The roundest lake in the world is Lake Bosumtwi, located about 30 kilometers southeast of Kumasi in the crystalline bedrock of the West African Shield. The lake is famous for its unique circular shape. Lake Bosumtwi is the only natural lake in Ghana. According to scientists, the lake was formed about 1.07 million years ago by the impact of a large meteorite. This impact created a 10.5-kilometer-wide crater on the surface, which eventually filled with water over time, forming the present-day Lake Bosumtwi.
The shape of Lake Bosumtwi is very close to a perfect circle, and the surrounding area is smooth and rounded as if it were drawn by nature with a compass. The entire lake covers an area of about 49 square kilometers, with a water depth of about 70 to 73 meters. The lake forms a conical structure as it slopes downward around the edges, adding to its unique charm.
Environmentally, Lake Bosumtwi is surrounded by dense rainforest, which brings a rich and diverse ecosystem to the lake. The vegetation around the lake is also very lush, providing more habitats and food sources for local wildlife. Thus, the lake is a favorite breeding ground for many bird species, attracting bird enthusiasts from around the world to observe the birds’ breeding activities.
