[6] Another colonization scheme which extended the canal network in what is now southern Punjab was the Sutlej Valley Project which was undertaken by the British Indian government in 1922-33.

[7] The Indus Waters Treaty which was signed between India and Pakistan in 1960 was a major watershed in the history of development of irrigation infrastructure in the province.

[8] The treaty gave the rights of the three eastern rivers of the Indus basin namely Ravi, Sutlej and Beas to India and thus necessitated the construction of inter river link canals to haul water from Indus, Jhelum and Chenab to the eastern parts of the province.

It was after this treaty that Pakistan built Tarbela and Mangla reservoirs to store monsoon water for winter months to continue to irrigate the fields year round.

The second major development post independence in the history of irrigation in Punjab was 1991 Water Accord between all the four provinces of Pakistan.

This accord gave Punjab province 55.94 million acre feet of water share annually for its irrigation and drinking usages.

The department has also initiated works on Dadocha Dam which will supply 35 million gallons of drinking per day to the people of Rawalpindi.

The new digital water revenue assessment and collection system was launched in the pilot phase in Kasur, Sheikhupura, Khanwah and Layyah Canal Divisions.
