Tarbela can absorb Hunza water11 May 2010
ISLAMABAD: The overflowing Hunza lake does not pose any threat to Tarbela dam which has sufficient capacity to store additional water. Sources in the Indus River System Authority said the water level in Tarbela currently stood at about 1,388 feet, just above the dead level of 1,378 feet, that meant it still had more than 160 feet of capacity to be filled. They said the storage level could be raised by 10 feet a day till such time it reached 1,500 feet. When Tarbela's storage level crosses 1,500 feet, safety require it to be filled at the rate of two feet a day. The sources said Wapda had not intimated it about any decision to release water from the dam in anticipation of any unusual water inflows. On Tuesday, Irsa increased water releases to Sindh from 60,000 cusec to 70,000 cusec to meet its additional irrigation requirements and Balochistan's share has been enhanced to 6,000 cusec from 2,000. The sources said a delay in undertaking a study to assess the impact of rising water level at Hunza had fuelled apprehensions that the lake might overflow and people in large areas in downstream Hunza had moved to other places. They said the water level at Hunza had increased to 314 feet and the lake had expanded to over 15 kilometres. The sources said an official of the federal flood commission who had supervised the study had been sent to the National Disaster Management Authority on deputation despite initial opposition by the NDMA.
