LAKES, RIVERS, LAGOONS
Ghana is drained by a large number of streams and rivers. The country's major feature is Volta Lake, the largest man-made lake on earth (by surface area). The lake begins in the center of the country at the confluence of the Black Volta and the White Volta rivers. Two other major tributaries of Volta Lake are the Oti and Afram rivers.
Other important rivers are, from west to east, the Tano, Ankobra, Pra, Birim and Densu rivers, which all flow into the Gulf of Guinea. All are scenic and cultural destinations where a canoe ride would be easy to obtain, but only the Pra River has a developed tourism infrastructure, offering rafting and whitewater excursions.
There are also a number of coastal lagoons, which are home to many Ramsar birding sites, including the extensive Keta lagoon formed by a long coastal sandbar. South of Kumasi is Ghana's only natural lake, the unique Lake Bosumtwi, Africa's largest meteorite impact lake.
