A Dead Sea. The history of one of North America’s most polluted bodies of water.

The United States’ century-old ambition to impound and divvy up every drop of water that could be wrung from its most arid stretches began with a flood. A private firm called the California Development Company (CDC) completed a canal in 1901 that zigzagged across the state’s border with Mexico in order to connect the Colorado River to a dry riverbed that aspiring farmers had already begun to section off for themselves, heeding the proclamation by the newly founded Imperial Valley Press that the region constituted “the most fertile body of arid land on the continent.”

Only two years later, the CDC’s canal was filled with silt, and the customers who had paid up-front for rights to water that could no longer be delivered started filing lawsuits. The CDC dug a new ditch next to the original canal, but in its desperation to act quickly, the company neglected to build any means of controlling how much of the river was diverted into this new channel: If the Colorado flooded, the excess water had nowhere to go but toward the Imperial Valley. To make matters worse, 1905 was an unusually wet year, and by autumn the Colorado was flowing with the same force as Niagara Falls. The CDC’s diversion held, but that only served to funnel the entire river downhill into the valley’s center, a vast salt plain then known as the Salton Sink. It would take two years before the river was contained. Once it was, California had a new body of water, the Salton Sea, almost twice the size of Lake Tahoe.

The Salton Sea was formed before the Hoover Dam, before Lake Powell, before the aqueducts that stretch for hundreds of miles across the West. But there were many more new water features on the horizon: The Bureau of Reclamation, created to develop a “system of nationally-aided irrigation for the arid reaches of the far West,” began building dams across the region in the first decade of the 1900s. It also acquired control of many private water schemes in order to subsidize the price of the water delivered to farmers and residents of the future communities that were being built by urban developers.

The West became dependent on these waterworks as soon as they were constructed, even as their forerunner, the Salton Sea, was slowly transforming into a surreal and toxic landmark. The so-called sea’s salinity began to rise as soon as it was formed, because its water evaporated steadily in the unrelenting sunshine. Over the following decades, the lost water began to be replenished by the runoff from the acres of farms and feedlots spreading across its southern edge. But as the basin was refilling, the runoff was turning the Salton Sea into one of the most polluted bodies of water in the West—a lake that gives off a sulfuric stench of eggs and kills migrating birds by the thousands. The western shore, meanwhile, was littered with detritus from weapons testing by the United States military, and along the eastern shore you could find a tourist town called Bombay Beach that would be all but abandoned in the 1970s after being flooded with runoff. Bombay Beach has since found a second life as an artists’ colony that, starting in 2015, has staged a yearly “biennale” that bills itself as a “renegade celebration of art, music, and philosophy that takes place on the literal edge of western civilization.” But everywhere around the Salton Sea, the shoreline is receding, leaving thousands of acres of polluted playa—the earth that remains after the water has evaporated—which, once it becomes airborne on the wind, produces some of the worst asthma rates in California.

Digging in the dirt: California mining firms seek to clean up lithium’s production footprint

By DW – Made for minds

Three large mining projects based in California’s “Lithium Valley” aim to recover lithium with minimal environmental impacts. They have the potential to simplify the global lithium supply chain.

California’s rapidly shrinking lake is at the forefront of efforts to make the US a major global player in lithium production

About 200 miles (321 kilometers) east of Los Angeles lies the Salton Sea, California’s largest lake by area. It was once a recreation destination and home to a highly productive fishery, but in recent decades the lake has begun to dry up. Now the region has become famous for its most valuable mineral resource — lithium.

Until a decade ago, lithium was mainly used for glass and ceramic production. Now, roughly 70% of lithium is used for batteries. As electric vehicles continue to gain popularity, global lithium demand is skyrocketing.

Last year, US President Joe Biden signed an executive order requiring half of all new cars sold in the United States in 2030 to be zero-emission electric vehicles (EVs). This was seen as a bold step toward reducing carbon emissions, but critics point out that the US isn’t prepared to manufacture electric vehicles at that level. A critical limiting factor is that the US produces very little lithium domestically.

Similarly, the European Parliament approved a mandate that all new car sales need to be zero-emission EVs by 2035. But Europe also depends heavily on imports to meet its lithium demand.

Access to a steady supply of lithium is pivotal for the US’s and Europe’s e-mobility transition, which is why the Salton Sea’s mineral resources have suddenly gained attention.

