August 2026 Ohio Flooding: What Homeowners Need to Know About Cleanup and Insurance

What Actually Happened This August

Ohio averaged 6.88 inches of rain in August 2026, about 198.5% of what's normal for the month, which the State Climate Office of Ohio recorded as the highest statewide August precipitation total on record. Columbus logged 9.94 inches, its second-wettest August ever measured. Dayton wasn't far behind at 8.73 inches, also a second-wettest-August mark. Zanesville had its wettest August since 1896. What makes the swing sharper is that August 2025, just one year earlier, had been dry enough to raise drought concerns for Ohio farmers — a reminder of how quickly Ohio's weather can flip from one extreme to the other in back-to-back years.

Two Rounds That Did the Damage

The worst flooding came in two separate rounds rather than one continuous storm. Overnight on August 10 into August 11, Perry and Morgan counties took five to eight inches of rain in a matter of hours, enough to push local creeks and the Moxahala Creek watershed well past their banks. A second heavy round moved through on August 19 and 20, dropping another 6.1 to 6.8 inches on Franklin County alone, on top of ground that was already saturated from earlier in the month. That one-two pattern is a big part of why the damage got as bad as it did — the second round had almost nowhere to drain.

Where It Hit Hardest

Perry County's Crooksville and Roseville took the brunt of it. Both towns were largely cut off by rising water at points during the event, with roughly 380 residents displaced and homes in the Rose Farm area among the hardest hit. A state of emergency was declared for Perry and Muskingum counties, and the broader event affected Morgan, Fairfield, Licking, and Franklin counties as well. Multiple tornadoes were also confirmed across the storm's various rounds — the National Weather Service office in Wilmington alone confirmed 16 on August 11, with additional tornadoes confirmed by other NWS offices on separate days. By late August, Ohio's confirmed tornado count for the year had reached 44, roughly double a typical year's total.

These figures come from Governor DeWine's formal disaster declaration request and state climate reporting; see the sources linked throughout this page to verify current numbers, since damage assessments are sometimes revised as more properties are inspected.

Is This Covered by Homeowners Insurance?

This is the question that matters most, and the honest answer is: it depends entirely on where the water came from, not on how bad the storm was. A standard Ohio homeowners policy generally covers sudden, accidental water damage from an internal source — a pipe that bursts under storm-related power loss, or a roof that a storm tears open, letting rain in from above. What it typically excludes is floodwater: water that rises from the ground, overflows a creek or river, or backs up from a storm sewer overwhelmed by rainfall. That kind of damage requires a separate flood insurance policy, most often through the National Flood Insurance Program. For the full breakdown of wind-versus-water coverage rules and why wind-driven rain gets special treatment, see ClearFlow's guide on storm damage and Ohio insurance coverage.

Ohio's NFIP participation has historically been low, well under 1% of homes statewide, which means a large share of the homeowners affected by this event likely have no flood-specific coverage at all. If that's your situation, don't assume you're out of options — a disaster declaration, if approved, opens up other forms of federal help that don't require a flood policy.

What a Disaster Declaration Would Actually Mean

Governor DeWine submitted a formal request to FEMA in early September 2026 covering 23 Ohio counties. As of this writing, the White House had not yet approved or denied it, so treat this section as informational rather than a guarantee of assistance, and check for updates before assuming anything is available. If approved, a Individual Assistance declaration typically opens up FEMA grants for temporary housing and essential home repairs not covered by insurance, along with low-interest disaster loans through the Small Business Administration for both homeowners and renters. None of that replaces filing a claim with your own insurer first for anything your policy actually covers — federal disaster assistance is generally meant to fill gaps, not duplicate insurance payouts.

What to Do Right Now if Your Home Flooded

1. Get everyone out safely first, especially if water is still moving or rising. Floodwater a foot deep can knock an adult off their feet, and it's not worth the risk to grab belongings.
2. Photograph everything before you touch or move anything, once it's safe to be on the property. Wide shots of every room plus close-ups of the waterline, damaged flooring, and any visible mold growth give your insurer and any disaster-assistance application a clear baseline.
3. Call your insurance company the same day to open a claim, even if you're not sure yet whether the damage is covered. Filing promptly protects you either way, and an adjuster can help clarify what applies to your specific policy.
4. Start extraction and drying as soon as possible. Mold can begin colonizing wet drywall and flooring within 24 to 48 hours, and floodwater is typically treated as contaminated (Category 2 or 3) water, which changes what can be cleaned versus what needs to be removed. See ClearFlow's guide on Category 3 black water damage for what that distinction means for your home, and our day-by-day guide to preventing mold after flooding for exactly what needs to happen in the days right after the water goes down.
5. Board up or tarp any storm-created openings — a torn roof section or a broken window — before the next round of rain finds its way in. See our guide on emergency board-up services in Ohio for typical costs and response times.
