3. INTRODUCTION
oThe Pong Dam, also known as
the Beas Dam, is an earth-fill
embankment dam on the Beas
River just upstream of Talwara
in the state of Himachal Pradesh
India. The purpose of the dam
is water storage for irrigation
and hydroelectric power
generation. As the second phase
of the Beas Project, construction
on the dam began in 1961 and
was completed in 1974.

4. Background
The idea for a dam on the Beas at the Pong site was first proposed
in 1926 and subsequent surveys of the Indus River and its
tributaries were ordered by the Punjab Government in 1927.
Interest in the dam declined after the report deemed the project
difficult because of flood waters. In 1955, geological and
hydrological studies were carried out on the Pong site and an
embankment design was recommended. In 1959, extensive studies
were carried out and recommended an embankment dam with a
gravity section. A final design was issued and construction began
in 1961 on the dam which was called Beas Project Unit II - Beas
Dam. The Pandoh Dam 140 km (87 mi) upstream being the Beas
Project Unit I. It was completed in 1974 and the power station was
later commissioned between 1978 and 198

5. DESIGN
The Pong Dam is a 133 m (436 ft) tall and
1,951 m (6,401 ft) long earth-fill
embankment dam with a gravel shell. It is
13.72 m (45 ft) wide at its crest and 610 m
(2,001 ft) wide at its base. The total volume
of the dam is 35,500,000 m
3

(46,432,247 cu yd) and it its crest sits at an
elevation of 435.86 m (1,430 ft) above sea
level

10. ADVANTAGES OF DAM
o1. Once a dam is constructed, electricity can be produced at a constant
rate.
2. If electricity is not needed, the sluice gates can be shut, stopping
electricity generation. The water can be saved for use another time when
electricity demand is high.
3. Dams are designed to last many decades and so can contribute to the
generation of electricity for many years / decades.
4. The lake that forms behind the dam can be used for water sports and
leisure / pleasure activities. Often large dams become tourist attractions in
their own right.
5. The lake's water can be used for irrigation purposes.
6. The build up of water in the lake means that energy can be stored until
needed, when the water is released to produce electricity.
7. When in use, electricity produced by dam systems do not produce green
house gases. They do not pollute the atmosphere

11. DISADVANATGES
Dams are extremely expensive to build and must be built to a very
high standard.
2. The high cost of dam construction means that they must operate
for many decades to become profitable.
3. The flooding of large areas of land means that the natural
environment is destroyed.
4. People living in villages and towns that are in the valley to be
flooded, must move out. This means that they lose their farms and
businesses. In some countries, people are forcibly removed so that
hydro-power schemes can go ahead.
5. The building of large dams can cause serious geological
damage. For example, the building of the Hoover Dam in the USA
triggered a number of earth quakes and has depressed the earth’s
surface at its location.
