TL;DR: Emergency officials ordered mandatory evacuations Thursday night, Aug. 13, 2026, for neighborhoods along the Whitewater River in Dearborn County, Indiana, and Harrison, Ohio, and opened public shelters in Lawrenceburg and Harrison.

Mandatory evacuation orders spread along the Whitewater River on Thursday night as river water rose into neighborhoods in southeast Indiana and southwest Ohio. According to WCPO reporting on the Dearborn County Emergency Management Agency, Hamilton County EMA and the City of Harrison, residents in mapped flood-prone streets were told to leave immediately and move outside the evacuation area. According to Cincinnati Enquirer reporting, the orders covered parts of Dearborn County just west of Hamilton County and parts of Harrison along the river. Shelters were opened the same night at 505 Bielby Road in Lawrenceburg, Indiana, and at the Harrison Community Center at 300 George Street in Harrison, Ohio.

The orders marked a sharp escalation after a day of rapid rises upstream. Emergency managers described the flooding in Dearborn County as unprecedented, warned that water could move swiftly and rise rapidly, and urged residents not to delay departure to gather belongings. The National Weather Service in Wilmington kept areas along the Whitewater River under a flood warning until 2:11 p.m. Aug. 14, with several structures reported flooded from Mound Haven to Cedar Grove to New Trenton.

Where mandatory evacuation orders applied Thursday night

In Dearborn County, Indiana, the Dearborn County Emergency Management Agency issued a mandatory evacuation order Thursday night for people living along or immediately adjacent to the Whitewater River, according to WCPO.

The county order named Longnecker, Pinhook, Cranes Run, Barber, Bonnie Lane, Herberts Lane, Cobblestone Court, Stonefield's Lane and Loia Creek Lane. The agency's message, posted just after 8 p.m. Aug. 13 and summarized by the Cincinnati Enquirer, added that it applied to anyone along the Whitewater River in Dearborn County. The wording was broad by design: if a home was on or directly next to the river in the county, officials said to treat the order as applying to that household.

In Harrison, Ohio, and nearby Hamilton County response areas, officials issued parallel evacuation alerts Thursday night. According to WCPO, the City of Harrison evacuation alert covered Campbell Road from State Street to Featherwood Drive, State Street for approximately the first 20 homes north of the Campbell Road intersection, Featherwood Drive from Campbell Road to Whippoorwill Drive, and the corridor along Lawrenceburg Road down to Suspension Bridge Road.

Hamilton County Emergency Management Agency staff confirmed a mandatory evacuation for residents in Harrison along the river because of the flooding threat, according to the Cincinnati Enquirer. A social-media post from the agency said residents along Lawrenceburg Road down to Suspension Bridge Road needed to evacuate immediately. A Hamilton County alert sent at 9:05 p.m. Aug. 13 warned of dangerous flooding, said flood water moves swiftly and rises rapidly, and told residents not to return until directed by local officials.

Households on Flintstone Drive between Featherwood Drive and Whitewater Drive were told to be ready to evacuate, according to the Cincinnati Enquirer. That standby notice meant residents there should prepare to leave quickly if water rose or officials expanded the order.

Where to go: shelters, shuttles and pets

For evacuated residents, a shelter was established at 505 Bielby Road in Lawrenceburg, Indiana. The location was listed by the Dearborn County Emergency Management Agency, Hamilton County EMA and local newsrooms tracking the Thursday-night orders.

In Ohio, the Harrison Community Center at 300 George Street in Harrison was opened for people needing shelter, according to the Cincinnati Enquirer. WCPO reported that people who needed transportation to the Lawrenceburg shelter could go to the Harrison Community Center, where shuttles to the shelter would be provided.

Hamilton County EMA said pets were welcome at the shelter, according to WCPO. The Cincinnati Enquirer also summarized Hamilton County guidance telling residents to take pets, use caution while driving, and not waste time packing personal belongings.

Households that evacuated were advised to move to a safe location outside the evacuation area rather than waiting nearby to see whether water receded. Officials emphasized leaving immediately once an address fell inside an evacuation area.

Why officials acted: river levels and flood warning

The evacuation decisions followed rising water upstream and a forecast for additional rain. The National Weather Service in Wilmington said in an X post that historic rises on the Whitewater River at Brookville were expected to cause flooding downstream in West Harrison, Indiana, and Harrison, Ohio, according to the Cincinnati Enquirer.

