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

4. 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.

storm water drains and road side drains;
Removing silting;
Constructing retaining walls;
Laying of beds;
Green area development
7. 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.
