The flip side to Colorado River conservation? A drying Salton Sea
That’s because the Salton Sea is filled primarily by agricultural runoff from farms in the Imperial Valley in far Southern California. Those farms have a single source of water: the Colorado River.
The Salton Sea is a landlocked, shallow lake in Riverside and Imperial counties. The lakebed has been contaminated for more than 100 years with pesticides and other chemicals that create dangerous air pollution for surrounding communities.
Balancing conservation with the impact on the Salton Sea is a long-running conundrum.
“It feels that we are responsible for conserving the Colorado River for the good of the many,” said Silvia Paz, director of grassroots group Alianza Coachella Valley, which is working to address the impacts of pollution from the Salton Sea.
“And on the flip side, I don't think it's fair that one particular community that's already an environmental justice community has to bear that responsibility — almost alone it feels like,” Paz said.
A brief history of the Salton Sea
The Salton Sea is part of the massive Colorado River delta. For millennia, the area flooded periodically as the river shifted across the sandy delta region spanning across present-day Southern California, southern Arizona and northern Mexico.
Lake Cahuilla is some of the last evidence of that era of flooding before the river was controlled and diverted via dams and canals. Today, the river no longer meets the sea.
The Salton Sea as we now know it is California’s largest lake. And it's man made. It was first created back in 1905, when an irrigation canal gate failed and the river flooded into the historic lakebed of Lake Cahuilla.
Since then, the sea has been fed by agricultural runoff. Once a popular vacation destination in the 1950s, as farmers got more efficient with water use and climate change-driven heat worsened, the lake — and its tourists — has been drying up, and the lakebed has become increasingly exposed.
Though it’s saltier than the ocean, the Salton Sea remains a biodiversity hotspot for fish and migratory birds.
Conservation to save the Colorado River
Imperial Valley farmers in Southern California use more Colorado River water than anyone. They grow primarily hay as well as leafy greens and other produce that feeds much of the country and the world.
In August, the Imperial Irrigation District agreed to a major new deal with the federal government to cut its water use by an amount that’s more than double the amount the entire state of Nevada uses in a year. The cuts will happen through 2026.

And they're needed: Two wet years have helped, but the risk of Lake Mead reaching deadpool — meaning the water level has dropped so low that it can no longer flow downstream — remains a looming possibility. That could cut off the main water supply for tens of millions of people and farms downstream.
The first phase of this new program started this summer, and included a program where participating forage crop growers didn’t water those crops for 49 days, during the hottest part of the year. The main crop grown in the Imperial Valley is alfalfa.
Lake Mead, the largest reservoir in the nation, had shrunk so low in 2022 there were concerns it'd reach deadpool, cutting off hydropower and water to millions downstream.

In return, the Imperial Irrigation District got $589 million from the feds to pay those farmers who can then invest in more water-efficient technologies, pay workers, or otherwise invest in their farms.
The program was a success, said Tina Shields, the Imperial Irrigation District’s water manager. She said the district cut water use by about 175,000 acre-feet this summer. For comparison, the entire city of L.A. uses about 500,000 acre-feet of water every year.
The short duration of the program had little impact on the economy. If anything, it helped farmers stay in business because hay markets are bad right now — that’s a reason why so many farmers participated this summer, Shields said.
Plus, water use in the area is down in general because October has been abnormally hot, so watering would just burn crops.

He participated in the Irrigation District's recent conservation program where he didn't water his crops during the hottest time of year. He said the program helped keep his business going during tough times, while saving water.

The consequences of conservation
Since that program ended at the end of September, the surface elevation of the Salton Sea has dropped about 10 inches and the sea shrunk by some 3,500 acres, exposing more dust from the lakebed, said Paz, whose group along with researchers from UCLA and the Pacific Institute measured the decline.
“Our communities don't have the luxury to escape the dust that is blown into the air,” Paz said. “Siloing this issue as a water-only issue leads to all these other consequences.”
A study by UC Riverside found that the Salton Sea’s rotting odors have become a yearlong nuisance for people living near the lake due to shrinking levels.

In its review, the federal government found the new agreement with the Imperial Irrigation District, or IID, would have no significant new environmental impacts to the Salton Sea and surrounding communities. But many people in the area disagree.
“The reality is that, for our communities, it's not a negligible impact,” Paz said. “This is a cumulative impact to the conditions that we're already suffering.”

Who's responsible for the Salton Sea?
Those impacts are why the Sierra Club recently sued the IID about the conservation deal. The organization says the district did not do a proper environmental review of the impacts to the Salton Sea and nearby communities.
“We believe that they should be paying the bill for some of the impacts,” said Richard Miller, director of the Sierra Club’s San Diego chapter.
The IID argues it's already done it's part to address the issues caused by a drying Salton Sea. Shields said the district only agreed to this recent round of additional conservation efforts because they negotiated that $250 million in federal dollars would go towards accelerating the state’s Salton Sea efforts.

