The Ogooué (or Ogowe), also known as the Nazareth river, some 1,200 kilometres (750 mi) long, is the principal river of Gabon in west central Africa and the fifth largest river in Africa by volume of discharge, trailing only the Congo, Kasai, Niger and Zambezi. Its watershed drains nearly the entire country of Gabon, with some tributaries reaching into the Republic of the Congo, Cameroon, and Equatorial Guinea.[2]

Course

The source of the Ogooué River was discovered in 1894 by Mary Kingsley, an English explorer who travelled up the banks by steamboat and canoe.^{[citation needed]} The river rises in the northwest of the Bateke Plateaux near Kengue, Republic of Congo.[2] It runs northwest, and enters Gabon near Boumango. Poubara Falls are near Maulongo. From Lastoursville up to Ndjole, the Ogooué is non-navigable due to rapids. From the latter city, it runs west, and enters the Gulf of Guinea near Ozouri, south of Port Gentil. The Ogowe Delta is quite large, about 100 km long and 100 km wide.

Basin

The Ogooué Basin is 223,856 square kilometres (86,000 sq mi), of which 173,000 square kilometres (67,000 sq mi) or 73 percent lies within Gabon. It mostly consists of undisturbed rainforest with some savanna grassland where the mid-year dry season is longest. It is home to a high biodiversity. All three species of African crocodile, for instance, occur in the river: the Nile crocodile, the dwarf crocodile, and the slender-snouted crocodile. It is also the type locality for the catfish Synodontis acanthoperca.[3]

The Mpassa River is a tributary of the Ogooué River. The Ndjoumou River is the main tributary of Mpassa River.

Economy

The Ogooué is navigable from Ndjole to the sea. It is used to bring wood to the Port Gentil Harbour.

The Ogowe Basin includes several major conservation reserves, including Lope National Park.

The catchment area has an average population density of 4 people per km². Towns along the river include Ayem, Adané, Loanda, Lambaréné, Ndjole, Booué, Kankan, Maulongo, Mboungou-Mbadouma, Ndoro, Lastoursville, Moanda, and Franceville near the Congo border.

Towns in Congo include Zanaga.

The first European explorer to trace the river to its source was Pierre Savorgnan de Brazza, who traveled in the area in the 1870s.[2]

• Abanga, which rises in the Cristal Mountains, near Medouneu
