Read from FEMA’s records below. The page puts what stands out first.
Does Natrona flood? No paid flood claims on record
FEMA’s records show no paid flood insurance claims in Natrona. That’s not a promise: most homes don’t carry flood insurance, so small floods go unrecorded.
Natrona isn’t in FEMA’s Community Rating System, which cuts flood insurance up to 45% in towns that do extra flood-proofing.

- Check on older neighbors when the power goes out.
- Trim dead limbs over the house and driveway.
- Tie down trash cans and outdoor furniture.
- Stay clear of downed lines and call the utility.
- Look up the address on FEMA’s flood map.

What these numbers can and can’t tell you
- An average, not a forecast. FEMA’s National Risk Index estimates the damage 18 kinds of natural hazards cause in a typical year, from decades of records and models. A quiet decade can follow a bad year.
- Compared by rate. “Higher than N%” compares yearly damage as a share of what’s there, so a big city isn’t rated riskier just for having more buildings.
- Money that reached town. Flood claims are matched to Natrona’s own flood-insurance community; household aid to the registrant’s city; repair grants to Natrona.
- It follows property value. FEMA’s model weighs damage to buildings, so a place that recently lost many homes can rate lower than it feels.
