Wildfire is a real hazard for Lake Country: 20% of the land within 25 km has burned since 1986, 0.51% a year, in the high band. Shaking is less of a worry than in most places, at $0.012 a year per $1,000 of building value ($0.030 typical). In Health Canada’s survey, 17% of homes tested in the area exceeded 200 Bq/m³ (6.6% typical). Lake Country grades D− for hazard risk, with wildfire counted against it.
What stands out about Lake Country’s hazards
Four national sources, each read for Lake Country: earthquakes, radon, past fires and flood studies.
What Lake Country faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Lake Country grades D− for hazard risk
Earthquake risk and radon make Lake Country’s grade; wildfire can only lower it, never raise it, and flood studies are listed but not scored.
Its place: #247 of 254 in British Columbia and #2,572 of 2,589 Canadian towns.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. Small fires and grass fires are largely missing from the national burned-area record.
Fire country: 20% of the land within 25 km of Lake Country has burned since 1986, 5% within 5 km
Fires mapped since 1986 around where Lake Country’s residents live, and the fuel next to their homes.
The yearly burn rate around Lake Country is 0.51%, against 0.000% for the typical Canadian town: the high band.
Forest fuel covers 39% of the land close to Lake Country and 49% across 25 km.

Burn rate a year, towns in British Columbia · highest of 255
The land around Lake Country burns at 0.51% a year, the 8th highest rate of 255 towns in British Columbia; Oliver tops it at 0.98%.
Each bar: the yearly average share of land within 25 km of a town’s homes that burned, 1986–2025 (CWFIS); the seven highest towns of 2,500 people or more.
Just 1.9% of Canada’s 2,610 towns burn fast enough for the high band where Lake Country sits; 0.2% burn faster.
Bands of the yearly burn rate: low under 0.05%, moderate under 0.25%, high under 1%, very high 1% or more; towns of 2,500 people or more.

Towns with a flood study on file
Lake Country is one of the 76% of towns in British Columbia with a flood study on file; across Canada it is 58%.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Flood is shown here, never graded: a study says where a map exists, not how many of Lake Country’s homes stand in a flood zone.
The inventory’s own caution (NRCan): “The Canada Flood Map (CFM) does not include every flood hazard map in Canada and may be incomplete or contain inaccuracies. It should not be relied upon as the official source of flood mapping information. Furthermore, if a map appears to be missing, this does not necessarily mean that the area has never been mapped. For the official version of a map, updated information, or confirmation of applicable regulations, please contact the local authority responsible for flood mapping.”

Earthquakes cost buildings in Lake Country just $0.012 per $1,000 a year
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
At $0.012 per $1,000, Lake Country carries 0.4 times the typical Canadian town’s earthquake risk ($0.030): low.
Shaking damage a year per $1,000 of building value
Below the middle in British Columbia: Lake Country’s $0.012 against a median of $0.36; Duncan has $1.33.
NRCan seismic risk model (2022): mean yearly building loss per $1,000 of value; medians of towns of 2,500 people or more.
84% of Canada’s 2,611 towns expect more shaking damage than Lake Country.
Each column: the share of Canada’s towns of 2,500 people or more in that range of yearly loss per $1,000 (NRCan, 2022).
The loss is to Lake Country’s buildings alone, from ground shaking; infrastructure and secondary hazards are left out.

Test for radon in Lake Country: 17% of area homes were over the guideline
Health Canada’s survey of long-term home tests: the share above the 200 Bq/m³ guideline. · Measured across the Okanagan health region: radon tests
Lake Country’s survey area reads 17% over the guideline, well past the typical Canadian town’s 6.6%.
Tested homes over 200 Bq/m³
Over 600 Bq/m³
More homes top the guideline around Lake Country (17%) than in the typical town in British Columbia (1.8%); 2.8% went over 600.

The 10–20% band holds 22% of Canada’s 2,611 towns, Lake Country among them; 4.6% rank above.
Each bar: the share of Canada’s towns of 2,500 people or more whose survey area had that share of tests over 200 Bq/m³.
A survey sample isn’t a map: any home in Lake Country can be high, and a three-month test is the only way to know.

Radon is the survey area’s figure, so neighbours in one area share it.
Get ready for what Lake Country faces
Practical steps for Lake Country’s hazards, most pressing first.
- Clear needles and wood nearby.
- Keep a grab-and-go bag ready.
- In smoke, stay in; filter air.
- Test for three months in winter.
- Over 200 Bq/m³: fix it.
- Kits are cheap; pros test too.
- Never drive through floodwater.
- Move papers and medicines upstairs.
- Ask whether your street is mapped.
- Has it had a radon test?
- Check the address on the flood map.
- How close is the forest edge?
- Are flood and wildfire insured?
What this data can and can’t tell you
- Wildfire counts one way. Wildfire is read from the national burned-area record around Lake Country’s homes since 1986, a history of fire that may lower Risk but never raises it.
- Flood studies aren’t flood zones. A study’s area can be a whole watershed or province, so being on the inventory says a map exists, not that a home in Lake Country floods.
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Lake Country’s figure is its subdivision’s.
- Radon is a survey. The radon share comes from about 14,000 long-term home tests in 2009–2011, pooled for now by the 2007 health region Lake Country sits in.
Questions about flooding and hazards in Lake Country
Is Lake Country at risk of wildfire?
It is: 20% of the land within 25 km of Lake Country has burned since 1986, the latest in 2025, which puts it in the high band that lowers Risk.
Is radon a problem in Lake Country?
17% of the 109 homes Health Canada tested around Lake Country topped the guideline; your own house needs its own test.
Does Lake Country flood?
Lake Country’s area has been studied for flooding, and the owner’s map shows which streets lie in a zone; the grade leaves flood out.
How is Lake Country’s Hazard risk Grade worked out?
Lake Country grades D− for hazard risk, from earthquakes and radon, with wildfire counted only where it lowers the grade.
How big is the earthquake risk in Lake Country?
About $0.012 a year per $1,000 of building value, NRCan’s long-run expectation for Lake Country.
