Risk Overview

About Natural Disaster Risk in Hyde County, South Dakota

Hyde County has minimal disaster risk

With a composite risk score of 6.49, Hyde County ranks as very low and sits well below South Dakota's average of 26.84, placing it in the safest tier nationally. Residents face significantly less natural disaster exposure than the average American.

Among South Dakota's safest counties

Hyde County's composite score of 6.49 places it among the lowest-risk counties in South Dakota, where the state average is 26.84. The county's exposure to natural hazards is minimal compared to most of its peers statewide.

Safer than most surrounding counties

Hyde County (6.49) is significantly safer than neighboring Lake County (32.63) and only slightly riskier than Jackson County (10.18). This central South Dakota county enjoys one of the most favorable risk profiles in the region.

Wildfire remains the top hazard

Wildfire risk scores 83.72 in Hyde County—an anomalously high figure that reflects geographic and seasonal vulnerability despite the county's overall very low composite score. All other hazards, including tornado (17.81) and flood (11.45), pose minimal threats.

Basic homeowners coverage typically sufficient

Standard homeowners insurance provides adequate protection for most Hyde County residents, given the county's very low disaster risk profile. Verify coverage includes wildfire and consider preventive landscaping measures, though major supplemental insurance is unlikely necessary.

Risk Verdict

At the 6th percentile nationally, Hyde County experiences relatively limited natural hazard pressure compared to most of the country. At the 6th percentile nationally, Hyde County's natural hazard profile is comparatively favorable — community resilience is reinforced when individual households maintain a reviewed emergency plan.

Hazard Breakdown

Wildfire risk is Hyde County's dominant natural hazard, ranked at the 84th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 18th percentile nationally. Additional tracked hazards include flood (11th percentile), earthquake (9th percentile).

Preparedness Context

Hyde County's dominant hazard is wildfire, ranked at the 84th percentile nationally. Maintaining at least 30 feet of lean, clean vegetation around structures in Hyde County and keeping gutters clear of debris significantly reduces ignition risk from wind-driven embers. The county's tornado exposure at the 18th percentile nationally complements the wildfire risk — saturating rain after burn scarring often triggers secondary flood and debris flow events. Hyde County's households benefit from reviewing homeowners insurance before fire season, specifically whether the policy covers replacement cost rather than actual cash value, and whether it includes additional living expenses if displacement is required.

Regional Context

A composite score 20.4 points below the South Dakota state average puts Hyde County in a better-than-typical position relative to neighboring counties.
