Dunn County scores 48.79 on the national composite risk scale, placing it well below the national average and indicating relatively low overall disaster risk. This rating reflects a county that experiences natural hazards, but with manageable frequency and severity compared to the nation's most vulnerable areas.
Below Wisconsin's average risk
At 48.79, Dunn County sits significantly below Wisconsin's state average composite risk score of 59.08, making it one of the safer counties in the state for natural disasters. This puts Dunn County in a favorable position relative to peers across Wisconsin.
