Situated in the Ashanti region of Ghana, Lake Bosomtwe is one of six meteoritic lakes in the world. Lake Bosomtwe and its environs, in the Ashanti Region, are located about 33 km southeast of Kumasi in the Northern tip of the Adansi mountains in the forest zone of Ghana. 

The southernmost section of the site overlaps the northern section of the Bosomtwe Range Forest Reserve creating a combination of forest, wetland and mountain ecosystems. The lake exhibits a radial drainage system of 106 km2, a maximum depth of 78m and a diameter of about 11km at its widest part. 

The site is home to a great diversity of wildlife and a human population of over 50,000 inhabitants whose main economic activities are farming, fishing and tourism, as the lake is a major national tourist destination.

Some institutions involved with the management of the Lake Bosomtwe Biosphere Reserve (LBBR)

CREMA Committee

The CREMA system is where local communities are involved in the management of a natural resource within their communities.
The CREMA Committee therefore manages the natural resource using a management plan which is a manual which serves as a guide for the use and control of resources within protected areas.
The Lake Bosomtwe CREMA Committee therefore uses the Lake Bosomtwe Community Resource Management Area Management Plan created by the MAB Committee through the UNESCO Man and the Biosphere programme under the Sustainable Management of Lake Bosomtwe Project for the development of its activities and management actions within the CREMA

WRC (Water Resources Commission)

The Water Resources Commission (WRC) was established by an Act of Parliament (Act 522 of 1996) as the institution responsible for the management of Ghana’s fresh water resources. 

It is specifically mandated to regulate and manage the water resources and to co-ordinate related government policies. One avenue through which the Commission carries out this mandate is by the Basin Secretariats which are dispersed throughout parts of the country. There are six (6) Basin Secretariats namely; the Densu, White Volta, Ankobra, Pra, Tano and the Black Volta Basin Secretariats. The Pra Basin is the fourth priority basin that the Water Resources Commission has established as a decentralized management body to facilitate the implementation of Integrated Water Resources Management (IWRM). 

The Pra Basin Secretariat has oversight responsibility for managing the Lake Bosomtwe Biosphere Reserve since it falls within the basin’s catchment area.
