The verdict
Start with the local benchmark for Green Lake County: 9 FEMA declaration records are 27% below the Wisconsin county mean, even though the count is higher than 8% of counties in the national registry. On FEMA's distinct National Risk Index model, which combines expected loss with vulnerability and resilience, the county ranks in the riskiest 42%.

Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Green Lake County is led by Riverine Flooding (about $7.0M Expected Annual Loss, Historical Loss Ratio Relatively High), while Hail carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

What does Green Lake County's hazard record show?
Reading the federal records together
The NFIP claims register shows a middle-volume loss record here: 53 paid claims, totaling $470.7K. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $8.9K average describes payments on recorded claims only, leaving uninsured damage and properties without a claim outside the measure.
Start with the state benchmark: a Wisconsin county averages 12.3 federal declaration records, while Green Lake County has 9. The gap is 27% 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
This county carries a high composite score on FEMA's National Risk Index, 58.0/100, rated Relatively Low. Its Expected Annual Loss rating is Very Low (roughly $14.2M in annualized losses), and a Very High social-vulnerability profile combined with Relatively High community resilience shapes how much of that raw exposure becomes realized harm. Among the 18 modeled hazards, Hail carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at an average of 3.7 times per year here, based on 142 historical events on record.
Declaration frequency
The state comparison is the clearest context for Green Lake County's moderate federal record. Its 9 declarations sit 27% below the Wisconsin county mean, with 6 Major Disaster entries among them. 3 records concern Severe Storm, the file's most frequent incident type. Spread across 47 years, the registry rate is 0.2 per year. FEMA reports authorized programs separately from the DR, EM, and FM codes.

How often does each hazard strike Green Lake 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 Moderate | an average of 3.7 times per year |
| Cold Wave | Relatively Moderate | an average of 6.3 times per year |
| Tornado | Relatively Moderate | roughly once every 4 years |
| Strong Wind | Relatively Moderate | an average of 3.7 times per year |
| Riverine Flooding | Relatively Low | roughly once every 2 years |
| Heat Wave | Relatively Low | 2.7 modeled event-days per year |
| Wildfire | Very Low | roughly once every 2,771 years |
| Landslide | Very Low | roughly once every 18 years |
| Drought | Relatively Low | 1.7 modeled event-days per year |
| Winter Weather | Relatively Low | an average of 15 times per year |
| Lightning | Relatively Low | an average of 34 times per year |
| Earthquake | Very Low | roughly once every 2,092 years |
| Ice Storm | Very Low | roughly once every 4 years |
| Hurricane | Very Low | roughly once every 100 years |

What Severe Storm declarations mean here
Severe Storm is the most frequent declaration type on Green Lake County's record, 33% 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: 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.
For Green Lake County the two measures on this page point the same way: Hail is the county's highest-rated modeled hazard (Relatively Moderate), and Severe Storm declarations also lead its federal record. Where the model and the declaration history agree, the reading is comparatively straightforward, the hazard is both expected and repeatedly realised.
National Risk Index ratings are modeled estimates of expected annual loss, not predictions of what will happen in any given year.