Top lithium brine deposit

As the edges of the Salton Sea recede, pools of salty, lithium-rich brine are left below ground. In this way the death of the Salton Sea, which is being caused partly by drought conditions worsened by climate change, is becoming part of the solution for mitigating climate change.

Michael McKibben, a geochemist and research professor at University of California Riverside, leads a study analyzing lithium resources in the area.

“I’ve taken both a conservative approach and an optimistic approach to estimating the amount of lithium,” McKibben told DW. “It’s somewhere between 1 and 6 million metric tons of dissolved lithium metal in the brines.” (Or a lithium carbonate equivalent of 5 to 32 million metric tons.)

According to McKibben, that makes this area one of the top lithium brine deposits in the world.

Three companies are racing to tap into this immense lithium resource. If their projects succeed, they will establish a method for extracting lithium without the negative impacts of conventional lithium mining.

The three companies involved are Energy Source Minerals, Berkshire Hathaway Energy (BHE), and Controlled Thermal Resources (CTR). Energy Source Minerals appears to be the closest to their goal. They aim to collect battery-grade lithium at commercial scale by 2024. Berkshire Hathaway Energy has set 2026 as a goal for beginning commercial production. Controlled Thermal Resources has gained investment backing from General Motors.

Don’t call it mining

What sets these projects apart from conventional lithium mining is their connection to geothermal power plants, 11 of which are already established in the area. Geothermal plants pump up hot brine from underground and use the steam to generate electricity before re-injecting the brine back into the ground. Now they will add one more step — removing lithium from the brine before it’s re-injected.

“It’s important not to call it mining,” said McKibben, who prefers the term “lithium recovery,” because compared with conventional lithium mining, this process has minimal environmental impacts.

Conventionally, lithium is extracted in the form of hard rock, or from salts collected in solar ponds.

Hard rock lithium mining involves digging vast, open pits to pull out rocks like spodumene, which then need to be roasted and dissolved in acid. It’s a fossil fuel-intensive process, and has a devastating impact on the local environment. The vast majority of hard rock mines are in Australia, and to a lesser extent, China and Africa.

Salar pond mining involves pumping brine to the surface and leaving it in shallow pools. After the water evaporates, lithium-rich mineral salts remain. Salar ponds, also called salt evaporation ponds, take up thousands of square kilometers and deplete groundwater reserves, especially in desert regions where local populations depend on them. This method is most prevalent in Argentina, Chile and Bolivia.

Compared with salar ponds or hard rock mine pits, a geothermal power plant is relatively small, so direct lithium recovery projects require much less land use. The process avoids both the destruction and waste created by hard rock mining. It has a much smaller effect on groundwater sources than solar pond mining, because brine is re-injected into the ground after its use.

On-site battery production could simplify EV supply chain

In addition to lithium production, there are plans to build battery production factories nearby, which could change the EV battery supply chain on a global scale.

Today the vast majority of lithium is shipped to China to be refined. Refined lithium is then shipped to Japan for cathode production, and cathodes are shipped to the US for battery production.

By manufacturing batteries on-site, the carbon emissions from shipping lithium around the world are cut. Additionally, the US gains the strategic advantage of controlling part of the lithium supply chain, which could be of vital importance if conflicts between China and the US were to trigger sanctions.

Proponents of the project say that battery manufacturing plants would create thousands of jobs in a county that currently has an unemployment rate which is three times higher than the US average. Also, these projects will amount to significant income for the state of California, due to a recently approved tax on lithium production.

The beginnings of a clean lithium revolution?

Internationally, other projects are developing similar processes for use in other regions. Lake Resources is developing a project in Puna, Argentina, and Vulcan Energy Resources is working to bring the process to its geothermal power plants in Germany.

“We are very familiar with the developments in California,” said Horst Kreuter, CEO and founder of Vulcan Energy Resources. “Our technical director for lithium extraction was involved in lithium extraction in California in a leading role for over six years” he told DW.

Vulcan Energy aims to begin commercial production of lithium in Germany by 2024-2025.

If these projects prove successful, a path to cleaner lithium production may be just around the corner.

Lake that predated Salton Sea came and went as the Colorado River changed course

By Thomas Fudge / Science and Technology Reporter -kpbs

U.S. Bureau of Reclamation – This undated map of the Salton Sea basin shows the shape and size of a full Lake Cahuilla as indicated by the dotted red line.

