Why Can't You Swim in the Salton Sea: And Why Do Fish Wear Sunglasses?

The Salton Sea, a vast, shimmering body of water nestled in the California desert, has long been a subject of fascination and confusion. Once a bustling tourist destination, it now stands as a cautionary tale of environmental mismanagement and ecological collapse. But beyond its troubled history, the Salton Sea raises a peculiar question: Why can’t you swim in it? And while we’re at it, why do fish wear sunglasses? Let’s dive into the murky waters of this enigmatic lake and explore the many reasons why swimming in the Salton Sea is not just unadvisable, but downright bizarre.

1. The Salton Sea: A Brief History of Accidental Creation

The Salton Sea wasn’t always there. In fact, it’s a relatively recent addition to the California landscape, born out of a colossal engineering mistake in 1905. The Colorado River, swollen with floodwaters, breached an irrigation canal and poured into the Salton Sink, a below-sea-level basin. For two years, the river flowed unchecked, creating a massive inland sea. At its peak, the Salton Sea became a thriving resort destination, attracting celebrities and tourists alike. But the party didn’t last.

2. The Toxic Brew: What’s in the Water?

The primary reason you can’t swim in the Salton Sea is its water quality—or lack thereof. Over the decades, the lake has become a toxic soup of agricultural runoff, industrial waste, and decaying organic matter. Here’s what’s lurking beneath the surface:

• High Salinity: The Salton Sea is saltier than the Pacific Ocean, with salinity levels reaching up to 56 parts per thousand (compared to the ocean’s 35). This makes it inhospitable for most aquatic life and unpleasant for swimmers.
• Algae Blooms: The nutrient-rich runoff fuels massive algae blooms, which deplete oxygen levels in the water and create dead zones. When the algae die, they release hydrogen sulfide, a gas that smells like rotten eggs and can be harmful to humans.
• Heavy Metals and Pesticides: Decades of agricultural and industrial activity have left the lake contaminated with heavy metals like selenium and pesticides like DDT. These toxins accumulate in the water and sediment, posing serious health risks to anyone who comes into contact with them.

3. The Fishy Situation: Why Do Fish Wear Sunglasses?

Now, let’s address the elephant—or rather, the fish—in the room. Why do fish wear sunglasses? The answer lies in the Salton Sea’s unique ecosystem. As the lake’s salinity increased, native fish species died off, leaving behind a handful of hardy survivors like tilapia. These fish have adapted to the harsh conditions, but even they struggle to thrive. Some scientists joke that if fish could wear sunglasses, they’d need them to protect their eyes from the sun’s glare reflecting off the lake’s highly saline surface. In reality, the “sunglasses” are a metaphor for the fish’s resilience in the face of adversity.

4. The Smell: A Nose-Wrinkling Experience

If the toxic water isn’t enough to deter you, the smell certainly will. The Salton Sea is infamous for its pungent odor, a result of the decaying algae and fish that litter its shores. On hot, windy days, the stench can carry for miles, earning the lake the nickname “the rotten egg sea.” Swimming in such conditions would be like taking a dip in a giant, smelly petri dish.

5. The Shrinking Shoreline: A Lake in Decline

The Salton Sea is shrinking, and its receding waters are exposing vast stretches of dry, dusty lakebed. This “playa” is laden with toxic chemicals and fine particulate matter, which can become airborne and pose respiratory risks to nearby communities. Swimming in the lake would not only expose you to the water’s hazards but also to the dust storms that frequently sweep across the region.

6. The Wildlife Paradox: A Haven and a Death Trap

Despite its toxicity, the Salton Sea is a critical habitat for migratory birds, including endangered species like the brown pelican. The lake provides a vital stopover point along the Pacific Flyway, offering food and shelter to millions of birds each year. However, the same conditions that make the lake a haven for birds also make it a death trap. Birds that consume contaminated fish or water often suffer from disease and reproductive failure. Swimming in the Salton Sea would mean sharing the water with these struggling creatures, adding another layer of ethical complexity to the question.

7. The Human Impact: A Community in Crisis

The Salton Sea’s decline has had devastating effects on the surrounding communities. Once-thriving towns like Bombay Beach have become ghost towns, their economies decimated by the lake’s deterioration. The health impacts of the lake’s toxins and dust are also a growing concern, with residents reporting high rates of asthma and other respiratory illnesses. Swimming in the Salton Sea would not only endanger your health but also contribute to the ongoing exploitation of a fragile ecosystem.

8. The Future of the Salton Sea: Can It Be Saved?

Efforts to restore the Salton Sea have been ongoing for decades, but progress has been slow. Proposed solutions include importing seawater from the Gulf of California, constructing wetlands to filter runoff, and covering exposed lakebed to prevent dust storms. However, these projects require significant funding and political will, both of which have been in short supply. Until the lake is restored, swimming in the Salton Sea will remain a distant dream—or perhaps a nightmare.

9. The Philosophical Angle: Why Do We Want to Swim in the Salton Sea?

Perhaps the most intriguing question is why anyone would want to swim in the Salton Sea in the first place. Is it a desire to connect with nature, even in its most degraded form? Or is it a morbid curiosity, a fascination with the grotesque and the forbidden? Whatever the reason, the Salton Sea serves as a powerful reminder of humanity’s impact on the environment and the consequences of our actions.

10. The Final Verdict: Just Don’t Do It

In conclusion, the Salton Sea is a fascinating but deeply troubled body of water. Its toxic waters, foul odor, and shrinking shoreline make it an unsuitable—and unsafe—place for swimming. As for the fish wearing sunglasses, it’s a whimsical reminder of the lake’s unique challenges and the resilience of life in even the harshest conditions. So, the next time you’re tempted to take a dip in the Salton Sea, remember: some things are better left unexplored.
