425mm of rain fell on 24 and 25 January 1981 causing the Buffalo River that flows North-south through the town to burst its banks. The average rainfall was 175mm. The force of the water was so immense that victims' bodies were found as far away as Mossel Bay. Ten of the survivors were rescued 21km away at the Floriskraal Dam. Outside relief teams only reached Laingsburg 24 hours later as all the bridges leading to the town were blocked.
A fund of R3 million was collected by the Die Burger newspaper for victims of the flood. The state spent R7 million repairing the infrastructure and constructing 118 houses, a commercial center, a sports complex and a boarding school. There were allegations that victims of the flood had been buried in a mass grave. This was investigated by the Provincial government of the Western Cape. The archeological investigation proved conclusively that there was no evidence to back the allegations.
