Chouteau County, MT flood risk explained
Flood hazard in Chouteau County sits at the 50.4th national percentile, 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 4 years. That's a county-wide figure, not a per-address one — FEMA's parcel maps are a live lookup, not a bulk file.
Chouteau County's flood-insurance compliance gap
FEMA hasn't published a residential structure count for Chouteau 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, 0.1% of all residential structures in Chouteau County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
How Chouteau County compares nationally
Among the 3144 US counties FEMA scores for flood hazard, Chouteau County ranks 1623 — 1 being the highest hazard nationally — and 2740 by population among all 3144 counties covered here, where 1 is the largest. About 5,880 people live in Chouteau County, Montana, spread over 3,972.52 square miles.
Your street may differ from Chouteau County's average
