Vani Vilasa Sagara
Vani Vilasa Sagara or Mari Kanive is a dam in Hiriyur Taluk, Chitradurga District in Karnataka. It is located about 20km south-westerly to Hiriyur, 32km north-easterly to Hosadurga, 58km south-easterly to Holalkere, 50km northerly to Huliyar, 60 km southerly to Chitradurga, and 180km north-westerly to Bangalore.
Vani Vilasa Sagara was built by the Mysore Maharajas pre-independence across the river Vedavathi. Vani Vilasa Sagara is the oldest dam in the state. The dam is an exquisite piece of architecture, an engineering marvel for that time. The dam irrigates a large area of the Deccan region of Central Karnataka, which is otherwise largely a dry land. It irrigates more than 100 km² of land in Hiriyur and Challakere taluks through right and left bank canals. Vani Vilasa Sagara dam is also the source of domestic water for Hiriyur and Chitradurga.
