Read the passage and answer the question.

Lake Baikal is a huge lake in Siberia, Russia. It is the biggest fresh water reservoir in the world. The lake is near Irkutsk. Somewhat crescent shaped, it is in the southern Siberia area of Russia. The lake is completely surrounded by mountains.
Baikal is about 636 kilometres long. It is 20 to 80 kilometres wide. At its deepest point, it is 1,700 metres deep. With this depth, it is the deepest lake on Earth. The lake is a UNESCO World Heritage Site. It holds about 20% of the world's unfrozen surface fresh water. The word baikal means "rich lake", explaining the rich plants and animals found in the lake. There are more than 2,600 species of plants and animals. Of the 50 species of fishes, the most numerous are bullheads. Also abundant are the omul, salmon and lake whitefish.
Baikal's age is 25-30 million years: it is one of the oldest lakes. More than 300 streams and rivers feed into Lake Baikal like Reka and Vitim rivers, but the Angara River is the only outlet. The Selenga River is the largest source of water coming into Lake Baikal. Flowing north from Mongolia, it contributes nearly 50 percent of the lake's water. Lake Baikal may be warmer than other parts of Siberia, but in the winter it still gets very cold. The average air temperature in winter is minus 21 degrees celsius. Despite its size, Lake Baikal freezes over in the winter and usually melts in May or June.
