The Sankarani is a river in West Africa and one of the major tributaries of the Niger River. Its sources are located in the southeastern highlands of Guinea, and it flows northward until it joins the Niger in Mali.
The river forms part of the right-bank drainage system of the Niger. It marks a portion of the border between Guinea and Mali, then enters southern Mali. Its water flow depends on rainfall in the Sudano-Guinean zone during the summer season, which means the river's water level varies significantly from year to year.
Geography and water flow
The Sankarani begins in hilly terrain with heavy rainfall, then flows through broad valleys. Its drainage basin is said to be part of the larger Niger River system. Many small tributaries join it along its course.
The Sélingué Dam
The Sankarani is most notable for the Sélingué Dam in Mali, constructed in the 1970s. The dam created a large reservoir and serves two purposes: hydroelectric power generation and management of downstream water flow. Power generated at the dam contributes to Mali's national electricity grid.
The reservoir has also enabled fishing and irrigated agriculture on which local populations depend. Construction of the dam required the relocation of large numbers of people from areas that became submerged, which affected local land-use practices.
Economy and environment
Communities along the Sankarani rely on farming, fishing, and herding. The region also has mining operations, particularly for gold, which has raised water quality concerns. Changes in water flow resulting from dam management affect aquatic life and farming along the river's banks.
