The water levels in two important reservoirs.
Details
- Krishnaraja Sagar (KRS) water level breaches 100-ft mark and reaches 102.35 ft due to heavy rainfall in the catchment area.
- Increase in inflow and live storage in the dam, but it's still at 46% of the gross capacity.
- Inflow at 48,025 cusecs in the morning, increased to 49,280 cusecs at night.
- Outflow rate at 5,449 cusecs.
- Future trends depend on rainfall in Kodagu and discharge from Harangi reservoir.
Water Level in Kabini Reservoir
- Kabini reservoir in H.D. Kote taluk of Mysuru district nears full reservoir level (FRL).
- Heavy inflow from rain in the catchment area in Wayanad, Kerala, leads to rise in water level.
- Inflow at 25,485 cusecs, water level at 2,281.27 ft on Tuesday.
- Outflow increased from 15,000 cusecs to 20,000 cusecs, with the possibility of Bidarahalli bridge being partially submerged.
- Kabini typically fills up early in the monsoon season, but this year had scanty rain.
