Sindh Irrigation System: 

                                                                                                           Sindh irrigation system depends on "INDUS RIVER". There are Six barrages that are constructed on indus river in order to irrigate the the different areas in pakistan. The river has its estimated annual flow at around  207×10⁹ cubic meter, which making it 12th largest river in the world in terms of annual flow.

As sindh irrigation system consists of three main barrages, in this section only following three barrages of indus river will be discussed here.

1-GUDDU BARRAGE

2-SUKKUR BARRAGE

3-KOTRI BARRAGE

1-GUDDU-BARRAGE : Guddu-barrage is a barrage on the indus river  near kashmore in sindh province Pakistan. President Iskandar mirza laid the foundation-stone of Guddu Barrage on 2nd february 1957. The barrage was completed in 1962 at a cost of 474.8 million rupees and in inaugurated by Field Marshal Ayub Khan.

It is a gate-controlled weir type barrage with a navigation bar lock. The barrage has 64 bays, each 60 feet (18 m) wide. The maximum flood level of Guddu barrage is 26 feet (8 m).

The barrage has a length of  total 1355 meter, and  discharge capacity of 1.2 million cusec (ft³/sec) or (34,000 cumec),  which irrigates 2.9 million acres of  agriculturalland in sindh province, nasirabad & jaferabad districts of balouchistan. The most of area in Sindh province lies in Jacobabad, Larkana and Sukkur districts.

Guddu barrage has a system of three  main canals two at right bank and one at left bank.

RIGHT BANK CANALS:

1-Begar Sindh Feeder (Design discharge = 14,764 cusec)

2-Desert Pat Feeder   (Design discharge = 13,275 cusec)

LEFT BANK CANAL:

1-Ghotki Feeder (Design discharge = 8,490 cusec) 

2-SUKKUR BARRAGE : Sukkur Barrage is the largest Barrage of Pakistan. It was named as Lolyd Barrage after its completion in British Raj in 1932. Sukkur Barrage is on the indus river near by "SUKKUR" city in Sindh Province.

Sukkur Barrage has a length of almost 1524 meters (5001 ft), which irrigates
10 million acres (40,000 sq.km) of sindh province.

Maximum design discharge of Sukkur Barrage is 1500000 cusec and have total design withdrawal for canal is 47,530 cusec.

There are seven Off-taking canals constructed on sukkur barrage, three on Right bank and four on left bank.

RIGHT BANK CANALS:

1-North West Canal            (Design discharge = 9450 cusec)   &    (GCA = 10,27085 acres) 

2-Rice Canal                        (Design discharge = 10658 cusec) &   (GCA = 54,7480 acres) 

3-Dadu Canal                     (Design discharge = 5200 cusec)   &   (GCA = 59,7464 acres)

LEFT BANK CANALS:

1-Nara Canal                        (Design discharge = 13,650 cusec)   &   (G.CA = 21,76494 acres) 

2-Khairpur East Canal      (Design discharge =  2094cusec)   &   (G.CA = 53,1110 acres) 

3-Rohri Canal                      (Design discharge = 14,100 cusec)   &   (G.CA =29,56518 acres) 

4-Khairpur West Canal     (Design discharge = 1940 cusec)   &   (G.CA = 40,9121 acres) 

3-KOTRI BARRAGE : Kotri Barrage was built in 1932 and is about 1.6 kilometers (1600 meter or 5250 ft) long. It is also known as "GHULAM MUHAMMAD" Barrage, was openned in 1955. The canals deriving from it serves a cultivable area of about 5 million acres of ground generating both foodstuff and crops, it is near by Hyderabad district Sindh province of Pakistan. It provides supplementary supply for Karachi city.

Kotrai Barrage has a discharge capacity of 875,000 cusec. it is gate-controlled weir type barrage with a navigation lock. The barrage has 44 bays, each 60 feet (18 m) wide. The maximum flood level of Kotri Barrage is 43.1 feet.

There are Four Off-taking canals constructed on kotri barrage, one at Right bank and three at left bank.

RIGHT BANK CANALS:

1-K.B Feeder     (Design discharge = 9100 cusec)

LEFT BANK CANALS:

1-Linned Chanel / Akram wah         (Design discharge = 3100 cusec)

2-Fulleli Chanel                                   (Design discharge = 14,860 cusec)

3-Pinyari Chanel                                (Design discharge = 13,636 cusec).
