Water is our most precious resource and we all need to conserve and preserve it before we are a dry world that is a wasteland. I plead for everyone to take seriously this issue before it is too late.

Lake Mono Needs Help
1941, the Los Angeles
Department of Water and Power began diverting Mono Lake's tributary
streams 350 miles south to meet the growing water demands of Los Angeles. Deprived of its freshwater sources, the volume of Mono Lake halved, while its salinity doubled. Unable to adapt to these changing conditions within such a short period of time, the ecosystem began to collapse. The photo at left was taken in 1962, after the lake had already dropped almost 25 vertical feet.
When the Los Angeles Department of
Water and Power began diverting Mono Lake's tributary streams in 1941, the Lake
No longer received its total annual freshwater inflow. By 1982, Mono Lake
dropped 45 vertical feet, lost half its volume, and doubled in salinity. Vast
alkali dust flats were exposed, the islands where birds nest became connected
to the mainland, and the brine shrimp and alkali flies on which millions of
migratory birds depend were threatened.
Mono Lake makes for great photos, but soon it will become salt flats if we don't save it.

# 1 Most Endangered River in U.S. "Colorado"
The Colorado is a winding resource of beauty and age.
All reservoirs along the Colorado River might dry up by mid-century as the West warms, a new study finds. The probability of such a severe shortage by then runs as high as one-in-two, unless current water-management practices change, the researchers report. Even under the harshest drying caused by climate change, the large storage capacity of reservoirs on the Colorado might help sustain water supply for a few decades.The Colorado River system is enduring its 10th year of a drought. Fortunately, the river system entered the drought in 2000, with the reservoirs at approximately 95 percent of capacity. The reservoir system is currently at 59 percent of capacity. Roughly 30 million people depend on the Colorado River for drinking and irrigation water. To the right is one of the depleting areas. Between 2026 and 2057, the risks of fully depleting reservoir storage will increase seven-fold under the current management practices when compared with risks expected from population pressures alone. Implementing more aggressive management practices - in which downstream releases are reduced during periods of reservoir shortages - could lead to only a two-fold increase in risk of depleting all reservoir storage during this period, according to the study.
This is an actual picture from part of the Colorado River
Is this the future of its entire environment?

This Video is Shocking Evidence
Lake Mead is the largest reservoir in the United States.. It is 24 miles from Las Vegas Nevada and extends into Arizona It was created by Hoover Dam and supplies water to that desert region. Lake Mead is 112
miles long when the lake is full, has 550 miles of shoreline,
is around 500 feet at greatest depth, has 247 square miles of surface, and when filled to capacity, 28 million acre-feet of water. However,
the lake has not reached this capacity in more than decade, due to increasing
droughts.

The Worst Case of Water Depletion Has Already Happened
The Aral Sea was once the fourth largest sea in the world. A once-large saltwater lake straddling the boundary between Kazakhstan to the
north and Uzbekistan to the south was considered an oasis. Now It is barren and the ground is polluted with toxic chemical and the scant water that is left is thick with salt.
This region had 500 species of birds, 200 species of mammals, and 100 species of fish before the Soviet Union started diverting the water to irrigate crops, mostly cotton. Cotton was considered "White Gold" for the Soviets, but in just 40 years, starting in 1960, this white gold has destroyed the environment, animals, and the lives of human beings. It is at 1/4 of its original size today.
IS IT WORTH IT?

Look at the Danger of Our Own Water Suppy

Approximately 95 percent of the water pumped from the Ogallala is for irrigation. The High Plains area represents 65 percent of the total irrigated acreage in the United States. The quality of the water pumped from the aquifer is suitable for irrigating; but in some places, the water does not meet U.S. Environmental Protection Agency (USEPA) drinking water quality standards. For example, some constituents identified above EPA standards include sulfate, chloride, selenium, fluoride, nitrate, and total dissolved solids.
"The Ogallala is a designated ground water basin. It is designated by LAW to be non-tributary to surface streams and has been also determined to be non-rechargeable.
The Ogallala is mined knowing that it has a predetermined life of a hundred years. Withdrawals from the Ogallala are allowed based on the number of acres owned overlying the aquifer. A calculation is deliberately made using the total number of acres, volume in the Ogallala and dividing by 100 to get the amount allowed per acre above the Ogallala to be withdrawn/allowed each year.
When the Ogallala is gone, & its gone & and those who have depended upon it will be high and dry & hard to believe that those affected have not known this for years ( and they do) & their permitting process spells out the calculations and credits & for as long as the water lasts.
Maybe someday, California & Nevada in particular will come to realize the significance of a non-tributary Source of fresh water that can yield a million acre feet of water EACH YEAR which cannot be depleted ! They too will destroy their groundwater aquifers rather than seek a reliable permanent water Source which can be developed without damage to the environment or the water rights of others and can be delivered/distributed without outside power."
