3. INTRODUCTION
• The Pong Dam, also known as the Beas Dam, is an earth-fill
embankment dam on the Beas River in the state of Himachal
Pradesh, India, just upstream of Talwara.
• As the second phase of the Beas Project construction on the dam
began in 1961 and was completed in 1974.
4. HISTORY OF PONG DAM:
A reservoir has been constructed on the river Beas in the wet land of
Shivalik hills of Kangra district of Himachal Pradesh, which has been
named as Maharana Pratap Sagar. It is also known as Pong reservoir or
Pong Dam.This dam was built in 1975 named in honor of Maharana
Pratap, this reservoir or lake is a famous wildlife sanctuary and one of
the 25 international wetland sites declared by Ramsar Sammel in
India.The reservoir stretches to an area of 24,529 hectares (60,610
acres), and part of the lakes is 15,662 hectares (38,700 acres).Pong
reservoir is the most important fish reservoir in the foothills of the
Himalayas in Himachal Pradesh. In this reservoir, majestic fish is found
in excess.
5. DESIGN OF PONG DAM
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 m3
(46,432,247 cu yd) and its crest sits at an
elevation of 435.86 m (1,430 ft) above sea level. The dam's spillway is
located on its southern bank and is a chute-type controlled by six radial
gates. Its maximum discharge capacity is 12,375 m3
/s (437,019 cu ft/s).
The reservoir created by the dam, Maharana Pratap Sagar has a grosse
capacity of this area of pong dam 8,570,000,000 m3
(6,947,812 acre⋅ft)
of which 7,290,000,000 m3
(5,910,099 acre⋅ft) is active (live) capacity.
The reservoir has a normal elevation of 426.72 m (1,400 ft)
and catchment area of 12,560 km2
(4,849 sq mi). The reservoir reaches
from the dam to 41.8 km (26 mi) upstream in length and covers a
surface of 260 km2
(100 sq mi). Located at the base of the dam is its
power house. It is supplied with water via three penstocks which each
meet a 66 MW Francis turbine-generator located inside the Bhatoli
phakorian. The dam's elevation to the power house provides a
maximum of 95.1 m (312 ft).
7. The working of this dam is similar to conventional dams. In this dam,
the water is released, after that it spins the turbines connected to a
generator and produces electricity. The water, then returns to the
river on the downstream side of the dam.
SPILWAY
Spillway is located on its southern bank and is a chute -type controlled
by six radial gates. Its Maximum discharge capacity is 12,375 M/s
(437.019CU FT/s)

ADVANTAGES OF DAM
• Reduces flooding that would normally occur in the summer and
reduces drought that would normally occur in the winter.
• Electricity is produced by the dam foe local towns farms and
factories.
• Water is stored behind the dam which can be used for irrigation
and for supplying growing cities such as las vegas.
• There is year-round supply of celan water for us cities.
DISADVANTAGE OF DAM
• Land is lost to flooding when making the dam.
• Sediment has build up behind the dam which affects the working
of the hydroelectrical power (HEP) generation.
• Less sediment flowing down the river has disrupted the habitat
for native fish.
