All about Lakes
A lake is a large body of water surrounded by land. Lakes form in hollows in the ground that fill with water from rain, rivers or melting ice. Most lakes contain fresh water, although some, like the Great Salt Lake in the USA, are salty.
Lake Baikal in Russia is the deepest lake in the world and holds about a fifth of the world's unfrozen fresh water. Lakes support fish, birds and plants, and they are important sources of drinking water for many people.
