Being one of the biggest hydroelectric facilities in the United
States and a National Landmark, Hoover Dam generates power to
serve more than 1.3 million people. The dam also provides flood
control, irrigation, and water storage along the Colorado River.
Located 30 miles southeast of Las Vegas, the dam captures water
from the Colorado River and fills Lake Mead. The federal
government completed construction of the dam in 1936. Because
Colorado River water is so sought after, there are legal limits
as to how much water each party can take from the Colorado River.
Senators from the two states that border Lake Mead are calling
for the National Park Service to use some of the $1.5 billion
in natural disaster recovery funding the agency received to
address the drought-stricken reservoir. The latest federal
spending bill signed by President Joe Biden in December
allocated $1.5 billion to pay for recovery efforts at national
park lands that have been hit by natural disaster, including
severe flooding at Yellowstone National Park last summer that
washed out several sections of roads. In a letter sent Tuesday
to National Park Service Director Charles Sams and Office of
Management and Budget Director Shalanda Young, [senators from
Nevada and Arizona] asked that Lake Mead’s shrinking shorelines
also receive some of that financial attention to address the
long-term toll that 23 years of drought have taken on the
nation’s largest reservoir.
The Hoover Dam is one of the most impactful engineering feats
in American history. Completed on March 1, 1936, the dam spent
nearly a century harnessing the mighty Colorado River and
transforming parts of the arid Southwest into fertile farmlands
and bustling city centers. Here’s a look at the dam’s history
and how it shaped the region. The history of Hoover
Dam began in 1921, when a young Secretary of Commerce,
Herbert Hoover, proposed the construction of a dam on the
Colorado River. At the time, the Colorado River, which ran
uninterrupted from the Rocky Mountains to the Gulf
of California, was considered dangerous and unreliable.
According to the National Park Service, the river would
often flood, particularly in late spring and early summer,
when snow melted from the Rocky Mountains would surge
into the river.
Once hailed as the “American Nile,” the Colorado River spans
1,450 miles and supplies nearly 40 million people across seven
states plus northern Mexico with drinking water, irrigation for
farmland and hydroelectric power. But after decades of drought
and overuse, major reservoirs along the river are drying
up. As the Colorado River levels drop to historic lows,
tensions are rising between the seven states that depend on its
flow — Arizona, California, Colorado, New Mexico, Nevada, Utah
and Wyoming. Their original agreement for distributing the
river water lacked foresight and failed to account for dire
circumstances like long-term drought. The American
Southwest now faces a crisis it knew was coming.
Momentum is building for a unique
interstate deal that aims to transform wastewater from Southern
California homes and business into relief for the stressed
Colorado River. The collaborative effort to add resiliency to a
river suffering from overuse, drought and climate change is being
shaped across state lines by some of the West’s largest water
agencies.
This tour explored the lower Colorado River firsthand where virtually every drop of the river is allocated, yet demand is growing from myriad sources — increasing population, declining habitat, drought and climate change.
The 1,450-mile river is a lifeline to some 40 million people in the Southwest across seven states, 30 tribal nations and Mexico. How the Lower Basin states – Arizona, California and Nevada – use and manage this water to meet agricultural, urban, environmental and industrial needs was the focus of this tour.

Las Vegas, known for its searing summertime heat and glitzy casino fountains, is projected to get even hotter in the coming years as climate change intensifies. As temperatures rise, possibly as much as 10 degrees by end of the century, according to some models, water demand for the desert community is expected to spike. That is not good news in a fast-growing region that depends largely on a limited supply of water from an already drought-stressed Colorado River.
Twenty years ago, the Colorado River
Basin’s hydrology began tumbling into a historically bad stretch.
The weather turned persistently dry. Water levels in the system’s
anchor reservoirs of Lake Powell and Lake Mead plummeted. A river
system relied upon by nearly 40 million people, farms and
ecosystems across the West was in trouble. And there was no guide
on how to respond.
The Colorado River Compact of 1922
divided the river into two basins: The Upper Basin (Colorado, New
Mexico, Utah and Wyoming) and the Lower Basin (Arizona,
California and Nevada), established the allotment for each basin
and provided a framework for management of the river for years to
come.
This event explored the lower Colorado River where virtually every drop of the river is allocated, yet demand is growing from myriad sources — increasing population, declining habitat, drought and climate change.

Innovative efforts to accelerate
restoration of headwater forests and to improve a river for the
benefit of both farmers and fish. Hard-earned lessons for water
agencies from a string of devastating California wildfires.
Efforts to drought-proof a chronically water-short region of
California. And a broad debate surrounding how best to address
persistent challenges facing the Colorado River.
These were among the issues Western Water explored in
2019, and are still worth taking a look at in case you missed
them.
The Colorado River is arguably one
of the hardest working rivers on the planet, supplying water to
40 million people and a large agricultural economy in the West.
But it’s under duress from two decades of drought and decisions
made about its management will have exceptional ramifications for
the future, especially as impacts from climate change are felt.
The Colorado River Basin’s 20 years
of drought and the dramatic decline in water levels at the
river’s key reservoirs have pressed water managers to adapt to
challenging conditions. But even more extreme — albeit rare —
droughts or floods that could overwhelm water managers may lie
ahead in the Basin as the effects of climate change take hold,
say a group of scientists. They argue that stakeholders who are
preparing to rewrite the operating rules of the river should plan
now for how to handle these so-called “black swan” events so
they’re not blindsided.
Summer is a good time to take a
break, relax and enjoy some of the great beaches, waterways and
watersheds around California and the West. We hope you’re getting
a chance to do plenty of that this July.
But in the weekly sprint through work, it’s easy to miss
some interesting nuggets you might want to read. So while we’re
taking a publishing break to work on other water articles planned
for later this year, we want to help you catch up on
Western Water stories from the first half of this year
that you might have missed.
Even as stakeholders in the Colorado River Basin celebrate the recent completion of an unprecedented drought plan intended to stave off a crashing Lake Mead, there is little time to rest. An even larger hurdle lies ahead as they prepare to hammer out the next set of rules that could vastly reshape the river’s future.
Set to expire in 2026, the current guidelines for water deliveries and shortage sharing, launched in 2007 amid a multiyear drought, were designed to prevent disputes that could provoke conflict.

