It also plays a fundamental role in hydroelectrical power generation and is home to many interesting animal species. For example, native cichlids are going extinct now. Lake Victoria's Falling Waters. [101] Increased logging and act of deforestation has led to environmental degradation around the region reducing the absorption of polluting chemicals and deteriorating the water quality.[102]. This incredible water volume makes it perfect for being the source of the Nile. These cities and towns are also home to many factories that discharge some chemicals directly into the lake or its influent rivers. Although this region is resource-rich, huntable animals are limited. Learn how and when to remove this template message, "The Victoria Nyanza.

Due to human lifestyles, the lake has become contaminated and polluted with chemicals and plastics. At nearly 400,000 years old, the lake is considered a young body of water in a geological sense. [39][44] The Victoria haplochromines are part of an older group of more than 700 closely related species, also including those of several smaller lakes in the region, notably Kyoga, EdwardGeorge, Albert, and Kivu. Of the numerous islands in the lake, Ukerewe, north of Speke Gulf, is the largest, with wooded hills rising 650 feet (200 metres) above the lake.

For most lakes, the rain that falls over a broad region flows into the lake through rivers, streams, and ground water. The only outflow from Lake Victoria is the Nile River, which exits the lake near Jinja, Uganda.

In contrast, the Owen Falls (now flooded by a dam) between Victoria and Kyoga were essentially a series of rapids that did not effectively block fish movements between the two lakes. It has an area of 26,828 square miles where over 200 species of fish live. The fishing of Nile perch is the backbone of local economies.

[64] There is little doubt that Haplochromis played an important role in returning detritus and plankton back into solution. [41], Other factors which may have contributed to the decline of the water hyacinth in Lake Victoria include varying weather patterns, such as El Nio during the last few months of 1997 and first six months of 1998 bringing with it higher levels of water in the lake and thus dislodging the plants. Lake Victoria is one of the African Great Lakes. Updates? Serengeti National Park is situated around northern Tanzania. Nevertheless, the natives continued to dominate fisheries until the 1970s where their decline meant that there was a strong shift towards the non-native Nile tilapia (now 7 percent of catches), non-native Nile perch (60 percent) and the native Lake Victoria sardine (30 percent). John Speke first saw the lake he was to call Victoria on 3 August 1858, from a point where the town of Mwanza now stands. Other native species include the clawless otter and sitatunga. The principal predatory fishes are Lates niloticus, Bagrus docmac, Clarias mossambicus, Schilbe mystus and some species of Haplochromis (sensu lato).
