The Sonfon Lake ( English Lake Sonfon ) is a lake in the Koinadugu district in Sierra Leone , West Africa . It is located in the hills of the Sula Mountains at an altitude of 549  m , around 60 kilometers south of the city of Kabala . The lake is a nature reserve .

description

The lake has a maximum depth of six meters and is one of the largest lakes in the country with an area of ​​2.6 square kilometers. It is fed by seven small tributaries. The annual rainfall in the region is between 2286 mm and 2540 mm. During the rainy season, the water level in the lake rises significantly and floods a much larger area.

The outflow is via the Pampana at the southern end , which flows into the Atlantic Ocean via the Sherbro . In the dry season the lake is completely covered with vegetation. The hilly environment consists of grassland and forests. Around 115 species of birds were recorded in the lake area and the surrounding vegetation during the IBA survey in 1994, including the rare Schillerglanzstar ( Coccycolius iris , English Emerald Starling = "Smaragdstar"). Herons and egrets are widely used in the marine environment.

Gold mining

Gold deposits have been known in the sea area since 1926. At times up to 15,000 miners are said to have been active around the lake and the tributary areas. In 1994, the gold content of the alluvial material in six tributary areas was given as 14.27 grams per ton of excavation. The nature conservation authorities made this degradation responsible for the lowering of the water level.
