The spill gates were opened to release excess water and would remain open till the rainfall in dam's catchment subdued, said an official.
Meanwhile, water in the Pong dam across the Beas river was also rising, officials said on Saturday.
"The water level in the Bhakra Dam's Gobind Sagar and the Pong Dam reservoir stood at 1,674 feet and 1,364 feet, respectively," a BBMB official told . The BBMB manages both the dams built on the Punjab-Himachal border, he said.
