Hot dry hills smelling of sage, a gravel pull-off by the highway, and a wire fence. Beyond it a lake had come apart into spots, green and blue and yellowish, each with a pale crust round it like a saucer’s edge. A sign said whose it was and asked us to stay on this side. I stayed, a good while, hands resting on the top wire.
The short answer
Spotted Lake is a small saline, alkaline lake with no outlet, north-west of Osoyoos in the south Okanagan and eastern Similkameen country of British Columbia, beside Highway 3, Wikipedia records. In the Nsyilxcən language of the Syilx Okanagan Nation it is kɬlil̕xʷ, the spelling the Okanagan Nation Alliance uses (as indexed). Its water is rich in dissolved minerals, above all magnesium sulphate, with calcium and sodium sulphates and smaller amounts of others; as the water evaporates over the summer, the lake separates into many pools whose colours depend on their minerals and on the year’s rain. It has been a sacred medicine lake of the Syilx people for centuries. Since 2001 the land around it has been held for the Okanagan Nation, and the lake is fenced: visitors see it from a pull-off on the highway.
Why it's worth knowing
Why it is spotted. Magnesium sulphate, the mineral of Epsom salts, which crystallises as the summer heat drives off the water, is the main source of the colour, Wikipedia records, and as the lake shrinks, the hardened minerals form natural walkways between the pools. The American geologist Olaf P. Jenkins described the lake, with similar ones across the border in Washington, in a 1918 paper in the American Journal of Science titled “Spotted lakes of epsomite in Washington and British Columbia”. The pools change size and colour through the season.
A medicine lake. The Okanagan Nation Alliance describes kɬlil̕xʷ as a sacred medicine lake and protected cultural heritage site of the Syilx Okanagan people, where people from many nations came for the medicine it holds; ceremonial cairns stand around it, its page says (as indexed). Syilx people have gone there for healing, of body and spirit, for centuries, by the Alliance’s account and the Indigenous news service IndigiNews’ reporting (as indexed). The Alliance has opened its annual general assembly with a ceremony at the lake; IndigiNews headlined its report of one such gathering with a participant’s words: “This was like our hospital, this was like our church.”
Bought back. During the First World War, the lake’s minerals were dug and used in making munitions, Wikipedia records. The land later passed to the family of Ernest Smith, who held it for about forty years and in 1979 tried to raise interest in building a spa there. The Okanagan nations answered with an effort to buy it, and in October 2001 they reached a deal: 22 hectares (54 acres) for $720,000, of which the First Nations paid about a fifth and the federal Indian Affairs department the rest, by Wikipedia’s account. The Alliance’s own page gives the site as 56 acres, acquired in 2001 by the Chiefs of the Okanagan Nation Alliance with the federal minister of Indian Affairs and Northern Development, for the use and benefit of the Okanagan Nation (as indexed).
The field notes
The view from the fence
A roadside sign tells visitors that the lake is a culturally and ecologically sensitive area and a traditional medicine lake of the Syilx Okanagan people, and the fence keeps the public off it, Wikipedia records. The Okanagan Nation Alliance monitors access to the lake itself (as indexed). For a visitor, the lake is a view: from the highway pull-off, across the fence, down onto the pools. Destination Osoyoos, the town’s tourism body, describes it the same way: no one is permitted beyond the viewpoint, out of respect for the lake and for the Nation (as indexed).
A lake that can run low
The spots depend on the balance between the water that comes in and the summer heat that takes it away. The Okanagan Nation Alliance has described the lake as being affected by climate change, with a noticeable decline in its water level, IndigiNews reported (as indexed). The colours in any one summer depend on how much rain and snowmelt the lake received.

- Pull in, turn off the motor, and look from the roadside. That is the visit, and it is plenty.
- Read the sign by the fence to its last line, then look at the lake again.
- Visit in the hot months, early, before the glare flattens everything.
- Leave the drone in its box. Some places are not for looking down on.
- Buy peaches from a stall down the valley afterwards. (Juice dripped onto the page. It has never looked so cheerful.)
