You’ve probably seen the photos. The ones with the bleached tilapia bones crunching underfoot like snow and the abandoned trailers rotting in the desert sun. It looks like a post-apocalyptic movie set, but it’s actually just a few hours from Los Angeles. The Salton Sea before and after its transformation is a story that sounds like a fever dream. One minute it’s the "California Riviera" with more visitors than Yosemite, and the next, it’s a toxic dust bowl that smells like rotten eggs and despair.
It’s weird.
The sea shouldn't even be there. Most people think it’s a natural lake, but it was actually a massive engineering screw-up in 1905. The Colorado River jumped its banks during a canal project and flooded the Salton Sink for two years. By the time they plugged the hole, a 15-by-35-mile inland sea had formed.
The Glory Days: When the Salton Sea Was Actually Cool
Before the rot set in, the Salton Sea was the place to be. We’re talking the 1950s and 60s. It was the height of mid-century optimism. Developers saw a giant body of water in the middle of the desert and thought, "Hey, let’s build a resort."
And they did.
North Shore and Bombay Beach became legitimate tourist magnets. Frank Sinatra, Dean Martin, and Jerry Lewis used to hang out there. People were water skiing. They were speedboating. The Desert Shores Yacht Club was a real thing, not just a punchline. There were hotels, neon signs, and thousands of people flocking to the shore every weekend. At one point, the Salton Sea was actually out-drawing Yosemite National Park in terms of annual visitors.
Honestly, looking at old postcards of the Salton Sea before and after the decline is jarring. You see people in high-waisted swimsuits lounging on sandy beaches that are now made entirely of pulverized fish scales. Back then, the water was clear enough to swim in without worrying about developing a third eye.
But there was a ticking time bomb.
Since the sea has no outlet, any water that goes in stays there until it evaporates. When the water evaporates, it leaves behind salt. Lots of it. Because the sea is mainly fed by agricultural runoff from the Imperial Valley, it also collects every bit of pesticide, fertilizer, and salt used on the surrounding farms.
The Slow Motion Train Wreck
By the 1970s, the party started to end. Tropical storms in 1976 and 1977 caused massive flooding that destroyed a lot of the shoreline infrastructure. Many business owners just walked away. They didn't even pack. You can still find trailers today with 1970s calendars on the walls and dishes still in the cupboards.
Then the salinity spiked.

The water became saltier than the Pacific Ocean. Most of the fish species that had been introduced—like corvina and sargo—started dying off in massive numbers. Eventually, only the hardy tilapia could survive, and even they started having massive "die-offs." We’re talking millions of fish floating to the surface at once because of oxygen depletion caused by algae blooms.
The smell is something you never forget.
When those fish rot in 110-degree desert heat, the odor wafts across the Coachella Valley. It’s a mix of sulfur, dead organics, and salt. It’s heavy. It’s thick. It’s the smell of a dying ecosystem.
Why the Salton Sea Before and After Comparison Matters for Your Health
This isn't just an aesthetic tragedy or a sad story about a failed resort. It’s a public health crisis. As the sea shrinks—partly due to the 2003 Quantification Settlement Agreement (QSA) which diverted water away from the sea to San Diego—the shoreline recedes.
This exposes the "playa."
The playa is a fine, toxic silt sitting on the lakebed. It contains decades of accumulated arsenic, selenium, and DDT from farm runoff. When the Santa Ana winds kick up, they blow this toxic dust straight into the lungs of people living in the Imperial Valley.
According to data from the California Department of Public Health, children in the Imperial Valley have some of the highest rates of asthma-related ER visits in the state. It’s roughly double the California average. You’ve got a situation where the Salton Sea before and after its heyday has gone from a playground to a literal source of chronic illness.
Is Anything Actually Being Done?
For decades, the plan was basically "wait and see." There have been dozens of proposals. Some people wanted to build a pipeline to the Sea of Cortez. Others wanted to pump water in from the Pacific. Most of these plans were dismissed because they cost billions of dollars and the engineering was a nightmare.
