Authorities have sounded the alarm after a mudslide blocked the Ghizer River, creating a seven-kilometre-long artificial lake that now threatens to unleash devastating floods downstream.

Residents along the Indus River near Chilas and surrounding districts are being evacuated to safer locations.

Lake formed by mudslide

The National Disaster Management Authority (NDMA) confirmed that the mudslide, which struck on Friday, completely blocked the Ghizer River channel, creating what officials described as a “dam-like structure.” The lake, stretching 4 miles, has raised fears of a sudden burst that could cause large-scale destruction.

“This new lake can cause a catastrophic flood,” warned Zakir Hussain, the director general of the Provincial Disaster Management Authority (PDMA). Four districts — Ghizer, Gilgit, Astore, and Diamer — are under direct threat.

Swift evacuations and Section 144 imposed

The district administration has imposed Section 144, barring people from approaching the Indus River. Residents of Ghizer Taalidas have been shifted to tent settlements, while those living near the Indus in Chilas have been directed to move to safer areas.

Provincial government spokesperson Faizullah Faraq said that an early warning system in Ghizer district was not functional, but the timely alert by a shepherd on higher ground saved hundreds of lives. Nearly 200 residents were rescued after the crashing herd spotted the mud flow, alerted villagers and warned authorities.

Similar mud flows landed in the river from different mountainsides, Faraq said. The lake has started discharging water, meaning the threat of a burst is receding, but flash floods in downstream districts cannot be ruled out until the lake is completely cleared, he added. The communities downstream have been directed to stay on high alert and vacate areas along the river, he said further.

Relief efforts and govt response

The Gilgit-Baltistan chief minister visited the affected area, met with displaced families, and reviewed ongoing relief operations. He directed immediate restoration of water, electricity, and communication infrastructure on an emergency basis.

The CM also announced cash rewards and certificates for the shepherd who raised the alarm and the youth who performed courageous rescues in Ghizer Dayan. Plans are underway to establish an alternative village for displaced families on a permanent basis, with appeals to the Prime Minister for support.

Ongoing threats

Meanwhile, Pakistan is already reeling from widespread monsoon devastation, with at least 785 deaths reported nationwide since late June. Officials fear additional rain spells could worsen the crisis before September 10.
