The Mithi River (Pronunciation: [miʈʰiː]) is a river on Salsette Island, the island of the city of Mumbai, India. It is a confluence of tail-water discharges of the Powai and Vihar lakes. The river is seasonal and rises during the monsoons. The overflowing lakes also contribute to the river flow, which is stopped by a dam at other times. During this season, the gutter is a favourite with anglers, who can catch large fish that have escaped from the lakes. Chattrapati Shivaji Maharaj International Airport is located right next to the section of river at Andheri (E).
