Embark on a journey to Lake Victoria, Africa's largest and most majestic lake. Nestled right at the equator in Africa lies Lake Victoria. It’s so vast that it feels more like a sea than a lake. Not only is it the largest lake in Africa, but it’s also the world's second-largest fresh water lake by surface area after Lake Superior in North America.
In terms of volume, Lake Victoria is the world's ninth-largest continental lake, containing about 2,424 km3 of water. Interestingly, both lakes share a commonality. Each is part of a group of so-called Great Lakes. Now we’ll delve deeper into these and other known facts from the history of this great lake.

To the east of the lake lies the famous ecosystem known to the world for the Great Migration of animals: the adjacent Serengeti National Park and the Maasai Mara National Reserve. There are other protected areas nearby, and directly within its bounds are several island national parks.
The Victoria Lake region is one of Africa's most populated. Including its entire basin and tributaries, over 40 million people live here. This includes neighboring Burundi and Rwanda. The area is overcrowded, and the strain on the lake is increasing. Later we will learn more about the consequences of that.
Size of the Lake and Other Characteristics
Now let's begin to understand the size and significance of Lake Victoria. We will also attempt to understand its ecosystem and natural wonders. To do so we must first look at some key numbers. These describe the area, average and maximum depth, water volume, and so on.
What is Lake Victoria's Surface Area?
The lake's surface area is 68,800 km² (26,600 sq mi). It could fit Lithuania or two Belgiums. Imagine that! The lake is 320 kilometers (199 miles) long. At its widest, it measures 275 kilometers (171 miles). Its shape resembles an irregular quadrilateral. The shoreline stretches an impressive 4,828 kilometers (3,000 miles). A shoreline walk around the lake takes you about 40 days!
Lake Victoria Depth
The average depth of Lake Victoria is 40 meters (131 feet). The maximum depth is 84 meters (276 feet). This is relatively shallow compared to nearby Lake Tanganyika. That lake reaches impressive depths of 1,471 meters (4,826 feet). Lake Victoria contains 2,750 cubic kilometers (659 cubic miles) of water.

This places it ninth worldwide. Its vast area, rather than depth, accounts for this. Some might be surprised that several of the world's most impressive lakes are located in Africa, but this beautiful continent is full of amazing surprises!
Inflows and Outflows
What feeds it? Lake Victoria receives about 80% of its water directly from rain. The remaining 20% comes from rivers flowing in. The largest is the Kagera River. It flows in from the west, starting in Burundi. While Lake Victoria is technically the Nile's source, the Kagera River plays this role in reality.
More precisely, the Nyabarongo or Ruvubu Rivers should be called the Nile's source. These are tributaries of the Kagera. It's unclear which river is more crucial for the Kagera and hence, the river Nile basin.
What other rivers bring water to the lake? These include Kenya's Nzoia, Yala, Nyando, Sondu Miriu, and Gucha. Tanzania's Mara River and others also contribute. In total, 17 rivers and many unnamed streams flow into Lake Victoria.
The small eastern rivers, mainly from Kenya, bring in more water than the large Kagera from the west. The only river leaving Lake Victoria is the Victoria Nile. It is a section of the White Nile - the Nile River's longest branch.

The Victoria Nile flows north from the south. It rushes towards Lake Albert, another of the African Great Lakes. Along the way, it goes through numerous waterfalls. Notably, the river is used for hydroelectric power generation. The fast-moving river calms after crossing the Kyoga lakes cluster. These are often considered one single lake. Past these, the river gets the name the Kyoga Nile.
Another river, the Katonga, was once thought to flow from Victoria. It was believed to head west to Lake George, named after Prince George, the future King George V. The river actually could flow from Victoria in the past. Geological shifts in the East African Rift altered this. Now the situation is a bit more tricky. The river’s waters can flow in both directions.
Lake Victoria Islands
There are over 3,000 islands on Lake Victoria. Some are tiny, but some are large and inhabited. The largest, Ukerewe, covers 530 km² (204 sq mi). It's near Tanzania's Speke Gulf and the city of Mwanza.
Ukerewe is thought to be the largest lake island in Africa. Northwest on the Ugandan shore is the Ssese Islands group. It is the lake's largest archipelago with 84 islands. Kenya’s Rusinga Island is notable. Here, the skull of a hominid ancestor was found by Mary Leakey.
She later made significant discoveries in Tanzania’s Olduvai Gorge. Today, archaeological work continues on the island. A discovered fossil forest reveals ancient apes and the first hominids that lived here millions of years ago. Other islands on Victoria also hold historical treasures. Kenya's Mfangano is home to ancient rock art. Important primate fossils were found on Kenya's Maboko Island.
Since the 1930s, hundreds of fossilized apes and other animals, including reptiles and mammals, have been discovered. Palaeotragus, ancient short-necked giraffes, and Trionyx, soft-shelled turtles, are examples. Today, Uganda's Ngamba Island hosts a large chimpanzee sanctuary.