Before the Colorado River was tamed by dams and dikes it was a free flowing, flooding river that often changed course, sometimes dramatically. Though it typically flowed south to the Gulf of California, in years of powerful floods it would flow into the Salton Sea Basin, and fill it up to form what we call Lake Cahuilla.

Since about 612 B.C. Lake Cahuilla has filled up seven times, the last time in 1733. The flooding Colorado would create a huge lake that stretched from what’s now Palm Springs, California in the north to well beyond Mexicali, Mexico in the south.

Thomas Rockwell is a geology professor at San Diego State who examined charcoal and other organic matter to determine when the lake filled and receded.

“Before we dammed up the Colorado River, the Colorado River would flood, seasonally. And during six of these periods in the last 1,100 years, the Colorado flowed, unabated, into the Salton trough, and filled Lake Cahuilla to an elevation of about 40 feet,” said Rockwell.

Rockwell adds that when it filled with Colorado River water the lake would be 100 meters deep at its deepest part and, as Rockwell says, it would have an elevation of 13 meters (40 feet) above sea level. It would dry up when the Colorado reset its course toward the gulf of California.

The study sheds light on the human relationship with the land. Rockwell says archeological evidence shows how American Indian populations adapted to the changing lake.

“You had various Native American communities, the Cocopah, the Cahuilla, that would live along the shoreline and fish when the water was high. The Cahuilla are known historically to farm the bottomlands when the lake wasn’t there,” he said.

The Salton Sea Basin is at the southern end of the San Andreas Fault. Rockwell said his ulterior motive, as a geologist, was to study the history of earthquakes in the region.

“Now that we have this high resolution study of lakes, we’re putting together a high resolution study of earthquakes for the last 1,100 years,” Rockwell said. “Most of the earthquakes on the southern San Andreas fault occurred while the lake was full.”

He said the weight and the pressure of a full Lake Cahuilla would weaken the strength of an earthquake fault, making it more likely to fail.

The Salton Sea was created in 1905 when the Colorado River breached a dike and flooded part of the basin. What some view as a technical failure of flood control, Rockwell sees as a natural occurrence, given the history of Lake Cahuilla.

When asked what he thought of efforts to maintain the Salton Sea, which has been sustained through farm runoff, Rockwell said he understands the importance of the Salton Sea to migratory birds. But in its natural state, he said the Salton Sea would be entirely dry today.

 

 

County Contract with Engineering Firm Sets Salton Sea Project in Motion

Source: MynewsLA.com

Riverside County supervisors Tuesday approved a $4.12 million contract with an Encinitas-based firm to provide engineering and design services for a project to revitalize a portion of the dying Salton Sea.

“We’ve been working on this project for several years now,” Salton Sea Authority Executive Director Patrick O’Dowd told the Board of Supervisors. “It’s a big day for the community of North Shore and a big day for Riverside County.”

The two-year agreement with Dudek Consulting formally marks initiation of the Salton Sea North Lake Pilot Demonstration Project, conceived four years ago.

Salton Sea

“With the Salton Sea, there have been lots of studies done over the last four or five decades,” said board Chairman Jeff Hewitt, who sits on the Salton Sea Authority Board. “There have been lots of things where hands went up in the air, so it’s great to see something happening where they’re going to be moving some dirt in a good way.”

Supervisor Manuel Perez, whose Fourth District encompasses the north end of the Salton Sea, pointed out that roughly $19 million in Proposition 68 funds have been allocated for the project. Prop 68 was approved in 2018 as the California Drought, Water, Parks, Climate, Coastal Protection & Outdoor Access for All Act.

“More money is coming,” Perez said. “We’re working with our legislators to do what’s best. This is going to bring economic development, jobs, trailways and parks. People want amenities.”

The North Lake project was first discussed in 2018 and was ultimately incorporated into the larger revitalization effort, which envisions maintaining and improving segments of the 360-square-mile lake in Riverside and Imperial counties.

Salton Sea Contamination

According to documents posted to the board’s agenda, the North Lake project entails establishing 156 acres of shallow and deep marine habitat. About one mile of shallow water is slated to run along the sea’s north shoreline.

The Dudek contract anticipates jack and boring operations under Highway 111 and the acquisition of properties — probably 10 parcels — to serve as easements for a pipeline that could deliver 1,900 to 2,600 acre-feet of water to the lake annually.

