Korapuzha, also known asElathur River, is a short river of 40 km (25 mi), with a drainage area of 624 km2 (241 sq mi), flowing through theKozhikode district ofKerala state inIndia. It is formed by the confluence of two streams,Akalapuzha Lake, situated in the Kozhikode andPunoor puzha which originate in the mountains ofWayanad district. The Korapuzha empties into theArabian Sea atElathur. The river and its main tributaries become tidal as they near the Arabian Sea. There is heavy boat traffic over the last 25 km (16 mi) of its course. It forms part of the West Coast Inland Navigation System.
This 480-metre bridge is the longest bridge in Kozhikode district. Completed in 1940, it has 13 spans. The surroundings are lush green and very photogenic.
The river for some times formed the northern border of theZamorin's kingdom. The Korapuzha is generally considered as thecordon sanitaire between theNorth Malabar andSouth Malabar in the erstwhileMalabar District.[2] Until the 20th century theNair women ofNorth Malabar crossing the Korapuzha and goingSouth Malabar or marrying a person fromSouth Malabar was considered ataboo and those who violated facedBhrasht (Ostracism) and forfeiture ofcaste.[3] The prohibition in North Malabar and South Malabar began with the rivalry between theKolothunad rulers of North Malabar and theZamorin of South Malabar.[3] At the same time, theKolothunad dynasty maintained good relations with theTravancore-Venad Kingdom and theTulu Kingdom.[1][3]Travancore royal family is a close cousin dynasty of theKolathiris ofNorth Korapuzha.[4][5]
