Lake Bosumtwi

Lake Bosomtwe, also spelled Bosumtwi, is the only natural lake in Ghana. It is situated within an ancient impact crater that is about 10.5 kilometres (6.5 mi) in diameter. It is about 30 km (19 mi) south-east of Kumasi, the capital of Ashanti, and is a popular recreational area.

Lake Bosomtwe, located in the Bosomtwe District of the Ashanti Region, is facing increasing ecological pressure as encroachers reportedly clear vegetation along its fragile shoreline. The development has raised concerns among authorities, traditional leaders, and residents over the lake's ecological sustainability.

Lake Bosumtwi, a bowl-shaped body of water southeast of the fast-growing city of Kumasi, spans 49 square kilometers (19 square miles) and plunges to a depth of 70 meters (240 feet).

It is believed to be the result of meteoritic action about 1 million years ago, when a crater formed by the impact of an asteroid gradually filled with rainwater. It is the only natural lake in Ghana and one of six major meteoritic lakes in the world and is thus considered a unique national resource.
