#IndianaFloods is the hashtag for the historic August 2026 flooding across eastern and central Indiana, which began with a violent derecho on August 11, dropped more than 11 inches of rain in some counties over three days, and broke a 113-year-old flood-crest record on the White River. At least seven people died, over a million customers lost power in the initial storm, and by the end of the first week both the state and the federal government had issued emergency declarations.
Quick Facts

What Happened
Beginning midday on August 11, 2026, a derecho and successive rounds of severe thunderstorms swept across Indiana, dropping historic rainfall totals in the eastern half of the state. An amateur rain gauge in New Castle, Indiana measured 11.23 inches of rain from 9 a.m. August 11 to 4:30 p.m. August 12; the National Weather Service later classified the event as a 1-in-1,000-year rainfall total at that location.
The water surged into the White River system over the next 48 hours. At Anderson, the river crested at 24.93 feet — more than a foot above the 23.6-foot record that had stood since 1913, and the second river gauge to break its 1913 mark during the event.
Aftermath
By mid-week, Governor Mike Braun had declared a state of emergency and mobilized the Indiana National Guard to support flood-affected communities including Gary, Munster and Hobart. NPR reported at least seven deaths across multiple counties tied to the flooding by August 16; TMZ and other outlets reported that President Trump approved a federal emergency declaration on Saturday, August 15, unlocking federal assistance for Indiana’s response to the storms, damaging winds, tornadoes and flooding.
Utility crews worked through the week to restore power to more than a million customers affected by the initial derecho. Regional and national disaster-relief organizations, including Convoy of Hope, deployed teams to eastern Indiana to distribute supplies and staff shelters as the White River slowly receded.
Cultural Impact
The flooding dominated national weather coverage for the second week of August 2026, with CNN, NPR, AccuWeather, and TMZ all leading with Indiana on multiple days. Because the White River crest broke a 113-year record, coverage repeatedly framed the event alongside the #ClimateChange conversation and the broader wave of extreme-weather stories — including the parallel #Wildfires tag active the same week — that had dominated the year’s severe-weather cycle. Local hashtags like #WhiteRiverFlood and #IndianaFloods trended together, with residents sharing footage of high-water marks, home damage, and rescue efforts across X, TikTok and Facebook.
