One portion of its territory records the greatest rainfall of any spot on earth; another, of several hundred thousand square miles, is seldom watered with a drop of rain and is entirely dependent for moisture upon the melting snows of the mountains.

It aids agriculture by preventing floods and storing the surplus rainfall in the soil for the use of farm crops.

The National Forests aid greatly in conserving and making available for use the precious limited rainfall of the arid regions.
