The results of a research investigation into water management practices during the commissioning of a paddy irrigation project are described. Investigations centred on the water issues and areas irrigated by the project's Right Bank main canal during commissioning. The water use observed during this period was compared with that forecast for the project at full development. From the limited data available, feasible targets for the phasing-in of land during commissioning are suggested, for use both by planners and managers. The effect of adopting these targets on project viability is also briefly discussed.
