Decade-low water levels at Linganamakki Reservoir threaten power generation

Linganamakki Reservoir, a key source of electricity for Karnataka, is facing a severe water shortage due to a prolonged lack of rainfall. According to sources at the Karnataka Power Corporation Ltd (KPCL), the current water storage levels are critically low, and power generation can only be sustained for the next 20 days.

Narayana Gajakosh, Chief Engineer at KPCL said that the reservoir currently holds 1740.35 feet of water, which is significantly below its maximum capacity of 1819 feet from sea level. The water level on the same day last year was recorded to be 1654.64 feet.

It is evident that the reservoir is experiencing an alarming decline in water storage, the likes of which have not been witnessed in a decade, he said.

About 1,356 cusecs of water is being released through the reservoir’s sluice gate. This water is primarily used for electricity generation at the hydroelectric power plants. About 4 million units of electricity is being produced at the Sharavati hydroelectric plant, while Mahatma Gandhi and Gerusoppa hydroelectric dams each contribute 1 million units, he said.

There remains a glimmer of hope for power generation if the region experiences extensive rainfall in the Kargal and Hosanagar areas of the Sharavati basin. The KPCL anticipates that an increase in water flow to the reservoir from these regions could replenish the dwindling water levels. The revival of rains in the highlands is the only silver lining for avoiding a potential halt in electricity production.