Right now, the state is finally moving on the Salton Sea Management Program (SSMP).

They aren't trying to restore the whole sea anymore. That ship has sailed. Instead, they are building "species conservation habitats"—basically managed wetlands on the southern end of the sea. These are designed to provide habitat for migratory birds (since the Salton Sea is a crucial stop on the Pacific Flyway) and to keep the dust down by covering the exposed playa with water or vegetation.
- The Species Conservation Habitat (SCH) Project: This is a 4,000-acre project that creates ponds to support fish and birds.
- The Lithium Valley Hope: There is a massive deposit of lithium underneath the sea. Companies like Berkshire Hathaway Energy are looking at "direct lithium extraction" from the geothermal brine.
- Dust Suppression: Using "surface roughening" and planting salt-tolerant vegetation to stop the toxic dust from taking flight.
The lithium thing is the real wildcard. Some locals hope it will be the "White Gold" that finally brings money back to the region. If they can extract lithium for electric vehicle batteries while also funding the restoration, it could be a game-changer. But we’ve heard big promises before.
The Reality of Visiting Today
If you go there now, don’t expect a beach day. Bombay Beach has transformed into a weird, gritty art colony. It’s fascinating and beautiful in a "ruins of civilization" kind of way. Artists have built installations out of rusted metal and old TVs. It’s become a hotspot for photographers and filmmakers.
But you have to be careful.
The "sand" at the water's edge is mostly barnacles and fish bones. It’s sharp. The water is pea-green. You’ll see thousands of dead tilapia lining the shore. It’s a stark reminder of the Salton Sea before and after its peak—a skeleton of what was once a thriving oasis.
The birdwatching is still incredible, though. Even in its degraded state, the sea hosts hundreds of species, including American White Pelicans and Eared Grebes. It’s a weird paradox: a place that is simultaneously a biological wasteland and a vital sanctuary.
Misconceptions About the Sea
One big myth is that the sea is "dead." It’s actually too alive. The nutrient-rich runoff causes massive algae blooms. The algae dies, sinks, and bacteria eat it, using up all the oxygen in the process. The fish don't die from poison; they literally suffocate.
Another misconception is that the sea is a natural part of the landscape. While a larger "Lake Cahuilla" existed here thousands of years ago, the current sea is an accidental human creation. We created it, we used it, we broke it, and now we’re trying to figure out how to live with the consequences.
Actionable Steps for the Future
If you care about the region or are planning a visit to see this landscape for yourself, keep these points in mind:
- Check Air Quality Before You Go: Use sites like AirNow. If the wind is blowing and the PM10 levels are high, stay away. The dust is no joke and can cause immediate respiratory irritation.
- Support Local Advocacy: Organizations like the Salton Sea Action Committee and Alianza Coachella Valley work on the ground to push for dust suppression and health resources for local families.
- Respect the Residents: People still live in Salton City, Niland, and Bombay Beach. Don't treat their towns like a zoo. Be mindful of where you park and photograph.
- Educate on the Lithium Project: Keep an eye on the "Lithium Valley" developments. This is likely the only way significant funding will ever reach the sea for long-term stabilization.
- Visit with the Right Gear: If you're exploring the shoreline, wear thick-soled boots. The barnacle shells will rip through flip-flops or thin sneakers in minutes.
The Salton Sea before and after its collapse is a cautionary tale about water management in the West. It’s a beautiful, terrifying, and deeply complicated place that isn't going away anytime soon—even if the water does.
Key Takeaway: The Salton Sea is a human-made disaster that transitioned from a 1950s vacation paradise to a modern environmental and health crisis. Current efforts focus on dust suppression and habitat creation rather than a full "restoration" to its mid-century glory. Watching the progress of the Lithium Valley project is currently the most significant factor in determining the sea's future.
