Is Lake County, OR in a flood zone?
FEMA's National Risk Index puts Lake County's flood hazard at the 37.6th percentile nationally — below the national norm for flood hazard — driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about once every 6 years. That's a county-wide figure, not a per-address one — FEMA's parcel maps are a live lookup, not a bulk file.
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, 0.6% 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 2028 of 3144 counties on FEMA's flood hazard scale (1 is worst) and rank 2559 of 3144 by population (1 is biggest). Lake County, Oregon is home to about 8,194 people across 8,138.61 square miles of land.
Checking a specific address in Lake County
