After three consecutive days of incessant rains, over 200 roads in the state's interiors remained closed to traffic, stranding travellers and commuters.

While the picturesque tourist town Dalhousie recorded the highest rainfall at 180 mm, it was 120 mm in Manali and Kangra each and 108 mm in Palampur.

The highway that connects Manali with Leh in Jammu and Kashmir has been closed for traffic owing to heavy snow since Saturday, an official said.

Authorities said excess water was discharged from the Pandoh diversion dam, located 112 km upstream of Pong dam, as a precaution.

The dam is located on the Beas river in Mandi district. It diverts excess monsoon water towards the Pong dam. Otherwise, it diverts water towards the Satluj which feeds the Gobind Sagar reservoir of the Bhakra dam.

The water levels in the Bhakra dam's Gobind Sagar reservoir and the Pong dam reservoir stood at 1,655 feet and 1,385 feet respectively, an official told IANS.

Official data showed the maximum storage capacity for the Bhakra dam is 1,702 feet and 1,393 feet for the Pong dam reservoir.

Officials said more rains could aggravate the flood-like situation in Punjab and Haryana. All the major rivers of Himachal Pradeh -- the Satluj, Beas and Yamuna -- enter Punjab and Haryana.
