Interesting facts

  • During the First World War, labourers are said to have skimmed up to a ton of salts a day from the lake for munitions factories in eastern Canada.
  • Besides magnesium, calcium and sodium sulfates, the water holds high levels of eight other minerals and small traces of silver and titanium.
  • At the height of a dry summer the lake can split into several hundred separate spots, each with its own mineral mix and colour.
  • The lake has no outflow at all, so it loses water only by evaporation, which is what concentrates its salts so strongly.
  • A 1918 paper in the American Journal of Science described the lake among the spotted lakes of epsomite, the mineral form of magnesium sulfate.
  • In 1979 the owner sought to build a spa at the lake, and opposition from Okanagan elders started the long campaign to buy it back.
  • The 2001 purchase of the land around the lake cost about 720,000 Canadian dollars, with the Okanagan Nation contributing around a fifth.
  • The lake itself is small, covering only about 15 hectares in a basin between dry, rocky hills.

Why it is worth it

Spotted Lake is a small alkaline lake in a dry valley of southern British Columbia, and in high summer it looks like nothing else on the continent. As the water evaporates in the heat, its heavy load of dissolved minerals, above all magnesium sulfate, with calcium and sodium sulfates and traces of other elements, crystallises out, and the lake breaks up into hundreds of separate pools, each ringed by pale mineral walkways. Their colours vary with the chemistry and the season, from blue through green to yellow, so that from above the basin resembles a spotted palette laid out between the hills.

For the Syilx Okanagan people the lake is kล‚lilx'w, often written Kliluk, a sacred place of healing whose waters and muds have been used for centuries, each circle believed to hold its own healing properties. The lake passed into private hands in the colonial era; during the First World War its salts were dug out and shipped for use in ammunition manufacture, and for around forty years afterwards the land was owned by a local family. In 2001 the Okanagan Nation bought back 22 hectares around the lake, with most of the cost paid by the federal government, and it remains a protected cultural site under Syilx care.

The lake is meant to be seen, not entered. A roadside viewpoint on Highway 3 looks down across the spots from beside a fence, and a sign asks visitors to respect the site; the spots are at their clearest in the heat of summer, when evaporation is strongest, and change size and shape as the season goes on. For a closer understanding of its meaning, guided visits are occasionally led by Syilx guides.

Getting there

Spotted Lake lies in the Similkameen country beside Highway 3, the Crowsnest Highway, about 10 km west of Osoyoos; Penticton is about 45 km away. The nearest airport is Penticton Airport (YYF), about 43 km away. The lake is viewed from the fenced roadside pull-out on the highway.
