Konkouré River

The Konkouré River arises in west-central Guinea and flows into the Atlantic Ocean.^[1] Several dams on the river provide the country with much of its electricity.

The river originates in the Futa Jallon highland region and flows in a westerly direction 303 kilometres (188 mi) to the Atlantic Ocean north of the Baie de Sangareya (Sangareya Bay)^[1] at 9°46'N, 14°19'W.^[2] The Kakrima River is its major tributary.^[2] The river delta covers 320 square kilometres (120 sq mi).^[3] The "Lower Konkouré is a shallow, funnel shaped, mesotidal, mangrove-fringed, tide dominated estuary".^[4] Rice farms have been established in the mangrove areas of the delta "with some success".^[5]

In 1999, the Garafiri Dam was opened at a cost of $221 million; it can produce 75 megawatts (101,000 hp) of electricity.^[1] Construction of a 240-megawatt (320,000 hp) hydroelectric dam on the river near Kaléta [fr] was completed in June 2015 and commissioned on 28 September at a cost of $526 million;^[6] the 1,545-metre-long (5,069 ft) dam lies about 120 kilometres (75 mi)^[7] or 85 miles (137 km)^[6] north of the capital city of Conakry.^[7] In 2015, the central government contracted with Chinese firms to begin building a 550-megawatt (740,000 hp) dam (the Souapiti Hydropower Station), near Souapiti, about 2 kilometres (1.2 mi) further upstream,^[7] which would almost double Guinea's power generation output at an estimated cost of $2 billion.^[8][9] This would, however, require that 15,000 people move out of what would become a flood plain.^[7]

The river is home to 96 recorded freshwater fish species.^[10]

Vessels of up to 3 metres (9.8 ft) draft can navigate upstream to Konkouré; beyond that point, there are rapids.^[11]
