Cartwright-Roblin grades B− for hazard risk
For Cartwright-Roblin, Risk will be the average of earthquakes and radon, with wildfire added only if it makes the average worse.
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.

The flood map inventory lists nothing for Cartwright-Roblin
What Canada’s Flood Map Inventory lists for Cartwright-Roblin: who studied flooding and where to see their maps.
The inventory has nothing for Cartwright-Roblin, but a local or conservation-authority map may still exist.
Towns with a flood study on file
No study touches Cartwright-Roblin; in Manitoba, 18% 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.
Flood is shown here, never graded: a study says where a map exists, not how many of Cartwright-Roblin’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.”

Get ready for what Cartwright-Roblin faces
Practical steps for Cartwright-Roblin’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
- 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 Cartwright-Roblin sits in.
- 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 Cartwright-Roblin floods.
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Cartwright-Roblin’s census subdivision (a neighbourhood shows its city’s).
- Wildfire counts one way. For Cartwright-Roblin, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
