How Putnam County floods

Putnam County experiences a flood risk profile dominated by riverine floods and flash flooding from slow-moving summer thunderstorms.

Recent history illustrates these localized hazards, including a flash flood on June 12, 2022, when storms tracking along the I-74 corridor produced a road washout in northwestern Putnam County. Another heavy rainfall event on August 13, 2016, produced flash flooding reports as bands of showers and thunderstorms moved across central Indiana.

NFIP claim records reflect financial impacts across different zones. Properties in Zone A experienced 15 claims with an average recorded water depth of 4 inches and an average payout of $24,188. Meanwhile, properties in Zone X_UNSHADED recorded 2 claims with an average water depth of 12 inches and an average payout of $176,053. Homeowners, real estate agents, and journalists should pay the closest attention to properties located within designated Zone A high-risk areas, as well as unshaded Zone X properties that have shown potential for significant localized water depths during severe storms.

From the storm reports

Flood · Jun 14, 2025. Multiple rounds of slow-moving storms impacted much of north central Indiana during the late overnight and morning hours of June 14th with rain totals as high as 6 inches. Numerous roads were closed with the most severe flooding noted on the south side of Kokomo. This flooding led to minor flooding along the Wildcat creek basin and the upper Wabash and upper White rivers.

Flash Flood · Apr 5, 2025. The final round of rain in a stretch of 4 days brought rain amounts of 2-4.5 inches of rain to central Indiana in addition to the 3-5 inches that had fallen. This led to additional widespread flash flooding and exacerbated ongoing creek and river flooding to a point that many main stem rivers ended up reaching major flood stage.

Flash Flood · Jun 12, 2022. West-northwesterly winds along a slowly-advancing warm frontal zone promoted the ample bulk shear and copious instability that produced numerous morning showers and thunderstorms. Storms tracked eastward along the I-74 corridor, producing isolated large hail, and later isolated wind damage and flash flooding. A road was washed-out in a possible microburst over northwestern Putnam County. All severe cells occurr…

Flash Flood · Aug 13, 2016. Bands of showers and thunderstorms, oriented from southwest to northeast, affected portions of central Indiana during the late morning through mid-afternoon of August 13th. Heavy downpours produced a couple flash flooding reports during the early to mid-afternoon timeframe.

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.
  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.

Flood insurance in Putnam County

If a building in Putnam 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.
