How Carter County floods

Flash flooding and standard flooding occur with nearly equal frequency in Carter County, driven by 30 flash flood events, including 1 recorded death, and 32 general flood events over the last 30 years. Heavy rainfall events are frequently produced by slow-moving frontal boundaries and severe weather outbreaks. For example, a severe weather outbreak on May 26, 2024, brought heavy rainfall and flooding to the region, while multiple rounds of training heavy rain from November 4 through 6, 2024, dropped 4 to 6 inches of rainfall in Carter County, causing street flooding in Van Buren and affecting water levels on the Current and St. Francis Rivers. A separate event on September 23, 2025, produced heavy rains and flooding in southeastern Carter County.

National Flood Insurance Program records show claims across multiple zones, with the highest volume concentrated in Zone A with 90 claims averaging a $40,260 payout and an average recorded water depth of 8 inches. Properties outside mapped high-risk areas also face financial exposure, notably in Zone X, where 6 claims averaged a $210,262 payout and an average recorded water depth of 18 inches, and unshaded Zone X, where 8 claims averaged a $137,741 payout with an average water depth of 6 inches. Zone UNKNOWN recorded 19 claims with an average payout of $23,144 and an average water depth of 8 inches. Property owners in Zone A, as well as owners of higher-value structures in Zone X and unshaded Zone X experiencing deep inundation, should pay the closest attention to these flood risks.

Flood · Sep 23, 2025. A boundary stretching across portions of Southeast Missouri resulted in thunderstorms with heavy rain during the early morning hours of the 23rd from Carter County southeastward to New Madrid. A broader area of rainfall arrived late morning which produced additional heavy rains. Flooding issues developed in Southeastern Carter County which received some of the higher totals from both rounds. Precipitable water val…

Flash Flood · May 26, 2024. The second major severe weather outbreak for the month occurred on the 26th for the Quad State region. On the synoptic scale, a shortwave trough centered in the middle of the country with a 60 kt mid-level jet moved across northern Arkansas. A weak surface low was moving into SE Missouri during the morning with a secondary low located further northwest. A warm frontal boundary was draped across our area. A bowing…

The zones you’ll see on the map

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.

Cross-section of a river floodplainDiagram: a river valley.

  1. A / AE Inside the 1%-a-year floodplain: about a 26% chance of flooding over a 30-year mortgage. AE has a mapped base flood elevation; plain A does not.

Flood insurance in Carter County

If a building in Carter County is in a high-risk zone (A or V) and its mortgage comes from a federally regulated or insured lender, or is federally backed, flood insurance is required.

Outside those zones it is optional, and often worth having: from 2014 to 2024 nearly one-third of NFIP claims came from outside the high-risk Special Flood Hazard Area. Since Risk Rating 2.0, NFIP premiums are set for each building, so the only reliable price is a quote: FloodSmart.gov or a local agent.
