Uh oh, you hit on my topic...
Yes, America is running out of water. The reason is rather plain. We use more freshwater than nature replenishes, combined with several desert
cities that consume water like they are in the tropics. The West is in peril, not the east. Back East, the climate delivers enough rainfall
throughout the year that water shortages aren't the norm. Someone mentioned Atlanta, I'll have to do some research on that.
To begin, this is absolutely the best and truest motto regarding Western US water resources:
Use it or Lose it!
The Olgalalla Aquifer ( Link )
About 27 percent of the irrigated land in the United States overlies this aquifer system, which yields about 30 percent of the nation's ground
water used for irrigation. In addition, the aquifer system provides drinking water to 82 percent of the people who live within the aquifer
boundary.[2]
We are pulling water out of this aquifer at a rate that is slightly faster than the flow of the Colorado river, to the tune of ~26 cu km/year. That's
26 1 kilometer cubes, if you didn't get it the first time, equates to about 2.7 feet/year lost. It replenishes at ~1-4 inches/year. Hydrologists
don't know exactly how much water is down there, but have been warning for years that we
will suck it dry with our current practices. When
that happens, expect the "breadbasket" to become the new (old) desert grassland.
Colorado River
Speaking of the Colorado, did you know that the US retains 95% of the water that flows, leaving a measly 5% to follow the border along Mexico? (Where
it actually dries up before reaching the sea.) And did you know that we divert ~75% of the water at the border, sending it to California's Salton Sea?
Sadly by the time the water has run the course on the US side it is so completely salinated and carries so many agricultural chemicals that it ruins
the farmlands in Mexico. And the Salton Sea? It used to be a migratory bird stop, like Mono Lake once was. Now it's dead, and toxic.
Mexico had to sue us over the salinity of the water. They won, and the US built a 250+ million dollar desalinization plant in Yuma, that (due to
water politics) has only been operational a few months since it's completion in 1992.
Who is ruining the Colorado you ask? Big Ag is. They grow massive amounts of low-value crops, and as a side note get unheard of deals on their water.
Like HUGE deals. LA pays ~$600 for an acre-foot of water (that's an acre, covered by 1 ft. of water.) Corporate Ag producers are getting it for
~$15! Thank Washington for that, they have had an aggressive welfare program for agriculture since the turn of the last century.
Oh wait, I forgot to mention: They are growing these crops in the DESERT. Utah, Arizona, Nevada, Southern California, New Mexico...Seems like a
logical place to grow vast commercial crops.
Snake River
Starting at the feet of the Tetons in Wyoming, the Snake River "snakes it's way south, into Idaho, across then up the panhandle, dropping into
Washington, finally dumping into the Columbia River and to the sea. I want to highlight the Snake because it is very very typical of Western waterway
battles happening almost everywhere.
There are 15 dams on the snake river (~28 on the entire Columbia River watershed) built in order to supply farmers and towns with water. Funny thing
though, the Snake river used to be prime (i mean PRIME) Salmon spawning grounds. There is a very long and bitter war being fought every day, between
the fishing industry and the agricultural industry over Snake River dams. Add to that a population explosion in Idaho in the last 20 years: just
under 20% increase from 2000-2009, and you can see that the water is getting pretty thin up here.
Another threat to the Snake River's water is all those desert cities, hungry for water. Way back in 1986 Los Angeles tried to make a move on the
Snake's water, and the threat is still looming. Subsequently LA is all for the Fishing industry's goal of taking out the dams. If ag is destroyed
along the Snake, then LA can get at the water that much easier.
So if you made it through all that, you can see that the issues are deeply complex, affect nearly everyone living in the Western half of the US, and
con really only be resolved through major cultural shifts. How do we fix it you ask? I thought you would never ask!
First of all, desert cities need to realize that they are desert cities. Look at this:
LA:

Las Vegas:

Pheonix:
pics4.city-data.com...
To put all that water in perspective: The Bellagio Resort in Las Vegas (from the pic) ALONE loses to evaporation ~12 million gallons a year from their
"lake". Multiply that by all the lawns and swimming pools and fountains and you can see that these cities are not in any way trying to live within
their water-means.
Second, the farmers/corporations existing in desert climates need to consider growing logical crops. For example the Snake River plain is where most
of your big fat yummy potatoes come from. The Snake River plain is high desert! Potatoes take a metric sh*t-ton of water to grow! 95% of the snake
river water is used for agriculture!
Third, we as Americans need to get off our addiction to meat. Yes meat. How much water is consumed to make a pound of beef? Actually hard to get a
straight answer, cause there's Beef industry studies (~600gal) and Vegetarian studies (~2500gal), but as you can see...that hamburger you just ate
dipped into the water supplies. Newsweek once wrote about it, saying while the numbers aren't clear, the water used to raise a 1000 pound steer would
float a battleship!
Fourth, we as a civilization need to evaluate our water useage. It makes no sense whatsoever to have green, water-wasting lawns in dry arid climates.
All that junk about turning off the tap when you brush your teeth, taking quick showers, "if it's yellow let it mellow..." That stuff is all TRUE!
We NEED on every level to conserve water and use it judiciously. If we don't the lesson we or our kids will learn will be a very harsh and expensive
one.
PS: Did you know that this was/is a real idea under consideration?

Imagine the size and cost of a project like this. It was conceived in 1950...How much more serious is the situation 60 years later?
Post PS: Grab a copy of
Cadillac Desert , it's a great
book outlining in depth what is happening with water. Latest revision was in 1993, and
nothing has improved since then.
OK one last thing:
