The Niger River takes its source in the mountains of Fouta-Djalon in Guinea and crosses successively Mali, Niger, Benin and Nigeria where it’s ended into the Atlantic Ocean after crossing approximately 4200 km. It is the third longer river of Africa, 14th of the world and 9th from the point of view of the size of its catchment area. Its active basin covers a surface of approximately 1,5 million km 2  shared by  nine (9) countries gathered within the Niger Basin Authority (NBA), these are :  Benin, Burkina Faso, Cameroun, Cîte d'ivoire, Guinea, Mali, Niger, Nigeria and Chad. The major tributary Benue takes its source in Chad before crossing Cameroun to join the River Niger at Lokoja in Nigeria.

The hydrological year of the Niger River starts on June 1st and ends on May 31st of the following year.  

This hydrological assessment of the Niger River for this 2014/2015 hydrological year state the flow analysis at the representative stations of the basin: Koulikoro (in Mali) for the Upper Niger, Dire for the Inland Delta (in Mali); Niamey for the Middle Niger (in Niger) and Lokoja for Lower Niger (in Nigeria).

Flows monitoring during this 2014-2015 hydrological year was carried out within the framework of the IWRM2/Niger-HYCOS project activities from over hundred  hydrometric stations equipped with data collection platforms (DCP)  Satlink type, some electronic Liminigraphs GSM transmission, BLU radio or simple  Gage plates scales followed by gage readers which transmit data to the national hydrological  services (NHS) and Project Regional Center by GSM, Internet and other classical means of data collection.

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)
