The verdict

Start with the local benchmark for Dolores County: 8 FEMA declaration records are 22% below the Colorado county mean, even though the count is higher than 6% 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 safer than 11%.

Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Dolores County is led by Avalanche (about $1.8M Expected Annual Loss, Historical Loss Ratio Relatively High), while Landslide carries the highest National Risk Index rating (Relatively High). EAL and risk score use different inputs; they need not agree.

What does Dolores County's hazard record show?

Declaration frequency

The state comparison is the clearest context for Dolores County's moderate federal record. Its 8 declarations sit 22% below the Colorado county mean, with 5 Major Disaster entries among them. 3 records concern Flood, the file's most frequent incident type. Spread across 50 years, the registry rate is 0.2 per year. FEMA reports authorized programs separately from the DR, EM, and FM codes.

FEMA National Risk Index

FEMA's National Risk Index places this county in the low end of the national distribution, composite score 11.3/100 (Very Low). Expected Annual Loss is rated Very Low (roughly $4.4M in annualized losses). Two modifiers shape how that exposure becomes real-world harm here: social vulnerability (Relatively Moderate) and community resilience (Very Low). Of the 18 hazards FEMA models, Landslide stands out as the sharpest exposure here, rated Relatively High. FEMA's modeled frequency puts that hazard at roughly once every 3 years here.

Reading the federal records together

No paid-claim row for this county appears in the NFIP county table used by PlainHazard. That absence is not evidence that flooding never occurred: the register observes claims under federal flood-insurance policies, not uninsured losses, emergency reports, or every flood outside the program. The FEMA declaration history below is therefore the available federal-action record on this page.

Start with the state benchmark: a Colorado county averages 10.2 federal declaration records, while Dolores County has 8. The gap is 22% 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.

How often does each hazard strike Dolores 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
Landslide Relatively High roughly once every 3 years
Avalanche Relatively High roughly once every 2 years
Wildfire Relatively Low roughly once every 546 years
Lightning Relatively Moderate an average of 58 times per year
Drought Relatively Low 94 modeled event-days per year
Earthquake Very Low roughly once every 986 years
Winter Weather Very Low an average of 32 times per year
Riverine Flooding Very Low roughly once every 4 years
Heat Wave Very Low 0.1 modeled event-days per year
Cold Wave Very Low roughly once every 62 years
Ice Storm Very Low roughly once every 67 years
Tornado Very Low roughly once every 45 years
Hail Very Low roughly once every 8 years

What Flood declarations mean here

Flood is the most frequent declaration type on Dolores County's record, 38% 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: Landslide

Landslide risk is a function of slope, soil and water, so it is usually a SECOND-ORDER hazard: it is triggered by the rainfall, snowmelt, wildfire burn scars or seismic shaking that came first. That is why a county can carry high landslide exposure whose realized damage is recorded under a flood or storm declaration instead.

Worth noting for Dolores County: the model and the federal record do NOT point at the same hazard. Landslide carries the highest modeled rating (Relatively High), 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.

Dolores County's closest FEMA peer: Hardin County, IL

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

Which natural hazard poses the greatest risk to Dolores County?
FEMA's NRI data points to Dolores County is Landslide (risk rating: Relatively High). Other significant hazards include Avalanche (Relatively High) and Wildfire (Relatively Low). FEMA's modeled event frequency puts landslide here at roughly once every 3 years. The underlying methodology weighs historical event frequency against exposed assets and community vulnerability.
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.

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 Dolores County

Against a Colorado county mean of 10 declarations, Dolores County, CO records 8, or 22% fewer. PlainHazard classifies that historical total as moderate activity.

  • Major Disaster is the largest group (5 of 8) in a declaration history that remains below its state benchmark; frequency here is not a forecast. Colorado overview
  • Nationally the county exceeds 6% of recorded county totals, but its own Colorado benchmark is higher. The ranking keeps those two contexts separate. Most-disaster rankings
  • With no NFIP county row, the declaration register and modeled NRI remain distinct evidence rather than substitutes for a claims history. Disaster-data guide

A below-average federal record is not a safety guarantee. Use National Weather Service alerts and local emergency-management notices for present conditions, not this historical comparison.
