Natural Disaster Risk in Harrison

Natural Hazard Profile: Harrison, South Dakota

Located in the interior eastern United States in Douglas County, Harrison is a small unincorporated community. The semi-arid continental climate that characterizes this part of South Dakota — marked by harsh winters, hot summers, and significant seasonal variation — directly influences the types and severity of natural hazards present, making Harrison a community where hazard awareness has real practical value.

FEMA rates Harrison's composite natural disaster risk at 4.6 out of 10 — moderate risk. Drought is the leading natural hazard, with multi-year dry periods capable of depleting water supplies, devastating agriculture, and increasing wildfire risk across the region. Residents should also account for ice storm and cold wave risk in their preparedness planning.

Relative to other U.S. communities, Harrison's natural disaster risk is near the U.S. national average of 4.5/10, near the 4.9/10 state average. The hazard distribution here is led by drought and ice storm, as measured by FEMA across Douglas County. While city-specific sub-county variation exists, these scores represent the best available federal risk estimate.

With a moderate risk rating, Harrison residents are well-served by maintaining standard preparedness practices — an emergency supply kit, awareness of local hazard seasonality, and insurance that covers the top local risks. Periodic review of coverage for drought is recommended.
