Topic: Hoover Dam

Overview April 24, 2014

Hoover Dam

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.

Changes Loom for Innovative Lower Colorado River Endangered Species Program Amid Drought, New River Rules
WESTERN WATER IN-DEPTH: As the 50-year Multi-Species Conservation Program hits the 20-year mark this month, new questions about how to keep it strong hang over its future

Image shows Endangered bonytail chub were released into a Colorado River lagoon near Laughlin, Nev., in spring of 2024 as part of the MSCP. Before the construction of Hoover Dam on the lower Colorado River, as well as a slew of smaller sisters downstream, the stretch downriver served as a biological oasis in the middle of the unrelenting Mojave and Sonoran deserts. The marshes and backwaters along the river’s edge provided sheltered areas for fish to spawn and rear their young, and mesquite and cottonwood-willow forests provided important habitat for numerous species of birds and other animals.

Los Angeles owns real estate portfolio near Las Vegas

Los Angeles has long funneled masses of tourists to Las Vegas, providing much of the fuel for the casino-heavy economy here. But L.A. also has a more permanent foothold in Southern Nevada. … The Los Angeles Department of Water and Power runs a hilltop lodge in Boulder City and owns another facility nearby for DWP crews who work on transmission lines. It also owns at least 14 acres of land near Henderson’s Lake Las Vegas community and a 2.5-acre plot next to a housing tract in Henderson along Interstate 11, property records indicate. Early last year, Boulder City’s then-City Manager Taylour Tedder told the Review-Journal that he was aware of the lodge but not the DWP operations outpost in his city. … The city of L.A.’s real estate presence in Boulder City may seem random but is far from it, given Los Angeles’ ties to the iconic infrastructure project nearby: Hoover Dam.

WESTERN WATER IN-DEPTH: Tribes hold key state-appointed posts for first time as their water rises in value

A CAP canal in North PhoenixThe climate-driven shrinking of the Colorado River is expanding the influence of Native American tribes over how the river’s flows are divided among cities, farms and reservations across the Southwest.

The tribes are seeing the value of their largely unused river water entitlements rise as the Colorado dwindles, and they are gaining seats they’ve never had at the water bargaining table as government agencies try to redress a legacy of exclusion.

Upper Colorado River States Add Muscle as Decisions Loom on the Shrinking River’s Future
WESTERN WATER NOTEBOOK: Upper Basin States Seek Added Leverage to Protect Their River Shares Amid Difficult Talks with California and the Lower Basin

The White River winds and meanders through a valley.The states of the Lower Colorado River Basin have traditionally played an oversized role in tapping the lifeline that supplies 40 million people in the West. California, Nevada and Arizona were quicker to build major canals and dams and negotiated a landmark deal that requires the Upper Basin to send predictable flows through the Grand Canyon, even during dry years.

But with the federal government threatening unprecedented water cuts amid decades of drought and declining reservoirs, the Upper Basin states of Wyoming, Utah, Colorado and New Mexico are muscling up to protect their shares of an overallocated river whose average flows in the Upper Basin have already dropped 20 percent over the last century.

They have formed new agencies to better monitor their interests, moved influential Colorado River veterans into top negotiating posts and improved their relationships with Native American tribes that also hold substantial claims to the river.

As Climate Change Turns Up The Heat in Las Vegas, Water Managers Try to Wring New Savings to Stretch Supply
WESTERN WATER IN-DEPTH: Rising temperatures are expected to drive up water demand as historic drought in the Colorado River Basin imperils Southern Nevada’s key water source

Las Vegas has reduced its water consumption even as its population has increased. 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.

WESTERN WATER SPOTLIGHT: Draft assessment of 2007 Interim Guidelines expected to provide a guide as talks begin on new river operating rules for the iconic Southwestern river

At full pool, Lake Mead is the largest reservoir in the United States by volume. but two decades of drought have dramatically dropped the water level behind Hoover Dam.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.

Could “Black Swan” Events Spawned by Climate Change Wreak Havoc in the Colorado River Basin?
WESTERN WATER NOTEBOOK: Scientists say a warming planet increases odds of extreme drought and flood; officials say they’re trying to include those possibilities in their plans

Runoff from what some describe as an "epic flood" in 1983 strained the capacity of Glen Canyon Dam to convey water fast enough.  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.

With Drought Plan in Place, Colorado River Stakeholders Face Even Tougher Talks Ahead On The River’s Future
WESTERN WATER IN-DEPTH: Talks are about to begin on a potentially sweeping agreement that could reimagine how the Colorado River is managed

Lake Mead, behind Hoover Dam, shows the effects of nearly two decades of drought. 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 Colorado River Stakeholders Draft a Drought Plan, the Margin for Error in Managing Water Supplies Narrows
WESTERN WATER IN-DEPTH: Climate report and science studies point toward a drier Basin with less runoff and a need to re-evaluate water management

This aerial view of Hoover Dam shows how far the level of Lake Mead has fallen due to ongoing drought conditions.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.

Domino Effect: As Arizona Searches For a Unifying Voice, a Drought Plan for the Lower Colorado River Is Stalled
EDITOR'S NOTE: Finding solutions to the Colorado River — or any disputed river —may be the most important role anyone can play

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.

As Colorado River Levels Drop, Pressure Grows On Arizona To Complete A Plan For Water Shortages
WESTERN WATER IN-DEPTH: A dispute over who speaks for Arizona has stalled work with California, Nevada on Drought Contingency Plan

Hoover Dam and Lake Mead

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.

Meager Snowfall in the Rockies Extends Drought Conditions Along Colorado River
Experts offer updates on latest conditions and forecasts during Lower Colorado River Tour April 11-13

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.

Lower Colorado River Tour 2019

This three-day, two-night tour 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.

The 1,450-mile river is a lifeline to 40 million people in the Southwest across seven states and Mexico. How the Lower Basin states – Arizona, California and Nevada – use and manage this water to meet agricultural, urban, environmental and industrial needs is the focus of this tour.

Despite Above-Average Snowfall in the Rockies, Lower Colorado River Likely to Remain in Drought
Experts will update you on the latest conditions and forecasts during our three-day tour

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.

Western Water Excerpt January 15, 2016 Jenn Bowles

Historic Drought and the Colorado River: Today and Tomorrow
November/December 2015

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.
