Wildfire is rare near Gold River: 1% of the land within 25 km has burned since 1986, a burn rate of 0.03% a year. Radon is lower than usual: 0.9% of tested homes in the survey area topped the guideline, against 6.6% for the typical town. Gold River grades B− for hazard risk, with wildfire counted against it.

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

Gold River grades B− for hazard risk
The grade weighs Gold River’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. The burned-area record misses fires under about 10 ha and most grass and farm fires.

Around Gold River fire takes 0.03% of the land in a typical year, the typical Canadian town 0.000%, which is low.
Forest fuel is denser close to Gold River (89% within 5 km) than further out (78% within 25 km).

In the upper half in British Columbia but far from Oliver (0.98%): Gold River ranks 83rd of 256, at 0.03% a year.
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.
The low band takes in 92% of Canada’s 2,610 towns, Gold River among them, though its rate is above zero; 7.5% rank higher.
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.

No flood study is listed for Gold River
What Canada’s Flood Map Inventory lists for Gold River: who studied flooding and where to see their maps.
An empty entry for Gold River on the inventory isn’t proof of safety; ask locally for flood maps.
Towns with a flood study on file
Mapping in British Columbia reaches 76% of towns, beside 58% across Canada, but not Gold River.
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 Gold River’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.”
Shaking is Gold River’s costliest hazard: $0.46 a year per $1,000
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
The typical town loses $0.030 a year to shaking; Gold River loses $0.46, 15.5 times as much.

Get ready for what Gold River faces
What to do about the hazards Gold River faces, and what to ask before you buy.
- 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.
- Drop, cover and hold on.
- Strap the water heater down.
- Keep 72 hours of supplies.
- Has it had a radon test?
- Ask the municipality for flood maps.
- Are flood and wildfire insured?
- Is earthquake cover included?
What this data can and can’t tell you
- Wildfire counts one way. Burned land within 25 km of where people live, averaged over 1986–2025 and checked for fuel near homes, is the measure; it looks back, not ahead, and only ever counts against Gold River.
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Gold River takes its 2007 health region’s share.
- Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, Gold River’s included.
- 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 Gold River.
