Summary
[motion picture] Defines lakes in terms of their physical features, how they are created and destroyed, and their uses.  Indicates that the size and shape of a lake may vary, but that all lakes are formed because there is a depression in the land.  Describes natural and man-made lakes and their uses as sources of food, recreation, and electricity.  Shows that lakes must be protected from pollution if they are to continue to be useful to man.
