Risk Overview

About Natural Disaster Risk in Clay County, Minnesota

Clay County faces elevated U.S. disaster risk

Clay County's composite risk score of 73.66 with a "Relatively Low" rating places it well above the national average, indicating substantial exposure to multiple natural hazards. The county ranks among America's higher-risk regions, particularly for flooding and wildfire.

Clay ranks among Minnesota's riskiest counties

Clay County scores 73.66, significantly exceeding Minnesota's state average of 42.38 by 74 percent, making it one of the state's most disaster-prone counties. This elevation reflects the county's northwestern Minnesota geography and susceptibility to water-based and fire hazards.

Clay is the region's highest-risk county by far

Clay County (73.66) substantially exceeds neighboring Carlton (70.07), Chisago (44.53), and Chippewa (36.99), making it the region's clear risk leader. The county's extreme flood risk of 82.44 drives much of this elevation.

Flooding is Clay's defining natural disaster threat

Clay County's flood risk score of 82.44 is exceptionally high, reflecting the county's location in the Red River Valley with its documented flooding history. Wildfire (65.97) and tornado (62.02) risks compound the flood threat, creating a multi-hazard environment.

Flood insurance is non-negotiable for Clay residents

Clay County homeowners must secure flood insurance immediately, as the 82.44 flood risk score indicates severe and frequent inundation exposure—standard policies will not cover flood losses. Additionally, maintain wildfire defensibility and review tornado preparedness given the county's three-pronged hazard profile.

Hazard Breakdown

Flood risk is Clay County's dominant natural hazard, ranked at the 82th percentile nationally under FEMA's National Risk Index. Wildfire ranks second at the 66th percentile nationally. Additional tracked hazards include tornado (62th percentile), earthquake (15th percentile).

Preparedness Context

Clay County's top natural hazard is flood risk, ranked at the 82th percentile nationally.

Alongside flooding, wildfire exposure at the 66th percentile means households benefit from a multi-hazard preparedness plan rather than focusing on flood alone. For most Clay County households, the highest-return preparedness step is storing critical documents in digital cloud backup combined with a pre-designated family meeting point if communication is disrupted.

Regional Context

Clay County's composite risk score sits 31.3 points above the Minnesota county average, placing it among the more hazard-exposed counties in the state.
