Where is the biggest lake in the world?

Biggest lake - the world's biggest lake is Lake Superior, between America and Canada. It covers an area of nearly 32,000 square miles. But Superior is not the lake with the most water. Lake Baikal in southern Siberia has far more water, because although little over 12,000 square miles in area, it is nearly 6,000 feet deep. Lake Superior is nearly as big as Austria. It is nearly 400 miles long and receives the drainage of about 200 rivers. There is virtually no tide. But during autumn and winter storms, waves can reach extremely dangerous heights. These waves are gradually eroding the shore, so the lake is slowly getting even bigger. Owing to the lake's great industrial advantages and transport facilities the water has become seriously polluted. Since 1965, however, the United States  Government has made efforts to purify the great lake.
