The Kaveri (earlier known as Ponni, the golden maid, because of the fine golden silt deposits) flows through Karnataka and Tamil Nadu. The river originates at Talakaveri in the Brahmagiri Range in the Western Ghats, of Karnataka’s Kodagu district,1,341 m above sea level, and flows in a south-easterly direction for about 800 km before emptying into the Bay of Bengal. It reaches the sea in Poompuhar in Mayiladuthurai district. This is Tamil Nadu’s largest river, dividing the state into north and south.
