Risk Overview
Overall natural disaster risk in Trego County is very low, with a National Risk Index score of 2.7 out of 100 — placing it in the 3rd 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 hail (ice stones from severe thunderstorms that damage property and crops) at Low risk — $628K in expected annual loss and about 9.32 events per year; drought (extended dry periods that stress water supplies and agriculture) at Low risk — $510K in expected annual loss and about 77.32 events per year; and wildfire (uncontrolled fires that spread across wildland and into communities) at Very Low risk — $56K in expected annual loss and about 0.00 events per year. Across all hazards, FEMA estimates $3M in expected annual loss for a population of 3K.
Beyond physical exposure, Trego County has a very low 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: Trego County has received 13 federal disaster declarations since 1993, including 6 for severe storm events and 2 for biological events. The most recent was Severe Winter Storm (winter storm), declared in April 2024.
