps the most unpolluted and pristine river in the state and even in India due the limited amount of industries and wastage disposal around it. Chalakudy River and its basin area were one of the most affected rivers during the 2018 Kerala floods.
