Authorities said shutter number 3 would be raised to 160 cm while two and four would remain at 120 cm and shutter one and five at 40 cm. The water level has reached 2,387.20 feet, which prompted the authorities to increase the shutter height. The Idukki district administration has asked the people to remain vigilant. Amid all this, the four spillway shutters of the Malampuzha dam were raised by 80 cm today. As the inflow into the Banasura Sagar reservoir in Wayanad district has increased, the district administration has informed that apart from the already-opened shutters, one more would be opened by 10 cm. “This might increase the water level in the Kabani river by 10 cm,” the authorities said.
