Indiana faces flood risk from the Wabash, Ohio, White, and Tippecanoe rivers, as well as urban flash flooding in Indianapolis. The Wabash River, Indiana's longest river, regularly floods its broad valley affecting communities from Terre Haute to Lafayette to Peru. In 2008, severe flooding along the White River caused extensive damage in Indianapolis, with the city experiencing its worst flood since 1913. The Ohio River creates significant risk for southeastern Indiana communities, with Lawrenceburg, Madison, and Jeffersonville experiencing repeated inundation. Flash flooding is a growing concern in Indianapolis as urbanization increases impervious surfaces. The 2008 Midwest floods caused over $1 billion in damage across Indiana. The state continues to experience significant flood events every 2-4 years. Indiana has over 600 NFIP-participating communities and has invested in flood mitigation through the Department of Natural Resources Floodplain Management Program. Flood risk is expected to increase with climate change-driven intensification of rainfall events.