Berms would need to be constructed, along with new utility access points and rights-of-way, according to county documents.

Recreational boating and fishing would be part of the new lake.

The contract stipulates that a range of analyses will have to be completed, assessing environmental impacts and other feasibility issues.

In October 2019, the board authorized formation of the Salton Sea Enhanced Infrastructure Financing District, though the concept awaits voter approval.

EIFDs were authorized under Senate Bill 628 in 2014 and permit bond sales to finance construction of private and public projects.

The sea has been allowed to erode to the point of eutrophication, killing off animal and plant life because of extreme salinity. An east wind in September 2012 created conditions for a sulphuric stench that wafted across Riverside County into the Los Angeles Basin. The overpowering odor lingered for hours.

Dust clouds kicked up on parts of dry lake bed have raised other health concerns.

The South Coast Air Quality Management District monitors the area and periodically issues odor and other advisories.

Water reclamation by local agencies and Mexico, plus the loss of Colorado River supplies that originally fed the Salton Sea, have caused water levels to drop and salinity to spike.

WATER 101: A Recap of Where We Are Amidst a Historic Drought

I Imperial Valley— Local farmers may soon be forced to bite the bullet and find ways to use significantly less water in 2023 — potentially for a lot longer.

This drastic measure may come as a result of an emergency water conservation effort to prevent further depletion of the Valley’s main source of water, the Colorado River. If less water flows down the Colorado River, the consequences could be catastrophic for the two reservoirs — lakes Mead and Powell — that feed into the so-called basin states.

For example, if water levels in Lake Mead continue dropping, it could bring water and hydropower to a grinding halt, all due to a relentless drought over two decades.

Measuring Water

The Imperial Irrigation District, the largest water agency in California, is nearing final negotiations with Arizona — one of the lower basin states — to see how much water each state will be able to conserve. And the bar is high.

In June, the federal Bureau of Reclamation requested the states, water agencies and Native tribes along the Colorado River basin to propose ways to collectively conserve up to 4 million acre-feet of water in 2023. They must all reach a deal by mid-August.

How this will impact the farmers who rely on the Colorado River to grow their crops and sustain the principal economic engine of the Imperial Valley can perhaps be better understood through the various ways the Imperial Irrigation District distributes water throughout the region, and how farmers make do with a persistent drought that seems to have no end.

Measuring Water

How much is an acre foot of water?

Water, in general, is measured by the acre-foot, meaning that one acre-foot covers an acre of land one foot deep. One acre-foot of water equals about 326,000 gallons, enough to supply a family of four or five for one year.

How much does the Imperial Valley get?

The IID is allocated 3.1 million acre-feet of water, of which some 500,000 acre-feet of water are transferred to other agencies including the Metropolitan Water District, San Diego County Water Authority, and the Coachella Valley Water District.

The remaining 2.5 million acre-feet of water are then distributed to farmers, residents and businesses throughout the Imperial Valley each year.

How much of it goes to farmers and how much to residents?

Of the 2.5 million acre-feet of water that does get distributed within the Imperial Valley, some 21,631 acre-feet of water is distributed to industrial and commercial users while some 32,580 acre-feet of water is distributed to residents.

In short, 97.8 percent of water goes to agriculture while just over 2 percent goes to residential, industrial and commercial users.

Plans to Import Water to the Salton Sea Seek Approval

NBC PALM SPRINGS By Ceci Partridge

 

SALTON SEA PLAN

The Salton Sea Independent Review Panel has 3 viable ideas to restore the Salton Sea.

In a press release, the Independent Review Panel announced that there were 18 concepts submitted through “Request for Ideas” in 2017 and 2021. Of those 18 ideas, three made it to the top of the list. And one is to import water from the Sea of Cortez, a large body of water in Mexico.

“One of the options is to import water from out of the basin to restore sea level and also to reduce the salinity of the sea, which is now about twice the salinity of the ocean,” said Brent Haddad an investigator with UC Santa Cruz.

The panel conducted a Fatal Flaw Report to assess the feasibility of the top 3 ideas.

The Fatal Flaw report included 5 attributes that no viable approach to water should have, according to the panel.

These flaws include technology reliability, achieving restoration goals, not harming nearby protected habitats, minimizing risk of catastrophic flooding, and long-term project viability.

