The American Southwest: Twice the people, half the water? by Kathleene Parker

The water situation grows increasingly dire in the southwest. From Kathleene Parker at progressivesforimmigrationreform.org:

Showing reservoirs, including iconic Lake Mead at Hoover Dam, shrunk to a fraction of their intended size, national news media is reporting that the American Southwest is in the worst 20-year drought in 1,200 years.

Yet, no one asked why President Biden is hellbent on increasing immigration – which has exploded the U.S. population by an average approaching 30 million a decade over the last three decades – when he can’t ensure adequate water for those here now. The Southwest is the fastest growing region of ours, the third most populated nation and one of the world’s fastest growing developed nations – something else never reported.

There are roughly 200 reservoirs along the length of the Colorado River – the primary water source for at least 45 million people in the Colorado River Basin and beyond – that were thought to ensure a 50-year water supply in drought. Yet, by the early 2000s, that 50-year supply was sucked dry!

At Lake Mead, the water level recently fell below the trigger point for the first-ever federal water emergency. That will mean mandatory water cutoffs, delivering a body blow to the Southwest’s economy and drying up farmland needed to feed the nation’s exploding population. But even that might not stop a collapse of the Colorado River system, a vast network of diversion projects and reservoirs stretching from Wyoming to the Mexican border. Meaning, reservoirs might run dry and diversions might no longer take water into cities of millions!

Today’s Phoenix, Arizona, was so named when settlers in the 19th century realized that they were building on the ruins of some long-ago civilization – that of the Hohokam – and named their new settlement after the mythical bird that arises from the ashes of another.

The Four Corner states – Colorado, Arizona, New Mexico and Utah – today are dotted with the ruins of the mysterious cliff dwellings and towns of the ancestral Puebloans – the Hohokam, the Anasazi and the Mimbres – who were forced into what we call the Great Abandonment, during the prolonged drought of the late 1200s though the mid-1300s. Hundreds of thousands of people fled what had been relative paradises in Colorado’s Montezuma Valley and on the once-verdant Mesa Verde, in the Gila Mountains of New Mexico and on the high uplands of Arizona, relocating to areas, mostly along the Rio Grande, with somewhat dependable water.

Leaking Las Vegas: West’s Biggest Reservoir Nears Critical Threshold, by Tyler Durden

Too many people are trying to take too much water from the Colorado River. From Tyler Durden at zerohedge.com:

Lake Mead – the West’s largest reservoir – is running dry again and is on track to fall below a critical threshold in 2020, according to a new forecast by the Bureau of Reclamation.

In 2016, Lake Mead water levels drop to new record lows (since it was filled in the 1930s) leaving Las Vegas facing existential threats unless something is done. Las Vegas and its 2 million residents and 40 million tourists a year get almost all their drinking water from the Lake and at levels below 1075ft, the Interior Department will be forced to declare a “shortage,” which will lead to significant cutbacks for Arizona and Nevada.

And now, two years later, the situation appears to be getting worse as The Wall Street Journal reports, in a prediction released Wednesday, the Bureau of Reclamation, a multistate agency that manages water and power in the West, said there is a 52% probability that water levels will fall below a threshold of 1,075 feet elevation by 2020.

“The very big concern is the perception that water supplies are uncertain,” said Todd Reeve, chief executive officer of Business for Water Stewardship, a nonprofit group in Portland, Ore., that works with businesses on water use nationally.

“So if a water shortage is declared, that would be a huge shot across the bow that, wow, water supplies could be uncertain.”

The Colorado River, which supplies water to 40 million people from Denver to Los Angeles, has been in long-term decline amid what bureau officials call the driest 19-year period in recorded history.

Lake Mead, which serves as the biggest reservoir of the river’s water, resumed its decline this year after the region returned to drought conditions. As of Wednesday, it stood at 1,078 feet, about 150 feet below its peak.

If Lake Mead’s water levels fall below the 1,075 feet threshold, it could trigger the first ever federal shortage declaration on the Colorado River – which experts say could undermine the Southwest’s economy.

Outlook for vital Southwestern US river remains grim, by Dan Elliott

The major artery of the Southwest US, the Colorado River, is in bad shape. From Dan Elliott at yahoo.com:

DENVER (AP) — The outlook for the most important river in the Southwestern U.S. remains grim this summer after April storms failed to produce much snow in the mountains that feed the waterway, forecasters said Monday.

The National Oceanic and Atmospheric Administration said the Colorado River is expected to carry only 43 percent of the average amount of water into Lake Powell, one of two huge reservoirs that store and distribute the river.

It’s the fifth-lowest forecast in 54 years.

“It’s pretty dramatic. It’s a very low runoff season,” said Greg Smith, a hydrologist with the agency.

But officials have said that Lake Powell and its companion, Lake Mead, will be high enough to avoid mandatory cutbacks for water users this year.

The Colorado River serves about 40 million people and 6,300 square miles (16,300 square kilometers) of farmland in United States and Mexico.

Arizona, California, Colorado, Nevada, New Mexico, Wyoming and Utah all use the river or its tributaries, along with 20 native American reservations.

The river is under increasing stress because of rising demand and declining flows. The region has been in a drought for 18 years — long enough that some researchers say it may represent a permanent shift.

Global warming is also contributing to the reduced river flows, scientists said.

Last year’s snowfall was uneven but mostly below average across the mountains that feed the Colorado.
