The Mandovi or Mahadayi, formerly known as the Rio de Goa, is a river described as the lifeline of the Indian state of Goa. The Mandovi and the Zuari are the two principal rivers in the state of Goa. The Mandovi joins with the Zuari at a common creek at Cabo Aguada, forming the Mormugao harbour. Panaji, the state capital and Old Goa, the former capital of Goa, are both situated on the left bank of the Mandovi.

Goa is an Indian state located in North India within the Konkan region, geographically separated from the Deccan highlands by the Western Ghats. It is bound by the Indian states of Maharashtra to the north, and Karnataka to the east and south, with the Arabian Sea in the west. It is India's smallest state by area and fourth-smallest by population. Goa has the highest GDP per capita among all Indian states, two and a half times as high as the GDP per capita of the country as a whole. The Eleventh Finance Commission of India named Goa the best-placed state because of its infrastructure, and India's National Commission on Population rated it as having the best quality of life in India. It is the second-highest ranking among Indian states in the human development index.
