Selected from the Digital Public Library of America's 23 image records catalogued for this county. Every one shown here carries a public-domain status or a licence that permits reuse on a site that carries advertising; non-commercial, share-alike and restricted images are excluded. The selection is spread across the county's towns (at most eight per town), so no single institution's bulk upload crowds out the rest. Each opens the holding library's record, and the complete set at the Digital Public Library of America is one click away.



Flown by the U.S. Geological Survey between 1937 and 1989, the Aerial Photo Single Frames collection is the definitive mid-century view of the land: fields, roads and rivers as the camera saw them. The Survey holds 826 frames inside the rectangle that bounds this county; the 28 frames below were taken over the county itself, chosen across the decades of flights (at most four a year from that rectangle), so one flight cannot crowd out the rest. The full set is free to browse and download at EarthExplorer under the dataset Aerial Photo Single Frames.




























The thermometers that kept this county's weather, and the gages that measured the flow of its streams, as the federal records hold them. The extremes below are measured values from those records, not estimates.
Who lived here in 1950, one enumeration district at a time, as the Census Bureau described each district. Each row opens its official National Archives result, with Population Schedules and ED Maps available there.
Every Sanborn volume opens with a printed index naming the town's mills, tanneries, hotels and works by proprietor. Those indexes were read off the scanned sheets by machine and then matched to each other, so a business surveyed four times appears here once, with the years it survived. 4 of these 41 were named in more than one atlas. Each carries a crop of the line it was read from: the spelling is the recogniser's and the 1880s lithographer's, and the scan behind it is the proof.

| May 2011 | Flash Flood | Hicksville | $250,000 | Emergency management officials reported flooding and flash flooding across much of the western half of the county. The Hicksville Community Hospital had water flowing into lower portions of the structure, requiring sandbagging. Laboratory areas were flooded, but the sandbagging efforts kept any water out of patient areas. Several roads were closed through the county, including U.S. 127 near Mud Creek, which quickly went over its banks. Video footage from a newspaper reported showed three to six inches of water flowing from a golf course pond into the intersection of Carpenter and River Roads. Exact damage figures were not available, but flooding damage across the county is estimated around $250,000. |
| May 2010 | Flash Flood | Hicksville | $250,000 | Local media reported flash flooding across portions of far western Defiance County, mainly from Hicksville to Ney. Water entered the first floor of the Hicksville Community Memorial Hospital, forcing the evacuation of a few patients, as well as power being shut off to the laboratory and radiology departments. County officials reported State Roads 49, 37 and 2 were closed near the Indiana and Ohio state line. The village of Ney sustained heavy flooding as well as Lick Creek flowed over its banks flooding the Ney Community Park, parts of the Jewell Grain facility. Seeds and chemicals had to be moved from the grain facility, with sandbagging being done to stop the flooding. A parked car was submerged under flood waters behind the Ney Oil Company. Standing water persisted into much of the next day. However, evacuations ended within a few hours of the event ending. |

Immediately to the northeast of these poles on the south side of Highway 18, a small barn was blown off its foundation, but was left intact with a farm house across the road suffering some minor roof damage. The tornado briefly lifted, but touched down once again on Openlander Road between Lockwood and State Route 18. The front porch on a home was ripped off as well as a television antenna and large tree damaged. A large barn suffered some minor roof damage. As the tornado skipped a few more times, additional trees suffered varying damage, with a few homes suffering shingle or siding damage. The total length along the broken path was roughly 5 miles with a maximum width of only around 50 yards. |
