Lake Malawi, alternatively called Lake Niassa or Lake Nyasa, is an African great lake.In the Eastern Africa Rift System, it is the southernmost lake, and Malawi, Mozambique, and Tanzania are the three countries that share it. It is the ninth-largest lake by size, Africa’s second-deepest and third-largest lake, and the fifth-biggest freshwater lake in the world by volume.The Government of Mozambique designated a segment of the lake as a reserve in 2011, while Lake Malawi National Park encompasses a chunk of the lake in Malawi. Nyasaland was the name of the area before Malawi was declared independent in 1964. Therefore, Lake Nyasa is the name given to the lake by Mozambique and Tanzania. Likoma Island and Chizumulu Island are the only inhabited islands on the lake, and the bigger island is Likoma Island.In 1984, the Lake Malawi National Park was listed as a UNESCO World Heritage Site. Shire River, which is the biggest and largest river in Malawi, is the primary outflow at the southern end, and the Ruhuhu River is the primary inflow of Lake Malawi. Malawi is an African Great Lake that is the third-largest lake in the world. The lake, which is situated in a significant depression in the north-central section, is 2,316 ft (706 m) deep at its deepest point (below sea level).One of the fun facts about Lake Malawi is that it has more fish varieties than just about any other lake, comprising a minimum of 700 cichlid fish. Commercial fisheries, focused mostly on the freshwater tilapia, have been built on this African Great lake’s southern end, and the Mwaya Beach is located near Monkey Bay on Cape Maclear. One of the world’s richest plant varieties can be found in Lake Malawi, with several varieties limited to the Malawian section of the lake. Several orchids, including Angraecum umbrosum, Habenaria livingstoniana, and Aerangis distincta, are among the 50 endemic plant varieties. The Mulanje Cedar is one of the several indigenous plants found on Mount Mulanje.Tourists can visit Lake Malawi because it is less crowded, has friendly local inhabitants, and offers many scenic viewpoints including the Lake Malawi National Park. Lake Malawi, more particularly the Lake Malawi National Park, is just 131 mi (212 km) from Lilongwe.If you want to read some fun facts about Lake Malawi, one of the great lakes of Africa, you should read further to know about it in detail. There is a lot of information available on Malawi Lake and its beautiful waters.The Geological History Of Lake MalawiWant to know about one of the great lakes? Its geological history is rich and will keep you intrigued, so keep reading! Malawi is an old lake and one of the main Rift Valley lakes, and is situated in a valley created by the East African Rift, splitting the African tectonic plate in two, known as a diverging plate-tectonics border. Malawi had been thought to be one to two million years old, but new evidence suggests a much older lake, with a basin that formed 8.6 million years ago and in-depth water conditions that first developed 4.5 million years ago. Water levels have fluctuated drastically throughout time, ranging from more than 1968 ft (600 m) below present lake levels to 33–66 ft (10–20 m) above current levels.The lake dried up nearly entirely at times, leaving just one or two tiny, very alkaline and salty lakes in what is now Malawi’s lowest portions, during droughts. Around 60,000 years ago, Lake Malawi’s water chemistry resembled that of today. Major low-water episodes are thought to have happened millions of years ago (when they may have totally dried up), and it may have been 390-490 ft (120–150 m) below present water levels at the height of the low-water era between 1390 and 1860 AD.Water Characteristics Of Lake MalawiSo what is the water in Malawi like? Aren’t you curious?The water in the lake region is warm and alkaline, with a pH range of 7.7 to 8.6. One of the amazing great lakes of Africa, Malawi Lake has a surface temperature of 75– 84 F (24– 29 C) and deep parts of around 22 C (72 F). The thermocline lies 130–330 ft (40–100 m) below the surface. At a depth of around 820 ft (250 m), the oxygen limit is reached, essentially limiting native species of fish and other aerobic sealife to the top section. The water is unusually clean for a lake, with visibility up to 66 ft (20 m). However, visibility is usually less than half that, and it is below 10 ft (3 m) in muddy bays. However, the waters are murkier during the precipitating season due to more debris and mud in the river.The Discovery Of Lake MalawiSo how was Malawi discovered? What is the secret story behind it?Candido Jose da Costa Cardoso, a Portuguese trader, was the first European to explore the lake in 1846. In 1859, David Livingstone arrived at the lake and gave it the name Lake Nyasa; Lake of Stars and Lake of Storms were two of his nicknames for the lake. The name ‘Lake of Stars’ originates from Livingstone’s observation of lights from fishermen’s lanterns on their boats in Malawi, which resembled stars in the sky from a distance. He later referred to the region as the Lake of Storms after witnessing the unexpected severe gales that swept across the area.On August 16, 1914, Captain Rhoades’ British boat got directives from the British Empire’s high authority to ‘sink, burn, or destroy’ the German Empire’s only armed boat on the lake, namely the ‘Hermann von Wissmann’, which the captain commanded. In Germany’s East African territorial region, Rhoades’ crew located the ‘Hermann von Wissmann’ in a port near Sphinxhaven. British boat ‘Gwendolen’ disabled the German vessel with a single cannon discharge fired from around 1,968 yds (1,800 m). This brief naval battle was hailed as the British Empire’s foremost maritime victory of World War I by ‘The Times’ in Britain.Borders Of Lake MalawiWhat borders does Malawi share? Where is it situated?The lake’s surface area is divided between Malawi and Tanzania, which is a point of contention. The international boundary, according to Tanzania, extends right across the center of the lake. On the other hand, Malawi claims the entire area of the lake, which is not in Mozambique, including the area next to Tanzania’s coastline. Both parties point to the 1890 Heligoland Treaty, which established the spheres of influence between Great Britain and Germany. The squabble in this issue arose when the British colonial authority, shortly after capturing Lake Tanganyika from Germany, placed all of the lake’s waters under one jurisdiction, Nyasaland, with no distinct administration for the Tanganyikan section of the surface. Two jurisdictions were formed later in colonial times. The disagreement became official in 1967 when Tanzania filed a formal complaint against Malawi; nevertheless, no resolution was reached.There were sporadic flare-ups of warfare during the ’90s and the 21st century. Lake Malawi’s oil-drilling project in 2012 drew attention to the problem, with Tanzania urging that development be halted until the disagreement was resolved. The British and Portuguese struck an agreement in 1954 that designated the center of the lake as their border, with the exception of the two inhabited islands of Likoma Island and Chizumulu Island, which were retained by the British and are now a territory of Malawi.Wildlife Surrounding Lake MalawiMonkeys, hippopotamus, Nile crocodiles, and a large number of Africa’s fish eagles that forage on the lake’s fish species can all be discovered in and around Lake Nyasa or Malawi. Because its waters are abundant in fish, Lake Malawi has supplied a significant food supply for the local people of its coasts for millennia. The four species of chambo, which can be any of four species of the subgenus Nyasalapia (O. squamipinnis, O. saka, O. lidole, and Oreochromis karongae), as well as the closely related O. shiranus, are among the most popular fish. The Engraulicypris sardella (Lake Malawi sardine) and the huge kampango catfish are two more species of fish that sustain substantial fisheries (Bagrus meridionalis). The majority of fishing is used to feed the growing human population surrounding the lake, although some is exported from Malawi. Overfishing and water pollution are putting the wild fish population in jeopardy. Another hazard is a reduction in the lake’s water level, which is caused by water extraction by an expanding human population, deforestation, and climate change.Lake Malawi is known for hosting adaptive radiation in various animal species, most notably large cichlid fish. Lake Malawi is home to at least 700 cichlid species, with other estimates putting the number as high as 1,000. Because of the large number of undescribed fish species and the great variance among certain species, defining them is a difficult undertaking. Nevertheless, cichlids from Lake Malawi are as important to science as the honeycreepers from Hawaii or the finches from the Galapagos Islands of Charles Darwin. All cichlid fish in the lake are indigenous to the Malawi system, which includes the neighboring upper Shire River and the smaller Lake Malombe, with the exception of four species (Serranochromis robustus, Oreochromis shiranus, Coptodon rendalli, and Astatotilapia calliptera). The majority of Malawi cichlid fish, including the mbuna species, are found in shallow coastal areas. However, diplotaxodon has been discovered down to depths of 660 ft – 720 ft (200 m –220 m), and many species (particularly Copadichromis quadrimaculatus, Rhamphochromis, and Diplotaxodon) have been found in pelagic seas. The lake’s cichlid fish are separated into two categories, with haplochromines accounting for the great majority of species. Malawi haplochromines are mouthbrooders, although their general behavior and ecology differ greatly. Cichlids make up the great bulk of the lake’s fish species. In addition, several species of mochokid catfish (Anguilla nebulosa, Malawi and chiloglanis (known to Europeans as the squeaker), Synodontis njassae, cyprinids (in the genera Opsaridium, Labeo, and Barbus, along with air-breathing catfish (Clarias and Bathyclarias as well as the Kampango bagrus meridionalis), and Lake Malawi sardine) are also found along with the widest point of the lake.The majority of them are found across Africa as a genus, while Bathyclarias is unique to the lake. There are 28 freshwater snail species (including 16 native and nine bivalves) in Lake Malawi (two endemics, unionid Nyassunio nyassaensis, and the Aspatharia subreniformis). Unlike Lake Tanganyika, which has a plethora of indigenous freshwater crabs and shrimp, Lake Malawi has just a handful. The solitary crab in the lake is the Malawi blue crab, which is not indigenous. Although the atyid shrimp Caridina malawensis is native to the lake, it is little recognized and has been mistaken for C. nilotica, which is not present there. Two cladocerans (Bosmina longirostris and Diaphanosoma excisum), three copepods (Mesocyclops aequatorialis, Thermocyclops neglectus, and Tropodiaptomus cunningtoni), and many ostracods are among the pelagic zooplanktonic species. Lake Malawi is known for its massive swarms of Chaoborus edulis, small, harmless lake flies. These swarms, which appear far out over the water and may be mistaken for plumes of smoke, were seen by David Livingstone on his visit to the lake.
