How much flood risk does Lake County actually carry?
Lake County lands at the 29.8th percentile of FEMA's National Risk Index for flooding, "Very Low" territory — among the lowest flood hazard in the country — with the hazard driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about once every 4 years. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Lake County's flood-insurance compliance gap
Lake 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 Lake County, not just the ones FEMA mandates, 0.1% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
Lake County against the rest of the country
Lake County sits at rank 2264 of 3144 counties on FEMA's flood hazard scale (1 is worst) and rank 2365 of 3144 by population (1 is biggest). Lake County, Minnesota covers 2,109.108 square miles and counts roughly 10,698 residents.
