Natural Disaster Risk in Island Park

Natural Hazard Profile: Island Park, Idaho

Located in the Great Plains in Fremont County, Island Park is a small community of about 628. The semi-arid climate that characterizes this part of Idaho — marked by dry summers, cold winters, and significant wildfire risk — directly influences the types and severity of natural hazards present, making Island Park a community where hazard awareness has real practical value.

FEMA rates Island Park's composite natural disaster risk at 5.5 out of 10 — moderate risk. Avalanche risk is the dominant natural hazard, with steep mountain terrain and heavy seasonal snowpack creating conditions for dangerous snow slides in and around the area. Residents should also account for volcano and wildfire risk in their preparedness planning.

Relative to other U.S. communities, Island Park's natural disaster risk is above the U.S. national average of 4.5/10, slightly above the 5.1/10 state average. The hazard distribution here is led by avalanche and volcano, as measured by FEMA across Fremont County. While city-specific sub-county variation exists, these scores represent the best available federal risk estimate.

Island Park's moderate risk profile means that while catastrophic events are less frequent, they do occur. Standard homeowners insurance typically covers many common hazards here, but confirming that avalanche exposure is adequately protected is a worthwhile step for property owners.
