Flood alert issued as Poondi approaches FRL
The inflow of water into the Poondi Reservoir has increased due to heavy rainfall in the Tiruvallur district watershed, increased supply to the Krishna River and the release of excess water of Ammapalli Reservoir in Andhra Pradesh. The increased water flow led to a rapid rise in the water level in Poondi, after which the government released 1,000 cusecs of water from the reservoir at 2 p.m., according to a statement.
As the released water is expected to reach the sea through the Kosasthalai River, there is a risk of flooding. Residents of areas near the river – Manali, Ennore and 20 other villages – have been urged to stay safe. Residents of low-lying areas have also been urged to take flood safety measures.
The Poondi Reservoir has a total height of 35 feet with a storage capacity of 3.231 million cubic feet. Due to heavy rains in the watersheds, the reservoir received a good inflow of 1,691 cubic feet on Sunday morning, causing storage levels to reach an alarming level of 2,807 mcft at a height of 33.95 feet. As it was expected to reach the full reservoir level (FRL) of 34 feet by Sunday afternoon, the state government decided to release 1,000 cubic feet of excess water into the Kosathalai River. As more water is expected to flow into the reservoir, the authorities have decided to release the excess water gradually.
