River Mandovi, also known as Mahadayi or Mhadei river is regarded as the lifeline of Goa. The river originates from a cluster of 30 springs at Bhimgad in the Western Ghats in the Belagavi district of Karnataka and has a total 2,032 km2 catchment area of which 1,580 km2, 375 km2 and 77 km2 catchment area are in Goa, Karnataka and Maharashtra respectively. Owing to the differences over the sharing of the river water among the states of Goa, Karnataka and Maharashtra, the union government has constituted Mahadayi Water Disputes Tribunal to examine the claims made by the states.
