Central Missouri / Missouri River Corridor
The southern edge drops into the Missouri River bottoms and Loutre Island
Montgomery County's southern boundary follows the Missouri River, and the bottoms and Loutre Island area sit in the floodplain, so flood-zone status is a real buying question there even though the I-70 uplands are dry
Montgomery County runs from the rolling I-70 uplands down to the Missouri River, which forms much of its southern boundary. The river bottoms and the Loutre Island area sit in the floodplain, so a parcel near the river can carry a very different flood story than one up by Montgomery City or Danville. Near the bottoms, a FEMA flood-zone designation is the first thing to check, because it shapes flood-insurance expectations and lender requirements, and it does not change with a single dry season. The FEMA Flood Map Service Center is the official place to look up a specific address, and any levee or drainage district in the bottoms can affect how a parcel drains. The practical move is to check flood-zone status early when buying in the southern part of the county rather than judging by recent weather.
