Bakoye ( Mande for "White River"; also Bakoyé and Bakoy ) is a river in West Africa . It flows through Guinea and Mali . At Bafoulabé in southwest Mali, in the Kayes region , it merges with the Bafing and becomes Senegal .

course

The river rises at an altitude of 760 meters from the Monts Ménien mountain in the north-west of Siguiri (Guinea). It flows north and forms part of the natural border between Guinea and Mali. It then meanders through the Manding Plateau and runs parallel to the Baoulé , which rises to the west of Bamako . The two rivers merge and then flow together with the Bafing at Bafoulabé to Senegal.

The Bakoye is a total of 560 km long and has a catchment area of ​​85,600 km³.

Hydrometry

The Bakoye has the most water in September, when the West African monsoons have just started. There is almost no water in January and June. The West African monsoons and their changing intensity have a major impact on the river system. In the dry period of 1972, a mere 30 m³ / s were measured at the measuring station in Oualia (about 70 km from the estuary), while in 1958 the discharge was 260 m³ / s. The average runoff in the period from 1951 to 1978 was 156 m³ / s. The annual flow averaged 4.9 km³. At the mouth of the river in Bafoulabé, the Bakoye accounts for a third to half of the discharge.

The average monthly flow of the Bakoye measured at the hydrological station at Oualia in m³ / s (1951–1990).
