Humphreys County, TN flood risk explained
Flood hazard in Humphreys County sits at the 46th 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 1 years.

Mandatory flood insurance compliance in Humphreys County
14.2% of the homes FEMA requires to carry flood insurance in Humphreys County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 61 policies against 429 mandated structures, which means a meaningful share of legally-required coverage simply isn't there.