The report is the second of four reports to address sourcing water to the Salton Sea.

The full press release from the Independent Review Panel can be found by clicking here.

The Salton Sea Independent Review Panel consists of seven experts in different aspects of water-body restoration. The Panel is led by Panel Chair, Dr. Rominder Suri. Dr. Suri is Professor and Chair of the Department of Civil and Environmental Engineering at Temple University, and founding director of Temple University’s NSF-funded Water, Environment, and Technology (WET) Center.

Senate Advances Feinstein, Padilla Bill to Improve Salton Sea Air, Water, Wildlife Quality

Committee also advanced two of their bills to preserve public lands, natural resources, and historic sites

Washington—Senators Dianne Feinstein and Alex Padilla (both D-Calif.) applauded the Energy and Natural Resources committee for advancing their Salton Sea Projects Improvements Act, which would increase federal investment in ecological improvement projects at the Salton Sea and significantly expand federal partnerships with state, local and Tribal governments to address the public health and environmental crises at the Salton Sea.

“For years the Salton Sea has been receding, threatening the local ecosystem and creating toxic dust clouds that are harming the surrounding communities,” said Senator Feinstein. “The Energy and Natural Resources Committee advanced our bill that will make it easier for every level of government to work together to address the problem and provide the resources necessary to protect public health and restore vital habitat.”

“The environmental and public health crises at the Salton Sea have been neglected for too long, and it’s wreaking havoc on the environment and surrounding communities,” said Senator Padilla. “As the climate crisis continues to exacerbate the worst megadrought in over 1,200 years, and as the Bureau of Reclamation is asking states to conserve more Colorado River water supplies, now is the time to ensure that the federal government has the strongest tools to mitigate devastating impacts from the increasingly exposed Salton Sea lakebed. Importantly, my bill with Senator Feinstein and Representative Ruiz will better enable the federal government to advance environmental justice and protect the public health of the disadvantaged communities surrounding the lake. I’m glad to see this bill advance out of committee and I look forward to continuing to build momentum to pass this in the Senate.”

Salton Sea

“We need more action to address the pressing environmental and public health crisis at the Salton Sea,” said Dr. Ruiz. “My bill with Senators Padilla and Feinstein, the Salton Sea Projects Improvements Act, urgently opens up more resources and adds more flexibility to add more shovels to the ground on projects that protect the public’s health. I am impatient with our progress and will never stop working to strengthen our all-hands-on-deck approach to the environmental hazard at the Salton Sea.”

“We are excited to see this bill move forward to enable critical federal investment in improving conditions at the Salton Sea,” said California Secretary for Natural Resources Wade Crowfoot. “This adds to a growing sense of momentum as the state’s Salton Sea Management Program works with local, Tribal and federal partners to break ground on projects around the sea to deliver on our commitments and advance environmental justice and equity for the region in the face of climate change.”

“I applaud Senators Padilla and Feinstein for moving this key legislation forward in the Senate to increase Bureau of Reclamation funding for the Salton Sea,” commented Salton Sea Authority Executive Director G. Patrick O’Dowd. “Last month, the Commissioner testified that she seeks major cuts to California’s Colorado River water supplies which would significantly impact the disadvantaged and tribal communities surrounding the Salton Sea,” O’Dowd continued. “The senators’ legislation is an important tool in the toolbox to help Reclamation meet its obligation to assess, fund and implement its own Salton Sea mitigation projects to address those federally-imposed impacts.”

“The Salton Sea Improvements Act is a huge step forward for the Sea and we thank Senator Padilla and Senator Feinstein for their efforts to move this legislation forward,” said Frank Ruiz, Audubon’s Salton Sea Program Director. “For decades, Audubon has dedicated time and resources to drive conservation efforts at the Sea and protect the birds and people who rely on this fragile ecosystem. We support this additional federal attention to bring solutions to the Sea and we urge swift passage of this bill.”

The committee also advanced the Berryessa Snow Mountain National Monument Expansion Act, the Rosie the Riveter National Historic Site Expansion Act and the Rim of the Valley Corridor Protection Act. The Berryessa Snow Mountain National Monument Expansion Act would add an adjacent 3,925 acres to the current Monument, support tribal co-management and change the name of the additional wildlands from “Walker Ridge” to Molok Luyuk—Patwin for “Condor Ridge”—a name the Yocha Dehe Wintun Nation provided. The Rosie the Riveter National Historic Site Expansion Act would add Nystrom Elementary School to the existing Rosie the Riveter/World War II Home Front National Historical Park in Richmond, CA and authorize the National Park Service to add other historically relevant sites to the park’s boundaries. The Rim of the Valley Corridor Protection Act would add more than 191,000 acres of the Rim of the Valley Corridor to the Santa Monica Mountains National Recreation Area.

