Arumugam (1957) outlined a simple method of determining the spill dimensions of a village irrigation tank. A study was carried out to see if the ancient tank builders have followed this method and the very high correlation coefficients (> 0.91) suggest that these builders may have known the method proposed by Arumugam. Of course the study could be carried out only in the case of 8 tanks where the relevant data are available. The correlations are not that strong when these tanks were restored as now modern methods of designing a spill is available.
