The Varada River originates near Vardamoola in Sagara, Karnataka. It flows through the Western Ghats and enters the central districts of Karnataka (Haveri and Bellary). The river joins the Tungabhadra River at Galaganath. Dandavati is a river that flows through Sorab, India. It originates from a reservoir in Kattinakere. The Kattinakere reservoir’s overflow canal turns into a creek gathering strength on its way to become the river Dandavati. The river flows via Kuppe and joins the Varada River at a place called Bankasana near Anavatti. Varada, in turn, joins Tungabhadra and later Krishna River which finally joins the Bay of Bengal in the East coast of India.
