Using well-designed sample, anecdotal evidence from farmers of a recently completed irrigation and drainage project in Bhawalnagar Pakistan, valuable impact indicators could be assessed. The case study suggests that although this simple and quick method is not a substitute for the detailed scientific survey, yet it can be handy, sufficient, and could be usefully used at a nominal cost as a supplementary method. The parameters approached were the depth to water-table, crop yields, cropping pattern, abandoned lands, water distribution, and seepage reduction, etc. The results showed that some of these, including the depth to water-table, seepage reduction, and cropping pattern compared well with previous technical studies, while some others did not. The physical interventions of the project under quick evaluation comprised concrete lining of about 170 kms of the distributary canals and 352 kms of surface drains. The paper concludes that the farmers’ perceptions, when carefully designed and analysed, offer substantial feedback for remedial actions and for planning future projects.
