Goa is located along the Mandovi River, which is one of the principal rivers flowing through the state. The Mandovi River is crucial to Goa's geography, economy, and transportation, with Panaji (the state capital) situated on its banks. The Ganga flows through North India, Gomati is a tributary of the Ganges in Uttar Pradesh, and the Sabarmati flows through Gujarat - none of these are in Goa.
