The verdict
Stanley County has a nationally busy FEMA history: 14 declarations, more than 20% of counties in this registry. But the state comparison tempers that reading: the total is 26% below the South Dakota county mean. FEMA's separate National Risk Index places the county safer than 5%; that score models loss and vulnerability rather than counting declarations.

Stanley County's FEMA Risk Index score
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Stanley County is led by Riverine Flooding (about $3.4M Expected Annual Loss, Historical Loss Ratio Relatively Moderate), while Wildfire carries the highest National Risk Index rating (Very Low). EAL and risk score use different inputs; they need not agree.

What does Stanley County's hazard record show?
Reading the federal records together
The NFIP claims register shows a middle-volume loss record here: 117 paid claims, totaling $2.6M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $21.8K average describes payments on recorded claims only, leaving uninsured damage and properties without a claim outside the measure.
Start with the state benchmark: a South Dakota county averages 19.0 federal declaration records, while Stanley County has 14. The gap is 26% 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.
FEMA National Risk Index
FEMA's National Risk Index places this county in the low end of the national distribution, composite score 5.1/100 (Very Low). Expected Annual Loss is rated Very Low (roughly $4.3M in annualized losses). Two modifiers shape how that exposure becomes real-world harm here: social vulnerability (Very Low) and community resilience (Relatively Moderate). Even the county's top-rated hazard, Wildfire, only reaches Very Low on FEMA's scale, none of the 18 modeled hazards stand out here. FEMA's modeled frequency puts that hazard at roughly once every 1,105 years here.

How often does each hazard strike Stanley 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 |
|---|---|---|
| Wildfire | Very Low | roughly once every 1,105 years |
| Winter Weather | Relatively Low | an average of 16 times per year |
| Ice Storm | Relatively Low | roughly once every 2 years |
| Drought | Very Low | 43 modeled event-days per year |
| Landslide | Very Low | roughly once every 1 years |
| Riverine Flooding | Very Low | roughly once every 1 years |
| Cold Wave | Very Low | an average of 6.1 times per year |
| Heat Wave | Very Low | 3.8 modeled event-days per year |
| Tornado | Very Low | roughly once every 3 years |
| Hail | Very Low | an average of 2.9 times per year |
| Strong Wind | Very Low | an average of 2.7 times per year |
| Earthquake | Very Low | roughly once every 2,833 years |
| Lightning | Very Low | an average of 34 times per year |

What Severe Storm declarations mean here
Severe Storm is the most frequent declaration type on Stanley County's record, 36% of its declarations. In FEMA's vocabulary this covers convective weather: thunderstorm straight-line winds, large hail, and the multi-day outbreaks that often carry embedded tornadoes. Activity is heaviest in spring and summer, though the season varies by region.
These events behave differently from a hurricane on paper. Damage tends to be distributed along a storm track rather than concentrated on a coastline, and a declaration typically follows an outbreak that crossed several counties over a few days, not a single point of impact. Because the qualifying threshold is the cost of uninsured public and individual losses rather than storm intensity, two similar storms can produce a declaration in one year and none in another.
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 Stanley County: the model and the federal record do NOT point at the same hazard. Wildfire carries the highest modeled rating (Very Low), while the county's declaration history is led by Severe Storm. 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.

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.
