The national fire record shows next to nothing around Moosomin, 0% of the land within 25 km since 1986 (0.000% a year). Shaking is less of a worry than in most places, at $0.006 a year per $1,000 of building value ($0.030 typical). Moosomin grades B− for hazard risk; wildfire is low here, so it earns no credit.

Moosomin grades B− for hazard risk
Seismic risk and radon set Moosomin’s grade, wildfire can drag it down, and flood mapping stays out of it.
Its place: #66 of 104 in Saskatchewan and #1,591 of 2,589 Canadian towns.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. The burned-area record misses fires under about 10 ha and most grass and farm fires.
Little of the land around Moosomin has burned: 0% within 5 km, 0% within 25 km since 1986
Past fire around Moosomin’s homes, from the national burned-area record, with the fuel within 5 km.
In a typical year 0.000% of the land near Moosomin burns; the typical Canadian town sees 0.000%, and both are low.
Little near Moosomin’s homes can carry a forest fire; only 0% of the land within 5 km is forest fuel, and 0% within 25 km.
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 104
To three decimals the burn rate around Moosomin is zero, as for 54 of the 104 towns in Saskatchewan, while La Loche reaches 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.
Moosomin shares the low band with 92% of Canada’s 2,610 towns, its burn rate rounding to nothing; 7.5% 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.

The flood map inventory lists nothing for Moosomin
What Canada’s Flood Map Inventory lists for Moosomin: who studied flooding and where to see their maps.
NRCan’s inventory is silent on Moosomin, so any flood map would be the municipality’s own.
Towns with a flood study on file
No study touches Moosomin; in Saskatchewan, 55% of towns have one, below Canada’s 58%.
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 Moosomin’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.”
Little shaking expected in Moosomin: $0.006 a year per $1,000
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
Shaking costs the typical town $0.030 a year; in Moosomin it is only $0.006, 0.2 times as much.
Shaking damage a year per $1,000 of building value
The median in Saskatchewan is $0.006; Moosomin, at $0.006, is right beside it, and Weyburn tops the list at $0.033.

Test for radon in Moosomin: 25% of area homes were over the guideline
Long-term radon tests in homes across the survey area, against Health Canada’s guideline.
A higher share than most: 25% of tested homes around Moosomin, the typical Canadian town 6.6%. Moosomin doesn’t get its own radon tests figures; the ones here come from the Regina Qu'Appelle RHA.
Tested homes over 200 Bq/m³
Over 600 Bq/m³
More homes top the guideline around Moosomin (25%) than in the typical town in Saskatchewan (9.1%); 4.3% went over 600.

One home in five or more tests over the guideline around Moosomin; 3.1% of Canada’s 2,611 towns are in that band and 1.5% higher.
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.
Radon varies from house to house in Moosomin, so the survey is a reason to test, not a result for yours.

Get ready for what Moosomin faces
Practical steps for Moosomin’s hazards, most pressing first.
- 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. 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 Moosomin floods.
- 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 Moosomin sits in.
- Wildfire counts one way. For Moosomin, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Moosomin’s census subdivision (a neighbourhood shows its city’s).
Questions about flooding and hazards in Moosomin
Is Moosomin at risk of wildfire?
The burned-area record shows next to nothing around Moosomin (0% within 25 km since 1986), so its band is low.
