    The document provides information about the Mangla Dam project in Pakistan. It discusses the key details of the original dam project such as its size, structures, and impact. It then summarizes the proposal to raise the dam by 30 feet, which would increase water and energy capacity. Some of the main impacts would be submerging additional land and displacing more households. The raising project involves many of the same parties as the original and includes compensation for affected residents.