“That funding is conditioned on IID implementing these additional conservation efforts,” Shields said. “So we up front took care of the Salton Sea from our perspective.”
But it’s the state that is primarily responsible for addressing the pollution impacts of a shrinking Salton Sea. They are behind on their 10-year plan, which aims to restore nearly 30,000 acres by 2028 of exposed lakebed to native desert habitat and man-made ponds that support endangered fish, migratory birds and reducing pollution.
In recent years, restoration efforts have accelerated, in large part thanks to that $250 million in funding from the Biden-Harris Administration, said Miguel Hernandez, a spokesperson for the state’s Salton Sea Management project, in a statement to LAist.
He wrote that, so far, the state has completed more than 2,000 acres of habitat restoration and dust control, with some 6,500 acres currently under construction and major construction complete for a 4,100-acre conservation area — additional federal funding is helping to expand that project by 750 acres.

“IID is doing the right thing conserving water to stabilize the Colorado River, and our federal partners stepped up to provide funding for this water conservation and for California’s ongoing projects at the Sea to reduce dust emissions and restore habitat,” Hernandez wrote.
But Paz said the sea is shrinking faster than projects are being built to cover the exposed lakebed.
“We need to balance this out. They need to move a lot faster,” Paz said.

What’s the solution?
Everyone agrees the ongoing restoration efforts are key to addressing the impacts of a shrinking Salton Sea. But balancing necessary conservation with the impacts of that conservation can seem like an impossible problem to solve.
“It’s the rock and a hard place,” said Shields. “As we get more efficient, the downside is the Salton Sea has less water. It's a tough thing with an inland body of water that has no outlet and the only inlet is receiving drainage water from the adjacent areas. So it's a balancing act to keep everybody happy.”
It’s the rock and a hard place.
— Tina Shields, water manager for Imperial Irrigation District
Shields continued: “But if the Colorado River crashes, that's not something you just fix the next year,” So we're going to do everything we can to ensure that our communities have a reliable and safe water supply. And it may be that there are impacts to the Salton Sea, but without the Colorado River, there would be no Salton Sea.”
Paz said she supports and understands the conservation needs, but that means that policymakers and water managers need to think more holistically about the mitigation efforts.
“If this is the only way, we need to broaden how we think about how we’re protecting and preparing our communities,” Paz said.
She said accelerating the state's restoration projects is essential, plus funding for air filters and weatherizing more homes, particularly mobile homes that house farmworkers, for which funding is lacking, she said.

But Paz said mitigation for conservation impacts to the Salton Sea could go beyond direct impacts, to improving general quality of life, especially as desert communities face some of the quickest accelerating impacts of the climate crisis.
One example? A new plan envisioned by the community and supported by local governments to build a commuter rail line connecting all the Coachella Valley communities, that will also add green space, shade and an emergency shelter to help communities ride out disasters and excessive heat.
“We’re talking about being very mindful of how our built environment is being developed to address the needs that we have, particularly when it comes to climate resilience,” Paz said.
She added that funding from Proposition 4, which is on the November ballot, would help speed up some existing efforts.
“We're very hopeful that Proposition 4 gets support statewide and that that funding will become available,” Paz said. (Update: Voters did indeed pass that proposition).

As for the state’s plan, it’s estimated it will cost more than a billion dollars to complete the necessary habitat restoration and dust mitigation efforts.
Among other things, a large chunk of the $250 million from the Biden Administration’s Inflation Reduction Act will go towards a more than 4,000-acre restoration area to plant habitat that supports migratory birds and reduces dust pollution, said Mike Lynes, public policy director for Audubon California. Other ongoing projects are showing preliminary promise.
“We cannot lose our hope,” said Paz. “Transforming our communities takes a lot of work, but at the end of it, this is a work of hope and that is what allows us to keep envisioning and to keep trying. Because I believe that a different future is possible.”

