Location of the watershed
The catchment in Cameroon is the upper part of the Mefou River in the Centre Region of Cameroon (Région du Centre) at the city boundary to Yaoundé, the Capital of the country, at the bridge to the rural area. One third of the localities within the watershed is part of the urban area of Yaoundé since the urbanization is processing (Map 1). The proximity to the urban parts of Yaoundé is of great importance for the watershed, since it comprise a dam constructed to provide fresh water to the city. The watershed covers parts of the Yaoundé subdivision (arrondissement) in the Mfoundi Division (départment) and parts of the Okola and Lobo subdivision in the Lékié division.
The surface area of the water is around 70 km2 and includes around 20 villages and hamlets of different size.
The climate of the watershed is a tropical wet-and-dry climate, with around 1600 mm of rain per year and two pronounced wet seasons. The ferralitic soils in the catchment are mostly covered with a dense humid forest; but progressively, agriculture around the villages and urbanization are leading to land cover change. The rocks are dominantly gneiss.
Access to water
Natural springs, rivers, scattered wells and water pumps are the sources for drinking water access. In the rural areas in general as well as in the urban parts, pipeline systems are missing.
A special characteristic of the watershed is a dam, constructed from 1969 to 1971 which supplied Yaundé with freshwater till 1999. Since the supply of Yaoundé with drinking water is not sufficient (100 000 m³ per day instead of 250 000 m³), the government decided to reconstruct the dam in 2012. The re-activation of the dam is planned for the beginning of 2014. The national water company of Cameroon, CamWater, is running the construction.
