According to Chennai Metropolitan Water Supply and Sewerage Board (Metrowater) data, the five lakes - Poondi, Cholavaram, Redhills, Thervoy Kandigai and Chembarambakkam had 11,097 mc ft of water on Wednesday morning. The storage is 111 mc ft more than the amount of water that these lakes had on Tuesday. One million cubic feet (mc ft) is equal to more than 2.83 crore litres of water. On the same day last year, the lakes had only 5,767 mc ft of water.
It may be noted that the Public Works Department (PWD) had maintained the water level in Poondi lake the same for the last two days despite water from catchment areas and Kandaleru reservoir flowing into the lake by releasing more than 1,000 cusecs at times to prevent damage to the lake. As the water storage in Redhills lake reached 3,249 mc ft of total 3,300 mc ft, excess water was released on Tuesday. Also, water was released from Chembarambakkam lake as the water level crossed 23 feet for the first time since 2015, when the city witnessed one of its worst floods.On Tuesday, the lakes had combined storage of 10,986 mc ft. “As the rains stopped after Wednesday afternoon, the release of water from Redhills lake and Chembarambakkam lake gradually decreased. If the city received continuous rain for another 5 hours with the same intensity, it would have become dangerous,” a PWD source said.
Meanwhile, as many as 821 lakes in Kancheepuram and Chengalpattu districts reached its full capacity after heavy rain on Monday. This is the first time most of the lakes have been filled up after five years. Among the 909 lakes, 821 lakes filled up by 100 per cent, 83 lakes got filled by 75 per cent and only five lakes have water less than 50 per cent.
