The verdict

Two federal records point in the busier direction for Roseau County. Its 26 FEMA declarations are 47% above the Minnesota county mean and exceed the count for 75% of the 3,266 counties in this registry. Separately, FEMA's National Risk Index places it safer than 44%, based on modeled expected annual loss, social vulnerability, and community resilience.

Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Roseau County is led by Riverine Flooding (about $10.2M Expected Annual Loss, Historical Loss Ratio Relatively High), while Wildfire carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

What does Roseau County's hazard record show?

Reading the federal records together

The NFIP claims register shows a middle-volume loss record here: 279 paid claims, totaling $3.4M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $12.2K average describes payments on recorded claims only, leaving uninsured damage and properties without a claim outside the measure.

The declaration register points in the busier direction. Roseau County's 26 federal records stand 47% above the Minnesota county mean of 17.7. That comparison describes how often federal action was recorded, including any Major Disaster, Emergency, and Fire Management entries shown on this page; it does not convert the count into future probability.

FEMA National Risk Index

FEMA's data shows an elevated National Risk Index composite of 43.9/100 for this county (Relatively Low rating). Expected Annual Loss comes in at Relatively Low (roughly $15.7M in annualized losses). Social vulnerability (Relatively Low) and community resilience (Relatively High) both factor into how that raw exposure plays out on the ground. Among the 18 modeled hazards, Wildfire carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at roughly once every 96 years here.

How often does each hazard strike Roseau 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.

Wildfire Relatively Moderate roughly once every 96 years
Drought Relatively Moderate 21 modeled event-days per year
Winter Weather Relatively Moderate an average of 19 times per year
Riverine Flooding Relatively Low roughly once every 1 years
Cold Wave Relatively Low an average of 21 times per year
Ice Storm Relatively Low roughly once every 3 years

What Flood declarations mean here

Flood is the most frequent declaration type on Roseau County's record, 62% 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: Wildfire

Wildfire risk in the model reflects fuel, terrain, weather and how much development sits in the wildland-urban interface. It is one of the few hazards where the exposure is materially changed by land management and building choices, not only by where the county happens to be.

Worth noting for Roseau County: the model and the federal record do NOT point at the same hazard. Wildfire 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.

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.
