Konkouré River

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

Geography

The river originates in the Futa Jallon highland region and flows in a westerly direction to the Atlantic Ocean north of the Baie de Sangareya at 9°46'N, 14°19'W. The Kakrima River is its major tributary. The river delta covers. Vessels of up to draft can navigate upstream to Konkouré; beyond that point, there are rapids.

Environment

The upper river flows over a rocky substrate with many rapids and waterfalls, making it unsuitable for navigation, though it does make it suitable for electricity production. The lower river is a shallow, funnel-shaped, mesotidal, mangrove-fringed, tide-dominated estuary. Rice farms have been established in the mangrove areas of the delta "with some success".

Wildlife

The river is home to 96 recorded freshwater fish species.
The estuary, along with part of Sangareya Bay and the mouths of the Konkouré and Bouramaya rivers, has been designated an Important Bird Area by BirdLife International because it supports significant populations of western reef egrets, pied avocets and common redshanks. It encompasses 28,000 ha of mangroves, mudflats, sandbanks and rice-fields. African manatees occur in the mangroves and common bottlenose dolphins in the bay.

Dams

In 1999, the Garafiri Dam was opened at a cost of $221 million; it can produce of electricity. Construction of a hydroelectric dam on the river near Kaleta, the Kaleta Hydropower Plant, was completed in June 2015 and commissioned on 28 September at a cost of $526 million; the dam lies about or north of the capital city of Conakry.
In 2015, the central government contracted with Chinese firms to begin building a dam, near Souapiti, about further upstream, which would almost double Guinea's power generation output at an estimated cost of $2 billion. This would, however, require that 15,000 people move out of what would become a flood plain.
