How Scott County floods

Flash flooding from heavy summer thunderstorms and stalled frontal systems dominates the flood risk profile in Scott County, Indiana. Over a thirty-year period, the NOAA Storm Events Database recorded 18 flash flood events compared to 4 general flood events. Significant episodes include a slow-moving front in December 2015 that dropped 1 to 3 inches of rain on saturated grounds, and a stalled cold front in July 2021 that produced isolated wind damage and flash flooding along the Interstate 65 corridor. Additional widespread heavy rainfall occurred in February 2018, when totals of 8 to 9 inches led to significant river rises and numerous flash flood reports including road closures.

Federal flood insurance data demonstrates that financial losses are concentrated in specific hazard areas. Properties in FEMA Zone A account for the highest average payouts at $30,480 per claim with an average recorded water depth of 2 inches, followed by properties in Zone UNKNOWN with an average payout of $8,619 and an average recorded water depth of 3 inches. Properties in Zone X recorded lower impacts, averaging $938 in payouts with an average water depth of 0 inches. Homeowners and real estate agents in Zone A and unmapped or unknown zones should pay the most attention to flood risk and mitigation.

From the storm reports

Flash Flood · Jul 12, 2021. On July 8th, a cold front dropped south through southern Indiana in a saturated environment. Even with moderate instability and shear values, severe thunderstorms were able to produce wind damage across southern Indiana along the Interstate 65 corridor. In the following days, the front stalled and remained in the area causing isolated wind damage and flash flooding in the same part of Indiana.

Flash Flood · Jun 26, 2018. On the second day of heavy rain across southern Indiana, a quasi-stationary boundary was draped across central Kentucky. As a system moved east through central Missouri. storms moved in from the west. These storms resulted in many reports of wind damage as well as some flooding.

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…

Flash Flood · Dec 27, 2015. A slow moving front combined with very moist air from the Gulf of Mexico resulted in moderate to heavy rain with some thunderstorms during the morning hours December 27th. This rain, which totaled 1 to locally 3 inches, fell on top of already wet and saturated grounds from recent heavy rainfall events, produced localized flooding and flash flooding for portions of the area.

Flood insurance in Scott County

If a building in Scott 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.
