    Tajikistan Dam could break

    May 2007 - The natural dam holding Lake 
    Sarez in southeastern Tajikistan could break in the event of a major 
    landslide, putting thousands of homes in the region at risk of 
    devastation. 
    Experts say that in addition to introducing an early warning system and 
    making local residents aware of the problem, serious research should be 
    done to find a long-term solution to the problem. This should involve all 
    four of the countries that would be affected if the lake broke its banks. 
    Last week, people living in the Bartang valley of the southeastern 
    Badakhshan region received training in emergency procedures for the 
    eventuality that the dam ruptures, the Aziya Plus news agency reported. 
    The training was part of a World Bank funded project aimed at reducing the 
    risk posed by the lake. 
    Lake Sarez lake, lying at an altitude of over 3,000 meters (9,842 feet), 
    was formed in 1911 when an earthquake caused a huge landslide which 
    blocked the River Murghab. 
    Lake Sarez, deep in the Pamir mountains of Tajikistan, was created 90 
    years ago when a strong earthquake triggered a massive landslide that 
    became a huge dam along the Murghob River, now called the Usoi Dam. (Photo

    It is thought that another strong earthquake could break this natural dam 
    and set off a huge wave of water that would swamp towns and villages in 
    Tajikistan, Afghanistan, Uzbekistan and Turkmenistan, affecting an area 
    where around six million people live. 
    Leonid Papyrin, an expert with the Moscow Centre for Regional Geophysical 
    and Geo-ecological Studies, says the dam will inevitably break at some 
    point in the future, but adds that "it is impossible to predict when it 
    will happen – tomorrow or in a hundred years." 
    Papyrin said there is virtually no current research despite the need for 
    extensive studies of seismic activity in the region. 
    However, Gulsara Pulatova, a United Nations senior advisor on disaster 
    risk reduction, says recent studies show the natural plug is much more 
    stable than anticipated. 
    "It turns out the risk is not as high as we imagined. Many people 
    exaggerate it, but it’s just panic-mongering," she said. 
    But Pulatova accepts the need for scientists to continue studying the dam, 
    as new leaks keep appearing and earthquakes could cause another landslide. 
    
    Sobit Negmatullaev, a seismologist currently working as an adviser on the 
    World Bank’s Lake Sarez Risk Mitigation Project, says that an 
    international conference will be held in Dushanbe on May 22-23 to discuss 
    a long-term solution that would entirely eliminate the danger of the lake 
    bursting. 
    Sixty-one kilometers long, Lake Sarez lies in an earthquake-prone area. 
    
    "There are a lot of options - some water can be drawn off the lake, or 
    drained via tunnels, [the water flow] can be regulated, and there are a 
    lot of other ways to make Sarez safe," said Negmatullaev. 
    Uktam Murtazaev, acting director of the Tajik branch of the Scientific and 
    Information Centre of the Interstate Coordination Water Commission, says 
    the lake will need significant investment and appropriate infrastructure 
    for these measures to work. 
    Protection measures should be economically viable, he said. 
    The lake’s waters could be exported as drinking water, used to irrigate 
    three million hectares (7.4 million acres) of land in neighboring 
    Afghanistan, and directed into new reservoirs that would power 
    yet-to-be-built hydroelectric stations on the River Panj, the upper part 
    of the Amu Darya. 
    Aminjon Huseinov, who is in charge of matters relating to Lake Sarez at 
    the Ministry for Emergency Situations, agrees that huge investment is 
    needed to protect the lake, but says the Tajik government does not have 
    the budget to do this. 
    "A solution to this problem requires joint efforts from all the Central 
    Asian states, Afghanistan and the international humanitarian organisations 
    operating in our region," he said.
