Idukki Dam The Idukki Dam was reopened this evening to control the water level.
The Idukki Dam in Kerala has been reopened this evening to control the water level as the Idukki Dam in Kerala, the largest arch-shaped dam in India, may overflow from the Mullai Periyar Dam at any time. Idukki Dam has been open for the first time in its history in 1981, 1992, 2018. Four years after the fourth time, the Idukki Dam was reopened on October 19 last year and closed on October 27 this year. The Idukki Dam has now reopened for the second time this year.
The water level of Idukki Dam, which is 2,403 feet above sea level, is currently 2,401.50 feet. The dam is receiving 6,500 cubic feet of water per second. At present, the third dam of the Cheruthoni Dam, which drains the surplus water of the dam, has been opened and 60 thousand liters of water is being discharged per second.
It was built across the Periyar near Cheruthoni in Idukki taluka of Idukki district in the state of Kerala. Idukki Dam is the largest arch shaped dam in India. Construction of the dam began in 1969 and opened in 1973. The Idukki Dam with a water capacity of 75 TMC is under the control of the Kerala Electricity Board. The total water level of the dam is estimated at 2,403 feet above sea level. The dam, which generates 750 MW of electricity daily, is powered by the Moolamatram, Cheruthoni and Kulamavu power stations.
The water level of Idukki Dam rose sharply to 2,398 feet due to heavy rains in Idukki, Kerala last October. Four years after the dam’s flood warning was issued for the third phase, on October 19 last year, the three sluice gates of the dam were raised by 35 cm, discharging 1 lakh liters of water per second.
Then the rain subsided and the water level of the dam dropped to 2397.90 feet. The Idukki Dam was closed on October 27 due to low water levels. In this situation, the water level of Mullaiperiyaru dam is being maintained between 142 and 141 feet.
The third stage of the flood alert has been issued for the Mullaiperiyaru Dam and the Idukki Dam. An official letter to this effect has been submitted to the Idukki District Administration on behalf of the Tamil Nadu Public Works Department. More than 10,000 cubic feet of water per second was released from the Mullaiperiyaru dam on Monday night. 2,100 cubic feet of water per second was released into Kerala as surplus water on Tuesday evening.
As the Idukki Dam continues to overflow, the water level from the Mullaiperiyaru Dam may increase at any time, causing the Idukki Dam to control its water level. The Idukki Dam was reopened on Tuesday evening.
The water level of Idukki Dam, which is 2,403 feet above sea level, is currently 2,401.50 feet. The dam is receiving 6,500 cubic feet of water per second. Currently, the third dam of the Cheruthoni Dam, which drains the surplus water of the dam, is being raised by 60 cm and discharged 60 thousand liters of water per second.
