Flood Zones in Lincoln County, Missouri

The June 2019 Pin Oak levee breach at Winfield

The clearest recent illustration of flood risk in this part of the county is the Pin Oak levee breach at Winfield. Water began overtopping the levee just after midnight on Sunday, June 2, 2019, and the levee failed outright by that afternoon, in five separate places along roughly a quarter-mile stretch. The Mississippi River was cresting at around 38.5 feet at the Winfield gauge -- about 12 feet above flood stage and within a foot of the highest level recorded there since the National Weather Service began keeping records in the region. Roughly 50 homes flooded as a result, and residents in and around Winfield, a town of about 1,400 people, were evacuated over the following days.

This was not an isolated event in an otherwise dry stretch: 2019 was part of a broader multi-year period of extreme Mississippi and Missouri River wetness across the state, and Winfield's levee failure sat alongside overtopping and near-overtopping events at levees elsewhere along the river that same season. For a parcel anywhere behind a levee in this stretch of Lincoln County -- particularly around Winfield and Old Monroe -- the practical lesson is that levee protection here has a documented failure point at a known, recent, and fairly moderate river stage, not merely a theoretical one calculated from an old engineering study.

A ~500-property buyout program dating to 1993 and 1995

Lincoln County's flood exposure predates 2019 by decades, and the county's response set a pattern that continues to shape its river-bottom land today. After the Great Flood of 1993 -- which displaced roughly 37,000 people statewide and caused an estimated $15 billion in damage -- and the 1995 floods that followed close behind and validated the buyout approach even to skeptics, roughly 500 properties in Lincoln County were voluntarily bought out using FEMA, state, and local funds and turned over to the county rather than rebuilt. Missouri as a whole has more FEMA flood buyouts than any other state, with roughly 80% of those buyouts tied to the 1993 flood specifically -- and Lincoln County's river-bottom communities are a meaningful part of that statewide total.

What that means for a land buyer: some parcels in the Winfield and Old Monroe area may carry a buyout history of their own, or sit adjacent to formerly-developed land that the county now holds as open floodway rather than buildable ground. A previously bought-out parcel generally cannot be redeveloped for residential use -- that is the entire point of the buyout program -- so confirm a specific tract's ownership and deed history with the Recorder of Deeds, not just its current vacant appearance, before assuming it is available for building.

What to check before buying a river-bottom or levee-protected parcel

1. Get an actual FEMA flood-zone determination for the specific parcel from the Flood Map Service Center -- do not assume from a neighboring parcel's status or from how dry the land looks on a given day.
2. Ask the Lincoln County Floodplain Administrator directly whether the parcel sits behind a levee, and if so, which levee district maintains it and what that levee's certified protection level is -- a levee's paper protection level and its demonstrated failure point (as at Pin Oak in 2019) are not always the same thing.
3. Check the Recorder of Deeds for any prior buyout, easement, or deed restriction tied to the parcel, since roughly 500 Lincoln County properties were removed from private redevelopment through the 1990s-era buyout program and some of that land remains in county or public hands today.
4. If the parcel or a structure on it has a history of flood-insurance claims, ask specifically about repetitive-loss status, which can affect both insurability and any future buyout eligibility.
5. Factor flood insurance cost and availability into your purchase math from the start if the parcel is in or near a mapped floodplain -- a low list price on river-bottom land here often reflects this risk rather than an overlooked bargain.
