 Another source states that the dam was constructed of concrete and gives a figure of 152 feet height of the full water level of the reservoir, with impounding capacity of 10.56 thousand million cubic feet along with a total estimated cost of 84.71 lak.The construction involved the use of troops from the 1st and 4th battalions of the Madras Pioneers as well as Portuguese carpenters from Cochin who were employed in the construction of the coffer-dams and other structures.The greatest challenge was the diversion of the river so that lower portions of the great dam could be built.
