3. Introduction
Pakistan’s Indus Basin Irrigation System (IBIS) is
the strong heart of the country’s economy. Its
creation is a tribute to the British irrigation
engineers who created the original system (1847-
1947) that Pakistan inherited in 1947 and to the
Pakistani irrigation engineers and institutions
(particularly the Water and Power Development
Authority [WAPDA] and the provincial irrigation
departments)

4. Introduction
who have spent the last 60 years adding new
dams and barrages, building new link and branch
canals, and modernizing and maintaining the
world’s most complex and extensive irrigation
system. From the 1950s onward, the IBIS has
also been the product of the generosity and
intellectual input of a host of international experts
and international institutions, particularly the
World Bank.

5. The Indus Basin: The First Decade
1947-1957
Pakistan at this time was overwhelmingly rural.
There was a magnificent canal irrigation system
based on the River Indus and its five tributaries
(the Jhelum, Chenab, Ravi, Sutlej, and Beas), but
it was plagued by its seasonal nature and lack of
surface storage (nearly half the flows went to sea
unused in the summer, with less than 2 feet/acre
left for the irrigated land).

The irrigation system during the 1950s (largely
inherited pre-1947) consisted of 10 barrages
(Thal, Jinnah, Taunsa, Guddu, Sukkur, Kotri,
Trimmu, Dipalpur, Suleimanke, Islam, and
Panjnad) and 35,000 miles of canals. India had
started depriving Pakistan of water from the three
eastern rivers, i.e., the Ravi, Sutlej, and Beas
from March 1948.

This led Pakistan to negotiate and sign the Indus
Water Accord (IWA) in 1960, with India giving
Pakistan the rights to the Indus, Jhelum, and
Chenab, and India the rights to the Ravi, Sutlej,
and Beas in perpetuity.

8. The Indus Basin Replacement
Works (1960-80)
The total replacement cost of the infrastructure is
currently estimated at more than $60 billion,5
and of these, the two major dams (Tarbela and
Mangla), a syphon-cum-barrage (Mailsi), five
barrages (Chashma, Rasul, Qadirabad, Marala,
and Sidnai), and eight major link canals were
built under the Indus Basin Replacement Works.

10. IBIS Investments in the Last
Decade 2000-2010
The last decade has seen the initiation and
completion of a number of important projects
relating to the Indus Basin, financed in large part
by the Government of Pakistan itself. These
include:
1. The Mangla Dam Raising Project 2003-2010
(raising the Mangla Dam 30 feet and thereby
adding an additional 2.9 MAF to its existing
capacity of 6 MAF at an original cost of Rs 63
billion)

13. Indus basin water strategies in
Pakistan
Many systems are use in Indus basin
water strategies in Pakistan:
1. Barrage
2. Dam
3. Headwork
13
14. Dams
A barrier constructed across a waterway to
control the flow or raise the level of water.
A dam is a barrier that impounds water or
underground streams. The reservoirs
created by dams not only suppress floods
but provide water for various needs to
include irrigation, human consumption,
industrial use, aquaculture and navigability.
A dam is also the basic key element for
hydropower generation.

The project was designed primarily to increase the
amount of water that could be used for irrigation
from the flow of the Jhelum and its tributaries. Its
secondary function was to generate electrical power
from the irrigation releases at the artificial head of
the reservoir. The project, though not initially
designed as one, also works as a flood control
structure by retaining water during the flood-prone
season of Monsoon.

44. Barrage
What is a barrage?
An artificial structure or obstruction placed in
river or water course , to increase the depth of
water(to some feet), so that the water can be
diverted into canals is called barrage.
A type of dam which consists of a line of
large gates that can be opened or closed to
control the amount of water passing the dam
44
45. What is difference between Barrage
and Headworks?
The head works are built on river or water
course between two banks at the same level of
river to control water, distribute it through canals
for irrigation or other purpose of supplying water.
Barrage is made in similar way but main
difference is that barrage is designed in such a
way so that it could increase the water level and
serve as a storage. Electricity can be produced at
a barrage after construction of hydro power
plants but could not be at a head work.
