Overview

Nevada

As adjacent Western states, California and Nevada share similar issues related to drought and limited water resources. Both states are participants in the 1922 Colorado River Compact and the 2003 and 2007 Quantification Settlement Agreements to allocate Colorado River deliveries. Also, about two-thirds of Lake Tahoe lies in California and one-third in Nevada, and the two states have formed a compact to work together on environmental goals for the lake.

House lawmakers join senators in rallying around Colorado River

A bipartisan coalition of House lawmakers are forming a “Congressional Colorado River Caucus,” with the goal of collaborating on ways to best address worsening drought conditions across the seven-state basin. … [Rep. Joe] Neguse, who serves as ranking member of the House Subcommittee on Federal Lands, announced the creation of the caucus, which will include members from six of the seven Colorado River states: Arizona, California, Colorado, Nevada, New Mexico and Utah. The lawmakers intend to discuss the critical issues affecting the Colorado River, which provides water for 40 million people across the West. Members of the caucus will work “together towards our shared goal to mitigate the impacts felt by record-breaking levels of drought,” according to Neguse.

Nevada considers capping water use in Vegas amid Colorado River drought

Lawmakers in Nevada are considering new rules that would give water managers the authority to cap how much water residents could use in their homes, a step that reflects the dire conditions on the Colorado River after more than two decades of drought. Among the Western states that rely on the Colorado River for sustenance, Nevada has long been a leader in water conservation, establishing laws that limit the size of swimming pools and ban decorative grass. Residents now consume less water than they did 20 years ago.

More moisture is headed to Utah, the West. Will it help Lake Powell?

Lake Powell is currently close to 180 feet below full pool and coming off a summer last year where several boat ramps were closed and owners were advised to retrieve their houseboats from the docks. Releases from a couple of upstream reservoirs, including Flaming Gorge, were made last summer to help the nation’s second largest reservoir and its Glen Canyon Dam, which provides power generation to Wyoming, Utah, Colorado, New Mexico, Arizona, Nevada and Nebraska. A Monday briefing from the drought integrated information center of the National Oceanic and Atmospheric Administration said there is wet relief on the way for Lake Powell, which typically gets its maximum flows well into July.

Las Vegas water agency seeks power to limit residential use

Ornamental lawns are banned in Las Vegas, the size of new swimming pools is capped and much of the water used in homes is sent down a wash to be recycled, but Nevada is looking at another significant step to ensure the water supply for one of the driest major metropolitan areas in the U.S. State lawmakers on Monday are scheduled to discuss granting the power to limit what comes out of residents’ taps to the Southern Nevada Water Authority, the agency managing the Colorado River supply to the city. If lawmakers approve the bill, Nevada would be the first state to give a water agency permanent jurisdiction over the amount of residential use. The sweeping omnibus bill is one of the most significant to go before lawmakers this year in Nevada, one of seven states that rely on the Colorado River.

Has rain helped Lake Mead water levels?

A particularly wet season has swept across the southwestern U.S., a region that has suffered under a severe megadrought for over two decades. But what has this meant for Colorado River reservoir Lake Mead? Storms of rain and snow have hit California particularly badly in recent months, and have spread into neighboring states like Nevada. Reservoirs like Lake Mead rely on seasonal snowmelt and rainfall. Because of the drought, these weather patterns have been less frequent and harder to predict in recent. This means water levels at the largest man-made lake in the U.S., Lake Mead, are rapidly declining.

Was California consulted in recent Colorado River negotiations?

States that use water from the Colorado River are caught in a standoff about how to share shrinking supplies, and their statements about recent negotiations send mixed messages. California officials say they were not consulted as other states in the region drew up a letter to the federal government with what they called a “consensus-based” set of recommendations for water conservation. Leaders in states that drafted the letter disagree with that characterization. The reality of what happened during negotiations may lie somewhere in between, as comments from state leaders hint at possible differences between their definitions of what counts as “consultation.” The squabble is a microcosm of larger tensions between states that use water from the Colorado River.

