Monthly Hydrological Bulletin: Septembre 2020

The month of September was characterized by continued flooding in the Inner Delta and Lower Niger. However, there is a beginning of the recession in the Upper Niger and Middle Niger sub-basins, thus marking the beginning of the end of the rainy season. The peak flow of the exceptional local flood at the Niamey hydrometric station was the cause of serious flooding with loss of human lives and very significant damage. This was the highest flow ever recorded in Niamey since observations began in 1929
