Overview
The VV Sagar Dam is constructed across Vedavathi river near Marikanive village in Hiriyur Taluk of Chitradurga district during the year 1897 to 1907. The Vedavathi river is a tributary to Krishna river. The main object of VV Sagar Project is to provide irrigation facility in the drought prone areas of Chitradurga district. This Project provides irrigation to 25,000 acres of land by constructing a non-over flow Dam of 43.28 m height (142 ft) above the lowest river bed spanning between hill abutments for a length of 405.50 m (1330 ft). The irrigation is proposed under high level canal taking-off from the main dam on the left bank and, left bank and right bank canals taking – off from Kathrikeyanahalli Anicut constructed 8 kms below the Dam.
The gross storage capacity of the Reservoir formed by the construction of the Dam is 850.30 mcum (30 tmc). The utilisation contemplated under the Project is 148.32 mcum (5.25 tmc).
The Dam has a catchment area of 5374 sq km (2075 sq miles) which includes an intercepted catchment area of 3820 sq km (1475 sq miles). The annual yield expected at the Dam site varies from a minimum of 48 mcum to a maximum of 455 mcum. The main Dam built across the Vedavathi river consists of non-overflow Dam. The surplussing arrangement consists of a waste-weir located at 2.40 km to North of Dam by cutting the saddle. The length of the weir is 143 m (468 ft) and is designed to pass the designed flood discharge of 991 cumecs (35,000 cusecs) under a spillage depth of 1.82 m (6 ft).