“I am so proud to represent the Richmond community and to work in Congress to ensure its contributions during WWII are recognized,” Congressman DeSaulnier said. “By preserving Nystrom Elementary School as part of the historic park, we honor the sacrifices made by the Rosies in Contra Costa County who worked on the home front and we help preserve their legacy for future generations.”

“Conserving California’s special places has been a lifelong passion throughout my tenure in the state legislature, as Deputy Secretary of the Interior to President Clinton, and now as a member of Congress representing Lake County. I introduced the ‘Berryessa Snow Mountain National Monument Expansion Act’ in the U.S. House of Representatives to protect and expand the national monument, and I applaud Senators Alex Padilla and Dianne Feinstein for championing this legislation in the United States Senate,” said Congressman John Garamendi.

“Back in 2016, I worked to designate the Berryessa Snow Mountain region as a National Monument,” said Congressman Mike Thompson. “Earlier this year, I was proud to join Rep. Garamendi to expand this designation and protect more of our pristine public lands. The Berryessa Snow Mountain National Monument is crucial for protecting the biodiversity of the land and boosting our economy through recreational opportunities. I am glad the Berryessa Snow Mountain National Monument Expansion Act is being taken up in the Senate, led by Senators Feinstein and Padilla, and I look forward to seeing it signed into law by President Biden.”

“Molok Luyuk – or Condor Ridge – is a special part of Northern California and deserves special protections. We appreciate Senator Padilla and Feinstein’s leadership on this and their insistence that Native American voices be part of the conversation,” said Chairman Anthony Roberts of the Yocha Dehe Wintun Nation. “Our ancestors traveled and traded there for centuries. With these protections, the unique resources on Molok Luyuk will endure, and Californians will be able to enjoy its natural beauty for generations to come.”

We are thrilled to see this legislation pass through the senate and grateful to the leadership of Senators Padilla and Feinstein in the work to expand Berryessa Snow Mountain National Monument,” said Sandra Schubert, Executive Director of Tuleyome.“Molok Luyuk is a treasure. As neighbors we have long appreciated its natural beauty, diverse wildlife, rare plants, and indigenous cultural value. This is exciting progress in the effort to protect Molok Luyuk from current and future threats while respecting Tribal stewardship over the lands.”

Efforts underway to replenish dying Salton Sea in Imperial Valley

 

It was once called the Salton Riviera and a miracle in the desert.  The Salton Sea is different now; dead fish, decaying area, foul odor , and dangerous toxic fumes. It’s a wasteland.  Once California’s largest lake, now it’s on the verge of extinction, many claiming it is beyond repair.  Rodney Smith PhD., Managing Partner of the Sea To Sea Bi-National Canal Co., joined KUSI’s Logan Byrnes on “Good Evening San Diego” to discuss how he will save the dying Salton Sea.  Smith has a plan called SEA TO SEA where he wants to build a channel from the Sea of Cortez to the Salton Sea at a cost of 1.2 billion dollars.  This would be the first effort to review the tragedy and utter incompetence of the State on this issue.

Importing water to save the Salton Sea is long overdue. What are we waiting for?

the Salton Sea is drying
the Salton Sea is drying
Feliz Nunez Special to The Desert Sun

For various reasons, the Salton Sea is drying: rural-urban water transfers and sales, drought and manmade pollution. We have local water scarcity and poor-quality air. Due to urban population explosions, some of the Colorado River water that once went into the Salton Sea is now being sold to the Coachella Valley Water District, Los Angeles and San Diego. The Salton Sea is drying at a faster speed as temperatures rise and there is less water flowing into it. If we are to reverse the situation, this will demand decreasing water use and increasing the cost of water.

