Risk Overview
Overall natural disaster risk in Beaver County is very low, with a National Risk Index score of 37.8 out of 100 — placing it in the 38th 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 drought (extended dry periods that stress water supplies and agriculture) at High risk — $6M in expected annual loss and about 109.91 events per year; ice storm (freezing rain that coats surfaces in heavy, damaging ice) at High risk — $1M in expected annual loss and about 0.33 events per year; and wildfire (uncontrolled fires that spread across wildland and into communities) at Low risk — $752K in expected annual loss and about 0.01 events per year. Across all hazards, FEMA estimates $12M in expected annual loss for a population of 5K.
Beyond physical exposure, Beaver County has a low social vulnerability rating (how susceptible the population is to harm) and a very low community resilience rating (its capacity to prepare for and recover from disasters). Both measures sit toward the lower end, indicating relatively modest population sensitivity.
History supports the rating: Beaver County has received 28 federal disaster declarations since 2001, including 12 for severe storm events and 7 for severe ice storm events. The most recent was Ranger Road Fire (fire), declared in February 2026.
Among 77 Oklahoma counties, Beaver County ranks #54 for overall natural disaster risk.
