Risk Overview
Crook County carries a very low composite natural disaster risk, with a National Risk Index score of 33.6 out of 100 — placing it in the 34th 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.
Risk here concentrates in wildfire (uncontrolled fires that spread across wildland and into communities) at Medium risk — $3M in expected annual loss and about 0.00 events per year; avalanche (fast-moving snow and debris sliding down steep mountain slopes) at Low risk — $101K in expected annual loss and about 0.07 events per year; and landslide (downhill movement of rock, soil, and debris on unstable slopes) at Low risk — $8K in expected annual loss and about 0.79 events per year. Across all hazards, FEMA estimates $10M in expected annual loss for a population of 25K.
Beyond physical exposure, Crook County has a medium social vulnerability rating (how susceptible the population is to harm) and a high community resilience rating (its capacity to prepare for and recover from disasters). A less vulnerable population paired with strong resilience helps the community absorb and recover from events.
The county's disaster history tells the same story: Crook County has received 11 federal disaster declarations since 1964, including 3 for severe storm events and 2 for fire events. The most recent was Highland Fire (fire), declared in July 2025.
Among 36 Oregon counties, Crook County ranks #27 for overall natural disaster risk.
