I just ran across this image of a dessicated earth, with all the water in the world (oceans, ice caps, groundwater, lakes, clouds — everything!) sucked up and collected into that little blue sphere. (The picture was made by the USGS — specifically Howard Perlman, Jack Cook, and Adam Nieman). That main bubble is 860 miles in diameter - and if it burst, it would flood the contiguous United States to a depth of 107 miles.
The medium sized sphere is all liquid fresh water. 99% of it is trapped in the ground where it’s hard to reach.
The tiny speck above Atlanta, Georgia is the fresh water in lakes and streams. That’s the water we all rely on.
