Karnataka prepares for deeper water and power strain as rain deficit worsens
Bharatmorning.com – Karnataka is stepping up preparations to manage pressure on drinking water supplies and electricity availability after a prolonged monsoon shortfall pushed much of the state into drought-like conditions. Deputy Chief Minister D K Shivakumar said 200 of the state’s 239 taluks have been affected by the weak rainfall pattern, raising concern over crop damage, falling groundwater and rising energy demand.
The government has already declared 101 taluks drought-hit. It plans to assess and classify other affected areas in line with central government norms, as the scale of the rainfall deficit becomes clearer. The challenge extends beyond agriculture: lower rainfall reduces recharge of wells and aquifers, affects reservoir storage and can make it more difficult to meet water needs in towns, villages and cities.
September rainfall gap adds to season-long concern
The state’s rainfall shortage sharpened in September, when Karnataka received only about 10 mm of rain against a normal level of 51 mm. That amounts to an 81% deficit for the month.
Rainfall had remained below normal through the earlier monsoon months as well. June recorded 116 mm compared with a normal 199 mm, leaving a 42% deficit. In July, the state received 192 mm against the usual 271 mm, a shortfall of 29%. August brought 169 mm, below the normal 220 mm.
Such a sustained gap has implications across the state. Farmers face losses when rainfall is insufficient for standing crops, while depleted groundwater can tighten household and municipal supplies. The government’s immediate priority is likely to be balancing these needs while conserving available water for essential use.
Electricity demand crosses 19,000 MW
Power supply is another major concern. Peak demand crossed 19,000 MW last week, forcing Karnataka to purchase electricity at prices of ₹11 to ₹12 per unit. Shivakumar said electricity use had increased, particularly because of greater consumption during night-time hours.
“Total power usage has grown due to increased consumption during night hours,” he said.
While Karnataka’s generation capacity has improved, the state may still need to obtain additional electricity from elsewhere if demand remains high or domestic supply proves inadequate. Such purchases can help avoid disruptions, but they come with an added financial burden because power must be bought at prevailing supply costs.
“Irrespective of which state generates power, it can be supplied to Karnataka. However, this will have a supply cost. A meeting was held recently with energy minister KJ George and officials about the issue,” Shivakumar said.
The situation illustrates how water and energy pressures can overlap. A poor monsoon affects agricultural activity and drinking-water reserves, while changing consumption patterns can drive up electricity demand at the same time. Managing the crisis will require attention to supply levels, affordability and the protection of essential public needs.
Reservoir levels shape Cauvery water debate
Deputy Chief Minister G Parameshwara urged the Cauvery Water Management Authority to reconsider directions on water releases, arguing that Karnataka must first safeguard drinking water as storage levels decline.
He pointed to the condition of key reservoirs in the Cauvery basin. Kabini dam storage was already below 50% of capacity, while Harangi dam had also dropped to around half-full. Krishnaraja Sagar, or KRS, had not reached the expected level and stood at roughly 55% to 60% capacity.
“Today, the storage in Kabini dam is already below 50 per cent, while Harangi dam has also fallen to around half of its capacity. Krishnaraja Sagar dam too has not reached the level we had expected and is around 55 to 60%,” he said.
Parameshwara said Karnataka had released water when supplies were sufficient, but the present conditions had changed the calculation. The government has decided that water should be reserved for drinking needs instead of being used for crops, reflecting the seriousness of the shortage.
“When the situation is like this, how can we release water? The government has already decided that water should not be used for crops and should instead be conserved for drinking purposes,” the minister said.
Focus turns to conservation and contingency planning
For residents, the immediate effect of the rainfall deficit may be seen in closer monitoring of water availability, stronger conservation measures and continued attention to electricity consumption during high-demand periods. For farmers, the drought classification process is significant because it formally identifies areas suffering from adverse weather conditions and extensive crop losses.
Karnataka’s response will depend on how rainfall develops, how reservoir storage changes and whether demand for power continues to rise. State leaders have indicated that additional electricity can be procured if necessary, even though doing so raises costs. On the water front, the administration is placing drinking supplies at the centre of its planning as it confronts one of the state’s broadest rainfall shortfalls of the monsoon season.
