Mettur Dam

The Mettur Dam is one of the largest dams in India and also the largest in Tamil Nadu, located across the river Cauvery where it enters the plains. Built in 1934, it took 9 years to complete.[1] Maximum height and width of the dam are 214 and 171 feet respectively. The dam receives inflows from its own catchment area, Kabini Dam and Krishna Raja Sagara Dams located in Karnataka. There is a park at the base of the dam called Ellis Park maintained by the Tamil Nadu Public Works Department. It provides irrigation and drinking water facilities for more than 12 districts of Tamilnadu and hence is revered as the life and livelihood-giving asset of Tamil Nadu

History

The funds were provided from the taxes collected in the Madras Presidency. The Board of Revenue was headed by Sir C.P. Ramaswamy Iyer who initiated the building of the dam. As a result the dam authorities evacuated the people of Nayambadi and some other villages where the dam was sited. When the water level of the reservoir recedes, even now old Christian Church of Nayamabadi and some Hindu temples from other villages emerge from it as proof. Those people who migrated from Nayambadi have settled down in Martalli, Cowdalli and other nearby villages in the Kollegal taluk of Chamarajanagar district of the state of Karnataka. Among those who relocated were the paternal grandfather and father of Veerappan who settled at the foot of MM Hills.

Capacity
River Cauvery crossing Mettur Dam

The total length of the dam is 1,700 metres (5,600 ft). The dam creates Stanley Reservoir. The Mettur Hydro Electrical power project is also quite large. The dam, the park, the major hydroelectric power stations, and hills on all sides make Mettur a tourist attraction. Upstream from the dam is Hogenakkal Falls. The maximum level of the dam is 120 ft (37 m) and the maximum capacity is 93.47 tmc ft. Area of reservoir 42.5 square kilometer.

Its capacity of 93.4 billion cubic feet (2.64 km3) is nearly twice that of its Karnataka counterpart of KRS; It was built in-line with KRS Dam, which was designed by Sir M Vishveswariah[2] in 1911 and completed in 1917 near Mysore.

Water dispute
Main article: Kaveri River water dispute

The Mettur Dam has received public attention since the latter half of the 20th century, and especially in the mid-1990s, due to the Kaveri River water dispute between the States of Tamil Nadu and Karnataka.[3] Because of subsequent dams constructed across the Cauvery and its tributaries in Karnataka, namely Harangi Dam, Hemavathi Dam, Kabini Dam, following the KRS Dam; Mettur Dam does not receive much water during 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. This has created serious dispute and tension between the neighbouring states of Karnataka and Tamil Nadu. Governments of the respective states, the Supreme Court, and the Cauvery Tribunal have so far not been successful in resolving the dispute. The tribunal has specified an annual release of 192 tmcft by Karnataka to Tamilnadu. In the years of deficit in realisation the dispute aggravates in both the states. The major reasons for the deficit are inadequate realisation of Southwest monsoon in the primary catchment areas of the river viz., Kodagu and Wayanad and the over reliance of the river water for irrigation and drinking water schemes in both the states.