Are L.A. County Superior Court judges setting higher bail for Latino defendants? Some court-watchers say yes, according to a new report.
What does it cover? Between January and November 2025, La Defensa’s Court Watch LA volunteers observed 140 random criminal cases that included felonies and misdemeanors.
What did they find? The report details multiple findings, including that defendants who appeared to be Latino had an average bail amount more than 15 times higher than white defendants.
How accurate is this? This is a sample from over 200,000 cases. It’s based on human observation, so the organizers acknowledged that there are gaps. But they’ve asked the court to share its own data, which they say they have not received.
Read on…. to see the L.A. County Superior Court’s response.
A criminal justice watchdog is calling into question whether Latinos in the L.A. County Superior Court get a fair shot at bail.
The new report from the nonprofit La Defensa, which advocates for reform in the legal system, analyzes a sample of pretrial decisions from 2025 which had been documented by community court-watching volunteers.
One of the key findings was that defendants who were perceived to be Latino had an average bail amount of $157,700 — more than 15 times higher than white defendants and nearly three times higher than Black defendants.
Studies show that inability to pay bail can affect defendants’ livelihoods and their ability to defend themselves, according to the Vera Institute of Justice.
“ Most families — no matter what they did, no matter what they sold — cannot actually purchase that person’s freedom to give them the fighting chance to go against the state,” Titilayọ Rasaki, La Defensa’s state policy and legal affairs director.
The L.A. County Superior Court says it’s following the law on bail requirements and that the findings are missing context because observation is limited.
How court-watching works
La Defensa’s Court Watch LA program is a community-led effort to document and hold the courts accountable. They train volunteers to go in and observe cases.
The volunteers take notes on the charges, the judge’s conduct and the person’s criminal history, if it comes up. That then gets analyzed against publicly available case information and state law. Programs like this exist in several other cities around the country.
For the latest report, La Defensa volunteers observed 140 felony and misdemeanor criminal cases, chosen at random, between January to November 2025.
Judicial accountability lead Bryanna Siguenza explained how she decided where to send the volunteers.
“ I choose a department, specifically ones that are pretty busy, have high case loads, and are arraignment and pretrial,” she said.
What watchers saw
Racial disparities in pretrial settings have been researched at local, state and national levels, but La Defensa’s findings are based entirely on human observation, Siguenza said.
The volunteers are trained to listen for important details that come up in proceedings, but they may not always get the full story behind the charges, like a defendant’s criminal history.
L.A. County Superior Court spokesperson Rob Oftring said the report needs more context.
“Many of the report’s findings, for example, do not appear to account for charge severity or criminal history, both of which are legally significant factors in any release decision…” he wrote in a statement.
La Defensa did not include in its report what charges had been filed in the cases observed. However, according to the report, comparable charges still had disproportionate bail outcomes that “couldn’t be explained by charge severity alone.”
The severity of charges legally informs bail decisions. The Superior Court is required to have standard bail amounts based on the crime, which judges have discretion to adjust.
State law also requires judges to weigh issues like public safety in bail decisions, as well as the defendant’s ability to post bail. According to the volunteers’ observations, the judges considered the latter in just a quarter of cases when setting bail.
Oftring said the court has taken steps to reduce money bail’s usage as allowed by law.
“Bail at arraignment is set only after both the defense and prosecution have been heard and the judge has weighed the specific facts of the case,” his statement read.
The limits of the findings
Oftring said the court values the role organizations like Court Watch LA play in keeping the justice system accountable, but that the sample size of the researchers used in their report is too small to draw any definitive conclusions.
Roughly 272,000 criminal cases took place during that time period, according to Oftring.
Representatives from La Defensa said they know the report is only a snapshot of the system, and that human observation has its limits.
That’s why in November, they requested 10 years of de-identified data to analyze whether bail outcomes differ across judges, courthouses and demographic groups. Rasaki said they haven’t received it.
“ We would say release the data … by all means, we want to partner. We want to analyze,” she said.
Oftring told LAist they are working on several projects that “provide data-informed scrutiny of how the court operates.”

The National Weather Service has issued a heat advisory for much of Southern California through Monday. Some places are also under more severe heat warnings.
The details: Highs in the San Fernando Valley, San Gabriel Valley and other inland areas of L.A. County are expected to range from the mid-90s to about 105 degrees. Downtown Los Angeles and much of Orange, Ventura and Santa Barbara counties will get up to the lower 90s. Parts of the Inland Empire could get up to 108 degrees and the Coachella Valley could hit 120.
Wildfire risk: Forecasters warn that fire danger will be elevated through at least Monday, driven by heat, dry vegetation and low humidity levels away from the coast. Despite some extra moisture in the air over the last several weeks, there hasn’t been enough to actually produce rain.

