There are nine most important rivers in Goa flowing from East (Western Ghat) to West (Arabian Sea) except for Sal River.
Terekhol, Chapora, Baga, Mandovi, Zuari, Sal, Saleri, Talpona, Galgibag are the major nine rivers of Goa.

Among these rivers Mandovi and Zuari drain 2553 Sq. Km, about 70% of the total geographical area of Goa. Out of nine rivers, six originate and flow entirely inside the state boundaries and do not have any interstate implications. However, river Terekhol and Chapora originate in Maharashtra state while Mandovi originates in Karnataka.

These rivers form an integral part of Goan life because of their portability, irrigation facilities, agriculture and coastal resources, transportation of mining ores, etc.

The Mandovi flows through Cumbarjua, Divadi and Chodné, eventually pouring into the Arabian Sea.
