Natural Disaster Risk in Castlewood

Natural Hazard Profile: Castlewood, South Dakota

Located in the interior eastern United States in Hamlin County, Castlewood is a small community of about 1,429. 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 Castlewood a community where hazard awareness has real practical value.

Castlewood's overall natural disaster risk is rated 4.5/10 (Moderate) by FEMA's National Risk Index. The area faces significant ice storm exposure, where the thermal profile of the atmosphere during winter storms frequently delivers freezing rain rather than snow. Secondary hazards include hail and cold wave.

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

Castlewood'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 ice storm exposure is adequately protected is a worthwhile step for property owners.
