INTRODUCTION

The hydrological situation in the Niger basin during the month of July 2017 was characterized by the continuous increase in flow as a result of progressive installation of rainy season.

The filling of Selingue Dam in Mali has started on the 6th of July 2017 and that of Kainji Dam in Nigeria on the 18th of June 2017.

The flow analysis situation was carried out on the four sub-catchments basin using the data recorded from the reference gauging stations which are: Upper Niger at Koulikoro (Mali), Inland Delta at Dire (Mali), Middle Niger in Niamey (Niger) and Lower Niger at Lokoja (Nigeria) as shown in figure 1.

Figures 2 to 5 show the comparative hydrographs for hydrological years 2017/2018, 2016/2017, 2015/2016 and 2012/2013 as well as the five-year wet return period and the statistical mean at the references stations.

Figures 6 and 7 show the level of the reservoirs water at Selingue Dam in Mali and Kainji Dam in Nigeria.