Southern Californians are in for yet another scorching weekend.
The National Weather Service has issued a heat advisory for much of the region through Monday, with temperatures expected to hit their peak on Sunday.
Highs in the San Fernando Valley, San Gabriel Valley and other inland areas of L.A. County are expected to range from the mid-90s to about 105 degrees. Downtown Los Angeles and much of Orange, Ventura and Santa Barbara counties will get up to the lower 90s. Beaches will also be hot — in the lower 80s.
Moving farther east, things get really toasty. Forecasters have issued a more severe extreme heat warning for parts of the Inland Empire, where temperatures could get up to 108 degrees, and for the Coachella Valley, where they could hit 120.
Humidity will likely also continue to add to the discomfort, but will be concentrated in areas closer to the coast, where it will keep nighttime temperatures relatively warm and make it more difficult to cool down. Inland areas will feel drier.
Those who are most at-risk from the heat are people who work or spend time outside, people without access to air conditioning and those who are either over 65 or young children.
Making sense of heat forecasts
Southern Californians are no strangers to hot weather in the summer, but heat waves are getting hotter, longer and more frequent as the climate changes.
So you should know the words forecasters use to describe these weather events — and the risks they pose.
Heat advisory: Advisories are issued when temperatures are expected to be hot enough to cause discomfort and potentially lead to heat-related illnesses, especially for more vulnerable populations like young children and the elderly.
Extreme heat watch: Watches are essentially forecasts for upcoming periods of extreme heat. Forecasters say heat watches often cover wide areas and will be revised into more focused warnings and advisories as conditions become clearer over time. Watches are a good time to prepare for extreme heat.
Extreme heat warning: Warnings are issued when heat levels are or will likely become extremely dangerous. Under extreme heat warnings, it's a good idea to avoid strenuous outdoor activity, stay hydrated and help loved ones and pets stay cool.
Forecasters are also warning of dangerous rip currents and swells along the coast this weekend.
If you’re headed to the beach to beat the heat, as many Southern Californians likely are, they recommend staying out of the water or, if you do go swimming, stay in front of lifeguards. It’s also a good idea to avoid jetties and tidal rocks.

This weekend will also come with a high risk of wildfires.
Forecasters warn that fire danger will be elevated through at least Monday, driven by heat, dry vegetation and low humidity levels away from the coast.
Despite some extra moisture in the air over the last several weeks, there hasn’t been enough to actually produce rain. Without precipitation, and under consistently high temperatures, plants will continue to dry out and become fuel.
“We have humidity, but it's not reaching the saturation point. Therefore, we won't have a cloud. We won't have precipitation,” said Rong Fu, an atmospheric scientist at UCLA who specializes in weather patterns and wildfires.
Fu said a system of high atmospheric pressure sitting over the Western U.S. is pushing warm, dry air across the Sierra Nevada from inland deserts and into Southern California.
That can generate what’s known as downslope wind. Those winds plus the already dry conditions align to create some especially dangerous fire weather.
One spark can easily turn into a large blaze, and humans are the most common cause of wildfires in Southern California, according to the U.S. Forest Service.
People can accidentally start wildfires in a range of ways, including throwing a lit cigarette into dry brush or dragging a chain behind a vehicle, creating sparks. One of the most common human causes is improperly extinguished camp fires.
Lightning can also start wildfires but is unlikely under current weather conditions. Southern California has seen minimal thunderstorms this summer.
The new normal?
Heatwaves in the summer and fall are obviously not new for Southern California, but they are getting worse.
Much of the heat currently blanketing the region is being driven by the high-pressure system, which traps warm air and compresses it against the ground, heating it even further. Forecasters say it’s likely to stay that way through the end of July.
But high-pressure systems like this one usually don’t stick around this long.
“For this pattern to linger almost two weeks — yeah, I would say, from a climatological point of view — that's pretty unusual,” Fu said.
One major driver of the change, Fu said, is climate change: As the climate warms, this kind of “anomalous” high pressure system will become stronger and more frequent.
And one consequence of hotter and longer heatwaves, is extended elevated periods of risky fire weather.

Topline:
The Los Angeles Homeless Services Authority Commission unanimously approved a $496 million budget for the 2026-27 fiscal year, moments before the agency released its annual homeless count.
Why it matters: The agency's new budget, approved today, is down 40% compared to $829 million approved last year. The drop accounts for L.A. County’s move away from the agency — along with fewer dollars from the state. The agency’s budget is now 73% funded by the city of L.A. At the same time, homelessness in L.A. is up. New numbers show the population of people living outdoors in the city grew by7.9% between early 2025 and 2026.
What does the money do: In addition to the annual tally,the Los Angeles Homeless Services Authority uses federal, state, county, and city dollars to provide a range of services — everything from safe places to park for people who live in their cars to permanent housing placement.
Who’s on the commission? LAHSA is governed by a 10-member commission that is half appointed by L.A. Mayor Karen Bass, and half appointed by each of the five county supervisors. Bass has served on the commission since appointing herself to it in fall 2023.
The backstory: The embattled agency, which has been at the forefront of the region’s response to homelessness for more than three decades, is currently fighting for survival. Following a series of harsh audits and a judge’s rebuke of LAHSA’s spending and management, L.A. County supervisors pulled funding from the agency. LAHSA is also in the middle of a court battle with the Trump administration, which is seeking to cut its access to hundreds of millions of dollars in federal funds.
