The Mettur Dam was constructed in 1934 during British rule. The primary purpose was to harness the waters of the Kaveri River for irrigation, addressing the frequent droughts in the region. Sir M. Visvesvaraya, a renowned engineer, played a key role in designing the dam. Its construction involved relocating several villages and submerging vast tracts of land. The dam has played a crucial role in transforming the agricultural landscape of Tamil Nadu, making it a vital lifeline for farmers. Over the years, it has also become an important source of hydroelectric power, contributing to the state's energy needs. The dam stands as a testament to engineering prowess and its enduring impact on the region's economy and environment.
