The burned-area map is nearly blank around Langenburg, 0% within 25 km since 1986, 0.000% a year. Earthquakes matter little: NRCan’s model puts building losses at $0.007 a year per $1,000 of value, against $0.030 for the typical town. Langenburg grades B− for hazard risk; wildfire is low here, so it earns no credit.
What stands out about Langenburg’s hazards

Langenburg grades B− for hazard risk
Two inputs always count for Langenburg, earthquakes and radon; the third, wildfire, counts only against a town.
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.
Few fires near Langenburg: 0% within 5 km, 0% within 25 km
Past fire around Langenburg’s homes, from the national burned-area record, with the fuel within 5 km.

Around Langenburg the forest is thin or far off: 0% of the land within 5 km and 0% within 25 km is forest fuel.
Shares of land within 5 and 25 km of populated blocks: burned at least once in 1986–2025 (CWFIS burned-area composite), forest fuel and grass (fire behaviour fuel types, 2026, 250 m grid).
Burn rate a year, towns in Saskatchewan · highest of 105
Little or nothing burns around Langenburg in a typical year; 55 of the 105 towns in Saskatchewan share that, and La Loche leads at 1.94%.
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.
Only 7.5% of Canada’s 2,610 towns are above the low band, which holds 92%; Langenburg, at a rounded zero, is far from them.
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 Langenburg
What Canada’s Flood Map Inventory lists for Langenburg: who studied flooding and where to see their maps.
NRCan’s inventory is silent on Langenburg, so any flood map would be the municipality’s own.
Towns with a flood study on file
Mapping in Saskatchewan reaches 55% of towns, below the 58% across Canada, and not Langenburg.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
The grade leaves flood out, since a study area says nothing about how many of Langenburg’s homes are at risk.
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.”
Low seismic risk in Langenburg: $0.007 per $1,000 of buildings a year

Get ready for what Langenburg faces
What to do about the hazards Langenburg 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
- Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, Langenburg’s included.
- 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 Langenburg.
- Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for Langenburg is its health region’s, the survey’s design unit.
- 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 Langenburg.
