The water level in Kerala's Idukki dam further decreased on Sunday and now stands at 2,399.28 feet even as parts of Ernakulam and Thrissur districts still remain submerged.
The district of Idukki recorded 90mm of rain for a period of 24 hours on Saturday morning which receded to 40mm on Sunday morning, according to weather authorities.
Even as the water level of the dam was now below the 2,400 feet mark, district authorities said that the decision to close down the five floodgates will be taken at a later date depending on the amount of rains.
At present, all the five floodgates of the dam are open and in a second, 7.50 lakh litres of water are being sent out to the Periyar river which touches parts of Thrissur and Ernakulam districts, causing floods resulting in the evacuation of over 10,000 people.
But officials in Ernakulam and Thrissur on Sunday said the situation was under control and the water level of the river has come down which may allow some people to return to their homes.
"As the first step for the families to return, various volunteers along with health officials will first reach the homes and clean up," a government official at a relief camp in Ernakulam said.
The situation in the hilly district of Wayanad, which has seen massive destruction to crops and properties, on Sunday looked a bit grim with intermittent heavy rains pounding the region.
The day's forecast points to more rains with chances of landslides and mudslips .
Chief Minister Pinarayi Vijayan is monitoring the situation and with Union Home Minister Rajnath Singh who is slated to arrive here on Sunday afternoon, will take an aerial survey of the flood ravaged places.
