Karnataka’s major reservoirs have received a significant boost from continued rainfall across the state, with strong inflows being recorded in the Cauvery, Krishna and Malnad catchment areas. According to the latest data released by the Karnataka State Natural Disaster Monitoring Centre (KSNDMC) for August 4, 2026, the state’s 14 major reservoirs collectively added around 34.8 TMC of water in just one day.
The sharp rise in inflows has improved the water situation across several parts of Karnataka, providing relief for drinking-water requirements as well as agricultural activities. Farmers and communities living along river basins are also closely monitoring the rising reservoir levels as several dams approach their storage limits.
Krishna Basin Records the Highest Inflow
Among Karnataka’s major river basins, the Krishna basin recorded the strongest inflow on August 4. Reservoirs in this basin received approximately 22.7 TMC of water during the day.
The total inflow into Krishna basin reservoirs was reported at around 2,62,401 cusecs. The Almatti Reservoir alone received nearly 1.40 lakh cusecs, while the Narayanapura Reservoir recorded an inflow of approximately 1.46 lakh cusecs.
With water levels rising rapidly, authorities are closely watching downstream river conditions and have advised people living in vulnerable and low-lying areas to follow safety instructions.
Cauvery Basin Also Sees Strong Water Inflow
The Cauvery basin received approximately 64,507 cusecs of inflow. Among its major reservoirs, Kabini and Harangi have reached particularly high storage levels.
The Kabini Reservoir had around 18.69 TMC, equivalent to approximately 96% of its gross storage capacity. Harangi stood at nearly 7.90 TMC, or around 93% of its capacity.
The Krishna Raja Sagara (KRS) Reservoir contained about 25.59 TMC, representing approximately 52% of its total capacity.
The continuing inflow into these reservoirs is expected to remain an important factor for irrigation and water management in the Cauvery basin.
Reservoirs Near Full Capacity
Several major Karnataka reservoirs have reached or crossed the 90% storage mark.
The key reservoirs nearing full capacity include:
- Kabini – 96%
- Harangi – 93%
- Almatti – 90%
- Narayanapura – 88%
As reservoir levels rise, water is being released through dam gates into downstream river channels where necessary. People residing close to riverbanks and in low-lying locations have been advised to remain alert because sudden increases in downstream flows can create flooding risks.
Statewide Storage Position
Karnataka’s major reservoirs have a combined gross storage capacity of approximately 895.65 TMC. As of August 4, the total water available in these reservoirs stood at around 546.11 TMC, meaning the reservoirs were collectively about 61% full.
The major reservoirs together recorded a total inflow of approximately 4,03,022 cusecs during the day.
Hydel reservoirs accounted for around 6.6 TMC of the day’s storage increase, while the Cauvery basin contributed approximately 5.6 TMC. The Krishna basin recorded the largest share at around 22.7 TMC.

Water Situation Improves Across Karnataka
The latest figures indicate a substantial improvement in reservoir inflows following widespread rainfall. Although the state’s total storage remains below last year’s level for the same period, the recent surge in inflows has accelerated the filling of several important reservoirs.
With more rainfall expected in catchment areas, water levels could rise further in the coming days. Authorities are expected to continue monitoring reservoir inflows, dam releases and downstream river conditions closely.
For farmers, the improved storage provides greater confidence regarding irrigation availability, while higher reservoir levels also strengthen the state’s water security for the coming months.
