Lake Nyasa, the third largest lake in Africa, is bordered by Tanzania in the north and northeast, by Mozambique in the east, and by Malawi in the south and west.
The lake is bounded by steep mountains, except in the south.
Its main tributary is the Ruhuhu River in the northeast; the Shire (in the south), a tributary of the Zambezi, is the lake's sole outlet.

 Lake Malawi - Wikipedia, the free encyclopedia
Lake Malawi, originally known as Lake Nyasa, Lake Nyassa and Lake Niassa after the Yao word for "lake" (officially, still called Niassa in Mozambique), is the most southerly lake in the Great African Rift Valley system.
The lake is about 560 km long and 75 km wide at its widest point, with a total area of approximately 29,600 sq km, and is bordered by Mozambique, Malawi, and Tanzania.
Although Portugal colonised the eastern shores of the lake, the islands of Likoma and Chizumulu which lie just off the shore were colonised by Scottish missionaries from Nyasaland, and as a result were incorporated as part of Nyasaland rather than Mozambique.

 CHILWA - LoveToKnow Article on CHILWA
(incorrectly SHIRWA), a shallow lake in south-east Africa, S.S.E. of Lake Nyasa, cut by 35 20 E., and lying between 15 and 15 35 S. The lake is undergoing a process of desiccation, and in some dry seasons (as in 1879 and 1903) the open water is reduced to a number of large pools.
Formerly the lake seems to have found an outlet northwards to the Lujenda branch of the Rovuma, but with the sinking of its level it is now separated from the Lujenda by a wooded ridge some 30 to 40 ft. above the surrounding plains.
The lake was discovered by David Livingstone in 1859 and was by him called Shirwa, from a mishearing of the native name.

She has determined also that although the water is clear, the lake is very deep and weakly stratified in the top 250 metres and that light is a significant factor affecting the growth of algae.

Given this scenario it is not surprising that the JLB Smith Institute of Ichthyology and Rhodes University are rising to meet the challenges with a variety of "freshwater projects" in South Africa and elsewhere in Africa.
The project on this lake was multifaceted in that threats to freshwater biodiversity comes from a) changes to the quality of the water which affect the ecosystem processes and can induce massive fish kills, and b) overfishing can also drive small populations of endemic fishes to extinction.
Not surprisingly, the quality of water in the lake is changing and the project had to make some strong recommendations regarding landuse practices and river management to slow the deterioration.