The river at Brookville crested at 25 feet at 7 p.m. Aug. 13, a level described as within moderate flood stage, according to the Cincinnati Enquirer. A separate flood warning for areas along the Whitewater River remained in effect until 2:11 p.m. Aug. 14, with several structures flooded from Mound Haven to Cedar Grove to New Trenton.

Forecast information shared Thursday indicated that the danger period was not over. According to the Cincinnati Enquirer account of the Weather Service forecast for Harrison, showers were likely after 10 p.m. Thursday with a possible thunderstorm, and new rainfall of between a quarter and a half of an inch was possible. Showers and thunderstorms could then return Friday in the early afternoon.

That combination — already-high water, saturated ground, flooded structures upstream, and more rain possible overnight into Friday — is the pattern emergency managers watch when ordering evacuations before roads become impassable. Residents were warned specifically that flood water can rise rapidly and that driving conditions could change quickly.

A day of fast water upstream: Laurel, Connersville and Metamora

Communities farther upstream along the Whitewater system had already spent Thursday dealing with rescues and road flooding. According to WCPO, evacuations began Thursday morning in Connersville, Metamora and Laurel as floodwater rose rapidly.

Emergency management officials said that as of 10 a.m. Thursday morning, at least 25 water rescues from homes had occurred in Laurel, according to WCPO. The Laurel Volunteer Fire Department said Thursday morning that residents were urged to evacuate and shelter at the community center. The department said on social media that Jackson Street in Laurel was seriously flooded, with water described as currently chest-deep.

In Connersville, officials said the local flood stage is 14 feet, but the river had already topped 22 feet within about the prior 24 hours, according to WCPO. The town saw more than a dozen residents receiving assistance from rapid and flowing water, with no reported injuries or deaths at that time. One resident told WCPO the flooding was unlike anything seen in decades.

On Wednesday night, Metamora Volunteer Fire officials called for people in low-lying areas of Metamora, Cedar Grove and other areas along the Whitewater River to evacuate as the National Weather Service predicted water levels would rise six feet above flood stage early Thursday morning, according to WCPO. Lt. Andrew Roberts said crews had spent the day preparing to respond to water rescues for people who did not heed the warning. He said people accustomed to seeing the river come up to a yard should expect water to go much farther, even into houses.

Those upstream events help explain the Thursday-night orders downstream. Water moving through Franklin County communities travels toward Dearborn County and Harrison, so rescues and road flooding upstream often precede evacuation decisions downstream.

State emergency declaration and what it means for households

Indiana Gov. Mike Braun declared a statewide disaster emergency Thursday to strengthen the state's response to severe storms, flooding, tornadic activity and a derecho earlier in the week, according to WLWT reporting. The declaration was intended to allow the state to mobilize resources to where they were needed.

For households, a statewide emergency declaration does not change the immediate instruction in an evacuation zone. The instruction remained direct: leave now, go to high ground or a designated shelter, and do not reenter until local officials say it is safe. Residents with storm damage in Dearborn County were also given a separate reporting path by local emergency management for later damage-assessment surveys, but officials said life safety was the main priority Thursday night.

Household readiness checklist for river-flood evacuations

Officials did not ask residents to pack extensively before leaving. Hamilton County guidance summarized by the Cincinnati Enquirer said to take pets and not waste time packing personal belongings.

For households in the named streets or anywhere immediately adjacent to the Whitewater River in Dearborn County, the practical steps Thursday night were:

Leave immediately if the address was inside the order. Do not wait to confirm water at the door, because officials warned that water can rise rapidly after a crest upstream.

Use the designated shelter if no other safe housing is available. The Lawrenceburg shelter at 505 Bielby Road and the Harrison Community Center at 300 George Street were the public options identified Thursday night. Shuttle transportation was available from the Harrison Community Center to the Lawrenceburg shelter, according to WCPO.

Bring people, pets, medications already at hand, phone chargers, identification and a way to receive alerts. Do not make extra trips for nonessential items.

Avoid flooded roads and do not drive around barricades. Local emergency resources deployed to the area completed several rescues Thursday, and officials repeatedly warned against entering flooded roadways.

Stay out until cleared. The Hamilton County alert said not to return until directed by local officials. Returning early can place households on isolated roads if water rises again overnight.

Keep monitoring official channels. Hamilton County EMA said information for Hamilton County residents was being posted on the agency's social media, with more information and updates to be posted on the agency's website, according to the Cincinnati Enquirer. Additional rain was possible overnight and again Friday afternoon, so orders and road closures could change.
