re: Image showing all the water on Earth as spheres

Salt and fresh
There are three blue spheres.
ETA: Here we go:
All Earth's water, liquid fresh water, and water in lakes and rivers
Spheres showing:
(1) All water (sphere over western U.S., 860 miles in diameter)
(2) Fresh liquid water in the ground, lakes, swamps, and rivers (sphere over Kentucky, 169.5 miles in diameter), and
(3) Fresh-water lakes and rivers (sphere over Georgia, 34.9 miles in diameter).

Are you saying the water shown is strictly the water in the continental United States?

Since they drained it if you zoom in you can see a submarine in the gulf of mexico

Given the first two words I quoted from the page I linked to was, "All Earth's," no.

This drawing shows blue spheres representing relative amounts of Earth's water in comparison to the size of the Earth. Are you surprised that these water spheres look so small? They are only small in relation to the size of the Earth. This image attempts to show three dimensions, so each sphere represents "volume." The volume of the largest sphere, representing all water on, in, and above the Earth, would be about 332,500,000 cubic miles (mi3) (1,386,000,000 cubic kilometers (km3)), and be about 860 miles (about 1,385 kilometers) in diameter.
The smaller sphere over Kentucky represents Earth's liquid fresh water in groundwater, swamp water, rivers, and lakes. The volume of this sphere would be about 2,551,000 mi3 (10,633,450 km3) and form a sphere about 169.5 miles (272.8 kilometers) in diameter. Yes, all of this water is fresh water, which we all need every day, but much of it is deep in the ground, unavailable to humans.
Do you notice the "tiny" bubble over Atlanta, Georgia? That one represents fresh water in all the lakes and rivers on the planet. Most of the water people and life on earth need every day comes from these surface-water sources. The volume of this sphere is about 22,339 mi3 (93,113 km3). The diameter of this sphere is about 34.9 miles (56.2 kilometers). Yes, Lake Michigan looks way bigger than this sphere, but you have to try to imagine a bubble almost 35 miles high—whereas the average depth of Lake Michigan is less than 300 feet (91 meters).
A little context for the picture.

North Texas was in drought conditions for a number of years and water restrictions aplenty. We have three sources for water. Their combined capacities we down to 28%, which is scary low and no more than a two year supply. Received abundant rainfall over a five month period in which all three reservoirs reached capacity and that remains...Is pretty amazing to experience.
Never thought much about water growing up in South Louisiana, I do now, and am amazed how much water and access to water there is.
Have always thought the Texas legislature needs to fund a water purification plant on the Gulf

Didn't need that to figure it out, but thanks.

Not to be nerdy but do the water spheres represent the accumulation of water that is condensed in clouds above the earth's surface and does it account for the water that flows below the Earth's surface? And, how about all of the households that have multiple commodes already full of fresh water?
Heh heh.
(I'm really not a fan of this type of modeling because it's pointless except to the one making the model.)
Eta: Sorry. Juat had a movement. Want to also ask if this model includes all accumulated fluid in the mortal bodies of living beings since they also have @75% moisture content. And what about cacti? Is that included? Water chestnuts?
Heh heh.

Well it shows that what most people believe/think is inaccurate. Most people look at a globe and would say 3/4 of the world is covered in water....plenty to drink, water lawns, etc. However, this shows that in actuality, fresh(usable) water is not so abundant and easy to come by.
Lots of the major cities pull water out of the ground and then drain it into rivers where a lot of it will never return to the ground it was originally in. This basically creates a coning effect in ground water under cities which leads to water shortages. It's a situation that has been neglected for so long that will become more critical to resolve in future years.

The big one does, yes.

Not sure about this.

I am curious to read where you might think this water disappears to since we live in an enclosed environment? Does it shift to outer space?

I didn't say it disappears. Do you think if you put a well in the ground, that you will have infinite water down there? The aquifer has to recharge. If water is drawn out faster than it can recharge through drainage, then a water cone will form around the draw point.
cone of depression*

No not in that spot. You might have to move over to the right a little bit and drill a new well. It's just like any other Earthly resource, that should you have no plan for replenishment you might have to change your environment. The water doesn't disappear from the earth; it just shifts. Change is the constant and that truly is the problem with man. No one likes change.
