Spink County's FEMA Risk Index score
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Spink County is led by Riverine Flooding (about $4.3M Expected Annual Loss, Historical Loss Ratio Relatively High), while Hail carries the highest National Risk Index rating (Relatively Low). EAL and risk score use different inputs; they need not agree.

What does Spink County's hazard record show?
Reading the federal records together
The NFIP claims register shows a middle-volume loss record here: 74 paid claims, totaling $970.2K. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $13.1K 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. Spink County's 23 federal records stand 21% above the South Dakota county mean of 19.0. 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
This county's FEMA National Risk Index composite lands at 17.7/100 (Very Low), a modest reading against the rest of the country. Expected Annual Loss is rated Very Low (roughly $9.7M in annualized losses), tempered or compounded by a Very Low social-vulnerability score and Relatively High community-resilience score. Even the county's top-rated hazard, Hail, only reaches Relatively Low on FEMA's scale, none of the 18 modeled hazards stand out here. FEMA's modeled frequency puts that hazard at an average of 4.3 times per year here, based on 165 historical events on record.

How often does each hazard strike Spink 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 |
|---|---|---|
| Hail | Relatively Low | an average of 4.3 times per year |
| Cold Wave | Relatively Moderate | an average of 12 times per year |
| Wildfire | Relatively Low | roughly once every 1,035 years |
| Winter Weather | Relatively Moderate | an average of 21 times per year |
| Ice Storm | Relatively Low | roughly once every 2 years |
| Drought | Relatively Low | 1.9 modeled event-days per year |
| Tornado | Relatively Low | roughly once every 1 years |
| Landslide | Very Low | roughly once every 7 years |
| Riverine Flooding | Very Low | an average of 3.3 times per year |
| Heat Wave | Very Low | 4.5 modeled event-days per year |
| Strong Wind | Very Low | an average of 2.9 times per year |
| Earthquake | Very Low | roughly once every 3,195 years |
| Lightning | Very Low | an average of 33 times per year |

What Flood declarations mean here
Flood is the most frequent declaration type on Spink County's record, 39% 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: Hail
Hail is among the most expensive hazards in the model relative to how little it threatens life. It concentrates on roofs, vehicles and crops, and a single severe storm can generate an insurance loss across a metropolitan area without a single injury.
Worth noting for Spink County: the model and the federal record do NOT point at the same hazard. Hail carries the highest modeled rating (Relatively Low), 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.
