Is Iron County, WI in a flood zone?
FEMA's National Risk Index puts Iron County's flood hazard at the 21.8th percentile nationally — among the lowest flood hazard in the country — split between inland river flooding (about once every 3 years) and coastal storm surge (about once every 65 years). County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Who actually carries the flood insurance FEMA requires
Iron County is one of the counties where FEMA's own denominator for mandated flood-zone structures is missing, so no compliance rate is shown rather than a guessed one — the data quality guide covers how common this is. Across all residential structures in Iron County, not just the ones FEMA mandates, 0.4% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
How Iron County compares nationally
Iron County sits at rank 2503 of 3144 counties on FEMA's flood hazard scale (1 is worst) and rank 2718 of 3144 by population (1 is biggest). About 6,235 people live in Iron County, Wisconsin, spread over 758.214 square miles.
