Question

Details about the structure and functioning system of mettur dam and it's storage capacity during different monsoons

Answer 1

Situated in Tamil Nadu, Mettur Dam is among the largest dams of India. It is located across river Kaveri also known as 'Dakshin Ganga'.

Built in 1934, the dam takes a maximum height of 214 ft and width of 171 ft. The length of the dam is 5600 ft and it is also known as Stanley Reservoir. Upstream from the dam is Hoggenakkal Falls. The maximum level of the dam is 120 ft. Also the maximum capacity of the dam is 93.4 billion cubic ft, which is nearly twice that of its Karnataka counterpart of Krishna Raja Sagar dam.

Due to a number of dams constructed across Kaveri river and its tributaries in Karnataka, Mettur Dam doesn't receive much water in lean seasons. As a result, the dam nearly goes dry during certain periods of the year, often when water is most needed by the farmers and the general public of Tamil Nadu.
