description Lake Chilwa Overview
Lake Chilwa is a shallow, endorheic lake located primarily in southern Malawi, with its basin extending into neighboring Mozambique. It is the second-largest lake in Malawi by surface area and varies dramatically in size and salinity due to seasonal rainfall patterns and periodic drying cycles. The lake and its surrounding wetlands support one of Malawi's most productive inland fisheries, sustaining local livelihoods, and the ecosystem is designated as a Ramsar Wetland of International Importance, reflecting its value for biodiversity and migratory bird populations.
help Lake Chilwa FAQ
Where is Lake Chilwa?
Lake Chilwa is located mainly in southern Malawi, close to the border with Mozambique. Its wider basin extends into neighboring Mozambique.
Why does Lake Chilwa change size so much?
Lake Chilwa is shallow and endorheic, meaning it has no normal outlet to the sea. Seasonal rainfall can therefore change its water level, surface area, and salinity dramatically.
Is Lake Chilwa Malawi's largest lake?
Lake Chilwa is the second-largest lake in Malawi by surface area. Lake Malawi, also known as Lake Nyasa, is larger.
What makes Lake Chilwa different from an ordinary freshwater lake?
Its shallow basin and lack of an outlet make Lake Chilwa highly sensitive to rainfall and evaporation. Parts of the lake can become more saline as water levels fall, especially during dry periods.
