Central Missouri / Missouri River Corridor

Floodplain and low-water roads come with river-corridor property

Property along the Missouri and Gasconade rivers can sit in mapped floodplains, which affects insurance, building, and road access, so buyers should check official flood maps.

In Gasconade County, the Gasconade River flows into the Missouri River. Because of this, a lot of land here sits in or near a floodplain. A floodplain is low land next to a river that can flood. Some low roads near the rivers can flood too.

If you want to buy land along either river, ask three questions. Is the parcel in a mapped flood zone? What does that mean for flood insurance? And how do high river levels affect getting to the property?

Two official tools can help. Check the FEMA Flood Map Service Center to see if a parcel is in a flood zone. Check MoDOT’s traveler information for road closures during high water.

Look up the exact parcel before you buy. Do not assume all river-valley land has the same flood risk. Confirm what you find with the local office.
