The Konkouré River arises in west-central Guinea and flows into the Atlantic Ocean. at 9°46'N, 14°19'W. The Kakrima River is its major tributary. 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 (IBA) 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
