The verdict

Two federal records point in the busier direction for Lake County. Its 35 FEMA declarations are 23% above the California county mean and exceed the count for 93% of the 3,266 counties in this registry. Separately, FEMA's National Risk Index places it in the riskiest 7%, based on modeled expected annual loss, social vulnerability, and community resilience.

Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Lake County is led by Riverine Flooding (about $51.5M Expected Annual Loss, Historical Loss Ratio Relatively Moderate), while Wildfire carries the highest National Risk Index rating (Relatively High). EAL and risk score use different inputs; they need not agree.

What does Lake County's hazard record show?

Reading the federal records together

FEMA's NFIP table contains a substantial paid-claim history for this county: 1,432 claims and $14.2M in payments. PlainHazard labels 500 or more claims a heavy registry record; that is a reporting bucket, not an official FEMA risk grade. The average paid claim was $9.9K. NFIP totals exclude uninsured flood losses and do not measure how many properties currently carry a policy.

The declaration register points in the busier direction. Lake County's 35 federal records stand 23% above the California county mean of 28.5. 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 sits among the highest-risk counties nationally on FEMA's National Risk Index, a composite score of 93.0/100 (Relatively Moderate). Expected Annual Loss is rated Relatively Moderate (roughly $101.0M in annualized losses). Social vulnerability reads Relatively High and community resilience Relatively Low, both critical modifiers of realized harm here. Of the 18 hazards FEMA models, Wildfire stands out as the sharpest exposure here, rated Relatively High. FEMA's modeled frequency puts that hazard at roughly once every 59 years here.

Declaration frequency

The FEMA register is busy by both local and national comparisons. It contains 35 entries for Lake County, including 20 Major Disaster records, 23% above the California county mean. Across the 59-year span, that works out to 0.6 declarations a year. Fire leads the file with 15 entries. Declaration type records the federal action taken, not every assistance program approved.

How often does each hazard strike 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
Wildfire Relatively High roughly once every 59 years
Landslide Relatively High an average of 94 times per year
Earthquake Relatively Moderate roughly once every 12 years
Volcanic Activity Relatively Moderate roughly once every 10,000 years
Drought Relatively High 60 modeled event-days per year
Riverine Flooding Relatively High roughly once every 2 years
Avalanche Relatively High roughly once every 8 years
Heat Wave Relatively Low 6.7 modeled event-days per year
Winter Weather Relatively Low an average of 8.8 times per year
Lightning Very Low an average of 5.4 times per year
Tornado Very Low roughly once every 10 years

What Fire declarations mean here

Fire is the most frequent declaration type on Lake County's record, 43% of its declarations. Wildfire is the one hazard here with its own dedicated federal instrument: the Fire Management Assistance Grant, which appears in this data as an FM record. An FMAG can be authorised while a fire is still burning, on a timescale of hours, because its purpose is to reimburse the cost of fighting a fire that threatens to become a major disaster.

That distinction matters when comparing counties. An FM declaration is not a presidential major disaster declaration and does not carry the same assistance programmes, so a fire-heavy county's total is not directly comparable with a hurricane-heavy county's total unless the declaration types are separated, which is why they are listed separately on this page.

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.

For Lake County the two measures on this page point the same way: Wildfire is the county's highest-rated modeled hazard (Relatively High), and Fire 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.

Data-matched county comparisons

Lake County's closest FEMA peer: Lafayette County, FL

Comparisons use published FEMA declaration fields plus the National Risk Index composite for Lake 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.

The most active year for disaster declarations in Lake County was 2018, with 5 declarations. The county has FEMA disaster data spanning 1965 to 2024.
What is the FEMA National Risk Index score for Lake County?
According to the FEMA National Risk Index, Lake County, California has an overall risk score of 93.0 out of 100 (Relatively Moderate). On social vulnerability the county rates Relatively High; on community resilience, Relatively Low. The Expected Annual Loss (EAL) score is Relatively Moderate, representing $101.0M in annualized losses.
Which natural hazard poses the greatest risk to Lake County?
The top hazard flagged by FEMA's NRI for Lake County as of the latest release is Wildfire (risk rating: Relatively High). Other significant hazards include Landslide (Relatively High) and Earthquake (Relatively Moderate). FEMA's modeled event frequency puts wildfire here at roughly once every 59 years.

Data Sources & Methodology

Disaster declaration data comes from the FEMA OpenFEMA Disaster Declarations Summaries v2 API, which includes all federally declared disasters, emergencies, and fire management assistance grants.

Storm event data is sourced from the NOAA Storm Events Database (2015-2025), which tracks significant weather events including thunderstorms, tornadoes, floods, and winter storms.

Flood insurance data comes from the FEMA National Flood Insurance Program (NFIP) OpenFEMA claims dataset.

This data is provided for informational purposes only. FEMA disaster declarations represent federal response actions and may not capture all local emergencies or weather events.

What this means for Lake County

Lake County, CA has 35 federal declaration records, 23% more than the California county mean of 29; its history sits in PlainHazard's high activity band.

  • Within this above-state-average declaration file, major disaster leads with 20 of 35 records; the category describes past federal action, not the next likely hazard. California overview
  • The state benchmark and national rank point the same way: this count tops the California mean and the totals for 93% of 3,266 U.S. counties. Most-disaster rankings
  • The large NFIP claims file and FEMA declaration history measure different federal records; the guide explains where they overlap and where they do not. Disaster-data guide

An above-average declaration count records past federal responses; it does not predict the next event. Current warnings come from the National Weather Service and local emergency officials.