Ngamba Island Chimpanzee Sanctuary shelters about 50 orphaned chimpanzees rescued from poachers, circuses, and other exploitative places across East Africa.
Island National Parks
Three islands on Lake Victoria are entirely designated as national parks. In Kenya there is Ndere Island with Ndere Island National Park. Ndere, covered in grasses, is a bird sanctuary. It is home to hippos, crocodiles, impalas, monitor lizards, snakes, baboons, and other wildlife.
Two other ones are on the Tanzanian territory. Saanane forms a national park with two other islets. All of them lie within the borders of Mwanza City, Tanzania. You can walk through the park, observing antelopes and zebras grazing nearby. They are accustomed to visitors. Because some animals are in enclosures, unprepared guests might see Saanane as a zoo-like park. We advise against visiting Saanane. It's better to take a safari tour to true wildlife national parks.
The rather large Rubondo Island sits in the southwest corner of Lake Victoria. It's surrounded by smaller islets. Together they form Rubondo Island National Park. The main island is covered in lush forests. Its sandy shores are washed by calm waters. Geologically, Rubondo consists of flooded volcanic hills. Chimpanzees call the forests of this island home. Elephants, antelopes, and other animals roam the valleys. Rubondo Island Park is exceptionally interesting with its unique ambiance.
It reminds one of fantasy movies where wild nature reigns. A visit here, spending days away from familiar civilization, is worthwhile. We can also mention a few other conservation areas within the Lake Victoria basin. One of them is Kenya's Ruma National Park, located 10 km (6 mi) east of Victoria. It's known as the last sanctuary for the roan antelope in Kenya. The park is also home to leopards, rhinos, buffaloes, olive baboons, bushpigs, kongoni and topi antelopes, venomous vipers, cobras, and many other animals.
Can You Swim in Lake Victoria?
Given the lake's vastness, swimming safety varies. Some spots are frequented by locals, while others are truly dangerous.
Poor Water Quality
Parts of the lake suffer from pollution due to in-flowing rivers and streams.
Parasites Causing Schistosomiasis
In certain locales, water is infested with blood flukes from the class of flatworms.
Wild Animals
Significant pollution plagues Lake Victoria. It stems from untreated wastewater, including industrial and domestic effluents. Chemicals and fertilizers from fields enter the lake through rivers. Many wash cars by the lake, spilling traces of oil and fuel. The high population density around the lake suggests a heavy pollution load. The inadequate sewage systems of large coastal cities also contribute.
These conditions facilitate the spread of diseases. For example, dysentery, malaria, and cholera. High population density, inadequate sanitation, and weak governance increase health vulnerabilities. A particular disease that we mentioned above stands out. It is schistosomiasis, also named bilharzia after Theodor Bilharz. He discovered the parasites that spread it. These small trematodes, parasitizing snails, seek to infect mammals, including humans.
They penetrate the skin in water, heading to the stomach or bladder to reproduce. Skin reaction includes itching and rash. Internal effects later include pain and blood in excretions. Historically lethal, schistosomiasis is now treatable with affordable antiparasitic drugs. Originating from the African Great Lakes, it ranks behind malaria in tropical disease impact. It affects fishermen and fieldworkers who frequently contact with lake waters.
Crocodiles on the lake’s coast and islands pose a notable danger to local bathers and adventurous tourists. Numerous media reports detail crocodile attacks and fatalities. Searches for "crocodile Lake Victoria" yield many recent accounts. Those reptiles are really common in the lake.

Why is the Lake Called Victoria?
The lake got the name Victoria from British explorer John Hanning Speke in 1858. He found it and declared it the Nile's source, which was sought by many explorers at the time. At that time, the United Kingdom was in an era of achievement across various sectors: industrial, cultural, scientific, and political. This era would later be named the Victorian era.
A long period of peace fueled the industrial revolution and economic boom. This allowed Britain to venture into distant lands for conquest and exploration. It vied with the Russian Empire in Asia and neared colonial expansion in Africa. This period was marked by bold and numerous expeditions, including that of Speke and Burton.
For over a century and a half, the lake has been called Victoria worldwide. But did it have another name by which local inhabitants called it? Yes, it had several, because various peoples with different languages lived along the shores of the large lake, which resembled a sea. Let's mention the most common local name for Lake Victoria - Nyanza, which means "lake" in Kinyarwanda.
In Luganda, it was called Nalubaale, meaning "Home of the Spirit." In Swahili, it was Ukerewe, named after the local Kerewe people. Now, this name remains with the largest island. There are other names for the lake in the three countries of the East African community that share it. In the 1960s, there was an attempt to choose a new common name, but the idea failed. The lake continues to be known by different names depending on the region.

How was Lake Victoria Discovered?
Of course, indigenous Africans of the Lake Victoria region always knew of the lake. Many people lived nearby or traveled here. However, no maps or records of the great lake survived since those older times. The African peoples did not have a writing system. The world learned of the existence of the vast African lake twice. First from Arab explorers, and then from Europeans.
Arab Geographers
Arab traders were the first to mention Lake Victoria. They scoured the inland routes of the continent for gold, ivory, and valuable natural resources. By the 12th century, the first map showing a vast part of Africa emerged. It not only displayed Lake Victoria but also noted it as the Nile's source.
This was centuries before Europeans "discovered" it in the 19th century and then debated its status as the Nile's source. The map's creator was the geographer Muhammad al-Idrisi, who worked at Sicilian King Roger II's court. Roger II was considered highly enlightened, inviting scholars and philosophers to his kingdom. He conceived the idea of compiling all known geographic knowledge. Al-Idrisi led the commission formed for this task.
Their 18-year effort yielded two remarkable works: a silver planisphere-a disc with a detailed world map-and a book of maps. Unfortunately, the silver planisphere didn't survive. But the book, known as Tabula Rogeriana or the Book of Roger, still exists. Published in 1154, it contains 70 maps with the most accurate geographic details known before Columbus's era.
Its full Arabic title translates to "The Delight of Him Who Desires to Journey Through the Climates". This detailed work cites several thousand geographical locations. The main map became a large image of the then-known world, depicted as an inverted geographical map with the south at the top.
Of particular interest is the large colorful map taken from a 1456 copy that you see above. We should also look at some maps from the original publication. Let's flip to the more familiar orientation with the north at the top. As you can see, the map fairly accurately shows the Nile flowing towards the Great African Lakes.
