The water level in the Idukki reservoir is abysmally low as the rainfall in the catchment area is yet to make an impact. The water level on Friday was 2,302.30 ft against 2,306.78 ft on the same day last year.
The rainfall recorded in the catchment area was low and it needed at least three days’ continuous rainfall to make an impact on the reservoir, said an official of the Dam Monitoring and Research Cell of the KSEB at Cheruthoni. The rainfall in the catchment area on Friday was 9.4 mm and production at the Moolamattom Powerhouse was 19.45 lakh units.
The production at the powerhouse was at a reduced level so as to continue production even in case of a delayed monsoon. The inflow of water through the main tributary of the Periyar had not shown a marked increase and there was no inflow from the other diversion dams.
The official said during the period since the summer rains started, the water level continued to decline every day.
