Ste. Genevieve floodplain questions start with the Mississippi River

Ste. Genevieve sits near the Mississippi River, and the river shapes flood questions for the historic town and nearby bottomland. A pretty old street, farm tract, or river-adjacent lot can still need a flood-map check.

For anyone buying or insuring property near the river, the specific parcel is worth checking at the FEMA Flood Map Service Center. A levee does not cover every address. Levee-protected areas can still carry residual risk, and flood-zone status can matter for insurance and building decisions.

Current river-stage numbers change all the time. The durable question is where the parcel sits on the official flood map, plus what local floodplain or levee information applies to that address.
