Indiana Flooding: Record River Crests and a Week-Plus Without Power
Between August 11 and 17, 2026, severe storms dropped over a foot of rain across parts of central Indiana, pushing the White River past crest records that had stood since 1913. The flooding also triggered a massive power outage crisis in Northwest Indiana, where roughly 68,000 customers were still without electricity nine days after the storms first hit. This post covers what happened, why the river records matter, and what daily life looked like during the extended outage. It also covers which counties took the worst of it and how to prepare for outages that don't resolve in a day or two.
What Happened: Record Flooding Across Central Indiana
Multiple rounds of thunderstorms rolled through central Indiana between August 11 and 17, and they didn't let up much between rounds. The rainfall totals east of Indianapolis were the kind that show up once a generation, not once a decade.
The heaviest totals exceeded 12 inches, with spots like Modoc in Randolph County recording more than 13 inches over six days. That kind of rain sent rivers into territory nobody in the region had seen in over a century. The White River hit 24.93 feet at Anderson on August 14, a new record surpassing 1913's 23.60 feet. It reached 24.60 feet at Noblesville on August 15, breaking that location's own 1913 record of 23.80 feet, according to the National Weather Service's Indianapolis office.
At least seven people died in the severe storms and flooding across the state, including a 58-year-old woman who died after driving into floodwaters near Yorktown on August 14. Her death was one of many documented road closures, evacuations, and water rescues across the region that week.
Knowing what to do the moment a flood watch flips into an active emergency is worth reviewing before the next storm system moves in. A home power and safety checklist applies just as well here as it does anywhere else flash flooding hits fast.
The flooding itself was only part of the story. For Northwest Indiana, the power outage that followed became its own extended crisis.
The Power Outage That Wouldn't Quit
While central Indiana dealt with rising rivers, a different problem was unfolding across the state's northwest corner. Lake County, near the Illinois border, and the city of Gary bore the brunt of it.
By August 21, nine days after the initial storms, crews had restored power to 306,500 customers statewide. Roughly 68,000 remained in the dark, a number that had barely budged for days at a time. Getting a sense of how long major outages typically last helps explain why nine days without power isn't unheard of after damage this widespread. It still feels endless to the households living through it.
Daily life in Gary showed just how disruptive an outage this long actually gets. The city's school district, serving about 4,300 students, had been closed since August 13. Businesses across the area couldn't reopen without power. One salon owner summed it up simply: "We're always in survival mode in Gary... but this is the second week now."
A multi-day outage like this one is exactly the scenario a modular home battery system is built to carry. Refrigeration, lighting, and communication equipment don't stop mattering after day two. A system with real expandable capacity can keep those circuits running well past the point where a smaller backup option would have already run dry.
An outage lasting more than a week isn't the scenario most households plan around, which is exactly what made the river records so notable in the first place.
Why This Flood Broke Records That Stood Since 1913
Anderson and Noblesville both blew past crest records that had held for 113 years. That's a benchmark worth sitting with for a second, since it puts this single week of rainfall in genuinely rare company.
Location | 2026 crest | Previous record | Record year |
Anderson | 24.93 ft | 23.60 ft | 1913 |
Noblesville | 24.60 ft | 23.80 ft | 1913 |
Nora | 21.18 ft | 22.40 ft | 1913 (not broken) |
Muncie | 18.64 ft | Ranked 7th all-time | 1913 |
Nora came close without quite getting there, reaching 21.18 feet against 1913's mark of 22.40 feet. Muncie's river level, meanwhile, ranked among the highest ever measured at that gauge without cracking the top of the list. Together, the numbers tell a consistent story: this wasn't an isolated bad afternoon of rain. It was a sustained, multi-day event across an entire river system.
Nine days without power isn't just an inconvenience. It reshapes how a household handles the basics.
What "Survival Mode" Looks Like After Nine Days Without Power
Losing power for an afternoon is annoying. Losing it for over a week changes the math on almost everything, starting with the food in your kitchen.
Food loss adds up fast. Extended outages mean repeated spoilage of refrigerated and frozen food, not a single missed meal you can shrug off.
Community networks fill the gap. Residents turned to laundromats, charging stations, and informal community hubs just to manage daily needs without power at home.
Older residents faced the most uncertainty. A local organizer noted that elderly residents in particular "don't know who to turn to" during an outage this was drawn out.
Knowing precisely how long refrigerated food stays safe matters a lot more once you're nine days in rather than nine hours. It's a detail a lot of households only think about checking after the fridge has already gone warm.
Which Areas Were Hit Hardest
The flooding and the outage crisis weren't really the same event geographically, even though they happened at the same time. Central Indiana suffered flood damage, while a separate corner of the state absorbed the worst power loss.
Central Indiana flooding hit Henry, Rush, Shelby, Decatur, Randolph, Delaware, Madison, Hamilton, Marion, Tipton, Howard, Hendricks, Johnson, Bartholomew, Jennings, Putnam, Vermillion, Warren, Fountain, and Vigo counties. The scale of the response reflects that reach. On August 15, President Trump approved an emergency declaration for Indiana. That freed up federal resources to support the state's response ahead of a full major disaster declaration.
Northwest Indiana's outages centered on Lake County and Gary specifically, well outside the central Indiana flood zone. Rebuilding after a disaster stretched across these many counties often means rethinking a home's entire power setup, not just patching what broke. That's a shift toward pairing solar with battery backup, more households are considering after events like this one.
How to Prepare for an Outage That Doesn't Resolve Quickly
Most short-term outage advice assumes the power comes back within a day or two. This event is a pretty clear argument for planning past that first 24 hours too.
Backup power that scales matters more here than a quick fix ever could. A system built for multi-day or multi-week use looks fundamentally different from one meant to get you through a single evening. Plan specifically around outages that stretch well beyond a few days, rather than assuming the grid bounces back fast. That's the mindset that whole-home battery storage for blackouts is actually meant to support.
Conclusion
Indiana's August 2026 flooding broke river crest records that had stood since 1913, and it left tens of thousands of Northwest Indiana households without power for more than a week. Build a backup power plan around a multi-day outage, not just a brief one, and know how long your food storage will actually last. EcoFlow's DELTA Pro 3 and DELTA Pro Ultra X are both built for exactly this kind of extended outage.

How long were Indiana residents without power after the flooding?
Some Northwest Indiana households, especially in Lake County and Gary, went more than nine days without electricity. Roughly 68,000 customers were still without power as of August 21, even after crews restored service to over 300,000 others.
Which Indiana counties were most affected by flooding?
Central Indiana counties, including Henry, Randolph, Delaware, Madison, and Hamilton took the brunt of flood damage, while Lake County and Gary in Northwest Indiana absorbed the longest power outages.
Did the Indiana flooding break any historical records?
Yes. The White River hit new record crests at both Anderson and Noblesville, surpassing marks that had stood since 1913. Nora and Muncie both came close without setting new records themselves.
How do you prepare for an extended power outage after a flood?
