Bulletin 2 September 2015

Based on the information available on 2 September, OPIDIN predicts that the flood in 2015 will be about as high as last year and not as high as in 2012 and 2013. The prediction of the flood level is not yet fully certain, but it has become very likely that the flood will be higher than in 2011 and lower than in 2007-2010.

2 September 2015

Based on the information available on 2 September, OPIDIN predicts that the flood in 2015 will be about as high as last year and not as high as in 2012 and 2013. The prediction of the flood level is not yet fully certain, but it has become very likely that the flood will be higher than in 2011 and lower than in 2007-2010.

The water level on the gauge of Mopti amounted to 478 cm on 2 September. The water level in Mopti will still increase with one meter until the peak is reached in Mopti between 14 and 18 October. The flood level will be at its maximum in Akka in the first half of November and in Diré in the second half of November. These predictions are based on the water level reached in Mopti on 2 September, but also takes into account the recent rainfall in the Upper Niger and Bani, with two rainy days during the last week (27 and 31 August).

There has fallen a lot of rain in Mali, and also in Senegal and Burkina Faso, during last August. The flooding of the Inner Niger Delta, however, mainly depends on the rainfall in the south-western part of Mali and in the eastern part of Guinee-Conakry, where the total rainfall was only a bit higher than what is normal for this time of the year. This explains why the flooding of the Inner Niger Delta will not be not as high as in 2012 and 2013, despite there was a lot of rain in, and around, the Inner Niger Delta.

OPIDIN predicts that the southwestern part of the Inner Niger Delta will become available for grazing cattle in the second half of November. Using the relationship between peak flood level in Mopti and the annual date when the cows are allowed to enter the Inner Niger Delta at Diafarabé, OPIDIN predicts that the cattle can cross the river at Diafarabé on about 15 - 20 November.
