The landslide killed twenty people and blocked the flow of the Hunza River for five months. The lake flooding has displaced 6,000 people from upstream villages, stranded (from land transportation routes) a further 25,000, and inundated over 12 miles (19 km) of the Karakoram Highway.
The lake reached 13 miles (21 km) long and over 100 metres in depth by the first week of June 2010 when it began flowing over the landslide dam, completely submerging lower Shishkat and partly flooding Gulmit. The subdivision of Gojal has the greatest number of flooded buildings, over 170 houses and 120 shops. The residents also had shortages of food and other items due to the blockage of the Karakoram Highway. By June 4 water outflow from the lake had increased to 3,700 cu ft/s (100 m3/s).
On on 24 Feb 2012 this bloodiest lake was destroyed by the government and as a result of the damming of Hunza River, five villages north of the barrier were flooded. One village, Ayeenabad, was completely submerged. Major portions of another village, Shishkat, was also submerged. Around 40 % of the village of Gulmit, which also serves as the headquarter of Gojal Valley, was also submerged. Significant portions of land in Hussain and Ghulkin villages of Gojal also got submerged as a result of the surging lake.
