In Canada, There Is a Salt Lake That Changes Color by Itself in Summer and Forms Colorful Spots. Meet the Mysterious Spotted Lake, a Sacred and Fascinating Place in British Columbia.
Imagine a lake that seems to come from another planet. In summer, it partially dries up and reveals hundreds of colorful puddles in shades of green, blue, yellow, and white, forming a mesmerizing natural mosaic. This place exists — and it is located inland in British Columbia, Canada. Known as Spotted Lake, it intrigues locals, fascinates tourists, and carries centuries of mystical stories.
But is it true that it bubbles up and “spits” out dead fish? Let’s explore the truth behind this modern legend, which went viral on social media, but mixes myth with science.
Where Is the Lake That Changes Color by Itself?
The Spotted Lake, whose traditional name is Kliluk, is located about 10 km northwest of the city of Osoyoos, in the Similkameen Valley, British Columbia — one of the hottest and driest regions in Canada. It is a transition area between the Canadian desert and the Rocky Mountains, and therefore it harbors unique ecosystems and improbable landscapes.

For most of the year, the Spotted Lake looks like an ordinary lake. But as summer progresses and the water evaporates, the visual phenomenon begins: hundreds of colorful circular spots appear in the shallow bed of the lake, as if nature had painted a surreal palette.
Why Does the Lake Change Color?
The answer lies in the highly mineralized chemical composition of the lake. It is salty, alkaline, and without a natural outlet — meaning that water is only lost through evaporation, which concentrates the salts present.
Among the main minerals accumulated are:
- Magnesium sulfate
- Sodium sulfate
- Calcium salts
When the water level decreases in summer, these compounds crystallize into circular shapes. The color of each spot depends on the concentration and type of salt, as well as the temperature and intensity of evaporation.
The result is a unique visual spectacle in the world, attracting photographers, scientists, and the curious from across the globe.
Does Spotted Lake Bubble and Spit Out Dead Fish?
Despite what some sensationalist headlines and viral videos suggest, there are no reliable records that Spotted Lake bubbles or “spits” out dead fish. This part of the story seems to be a modern exaggeration, possibly confused with real behaviors of other lakes in the region.
What is true:
- Some neighboring lakes, such as Osoyoos Lake or Somenos Lake, have recorded fish deaths in summer, usually caused by low oxygen levels, increased water temperature, or bacterial blooms.
- Spotted Lake is not a habitat for known fish due to its high salinity and alkalinity — inhospitable conditions for most aquatic species.
- It does not bubble naturally, although the spots may seem alive in the scorching sun due to the refraction of light over the salt crystals.
In summary: Spotted Lake does not spit fish, but it remains an extraordinary natural and visual phenomenon.
Spiritual and Cultural Significance
For the Syilx peoples, also known as the Okanagan Nation, the lake is called Kliluk and is considered sacred. For centuries, it has been used in healing rituals, spiritual ceremonies, and medicinal practices based on the mineral-rich waters.
Each spot was seen as a “medicinal pool,” with distinct properties according to color and predominant minerals. Even today, the site is revered as a space for spiritual connection with nature.
Brief History of Spotted Lake
In the early 20th century, the minerals of the lake attracted attention for more pragmatic reasons: they were extracted for industrial use. During the First World War, compounds from Spotted Lake were used in the manufacture of munitions. This caused environmental degradation and raised alarms about the preservation of the site.
Until the early 2000s, the lake was privately owned. In 2001, it was finally purchased by the Okanagan Nation Alliance, an indigenous consortium that fights for the preservation of the territory and traditional knowledge.
Since then, access to the lake has been restricted. A fence prevents visitors from walking up to the spots. However, there is a lookout by the roadside, where the phenomenon can be safely and respectfully observed.
When to Visit and What to Expect
The best time to witness the phenomenon is between August and September, during the peak of the Canadian summer. At this time, evaporation is at its maximum and the scenery is most intense.
Between October and June, the lake returns to looking ordinary: full of water and without colorful marks. Still, the mountainous scenery of the region makes the trip visually rewarding.

Spotted Lake, or Kliluk, is a perfect blend of science, ancestral culture, and natural beauty. What seems like magic is actually a high-impact visual chemical reaction, fueled by the dry climate and the mineral properties of the Canadian soil.
And although it neither bubbles nor spits fish, as some stories suggest, the lake does have the power to inspire, provoke curiosity, and touch those who observe it — whether in person or through images shared around the world.
