the city during the colonial period, "Moundou-la-Rouge". In 1926 the Cotton Company of the Congo installed a ginning factory in Moundou. The cotton company later became Cotonfran in 1928 and then CotonTchad in 1972. The first cadastral map of the town of Moundou was manufactured on 2 February 1926. Since there were not, at the time, the materials for substantial topographical surveys, the drainage pipeline of the town was facing the river in the belief that the natural inclination would head toward the river, when in reality the river level is higher than the level of the city. In 2012, the mayor of Moundou, Laoukein Kourayo Médard, said that "every time there was a flood, all the waters of the Logone discharged to Lake Wey (in the West), which in turn sprays its water into the city, flooding Moundou entirely."
