Risk Overview

About Natural Disaster Risk in Clearwater County, Idaho

Clearwater County faces above-average risk

With a composite risk score of 46.91 and a Relatively Low rating, Clearwater County exceeds the national average for natural disaster exposure. The county's position reflects significant wildfire and flood vulnerability in a mountainous, forested landscape.

Ranking higher risk than most Idaho counties

Clearwater County's score of 46.91 sits well above Idaho's state average of 38.51, placing it in the higher-risk tier for the state. Only a handful of Idaho counties face comparable or greater hazard exposure.

Wildfire risk unites the region

Clearwater County's wildfire risk of 96.41 aligns with nearby Elmore (97.65) and Gem (96.50) counties, reflecting the region's shared forest fire exposure. All three counties face extreme wildfire pressure despite differences in other hazard types.

Wildfire and flood dominate the hazard profile

Wildfire risk at 96.41 and flood risk at 55.73 are Clearwater County's primary concerns, with earthquake (22.96) and tornado (3.44) playing minor roles. This combination reflects the county's mountain terrain and river valleys.

Wildfire and flood insurance are essential

Clearwater County residents should secure comprehensive homeowners coverage that includes wildfire (often a separate rider) and flood insurance through NFIP or private insurers. Properties near waterways or forested slopes face compounded risk and deserve immediate policy review.

Risk Advisory: Clearwater County

Risk Verdict

At the 47th percentile nationally, Clearwater County experiences a manageable level of natural hazard risk that falls below the U.S. median. A preparedness foundation — alert registration, household communication plan, and a basic supply review — costs little and remains valuable even at Clearwater County's favorable 47th percentile ranking.

Hazard Breakdown

Wildfire risk is Clearwater County's dominant natural hazard, ranked at the 96th percentile nationally under FEMA's National Risk Index. Flood ranks second at the 56th percentile nationally. Additional tracked hazards include earthquake (23th percentile), tornado (3th percentile).

Preparedness Context

Wildfire ranks as Clearwater County's primary hazard at the 96th percentile nationally. For Clearwater County households in high-WUI areas, go-bag readiness — the ability to leave within 15 minutes — is more important than shelter-in-place planning for most residential properties. Alongside wildfire, flood at the 56th percentile nationally means a multi-season preparedness mindset — fire season and flood or storm season often require different household plans. Clearwater County county's local emergency management office publishes community-specific wildfire risk assessments and evacuation zone maps; households should review their zone assignment and sign up for zone-specific alerts.

Regional Context

Clearwater County falls 8.4 points above Idaho's typical county risk level, which means the hazard environment here is notably more demanding than the state baseline.
