This table shows that most water in the planetary system is stored in the world's oceans and polar ice. The atmosphere only holds a small fraction if the earth's water, mostly in the form of water vapor and cloud.
Note that rivers and streams contain less water than the atmosphere. This makes sense when you consider that rivers and streams are fed exclusively by water vapor in the atmosphere, so that the atmosphere actually represents an ultimate reservoir for rivers and streams.
