How Crawford County floods

Flash flooding driven by heavy rainfall dominates the local flood profile, accounting for 48 of the 64 recorded flood events over the last 30 years, alongside 16 general flood events. Recent documented events include a historically strong low pressure system that brought heavy rainfall and strong winds in March 2023, and repeated rounds of excessive rainfall totaling 8 to 9 inches across southern Indiana in February 2018, which led to significant river rises and numerous flash flood reports including road closures. Remnants of Tropical Storm Gordon also produced efficient, flash-flood-inducing rainfall in September 2018.

National Flood Insurance Program records indicate the heaviest concentration of claims occurs in Zone A with 91 claims averaging a $21,210 payout and an average recorded water depth of 9 inches. An additional 35 claims are cataloged in Zone UNKNOWN, averaging a $9,584 payout with an average recorded water depth of 4 inches. Properties located in Zone A and unmapped or unknown zones should pay the closest attention to flood preparedness, given the heavy concentration of historical claims and flash flood events driven by regional storms and tropical remnants.

Where the flood claims came from

6% of Crawford County’s flood insurance claims were on properties rated outside FEMA’s high-risk zones.

97 NFIP claims with a recorded rated flood zone, 1978 to date. The zone is the one FEMA used to rate that policy, which may not match today’s map. Source: OpenFEMA NFIP claims.

From the storm reports

Flash Flood · Mar 3, 2023. On March 3rd, 2023, a historically strong low pressure system moved across the lower Ohio Valley, bringing heavy rainfall, severe weather, and most notably, very strong gradient winds as it moved across the region. On the synoptic scale, a shortwave upper-level trough located over the mid-Mississippi Valley became negatively tilted during the morning hours of March 3rd. A 120 knot 500 mb jet developed across centr…

Flash Flood · Aug 18, 2020. While on the western side of an upper trough, a surface low with associated fronts moved south through southwest Indiana. This produced heavy rainfall with localized flooding in a few Indiana counties.

Flash Flood · Sep 25, 2018. On September 25th a saturated air mass was in place ahead of an advancing cold front, with precipitable water values near two inches. With this air mass and shear ahead of the cold front, convective showers formed over southern Indiana and advanced east along Interstate 65 causing flooding issues in the system's path.

Flash Flood · Feb 24, 2018. Repeated rounds of moderate to heavy rainfall across the entire Ohio River basin totaled between 8 to 9 inches across southern Indiana from February 15 to February 28. These totals were generally 7+ inches, or 200 to 400% of normal values for mid to late February. The large areal extent of the excessive rainfall led to significant rises on area rivers, including the Ohio River. This resulted in numerous flash floo…

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 Crawford County

If a building in Crawford 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.
