Islamabad: Around 10 billion tonnes of silt has accumulated in Tarbela Dam, cutting its designed capacity by more than 40pc, a Senate panel was told on Monday. In a briefing to the Senate Standing Committee on Water Resources, officials of Water and Power Development Authority (Wapda) said the sedimentation due to silt will also impact the power generation capacity of Pakistan’s second-largest reservoir. The silt, accumulated over decades, has now taken the shape of a ‘mountain-like structure,’ just four miles away from the dam’s structure, they said.
