Fire is a regular visitor: 23% of the land within 25 km of Logan Lake has burned since 1986 (0.58% a year). For earthquakes Logan Lake is middling, $0.027 a year per $1,000 against $0.030 for the typical town. Radon is about average around Logan Lake: 6.4% of tested homes in the survey area topped the guideline, against 6.6% for the typical town. Logan Lake grades D− for hazard risk, with wildfire counted against it.
What stands out about Logan Lake’s hazards
Four national sources, each read for Logan Lake: earthquakes, radon, past fires and flood studies.

Each hazard against its own yardstick; meters run from low to high on that yardstick.

Hazard risk in Logan Lake: D−
The grade weighs Logan Lake’s seismic risk and radon equally, and wildfire is one-sided: a high band counts against a town, a low one earns nothing.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. Small fires and grass fires are largely missing from the national burned-area record.
Fire country: 23% of the land within 25 km of Logan Lake has burned since 1986, 43% within 5 km
Past fire around Logan Lake’s homes, from the national burned-area record, with the fuel within 5 km.
The yearly burn rate around Logan Lake is 0.58%, against 0.000% for the typical Canadian town: the high band.
The nearer ring around Logan Lake is less wooded (28% forest fuel) than the land out to 25 km (51%).

Burn rate a year, towns in British Columbia · highest of 256
The land around Logan Lake burns at 0.58% a year, the 5th highest rate of 256 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.
Logan Lake is one of the few of Canada’s 2,610 towns in the high band (1.9%); 0.2% rank very high.
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.

Fraser Basin Council has mapped flooding for Logan Lake (1 study)
What Canada’s Flood Map Inventory lists for Logan Lake: who studied flooding and where to see their maps.
One study on the inventory touches Logan Lake, Fraser Basin Council’s from 2020, and its area can be large, so it says a map exists, not that the town floods.
| Study | By | Year | Status |

| Thompson River Watershed Base Level Flood Hazard Mapping | Fraser Basin Council | 2020 | final |
Towns with a flood study on file
Its flood study puts Logan Lake with 76% of towns in British Columbia; Canada’s share 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 Logan Lake’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 Logan Lake $0.027 per $1,000 a year
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
Earthquake losses in Logan Lake, $0.027 per $1,000, are in line with the typical $0.030 (0.9 times).
Shaking damage a year per $1,000 of building value
At $0.027, Logan Lake is below the typical town in British Columbia ($0.36); Duncan is highest at $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.
Logan Lake’s earthquake risk lands near the centre of Canada’s range; 53% of the 2,611 towns are higher.
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 model counts damage to Logan Lake’s buildings and their occupants from shaking only: not liquefaction, landslides, tsunami or fires after a quake.

Some radon around Logan Lake: 6.4% of area homes over the guideline
Long-term radon tests in homes across the survey area, against Health Canada’s guideline.
The survey area of Logan Lake reads 6.4%, a shade from the typical Canadian town’s 6.6%. Logan Lake doesn’t get its own radon tests figures; the ones here come from the Thompson/Cariboo health region.
Tested homes over 200 Bq/m³
Over 600 Bq/m³
Logan Lake’s area, at 6.4%, is above the median in British Columbia (1.8%).
Health Canada radon survey (2009–2011), by 2007 health region; medians of towns of 2,500 people or more.
A middling share of high tests puts Logan Lake with 37% of Canada’s 2,611 towns, below 26% of them.
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.
Basements, soil and how a house is sealed decide its radon, so in Logan Lake only a test can say.

Get ready for what Logan Lake faces
What to do about the hazards Logan Lake faces, and what to ask before you buy.
- 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
- Flood studies aren’t flood zones. The flood inventory points to maps; it is incomplete and not the official source, so ask the municipality about any street in Logan Lake.
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Logan Lake takes its 2007 health region’s share.
- Earthquakes are modelled. Shaking damage is modelled from the ground, the buildings and the odds of each quake, and published for whole subdivisions such as Logan Lake’s.
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of Logan Lake’s homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
Questions about flooding and hazards in Logan Lake
Is radon a problem in Logan Lake?
Around Logan Lake, 109 survey homes were tested and 6.4% came in over 200 Bq/m³, a guide to the area, not to any one home.
How big is the earthquake risk in Logan Lake?
In NRCan’s seismic model, Logan Lake’s buildings lose $0.027 per $1,000 of value in an average year.
How is Logan Lake’s Hazard risk Grade worked out?
Logan Lake grades D− for hazard risk, from earthquakes and radon, with wildfire counted only where it lowers the grade.
Does Logan Lake flood?
The inventory lists a study touching Logan Lake; whether a given street floods is on that map, not in the grade.
Is Logan Lake at risk of wildfire?
More than most Canadian towns; Logan Lake’s high band rests on 23% of nearby land burned since 1986 (most recently 2023).
