Harangi Dam - Coorg

The Harangi Dam, located in the Kodagu district of Karnataka, is a magnificent structure that serves multiple purposes for the region. Built across the Harangi River, a tributary of the Kaveri River, this dam has been instrumental in providing water for irrigation, generating hydroelectric power, and controlling floods in the area. With its impressive engineering and strategic location, the Harangi Dam has become a lifeline for the people of Karnataka.

 

The Construction of Harangi Dam

The construction of the Harangi Dam began in 1971 and was completed in 1979. The dam was built by the Karnataka State Government with the primary objective of harnessing the water resources of the Harangi River. The project was executed by the Karnataka Power Corporation Limited (KPCL) and the Central Water Commission (CWC). The dam stands at a height of 47 meters and has a length of 846 meters. It has a storage capacity of 8.56 thousand million cubic feet (TMC) and a catchment area of 717 square kilometers.

 

Water for Irrigation

One of the main purposes of the Harangi Dam is to provide water for irrigation in the region. The dam has a canal system that distributes water to the agricultural lands of the surrounding areas. The water from the dam is used for cultivating various crops, including paddy, coffee, and spices. The availability of water for irrigation has significantly improved the agricultural productivity of the region, benefiting the farmers and the economy as a whole.

 

Hydroelectric Power Generation at Harangi Dam

The Harangi Dam also plays a crucial role in generating hydroelectric power. The dam has a power station with an installed capacity of 9.5 megawatts (MW). The water released from the dam flows through the penstocks, which are large pipes that carry the water to the turbines. The force of the flowing water rotates the turbines, which in turn generate electricity. The generated power is then supplied to the grid and used to meet the energy needs of the surrounding areas.

 

Flood Control

In addition to irrigation and power generation, the Harangi Dam serves as a flood control mechanism. The dam has a spillway that allows excess water to flow out during heavy rainfall or monsoon seasons. By regulating the water flow, the dam helps in preventing floods downstream. The controlled release of water ensures that the river does not overflow its banks and cause damage to the surrounding areas. The dam has been successful in mitigating the impact of floods and protecting the lives and properties of the people living in the downstream regions.

 

Tourism and Recreation at Harangi Dam

Apart from its functional aspects, the Harangi Dam has also become a popular tourist attraction in Karnataka. The scenic beauty of the dam and its surroundings attract visitors from far and wide. The calm and serene environment, coupled with the lush greenery, makes it an ideal spot for picnics and leisure activities. Boating facilities are also available at the dam, allowing visitors to enjoy a peaceful ride on the reservoir. The Harangi Dam has become a favorite destination for nature lovers and photography enthusiasts.

 

Environmental Impact

While the Harangi Dam has brought numerous benefits to the region, it has also had some environmental impact. The construction of the dam resulted in the submergence of a large area of land, leading to the displacement of several families. The dam has also altered the natural flow of the river, affecting the aquatic ecosystem. However, efforts have been made to mitigate these impacts through various measures, including the implementation of fish ladders to facilitate the movement of fish and other aquatic organisms.

 

Conclusion

The Harangi Dam stands as a testament to human ingenuity and engineering prowess. It has transformed the lives of the people in Karnataka by providing water for irrigation, generating hydroelectric power, and controlling floods. The dam has also become a popular tourist spot, attracting visitors with its scenic beauty. While it has had some environmental impact, steps have been taken to minimize the negative effects. The Harangi Dam continues to be a vital lifeline for the region, ensuring the prosperity and well-being of the people of Karnataka.