States struggle to find Colorado River cuts as Lake Mead shrinks

The last time the Colorado River Basin agreed to a set of reductions to address drought conditions and dropping levels at Lake Mead was in 2019. … Now, states are looking to cut far more water than the 2019 agreement yielded, and on a much shorter negotiation timeline. After the seven states that rely on the Colorado River to provide water to roughly 40 million Americans missed two deadlines from the federal government to work out a consensus plan, there are two proposals from the basin states on the table that offer different paths for how to meet the target. The two proposals arrive at a similar number of potential new cuts to water use across the basin, but draw a clear line in the sand between California’s desire to protect its senior water rights, much of which are tied up in the agriculture sector, and the desire of the other six states to have California, Nevada and Arizona share the cuts more equitably.

Southern Nevada Water Authority seeks power to limit water use

While western states work to hash out a plan to save the crumbling Colorado River system, officials from Southern Nevada are preparing for the worst — including possible water restrictions in the state’s most populous county. The Nevada Legislature last week introduced Assembly Bill 220, an omnibus bill that comes from the minds of officials at the Southern Nevada Water Authority. Most significantly, the legislation gives the water authority the ability to impose hefty water restrictions on individual homes in Southern Nevada, where three-quarters of Nevada’s 3.2 million residents live and rely on the drought-stricken Colorado River for 90 percent of their water. … The bill, if approved and signed into law in its current form, would stand as another substantial step toward conserving Nevada’s water …

On this day: The Hoover Dam completed 87 years ago

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.

The water wars of the future are here today

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.

Editorial: Unfair plan to cut California’s Colorado River water use

The immediate question before the seven states that use rapidly vanishing Colorado River water is not how to renegotiate the century-old agreement and accompanying laws that divvy up the supply. California and other states will have to grapple with that problem soon enough, and it won’t be easy. Those accords were hammered out in an era when the Western U.S. was lightly populated, farmland was not yet fully developed and the climate — although few realized it at the time — was unusually wet. Now, when the thirst is greatest and still growing, the region is reverting to its former aridity, exacerbated by higher temperatures caused by global industrialization. But the deadline for that reckoning is still nearly four years off.

Who shoulders Mother Nature’s cut of the Colorado River?

Alongside farmers, ranchers and sprawling urban cities, Mother Nature has long sipped her share of the Colorado River — draining away enough water through evaporation and seepage to support nearly 6 million families each year. But as decades of drought strain major reservoirs in the Mountain West, threatening future water supplies and hydropower, states are divided over who should be picking up nature’s tab for the huge amount of water lost on the 1,500-mile-long waterway. The Upper Basin states — Colorado, New Mexico, Utah and Wyoming — already account for some 468,000 acre-feet of water that evaporates from its reservoirs each year.

Arsenic risk found in wells in Nevada, California, Utah

Tens of thousands of private well owners across parts of Nevada, California and Utah might be drinking water that contains unhealthy levels of arsenic, according to a new study from Desert Research Institute. The study, led by researchers at the institute and the University of Hawaii Cancer Center and published this month in “Environmental Science and Technology,” used data from a previous Desert Research Institute analysis of water from domestic wells in Nevada to build a model to predict which areas have elevated levels of arsenic. The new model showed that more than 49,000 well users across the region are at risk of being exposed to levels of arsenic in their water that could lead to significant long-term health problems.

Thursday Top of the Scroll: As Colorado River shrinks, water evaporation becomes critical to California’s future supplies

Much of the Colorado River’s water is diverted from reservoirs and transported in canals to the farmlands and cities of the desert Southwest. But some of the water also ends up going elsewhere — vanishing into thin air. Water lost to evaporation has become a central point of contention in the disagreement between California and six other states over how to divide reductions in water use. A proposal submitted by Arizona, Colorado, Nevada, New Mexico, Utah and Wyoming calls for relying heavily on counting evaporation and other water losses from reservoirs and along the river in the Lower Basin — the portion of the watershed that begins near the Grand Canyon and stretches to northern Mexico.

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.

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.
