Risk Overview

About Natural Disaster Risk in Niobrara County, Wyoming

Niobrara is Wyoming's safest county

Niobrara County scores just 3.34 on the composite risk scale, earning a Very Low rating and placing it among the safest counties in America. The county experiences roughly 95% less disaster risk than the national average.

By far Wyoming's lowest-risk county

Niobrara County's 3.34 score is dramatically lower than Wyoming's state average of 37.86, making it the clear safest county in the state. The county's low exposure across flood (6.93) and earthquake (28.40) hazards creates exceptional resilience.

Vastly safer than all surrounding counties

Niobrara County's 3.34 score is nearly unmatched in the region—Hot Springs (16.09), Johnson (19.31), and Platte (25.73) counties all face significantly higher risk. Only Niobrara maintains such minimal overall disaster exposure.

Wildfire only notable hazard

Wildfire risk reaches 80.88 in Niobrara County, making it the primary concern despite the county's overall very low risk profile. All other hazards—flood (6.93), tornado (13.52), and earthquake (28.40)—remain minimal compared to state and national standards.

Wildfire coverage makes sense here

While Niobrara County is Wyoming's safest, wildfire coverage remains worthwhile given the 80.88 risk score and the hazard's catastrophic potential. Standard homeowners insurance often excludes wildfire; a rider or separate policy provides essential protection for this singular exposure.

Risk Verdict

Natural disaster exposure in Niobrara County is lower than roughly three-quarters of U.S. counties, with a composite score at the 3th percentile. Being ranked at the 3th percentile nationally is an advantage for Niobrara County — it means fewer statistically likely events, though basic readiness ensures households are covered when exceptions occur.

Hazard Breakdown

Wildfire risk is Niobrara County's dominant natural hazard, ranked at the 81th percentile nationally under FEMA's National Risk Index. Earthquake ranks second at the 28th percentile nationally. Additional tracked hazards include tornado (14th percentile), flood (7th percentile).

Preparedness Context

At the 81th percentile nationally for wildfire, Niobrara 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. A secondary earthquake exposure at the 28th percentile nationally means Niobrara County residents face hazards from two distinct natural peril categories during different seasons. 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 Niobrara County residents can use to stay ahead of rapidly changing wildfire conditions.

Regional Context

Niobrara County is 34.5 composite risk points below the Wyoming state mean, meaning most other Wyoming counties face higher natural hazard exposure.