One of the spots. In high summer, Spotted Lake breaks into many separate pools, each ringed by a pale crust of crystallised salts, above all magnesium sulphate, and each a different shade of green, blue or yellow according to what is dissolved in it and how much water is left. The pattern shifts week by week as the water goes. The spots are part of a sacred medicine lake of the Syilx Okanagan Nation, and they are seen from the roadside fence; no one takes one home.
Tally, in the marginOne small green pool inside its crust of white, keeping entirely to itself. I liked it at once. It asked nothing of me but that I stay on my side of the wire, which seemed very little to give in return for a colour like that.
Getting there
How to get there. By road. Spotted Lake lies beside Highway 3, about 10 km west of Osoyoos towards Keremeos, with a small roadside pull-off and room for only a few cars (Destination Osoyoos and travel guides, as indexed). Osoyoos is in the far south of British Columbia’s Okanagan Valley, just north of the border with Washington State. The lake is seen from the pull-off; there is no path to it and no admission.
When to go. Late June to early September, when the summer heat has separated the lake into its pools; earlier in the year it is usually one sheet of water. Travel guides recommend the morning light (as indexed). Summers in the south Okanagan are hot and dry.
What to arrange ahead. Nothing beyond the drive: there is no ticket and no tour. Bring water, and plan to stop only briefly, since the pull-off is small and on a highway.
Safety. The State Department has Canada at Level 1, exercise normal precautions, its lowest level; it notes petty crime in popular tourist places (advisory dated 5 June 2026 in its feed, read 7 October 2026). The hazards here are traffic on the highway at the pull-off and summer heat. Stay on the roadside side of the fence.

Common questions
Where is Spotted Lake?
Spotted Lake is beside Highway 3 about 10 km west of Osoyoos, in the south Okanagan of British Columbia, Canada, close to the border with Washington State. It is a small saline lake with no outlet, viewed from a roadside pull-off.
Why does Spotted Lake have spots?
Spotted Lake is rich in dissolved minerals, above all magnesium sulphate, with calcium and sodium sulphates. As summer heat evaporates its water, it separates into many pools whose colours depend on their minerals and the year’s rainfall, with hardened mineral rims between them.
Can you walk on Spotted Lake?
No. Spotted Lake is a sacred medicine lake of the Syilx Okanagan Nation, on land held for the Okanagan Nation since 2001. It is fenced, a roadside sign marks it as culturally and ecologically sensitive, and visitors view it from the Highway 3 pull-off.
Who owns Spotted Lake?
Spotted Lake’s land has been held for the use and benefit of the Okanagan Nation since 2001, when the Okanagan Nation Alliance and the federal Indian Affairs department completed its purchase from the Smith family. Wikipedia gives the price as $720,000 for 22 hectares, with the First Nations paying about a fifth.
What is the Syilx name for Spotted Lake?
In the Nsyilxcən language of the Syilx Okanagan Nation, Spotted Lake is kɬlil̕xʷ, as the Okanagan Nation Alliance spells it; Wikipedia gives the form Kłlil’xᵀ, and older English sources write Kliluk or Khiluk. The lake has been a place of healing for Syilx people for centuries.
When is the best time to see Spotted Lake?
The pools of Spotted Lake are clearest from late June to early September, after the summer heat has evaporated much of the water and separated it into coloured spots. Earlier in the year, after snowmelt and rain, the lake is usually a single sheet of water.
What minerals are in Spotted Lake?
Spotted Lake holds dense deposits of magnesium sulphate (epsomite), with calcium and sodium sulphates and smaller amounts of other minerals, including silver and titanium, Wikipedia records. A 1918 paper by Olaf P. Jenkins in the American Journal of Science described it as a spotted lake of epsomite.
What happened to Spotted Lake in the First World War?
During the First World War, minerals were taken from Spotted Lake in British Columbia and used in the manufacture of munitions, Wikipedia records. The lake has since been fenced and returned to the Okanagan Nation, whose people regard it as a sacred medicine lake.
