How Bartholomew County floods

Riverine flooding and flash flooding from severe storms dominate the flood risks in Bartholomew County, with NOAA records detailing 39 flood events and 19 flash flood events over the last 30 years, resulting in a total of four deaths. Multi-day heavy rainfall events frequently drive this hazard, as demonstrated in April 2025 when consecutive rounds of rain totaling up to 9.5 inches caused widespread flash flooding and pushed main stem rivers to major flood stages. Another severe multi-faceted system struck the region in June 2021, producing flash flooding that resulted in a fatality.

National Flood Insurance Program records show that properties situated in high-risk Zone A face the heaviest concentration of risk, accounting for 429 claims with an average payout of $34,003 and an average recorded water depth of 19 inches. However, properties outside designated high-risk zones also experience losses; Zone X properties recorded 45 claims averaging $49,926 and an average water depth of 16 inches, while Zone X shaded properties recorded 6 claims with an average water depth of 36 inches. Homeowners, real estate agents, and journalists should pay the closest attention to properties located near rivers and streams within Zone A, as well as properties in shaded Zone X areas where significant localized water depths have been recorded.

Where the flood claims came from

From the storm reports

Flood · Apr 6, 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 · Jul 29, 2021. A very warm and humid air mass combined with a slowly-approaching west-to-east cold front to initiate scattered evening thunderstorms. Severe weather occurred in the most favorable environment, to the southeast of Indianapolis, wherein 3000-4000 MLCAPE, 125-175 0-3 km MLCAPE, and 100-200 effective storm relative helicity combined to form an intense, nearly-stationary QLCS. Two EF-1 tornadoes, spawned from the QL…

Flash Flood · Jun 19, 2021. A long lasting and multi faceted storm system moved through central Indiana beginning during the late afternoon hours of June 18th and continued through the evening hours with widespread damaging winds and very large hail before transitioning into a flash flooding event during the overnight hours with significant flash flooding occurring across portions of Owen and Monroe counties. Unfortunately, one person lost…

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.

Flood insurance in Bartholomew County

If a building in Bartholomew 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.