As the Salton Sea dries, air pollution rises as there is more dust, and it emits more stench in the form of hydrogen sulfide gas.  Waste and chemicals coming from the Imperial Valley, together with Mexicali’s population explosion, are an overwhelming septic cargo for outdated infrastructure. Wastewater plants that have not been updated allow raw sewage and industrial chemicals to escape into the Alamo and New Rivers. These so-called rivers drain additional pollutants into the Salton Sea. Beneath the shrinking lake lie other pollutants: munitions from the World War II era, tons of pesticides, fertilizers and organic dead matter, which when exposed to the air release carbon dioxide and methane.

Dust at Salton Sea

Owens Lake in Northern California became a disastrous dust bowl when the city of Los Angeles built a 200-mile aqueduct and completely drained the lake. This lifeless northern California site stretches for miles, with a patchwork of dust-control projects like furrowing, covering the lake bottom with gravel, plantings, and sprinkler systems costing $2.5 billion to install. There are millions more in maintenance costs every year.

Officials at the Salton Sea are following the Owens Lake path. Their ongoing practice of digging furrows and shallow ponds to control dust as more and more lakebed is exposed is questionable. Not only are these methods ineffective, they cause more greenhouse gas emissions!  The Salton Sea is three times bigger than Owens Lake, so following that path could cost an estimated $7.5 billion.

Politicians and state officials who favor using the “incremental approach” with patronizing dry measures and shallow-water fixtures have succeeded in the serial killing of fish and other wildlife, and we are heading toward ever-more inhospitable conditions for humans. Importing ocean water would immediately address respiratory ailments, reverse the effects of drought and curb pollution. But the high cost is the main argument against water importation. In my view that expense is worth it. Yes, it will cost money to be a community that respects and takes care of our air, water, and soil.

Unlike Owens Lake, the Salton Sea has two oceans close by; there are 13 proposals to build an aqueduct to import water — either from the Sea of Cortez or the Pacific Ocean. Leaders of the Salton Sea Management Authority have considered these proposals too costly. However, a feasibility study is now being conducted by UC Santa Cruz to evaluate the effectiveness of these plans to import water. Their report will be turned over in September to the Salton Sea Management Program’s Long Range Planning Committee.

It is uncertain if water Importation will pass the feasibility test. If passed, how much longer will it take to start the engineering for an aqueduct?

The engineering of water importation should have started with the 2003 Quantification Settlement Agreement that legalized redirecting Colorado River water away from the Salton Sea. The QSA also called for restoring the largest lake in California, the Salton Sea. What are we waiting for?

Commentary: How the Salton Sea Came to Be Viewed as a ‘Lost Cause’

The Missing Link in the U.S. EV Supply Chain
Salton Sea.
Many view the Salton Sea as an ecological disaster, or a wasteland. This public perception, which is bound up in environmental racism, continues to undermine conservation efforts.

The Salton Sea is a place of stunning contradictions. For decades, Californians have tried to figure out what to make of it. Often described as a “man-made” or “accidental,” the Salton Sea formed between 1905 and 1907 when the Colorado River overflowed from an irrigation project into a deep bowl in the desert floor in present-day Imperial County.

Settlers described this flooding as an unprecedented disaster, but soon found a purpose for the sea as a receptacle for runoff from Imperial Valley farms. During the 50s and 60s, the sea became a popular tourist attraction, but rising water from increased irrigation flooded its hotels and resorts, driving the tourists away. Rumors about the health effects of swimming and angling in the pesticide-contaminated water also influenced the decline of the resorts.

Salton Sea included in $172 million in funding for ports and waterways projects
Salton Sea

In 2003, the Imperial Valley transferred its Colorado River water rights to San Diego, and the Salton Sea, which had been sustained by runoff from the valley for most of the twentieth century, lost much of its inflow. As the sea started to shrink, it released pesticides and other toxins leading to massive fish and bird die-offs over the course of two decades.

My recent book explores how, at different times viewed as a disaster, a sump, and a health resort, the Salton Sea came to be commonly viewed as a wasteland. Policymakers struggled to raise funds—and popular support—for the sea’s conservation. The area around it, subsequently, has been used for the kinds of industrial projects reserved for places held in low regard: mines, prisons, and military bases.

The Salton Sea wasn’t just an accident, despite its reputation as the result of engineering mistakes made by early settlers. In fact, it is the most recent example of a natural cycle of Colorado River overflows that have filled this part of the desert for thousands of years. Floods from the Colorado River have been big and small—vast inundations that resulted in water bodies like Lake Cahuilla and relatively small overflow pools that evaporated within months.
