The 2010 Pakistan floods began in July 2010 following heavy monsoon rains in the Khyber Pakhtunkhwa, Sindh, Punjab and Balochistan regions of Pakistan. Present estimates indicate that over two thousand people[2] have died and over a million homes have been destroyed since the flooding began.[3] The United Nations estimates that more than 21 million[4] people are injured or homeless as a result of the flooding, exceeding the combined total of individuals affected by the 2004 Indian Ocean tsunami, the 2005 Kashmir earthquake and the 2010 Haiti earthquake.[5] At one point, approximately one-fifth of Pakistan's total land area was underwater due to the flooding.[6][7][8]
UN Secretary-General Ban Ki-moon has asked for an initial $460 million for emergency relief, noting that the flood was the worst disaster he had ever seen. 50% of the relief funds requested have been received as of 15 August 2010.[9] The U.N. is concerned that aid is not arriving fast enough, while the World Health Organization reported that ten million people were forced to drink unsafe water.[10] The Pakistani economy has been harmed by extensive damage to infrastructure and crops.[11] Structural damages are estimated to exceed 4 billion USD, and wheat crop damages are estimated to be over 500 million USD.[12] Officials estimate the total economic impact to be as much as 43 billion USDSituation of Hunza lake.....
The Chairman of the National Disaster Management Authority (NDMA), Retired Lt General Nadeem Ahmed said water outflow from the Hunza lake is expected to spill over on May 28.
According to the National Disaster Management Authority, 2050 cusecs water is entering the lake due to melting glaciers while the water release is 197 cusecs.
Landslides are also expected as the water level in the lake has increased to 3.1 feet in the last 24 hours.
The Hunza Deputy Commissioner Zafar Waqar Taj said that lake water had inundated low-lying areas and the rate of increase in the lake’s water level had been steady. People from the 32 flooded villages have been evacuated and are not allowed to go back. All downstream villages have been evacuated.
The government of Khyber-Pukhtunkhwa province has been asked by Pakistan’s National Disaster Management Authority to prepare for a possible emergency in the districts of Shangla, Mansehra, Kala Dhaka and Kohistan, downstream from the Hunza Nagar district.
The region is under threat from flooding from a lake that formed after a landslide. Villages in Hunza-Nagar are reported to have been flooded. According to the FOCUS Humanitarian Assistance NGO operating in the area, villages in the Kohistan district are under threat, with some 30,000 to 50,000 people possibly vulnerable. The district has a scattered population of about 500,000, according to official figures.
Meanwhile, a medical team sent by the Punjab government is also arriving in Hunza today, while air service stands operational to provide relief goods and food to the affectees.
Hunza Lake( history may repeat itself)
The risk of flood in Hunza, Gilgit and the downcountry as a result of the lake formed at Attaabad due to a landslide isn’t the first time that a natural disaster of such a big magnitude is posing threat to life and property in the area.
In 1840, a similar situation arose at Boonji in Gilgit area and caused a devastating flood. History buff Ali Jan has sent excerpts from Edward W Knight’s book, Where Three Empires: A Narrative of Recent Travel in Kashmir, Western Tibet, Gilgit and the Adjoining Countries, in which he writes about the 1840 flood. The book was published by Longmans, Green & Co., 1905.
The author Edward Knight wrote that the flood started in Gilgit after a landslide as a huge chunk of mountain fell into the River Indus, blocked the flow of water and formed a long and deep lake that burst and caused devastation. The flood not only damaged land and habitation downstream but it also swept away the Sikh army camping by the riverside in faraway Attock.
Ali Jan has also posed a question: Is history repeating itself? One hopes it doesn’t happen this time. Below is the relevant excerpt from that book: “Boonji signifies fifty in the language of these parts, and the name as it is said was given to this district because there were once fifty villages and considerable cultivation in the now desert vale of the Indus between the mouths of the Astor and Gilgit streams. An extraordinary flood in 1840, which is striking example of the huge scale of the convulsions of Nature in this region of gigantic mountains, was no doubt the primary cause of the present desolation. Near the Hattu Pir a whole mountain suddenly fell into the Indus, forming a great dam across the river, and preventing all outlets. The waters rose behind this dam for six months, flooding all the plain of Boonji and the valley of the Gilgit River, till a lake was formed 35 miles in length, and of great depth. At last, the rising lake reached the top of the dam, overflowed it, forced a breach, and then, with irresistible power, the immense mass of water opened a broad, deep channel through the opposing mountain. The liberated Indus once more rushed down its gorges and the last lake was drained in one day. Hundreds of miles away, the great wave of the flood overwhelmed a Sikh army that was encamped near Attock, and the loss of life and property all down the valley of Indus was beyond computation.”
