The Selingue reservoir is situated in the Sankarani valley, 150 km south of Bamako in Guinean climate zone with rainfall of about 1200 mm/year. The reservoir supplied at annual scale, reached its maximum in November after rain seasons and its minimum at may June before the next rainfall season. This lake has a 2135 million m3 volume (29% of the average inflow) and a surface of 450 km2 for a water level of 349 m above mean sea level. Initially intended for the energy production the reservoir allows the production of fish in the lake and the support of irrigation in its downstream part. Fishing and irrigation with Selingue contribute for an important part to the development of national economy and food security. It provides incomes to the fishermen and to farmers and creates jobs.
Water surface according to SOPT5 NDWI images at decay scale is linked to reservoir volume, water requirement and hydro climatic data (rainfall, temperature).
Desegregation method is utilized to downscale the precipitation and temperature data from MCG scale to regional scale, which is then used as input in a model to project the change of water supply both in surface, volume and it impact on hydropower, fish production and irrigation water availability by 2020 and 2050.
