Risk Overview

Overall natural disaster risk in Bear Lake County is very low, with a National Risk Index score of 6.6 out of 100 — placing it in the 7th national percentile and among the lowest-risk counties in the country. The score blends Expected Annual Loss, Social Vulnerability, and Community Resilience across all 18 FEMA hazard types.

The county's risk is driven primarily by avalanche (fast-moving snow and debris sliding down steep mountain slopes) at Medium risk — $1M in expected annual loss and about 0.10 events per year; landslide (downhill movement of rock, soil, and debris on unstable slopes) at Low risk — $29K in expected annual loss and about 1.04 events per year; and wildfire (uncontrolled fires that spread across wildland and into communities) at Low risk — $479K in expected annual loss and about 0.00 events per year. Across all hazards, FEMA estimates $5M in expected annual loss for a population of 6K.

Beyond physical exposure, Bear Lake County has a very low social vulnerability rating (how susceptible the population is to harm) and a medium community resilience rating (its capacity to prepare for and recover from disasters). Both measures sit toward the lower end, indicating relatively modest population sensitivity.

The federal record bears this out: Bear Lake County has received 4 federal disaster declarations since 1977, including 2 for biological events and 1 for hurricane events. The most recent was Covid-19 Pandemic (biological), declared in April 2020.

Among 44 Idaho counties, Bear Lake County ranks #39 for overall natural disaster risk.
