Malheur County, OR: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Malheur County scores at the 52th percentile for flood hazard, rated "Relatively Low" — below the national norm for flood hazard. The hazard here is driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about once every 1 years. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Malheur County's flood-insurance compliance gap
FEMA hasn't published a residential structure count for Malheur 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, 0.5% of all residential structures in Malheur County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
Where Malheur County ranks
Among the 3144 US counties FEMA scores for flood hazard, Malheur County ranks 1573 — 1 being the highest hazard nationally — and 1388 by population among all 3144 counties covered here, where 1 is the largest. Malheur County, Oregon is home to about 32,315 people across 9,887.707 square miles of land.

Where Malheur County's figures come from
Every figure on this page traces to a named FEMA dataset, documented in the methodology guide. Malheur County's compliance figure is one of the ones affected by FEMA's incomplete denominator data — the data quality guide explains what that means and how many counties it touches.
