The partition of irrigation systems

A connected canal network

The 1947 Partition divided a Punjab irrigation system whose rivers, headworks and canals had been managed across the former province. Political borders did not follow the course of every channel. Researcher Amit Ranjan describes the division of the Upper Bari Doab Canal and the placement of important headworks in East Punjab. Water taken from a river at one location could serve agricultural land across the new border, creating practical and political problems for the two administrations. The geography of the system is essential to understanding the dispute; a line on a map did not create separate river basins.[1]

The 1948 dispute

Ranjan’s study explains that a standstill arrangement maintained earlier allocations temporarily, and that supplies to certain canals were stopped on 1 April 1948 after it expired. It discusses subsequent inter-dominion negotiations and an agreement on 4 May. The two governments advanced different positions about water and payment. This historical account should not be used as a statement about present flows or current legal obligations. The interruption and negotiations affected a network on which cultivators depended, but the effects varied across canals and localities. Administrative records and local accounts can help establish those differences.[1]

Engineering a new system

Historian David Gilmartin examines how Pakistan’s post-Partition approach combined engineering, regional politics and international negotiation. He describes a connecting channel that carried Chenab water beneath the Ravi to supply branches previously dependent on headworks across the border. Such projects were part of a longer process of adapting infrastructure, not an immediate replacement of the entire system in 1947. A later World Bank project report discusses replacement works associated with the 1960 Indus Waters Treaty. Studying these projects alongside farmers’ experiences and environmental records can reveal consequences beyond the engineering plans themselves.[3][2]

Gilmartin identifies this project as the Bambanwala–Ravi–Bedian–Dipalpur Canal, or BRBD. He describes contractors and volunteers, including students from Lahore, contributing labour and recalls how officials presented the work as a national undertaking. The historian’s account connects a physical water route with public mobilisation; it does not tell us the experience of every worker or landholder along the canal.[3]
