Monsoon Surge Triggers Red Alerts and Rising Reservoir Inflows Across Malnad Region

Intense monsoon activity gripped the Malnad region of Karnataka on August 1, 2026, as relentless downpours pushed river systems toward their limits and paralyzed local infrastructure. The India Meteorological Department (IMD) responded to the escalating conditions by issuing a red alert for Shivamogga, Dakshina Kannada, and Chikkamagaluru. Forecasters warned of sustained winds between 40 and 60 km per hour, with precipitation expected to peak at 204.5 mm in high-impact zones.

Rainfall Surpasses Historical Averages

Data recorded in the 24 hours leading to 8:30 a.m. on August 1 reveals that precipitation levels significantly exceeded seasonal norms. Shivamogga district registered an average of 52 mm, more than doubling its typical 24 mm average. Similarly, Chikkamagaluru recorded 45 mm against a standard 19 mm, while Hassan saw 20 mm compared to its usual 8 mm. The highest localized volume was documented at Begar in Sringeri taluk, which recorded a staggering 294.5 mm of rain. Other high-volume areas included Agumbe in Tirthahalli taluk with 279 mm and Hongadahalla in Sakleshpur taluk with 180.5 mm.

Regional Precipitation Breakdown (August 1)

  • Chikkamagaluru District: Sringeri (197 mm), Koppa (130 mm), Kalasa (99 mm), N R Pura (53 mm), Mudigere (49 mm).
  • Shivamogga District: Tirthahalli (98 mm), Hosanagara (80.6 mm), Sagara (52.7 mm), Sorab (48.9 mm), Shikaripur (26.4 mm).

Reservoir Storage and River Management

The surge in precipitation has directly impacted the state's hydraulic infrastructure. The Tunga dam at Gajanur reached near-maximum capacity, holding 3.21 TMC against a limit of 3.24 TMC. To manage the 26,864 cusecs inflow, authorities increased discharge to 27,119 cusecs. Meanwhile, the Linganamakki reservoir on the Sharavati river saw inflows of 38,183 cusecs. Despite the current rise, Linganamakki's storage of 51.32 TMC remains notably lower than the 127.37 TMC recorded during the same timeframe in 2025.

In Hassan, the Hemavathi reservoir storage climbed to 25.98 TMC, while the Bhadra reservoir at Lakkavalli reached 40.41 TMC. The Sharavati river is currently overflowing due to the continuous volume entering its catchment areas. In response to the weather risks, administrators shuttered primary schools and anganwadi centers in Sringeri, Koppa, and the Balehonnur hobli of N.R. Pura taluk.
