How Marshall County floods

Marshall County experiences a flood risk profile dominated by flash floods and general floods, with the NOAA Storm Events Database recording 38 flash flood and 34 flood events (including 1 death) over the last 30 years. Recent events illustrate this pattern, including a January 2025 low pressure system that brought moderate to heavy rain and 3 to 4 inches of storm total precipitation, as well as significant flash flooding driven by steady, wave-based rains over a stationary warm front in February 2025.

Federal Emergency Management Agency National Flood Insurance Program records show claims across multiple zones. Zone A accounts for 41 claims with an average payout of $21,164 and an average recorded water depth of 4 inches. Zone X accounts for 16 claims with an average payout of $29,992 and an average recorded water depth of 3 inches, while Zone X_UNSHADED has 7 claims averaging a $3,237 payout with an average water depth of 2 inches. Zone X_SHADED recorded 2 claims averaging $11,339 with an average water depth of 1 inch, and Zone UNKNOWN logged 2 claims averaging $270 with an average water depth of 1 inch.

Homeowners, real estate agents, and journalists should pay the closest attention to properties located within FEMA Zone A, which holds the highest concentration of historical insurance claims, as well as those in Zone X where average payouts have been highest.

Significant flash flooding occurred over west Kentucky, as anomalously high amounts of low-level moisture streamed northward over a warm front that became stationary along the Tennessee border. Steady rains began just after 0000CST on the 15th and continued until around 0100CST on the 16th.

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.

Flood insurance in Marshall County

If a building in Marshall 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.
