## **The Reservoir Created By Tungabhadra Dam Is** ### **An In-Depth Look at an Engineering Marvel** The Tungabhadra Dam, located on the Tungabhadra River in Karnataka, India, is a remarkable engineering feat that has played a pivotal role in the socio-economic development of the region. Completed in 1956, the dam and its associated reservoir have transformed the landscape, providing irrigation, flood control, hydroelectricity, and drinking water to millions of people. The Tungabhadra Reservoir, formed by the dam, is one of the largest in India with a capacity of 135.40 TMC (thousand million cubic feet). The reservoir stretches for a length of 200 kilometers and covers an area of 375 square kilometers. It provides irrigation to approximately 3.2 million acres of land in the districts of Raichur, Koppal, Bellary, and Bijapur. The dam's irrigation system has brought about a green revolution in the region, transforming arid lands into fertile agricultural fields. The dam also plays a crucial role in flood control, protecting downstream areas from the vagaries of the Tungabhadra River, which is prone to flash floods during the monsoon season. The reservoir acts as a natural buffer, holding excess water and releasing it gradually, preventing catastrophic flooding. ## **Hydroelectricity and Drinking Water** In addition to irrigation and flood control, the Tungabhadra Dam also generates hydroelectricity. The powerhouse at the base of the dam has an installed capacity of 80 MW, providing a significant source of renewable energy to the region. The reservoir also serves as a vital drinking water source for nearby cities and towns. The Tungabhadra Water Supply Scheme supplies drinking water to Bellary, Raichur, and surrounding areas, meeting the daily needs of over 2 million people. ## **Socio-Economic Impact** The Tungabhadra Dam has had a profound socio-economic impact on the region. The increased agricultural production has led to improved incomes and livelihoods for farmers, while the industrial development spurred by the availability of hydroelectricity has created new employment opportunities. The dam has also contributed to improved public health by providing access to clean drinking water, reducing waterborne diseases. ## **Environmental Considerations** While the Tungabhadra Dam has brought numerous benefits, it has also had some environmental impacts. The construction of the dam led to the displacement of thousands of people and the submergence of forests and wildlife habitats. The reservoir has also been affected by sedimentation, reducing its storage capacity and affecting fish populations. ## **Conclusion** The Tungabhadra Dam is a testament to human ingenuity and its ability to harness natural resources for the benefit of society. It is a multi-purpose project that provides a range of essential services, including irrigation, flood control, hydroelectricity, and drinking water. Despite some environmental challenges, the dam has played a vital role in the socio-economic development of the region and continues to be an invaluable asset to the people of Karnataka.
