Cuanza River

The Cuanza River, also known as the Kwanza, the Quanza, or the Coanza, is the longest river in Angola. It empties into the Atlantic Ocean just south of the national capital Luanda.

Geography

The river is navigable for about from its mouth, located south of Luanda. Its tributaries include the Cutato and Lucala.

The river's navigable lower course was the original route of the Portuguese invasion of northern Angola.
The Capanda Dam in Malanje Province was finished in 2004, providing hydroelectric power to the region and assisting in its irrigation. The Cambambe Dam and the Lauca Dam were also constructed on the river. The Caculo Cabaça Dam is under construction with estimated completion in 2024. The Barra do Kwanza, the mouth of the river, is gradually being developed for tourism, including a golf course.

Rich biodiversity has been found in the Angolan river, according to research reported on the Science and Development Network website. Angola's first biodiversity tally of the Cuanza River has so far found 50 fish species. Researchers from the National Fishing Research Institute and the South African Institute for Aquatic Biodiversity say genetic testing may reveal new species. Sportfishing includes tarpon.

Angola's currency, the kwanza, is named after the river. The river is also the namesake of the provinces of Cuanza Norte and Cuanza Sul.
