Water shortages, and what they mean (Page 1/2)

One example: The Colorado River level slowly getting lower.
Sounds like this could affect food sources too because of lack of irrigation.
Also they mention threats to major power generators on Lake Mead and Lake Powell.
They inserted folks blaming "climate change" in the video. Well yes a changing climate causes lots of things, it has throughout all of time. Changing climates have flooded civilizations, dried out civilizations and covered them in sand. Long term changes. Regardless of its cause (which people like to argue about), it would be wise to somehow prepare for less water, less food and less power.

Nearly half the water that comes out of my tap is from the Colorado river. An equally large portion is from the Salt and Verde rivers. One of the nation's largest metropolitan areas is skating on thin ice, yet within a few miles from my house there are ducks, osprey, eagles, herons, egrets and even pelicans.

Look up the Sinagua people.

Eventually the ignorant politicians will finally realize that desalination is the best way to go. Even as a temporary basis until we have that much needed rainfall to refill the supply. Energy Recovery Inc. here in the Bay Area was one of the innovators of desalination. They had multiple plants all over the world providing clean water to millions of people. I don't understand the ignorance here in the U.S. You have a U.S based company that no one wants to use so they do all of their work overseas.

YES it is more expensive but it works.

Reminds me of a lot of things made and designed here.

All of the coastal cities should be preparing by building desalination plants....But also, I was looking at the idea of the Mississippi basin flooding while the western states are in drought (Or vice-versa); Why not build an Aqueduct between the two regions and a large reservoir in between to store needed water?

Then again, I have been told that Man could never pull this kind of engineering off......Too expensive and complicated.....It would be like the Romans building aqueducts back 2000 years ago.....That would be crazy....right?

The Hohokam people lived in the Mesa area for nearly 1,500 years. Hohokam, (a Pima Indian word meaning ‘‘those who have disappeared’’), first appeared around 1 CE initially growing beans, squash, corn and cotton serving a very small population of less than one thousand. Around 600 CE, the Hohokam population grew too large for sustainable living. As the population grew further from the river, the Hohokam began to construct canals for irrigation. Using digging sticks, the Native Americans excavated 12-feet deep canals, fanning into a larger network of smaller canals.


The canals that we use here today are based on the ancient Hohokam system.

These two projects are the reason Phoenix is possible:

I took these pictures from a friend's airplane over 30 years ago:

Stewart Mountain Dam - Saguaro Lake



Roosevelt Dam - Roosevelt Lake

williegoat,
Looks like those dang'd birds are drink'n up all your water.

Those birds are at the "Glendale Recharge Ponds" at the end of the canal. Their purpose is to recharge the groundwater and are only about five feet deep. They are about a mile west of the stadium.

I like the idea of the desalinization plants, but wouldn't the outflow of very salty water cause problems in the area?

I suspect that the currents would carry the extra salty water elsewhere, and that it would potentially mix. But I remember reading somewhere about issues with the water being saltier, and creating a layer of extra salinized water that is a "dead zone" for life and doesn't mix as you would expect because of the specific gravity differences or something.

I don't know for sure, The Science™ is really hard to follow anymore since it's became so "settled".

I know nothing about desalinization, but would it be worthwhile to make salt from the waste?

It might just be a Dandi idea.


(In the spring of 1930, Gandhi led a march to the village of Dandi on India's west coast to make salt from seawater, in an act of defiance against British imperialism.)