As stakeholders labor to nail down
effective and durable drought contingency plans for the Colorado
River Basin, they face a stark reality: Scientific research is
increasingly pointing to even drier, more challenging times
ahead.
The latest sobering assessment landed the day after Thanksgiving,
when U.S. Global Change Research Program’s Fourth National Climate
Assessment concluded that Earth’s climate is changing rapidly
compared to the pace of natural variations that have occurred
throughout its history, with greenhouse gas emissions largely the
cause.
The Colorado River Basin is more
than likely headed to unprecedented shortage in 2020 that could
force supply cuts to some states, but work is “furiously”
underway to reduce the risk and avert a crisis, Bureau of
Reclamation Commissioner Brenda Burman told an audience of
California water industry people.
During a keynote address at the Water Education Foundation’s
Sept. 20 Water Summit in Sacramento, Burman said there is
opportunity for Colorado River Basin states to control their
destiny, but acknowledged that in water, there are no guarantees
that agreement can be reached.
Nowhere is the domino effect in
Western water policy played out more than on the Colorado River,
and specifically when it involves the Lower Basin states of
California, Nevada and Arizona. We are seeing that play out now
as the three states strive to forge a Drought Contingency Plan.
Yet that plan can’t be finalized until Arizona finds a unifying
voice between its major water players, an effort you can read
more about in the latest in-depth article of Western Water.
Even then, there are some issues to resolve just within
California.
It’s high-stakes time in Arizona. The state that depends on the
Colorado River to help supply its cities and farms — and is
first in line to absorb a shortage — is seeking a unified plan
for water supply management to join its Lower Basin neighbors,
California and Nevada, in a coordinated plan to preserve water
levels in Lake Mead before
they run too low.
If the lake’s elevation falls below 1,075 feet above sea level,
the secretary of the Interior would declare a shortage and
Arizona’s deliveries of Colorado River water would be reduced by
320,000 acre-feet. Arizona says that’s enough to serve about 1
million households in one year.

A drought has lingered in the
Colorado River Basin since 2000, causing reservoir storage to
decline from nearly full to about half of capacity. So far this
year, a meager snowpack in the Rocky Mountains hasn’t helped
much.
In fact, forecasters say this winter will likely go down as the
sixth-driest on record for the river system that supplies water
to seven states, including California, and Mexico.
On our Lower
Colorado River Tour, April 11-13, you will meet with water
managers from the three Lower Basin states: Nevada, Arizona and
California. The three states are working to finalize a Drought
Contingency Plan to take voluntary cuts to keep Lake Mead, the
nation’s largest reservoir, from hitting critical levels and
causing a shortage declaration.
Tickets are now on sale for the Water Education Foundation’s April 11-13 tour of the Lower Colorado River.
Don’t miss this opportunity to visit key sites along one of the nation’s most famous rivers, including a private tour of Hoover Dam, Central Arizona Project’s Mark Wilmer pumping plant and the Havasu National Wildlife Refuge. The tour also visits the Salton Sea, Slab City, the All-American Canal and farming regions in the Imperial and Coachella valleys.
Rising temperatures from climate change are having a noticeable
effect on how much water is flowing down the Colorado River. Read

Since 2000, the Colorado River Basin has experienced an historic,
extended drought causing reservoir storage in the Colorado River
system to decline from nearly full to about half of capacity. For
the Lower Basin, a key point has been to maintain the level of
Lake Mead to prevent a shortage declaration.
A healthy snowfall in the Rockies has reduced the odds of a
shortage this year, but the basin states still must come to terms
with a static supply and growing demands, as well as future
impacts from climate change.
On our Lower
Colorado River Tour, April 5-7, you will meet with water
managers from the three Lower Basin states: Nevada, Arizona and
California. Federal, state and local agencies will update you on
the latest hydrologic conditions and how recent storms might
change plans for water supply and storage.
This issue of Western Water examines the ongoing effort
between the United States and Mexico to develop a
new agreement to the 1944 Treaty that will continue the
binational cooperation on constructing Colorado River
infrastructure, storing water in Lake Mead and providing instream
flows for the Colorado River Delta.
As one of the most productive agricultural regions in the world,
the Imperial Valley
receives its water from the Colorado River via the
All-American Canal. Rainfall is scarce in the desert region at
less than three inches per year and groundwater is of little
value.
The dramatic decline in water levels in Lake Mead and Lake Powell
is perhaps the most visible sign of the historic drought that has
gripped the Colorado River Basin for the past 16 years. In 2000,
the reservoirs stood at nearly 100 percent capacity; today, Lake
Powell is at 49 percent capacity while Lake Mead has dropped to
38 percent. Before the late season runoff of Miracle May, it
looked as if Mead might drop low enough to trigger the first-ever
Lower Basin shortage determination in 2016.
