The Kaptai Hydropower Plant authorities have opened 16 spillway gates of the dam to discharge excess water into the Karnaphuli River, following a sharp rise in Kaptai Lake's water level caused by upstream hill runoff.
Engineer Mahmud Hasan, manager of the Hydropower Plant, said that the gates were opened at 3:00am early Wednesday, each lifted by three and a half feet, and approximately 63,000 cusecs of water per second is now being released into the river.
"The water level of Kaptai Lake was recorded at 108.90 feet mean sea level at 8:00am Wednesday, while the reservoir's maximum holding capacity is 109 feet mean sea level," he added.
He further mentioned that water is being discharged to keep the level from exceeding the danger point, and the volume of release will depend on further rise of inflow into the lake.
Meanwhile, rising waters of Kaptai Lake have already inundated several low-lying areas of Rangamati town and adjoining upazilas.
