Klamath County, OR flood risk explained
Flood hazard in Klamath County sits at the 78.5th national percentile, a middling flood hazard by national standards; driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about once every 3 years. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Klamath County's flood-insurance compliance gap
FEMA hasn't published a residential structure count for Klamath County's mapped flood zone, so a reliable mandatory-compliance percentage can't be computed here — see the data quality guide for why this gap exists for roughly a quarter of US counties. Looking beyond the mandated zone, 0.2% of all residential structures in Klamath County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.

Among the 3144 US counties FEMA scores for flood hazard, Klamath County ranks 704 — 1 being the highest hazard nationally — and 785 by population among all 3144 counties covered here, where 1 is the largest.
