Is Watonwan County, MN in a flood zone?
FEMA's National Risk Index puts Watonwan County's flood hazard at the 24.9th percentile nationally — among the lowest flood hazard in the country — driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about once every 2 years. That's a county-wide figure, not a per-address one — FEMA's parcel maps are a live lookup, not a bulk file.
