The water level in the artificially formed 16km-long lake on the River Hunza has reached dangerous level as further landslides are exacerbating threat that the lake may burst its banks, report said. The water level has surged further by 5 feet to 357 feet in the lake, just six feet below of water spillways created to release the water. Officials say the water was expected to start draining into spillways later by May 20. Water in the lake was rising by one meter (yard) daily. The lake emerged on January 4 as a result of a massive landslide that killed 20, left about 25,000 people stranded and blocked Hunza river in a remote Himalayan region about 750 kilometres (450 miles) north of Islamabad.
