Monthly Hydrological Bulletin. MAY 2015

INTRODCUTION

The month of May 2015 marked the end of the hydrological year 2014/2015 which started in June 2014 in the Niger River basin. The hydrological year 2014/2015 ended in May 2015 with low flow situation observed at the entire Niger River basin. The flows were supported during this period of recession by the releases of dams Sélingué in Mali, Lagdo Cameroon, Kainji, Jebba and Shiroro Nigeria.

The flow analysis situation was carried out by dividing the basin into four sub‐catchments also represented with reference gauging stations as follows: 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.
