The heavy rain during the past seven days contributed positively to the Idukki reservoir with a record rise in water level. An official of the Dam Monitoring and Research Station, Vazhathoppe, told The Hindu on Thursday that the water level was 2,338.58 ft compared to the 2,300.9 ft on the same day last year. The level of increase in water level was 2 ft from Wednesday. It started to increase from the lowest this year, 2,,222.8 ft. The water level started to increase from June 8.

Though the southwest monsoon started early this year, the water level in the dam recorded an increase only after the heavy rain. The inflow through the Periyar and other diverted streams continued at the same strength, though the rain subsided on the catchment area on Thursday. The rainfall recorded on Thursday was 50.7 mm. The highest rainfall recorded on the catchment area on a single day was on June 11. It was 110 mm.

The record rainfall in a decade on a single day also led to a record rise in water level. The official said a record rise of 4.5 ft on a single day was during this monsoon season. The power generation at the Moolamattam power house on Thursday was 3.18 mu (million unit), which was 5.12 mu the previous day.

The average water level in all the reservoirs in the State was 35% that was only 11% during the same period last year. On June 7, there was 23% of water in all the 16 reservoirs under the KSEB in the State.

Neryamangalam, Peringalkuthu, and Lower Periyar dams have 100% water level.

The water level in the Mullaperiyar dam on Thursday was 126.7 ft.
