Explanation
The Mettur Dam is one of the largest and most significant multipurpose river valley projects in South India. It is constructed across the Cauvery River and serves as a primary source of irrigation and drinking water for the delta region of Tamil Nadu.
Detailed Analysis

- Reservoir: The reservoir formed by the Mettur Dam is known as the Stanley Reservoir. It is one of the largest fishing reservoirs in South India.
- Historical Context: Constructed in 1934, the dam plays a pivotal role in the agricultural economy of the Cauvery Delta region.
- Relevance to Water Disputes: Being the first major storage structure for the Cauvery water in Tamil Nadu after the river leaves Karnataka, the water levels at Mettur are a key indicator in the Cauvery Water Dispute between Tamil Nadu and Karnataka. The release of water from Karnataka’s reservoirs (like Krishnarajasagara) directly impacts the inflow into Mettur.

Mettur Dam is located in Tamil Nadu (Salem District) across the Cauvery River, creating the Stanley Reservoir.
