Risk Overview

About Natural Disaster Risk in Ouray County, Colorado

Ouray County's Risk: Well Below National Average

Ouray County's composite risk score of 17.72 places it in the "Very Low" category, roughly one-third the national average natural disaster risk. The county's small, mountainous geography and limited development create one of Colorado's safest natural disaster profiles.

Among Colorado's Lowest-Risk Counties

Ouray County's composite score of 17.72 ranks it among Colorado's safest counties, well below the state average of 40.67. Only Mineral County scores lower, reflecting Ouray's remote San Juan Mountains location and sparse population.

Significantly Safer Than Surrounding Counties

Ouray County's 17.72 score stands well below neighboring Montrose (49.01) and Montezuma (47.61) counties, roughly one-third their risk levels. This dramatic difference reflects Ouray's higher elevation, smaller population, and lower exposure to flood and tornado hazards.

Wildfire Your Primary Risk; Earthquake Secondary

Wildfire risk at 71.85 is Ouray County's highest hazard score, reflecting forest coverage in the San Juan Mountains, though overall county risk remains very low. Earthquake risk (27.93) ranks second, while tornado (2.64) and flood (24.68) risks are minimal.

Wildfire Coverage Recommended Despite Low Risk

Even in low-risk Ouray County, homeowners in or near forested areas should add wildfire coverage to their policies, as standard homeowners insurance excludes this peril. Earthquake insurance is optional given your county's 27.93 earthquake score, but worth evaluating if your home is older or in a seismic zone.

Risk Verdict

Natural disaster exposure in Ouray County is lower than roughly three-quarters of U.S. counties, with a composite score at the 18th percentile. The 18th percentile national ranking is one lens; Ouray County residents also benefit from reviewing which specific hazard types drive the county's composite score and preparing accordingly.

Hazard Breakdown

Wildfire risk is Ouray County's dominant natural hazard, ranked at the 72th percentile nationally under FEMA's National Risk Index. Earthquake ranks second at the 28th percentile nationally. Additional tracked hazards include flood (25th percentile), tornado (3th percentile).

Preparedness Context

At the 72th percentile nationally for wildfire, Ouray County residents should verify whether their insurance policy includes replacement cost coverage for structures and whether the insurer still writes new policies in this fire-risk zone. Alongside wildfire, earthquake at the 28th percentile nationally means a multi-season preparedness mindset — fire season and flood or storm season often require different household plans. Local USFS or Cal Fire (where applicable) fire risk maps and seasonal Red Flag Warning alerts from the National Weather Service are two free resources Ouray County residents can use to stay ahead of rapidly changing wildfire conditions.

Regional Context

Ouray County is 23.0 composite risk points below the Colorado state mean, meaning most other Colorado counties face higher natural hazard exposure.
