the last few weeks there has been little solid information about the state of the dam, although in Pakistan the violent response by the authorities to a demonstration by displaced people, which resulted in the deaths of two men, has been <a href=\"http:\/\/pamirtimes.net\/2011\/08\/20\/more-than-20-men-held-in-hunza-in-early-morning-raid\/\">a major news story<\/a>.<\/p>\n<p>This new image

more flow through the spillway than in the earlier image, and there appears to have been some downstream erosion through widening of the channel.\u00a0 However the flow is still being controlled by the narrow section at the dam crest, which appears to have undergone little change.<\/p>\n<p>Summer is now almost over in this part of northern Pakistan, such that flows will start to reduce again in the next few months.\u00a0 It will be interesting to see whether the government uses this coming winter to reduce the height of the dam.<\/p>\n<!-- AddThis Advanced Settings generic via filter on
