The verdict

Bayfield County has a nationally busy FEMA history: 12 declarations, more than 14% of counties in this registry. But the state comparison tempers that reading: the total is 3% below the Wisconsin county mean. FEMA's separate National Risk Index places the county safer than 35%; that score models loss and vulnerability rather than counting declarations.

What does Bayfield County's hazard record show?

FEMA National Risk Index

FEMA's data shows an elevated National Risk Index composite of 35.1/100 for this county (Very Low rating). Expected Annual Loss comes in at Very Low (roughly $9.3M in annualized losses). Social vulnerability (Relatively High) and community resilience (Relatively High) both factor into how that raw exposure plays out on the ground. Among the 18 modeled hazards, Cold Wave carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at an average of 9.5 times per year here, based on 133 historical events on record.

Reading the federal records together

This county has a small entry in FEMA's NFIP paid-claims table: 16 claims and $137.0K paid in total. PlainHazard calls 1-49 claims a light registry record, a label for this dataset rather than a finding that flood exposure is low. A short claims history can also reflect insurance take-up, the period covered, or losses that were never insured.

Start with the state benchmark: a Wisconsin county averages 12.3 federal declaration records, while Bayfield County has 12. The gap is 3% below that mean. Fewer entries indicate a quieter history of recorded federal actions, not immunity from a hazard and not a prediction about what happens next.

How often does each hazard strike Bayfield County?

FEMA's National Risk Index models a historical event count and an annualized frequency for each hazard type. Most hazards are expressed as modeled occurrences per year; FEMA expresses drought and heat-wave frequency as event-days per year. These modeled frequencies are not forecasts.

Hazard NRI Risk Rating Recurrence
Cold Wave Relatively Moderate an average of 9.5 times per year
Winter Weather Relatively Moderate an average of 30 times per year
Strong Wind Relatively Moderate roughly once every 1 years
Lightning Relatively Moderate an average of 27 times per year
Riverine Flooding Very Low roughly once every 2 years
Heat Wave Very Low 1.1 modeled event-days per year
Hail Very Low an average of 1.3 times per year
Landslide Very Low roughly once every 2 years
Coastal Flooding Very Low roughly once every 83 years
Drought Very Low 6 modeled event-days per year
Wildfire Very Low roughly once every 12,525 years
Tornado Very Low roughly once every 5 years
Ice Storm Very Low roughly once every 13 years
Earthquake No Rating roughly once every 11,364 years

What Flood declarations mean here

Flood is the most frequent declaration type on Bayfield County's record, 42% of its declarations. Federal flood declarations cover two mechanisms that behave very differently: riverine flooding, which builds over days as a watershed drains and is usually forecast well in advance, and flash flooding, which can arrive in under an hour from rainfall that fell somewhere upstream.

Flood is also the one hazard class where a second federal dataset exists for the same events. The National Flood Insurance Program records what was actually paid on insured losses, so it measures a narrower thing than the declaration count: uninsured damage, and flooding outside mapped special flood hazard areas, never enters it. Reading the two together is more informative than either alone.

Declaration counts describe past federal action. They are a record of what was declared, not a forecast of future hazard probability.

The model's sharpest exposure here: Cold Wave

Cold Wave measures exposure to extreme cold rather than to snow. Its harm is concentrated in health effects, burst infrastructure and energy demand spikes, and it falls hardest where the building stock and the grid were not built with sustained cold in mind.

Worth noting for Bayfield County: the model and the federal record do NOT point at the same hazard. Cold Wave carries the highest modeled rating (Relatively Moderate), while the county's declaration history is led by Flood. That is not a contradiction, the two measure genuinely different things. Declarations record federal ACTION, which requires damage costly enough to exceed state and local capacity; the Risk Index models EXPECTED annual loss across all 18 hazards whether or not any declaration ever followed. A hazard can be the county's largest modeled exposure and never once have driven a declaration.

National Risk Index ratings are modeled estimates of expected annual loss, not predictions of what will happen in any given year.

Data-matched county comparisons

Bayfield County's closest FEMA peer: Thomas County, KS

Comparisons use published FEMA declaration fields plus the National Risk Index composite for Bayfield County. Record similarity, not a safety rating.

How these peers are chosen

Cohort: Published U.S. county equivalents outside the source state or territory. Each metric keeps six ETL candidates; three unique destinations are shown after de-duplicating across axes. Declaration-volume ranking combines count and Major-disaster share and prefers a different leading incident type; Major-share ranks the Major fraction adjusted for volume; NRI ranks the modeled composite score only.
