  1. 1.  Mangla Dam  The dam was constructed between 1961 to 1967 across the Jhelum River, about 67 miles (108 km) south-east of the Pakistani capital, Islamabad in Mirpur District of Azad Kashmir, Pakistan. The Mangla Dam components include a reservoir, main embankment, intake embankment, main spillway, emergency spillway, 5 tunnels and a power station

  3. 3. Conservation of Water Resources in Pakistan Water use practices in this country are not in accordance with water conservation and quality requirements. Most of the water is polluted and unhygienic for drinking purpose both for human and animals. Every year due to floods a lot of water flows down towards sea and its inundation causes huge and irreparable losses to human lives, property and assets of public and private sectors. For overcoming such menaces small and flood dams at different sites should be constructed. The critical issue in water sector is to resolve the scarcity of water through augmentation and conservation. The argumentation of water supplies by implementing high priority projects like Raising of Mangla Dam.

  6. 6. Economic Impact of lake conservation   The visual quality of the communities built around the lake is highly dependent on the condition of the water body and the lakeshore. The natural beauty of the lake is part of the quality of life for lakeshore property owners and the entire community. The quality of a lake directly affects community property values and, therefore, the local tax base A properly managed lake provides recreational opportunities for the citizens and mode of revenue for the Government for maintaining the lake.
