Bhawanipatna: Indravati Hydroelectric Project, also known as the lifeline of Kalahandi district, is witnessing a significant decline in its water-holding capacity, thanks to sediment accumulation due to inadequate desiltation drives. The hydel project has long been a boon for the residents of Kalahandi district, supplying water for both kharif and rabi crops cultivation while also generating electricity for the surrounding region.
However, years of inadequate silt removal in the reservoir have led to sediment accumulation, reducing the reservoir’s water-holding capacity. This decline in water level has raised concern over potential disruptions to power generation and irrigation. Sources said works for Indravati Hydroelectric Project started in 1978 and the project became fully functional by 2001. It features four turbines capable of generating 600-megawatt electricity. Its left and right main canals, and a lift irrigation system provide water to 1,28,012 hectares of farmland across eight blocks in Kalahandi. This transformation has turned arid lands into fertile fields, strengthening the backbone of local farmers. Additionally, the 600-megawatt power generation plays a crucial role in meeting the state’s energy needs.
However, the project now faces a crisis. While the reservoir’s maximum water level stands at 642 metres and the minimum at 625 metres, the levels have steadily declined over the years. Farmers in the district are becoming increasingly concerned, while officials continue to attribute it solely to fluctuating rainfall, deflecting their responsibilities for structural shortcomings. Without timely and permanent solutions, the project, which has been instrumental in Kalahandi’s agricultural and economic growth, may face an existential threat.

On the other hand, due to deforestation at the upper reaches of the reservoir and lack of necessary protective barriers, silt, mud, soil, and rocks flow into the reservoir along with rainwater every year. Instead of going for a permanent solution, authorities are wasting a huge sum of money on silt removal. According to sources, between 2022 and 2024, Rs 24 crore was spent on silt removal in only a few metres of the reservoir. Given that the reservoir has a water storage capacity of 2,300 cubic metre and covers an area of 2,639 sq km, it is difficult to estimate how much silt has accumulated. Currently, irrigation for rabi crops is being carried out in limited areas through the left and right canals, requiring 65 cubic metre water per day. Meanwhile, 195 to 210 megawatt electricity is being generated daily.
However, no one has provided an answer as to when the Water Resources department will identify the causes of declining water levels or when a protective barrier will be built to prevent silt accumulation. When contacted, chief engineer, Construction, Jagannath Pani of Upper Indravati Project at Mukhiguda stated that authorities are deeply concerned over the issue, and efforts are on to take appropriate measures.
