Since 1986 almost nothing has burned near Carnduff: 0% of the land within 25 km, or 0.000% a year. Seismic risk runs low: $0.008 of expected damage per $1,000 of buildings a year, the typical town $0.030. Carnduff grades B for hazard risk; wildfire is low here, so it earns no credit.

Carnduff grades B for hazard risk
Risk averages earthquakes and radon; wildfire joins only where it pulls the average down, so a town like Carnduff with little fire nearby would get no credit for it.
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.
Little of the land around Carnduff has burned: 0% within 5 km, 0% within 25 km since 1986
Fires mapped since 1986 around where Carnduff’s residents live, and the fuel next to their homes.
Low: the land around Carnduff burns at 0.000% a year, where the typical Canadian town sees 0.000%.
Land that isn’t forest covers nearly all the ground around Carnduff: forest fuel is 0% within 5 km and 0% within 25 km.

Nothing here counts toward Risk; the studies are pointers to the maps their owners keep for Carnduff.
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.”
Little shaking expected in Carnduff: $0.008 a year per $1,000
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
Carnduff’s $0.008 is a fraction of the typical town’s $0.030 (0.3 times as much): quiet ground by Canadian standards.
Shaking damage a year per $1,000 of building value
Earthquake risk in Saskatchewan peaks in Weyburn ($0.033); Carnduff, at $0.008, sits above the median of $0.006.

Get ready for what Carnduff faces
What to do about the hazards Carnduff 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.
- Clear needles and wood nearby.
- Keep a grab-and-go bag ready.
- In smoke, stay in; filter air.
- Has it had a radon test?
- Ask the municipality for flood maps.
- Are flood and wildfire insured?
What this data can and can’t tell you
- Flood studies aren’t flood zones. NRCan’s inventory says where flood mapping exists, not where water goes; the map’s owner is the authority for Carnduff.
- Wildfire counts one way. For Carnduff, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
- Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for Carnduff is its health region’s, the survey’s design unit.
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Carnduff’s census subdivision (a neighbourhood shows its city’s).
