Mullaperiyar Dam Dispute

Mullaperiyar is over-a-century-old dam located river Periyar along the Periyar Tiger Reserve. The major rivers through the reserve are the Mullayar, Periyar, Pamba and Azhutha Rivers.

The dam, located in Idukki district of Kerala, was built with the intention of diverting the West-flowing Periyar river eastwards to the arid rain shadow region of Madurai (Tamil Nadu).

Kerala and Tamil Nadu are in a constant tussle regarding the strength of the dam and hence the level of water that should be maintained in the dam.

Like many dams in India, the Mullaperiyar is located in one state (Kerala), but operated by another (Tamil Nadu). Mullaperiyar dam is located in Kerala and is owned by Tamil Nadu.

The Periyar river is the longest but the second largest river of Kerala. It flows into the Arabian Sea.It is one of the few perennial rivers in the region.
