• Chennai: Due to continuous rainfall over the weekend, authorities have released water from four lakes near Chennai, leading to inundation of areas around it.

• Water was released from Chembarambakkam, Porur, Puzhal (picture) and Madurantakam lakes and officials have cautioned people living in low-lying areas. This could flood localities such as Porur, Moulivakkam, Bharaniputhur, Manapakkam, Mudichur, Perungalathur and Pammal.

• Kanchipuram Collector R Gajalakshmi said, "We have to discharge at least the inflow. We do not expect any major impact.“

• According to authorities, nearly 12,000 people have already been evacuated from low-lying areas and have been given shelter in marriage halls and schools.

• After the Porur lake was opened, Moulivakkam, Bharaniputhur and Telliagaram were the first to get flooded. As water levels rose, low-lying areas in Mugalivakkam, Manapakkam and Kolapakkam started to go under a sheet water. An earth-mover was to be used to create a canal in Moulivakkam for the water to flow out.

• Residents of Moulivakkam have expressed anguish. "We have to wade through knee deep water and it is getting worse with more rainfall forecast," said Ramesh. Some even took to social media to express their displeasure with one saying, "Even though the rains have reduced, I have to wade through knee deep water on a bright Monday morning."
