[:ja]大西宇宙飛行士が撮影した、ケニア🇰🇪、ウガンダ🇺🇬、タンザニア🇹🇿に囲まれたアフリカ最大（68,800km2）のビクトリア湖です。面積は広いものの、湖全体の平均水深は40mに過ぎません。
CNNの記事によると、実はビクトリア湖は毎年5000人が死亡する「世界一危険な湖」と言われています。赤道直下のビクトリア湖は水温が高く、天気が変わりやすく嵐が発生しやすい天候に加え、通信インフラの未発達などにより、漁師側の側でも事前に天気予報を確認できないこともあるようです。
また、1950年代に全長2mを超す肉食の外来魚であるナイルパーチ（スズキ）が食用として放流され定着し、湖の固有種であった草食性の魚が激減し、湖の生態系は壊滅的な状態になりました。その結果、地元の漁業も経済も大きな影響を受けました。

[Earthview Wonders] No.180: Lake Victoria
Astronaut Takuya Onishi captured Lake Victoria, the largest African lake (68,800km2) divided among Kenya🇰🇪, Uganda🇺🇬 and Tanzania🇹🇿. The lake occupies a shallow depression with an average depth of 40m.
According to CNN’s article, Lake Victoria is said to be the “world’s most dangerous lake” with annual 5,000 deaths. Lying on the Equator, Lake Victoria has higher temperature with erratic weather conditions, and poor communications hinder fishermen from expecting bad weather.
Further, the introduction of Nile perch in 1950s, the carnivorous exotic fish, swept indigenous hervivorous species in the lake, and resulted in the imminent destruction of the ecosystem. As a result, local economy based on the fishery had davastating outcome.
The scenery of the lake on the ground is as follows.
