How Woodson County floods

Flash flooding from summer thunderstorms dominates the flood risk profile in Woodson County, Kansas, accounting for the vast majority of historical flood events over the last thirty years compared to general river floods.

Severe weather patterns have repeatedly brought heavy rainfall and localized flooding to the region. For instance, a weak boundary triggered strong thunderstorms and very heavy rainfall during the late night hours of July 12, 2023, causing localized flooding. Similarly, a prolonged period of severe thunderstorms brought flash flooding across Southeast Kansas on May 24, 2019, persisting into the following day.

Homeowners, real estate agents, and journalists monitoring property risk in the area should pay the closest attention to properties situated near smaller creeks, low-lying areas, and locations prone to rapid runoff during intense summer storm systems.

From the storm reports

Flash Flood · Jun 3, 2025. Thunderstorms developed across south-central Kansas during the morning hours of June 3rd and slowly moved to the northeast. Additional rounds of thunderstorms developed and trained across portions of south-central and southeast Kansas. Numerous reports of flash-flooding were observed across the area with significant flooding across Sedgwick and Butler counties.

Flash Flood · Jul 13, 2023. During the late night hours of July 12th, a weak boundary sagged into southeast Kansas which helped to trigger strong to severe thunderstorms across that area. Severe winds around 60 to 65 mph and very heavy rainfall which caused flooding in some areas.

Flood · Jul 16, 2021. Showers and thunderstorms dropped copious amounts of rain across the county warning area prompting several flood warnings and one flash flood warning in Montgomery county.

Flash Flood · May 24, 2019. A prolonged period of severe thunderstorms that produced a grand slam of flash floods, large hail, damaging winds & even a couple tornadoes hit nearly all of the Wichita (ICT) County Warning Area (CWA) throughout the afternoon & night on the 24th. Of the severe thunderstorm modes, floods & flash floods proved to be, by far, the greatest threat to these areas. The flash flooding continued across primarily Southeast…

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. The floodway is the channel and the land beside it; the 1%-annual-chance flood surface (the base flood elevation) covers the valley floor as zone A or AE; a narrow band higher up is shaded X, the 0.2% floodplain; higher ground is X.0.2% CHANCE A YEAR (500-YEAR)BASE FLOOD ELEVATION · 1% A YEARXAEFloodwayAEX
  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.
  2. Floodway The channel and the land beside it that has to be kept clear enough to carry the flood. Building here is tightly limited.
  3. X shaded The 0.2% (500-year) floodplain, plus some levee-protected and very shallow flood areas.
  4. X Outside both lines. No federal requirement to insure, which is not the same as no risk.

Flood insurance in Woodson County

If a building in Woodson 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.
