The introduction of barrage-controlled irrigation system resulted in more timely water supplies for the existing cultivated areas of Sindh province of Pakistan.

[2] Sindh survives almost entirely on the water of the River Indus as there is very limited groundwater available.

Various sources estimate that its volume is between three and five MAF scattered in 28 per cent of the geographical area of Sindh.

To revitalise its water storage capacity and distribution efficiency, the Government of Pakistan embarked upon a massive rehabilitation work of Sukkur Barrage.

The retaining wall of the barrage has 66 spans (outfall gates), each 18 metres (60 ft) wide and weighing 50 tons.

In fact Nara Canal is not a man-made canal as it was the southernmost part of Hakro River which emanated from the foothills of Sutlej which after traversing through the Punjab and Bhawalpur plains joined Nara through Raini River, the remnants of which are still exiting in Ghotki District of Sindh Province.

Cotton, wheat and sugar-cane are the main crops grown on this canal system.
