An account from the chapter on Dayton city, in the words of 1882.

The county history of 1882 has no passage naming this settlement, which was common for the smaller places. Its township is covered in full.

Museums hold 897 specimens collected within 10 miles of Ohmer Park between 1835 and 1975: 739 Animalia, 89 Plantae, 57 Fungi, 4 Protozoa, 4 Unrecorded, 4 Chromista. 12 distinct Species records are shown. Collected by A JOHN, A JOHN AND W E DUELLMAN, A. E. Foeerste and others. Each is a physical object with a catalogue number, and each entry opens the museum's record. This is what was collected and kept, not a survey of what lives here - nothing can be concluded from a species being absent.

The federal mineral resources record lists 17 workings within 5 miles of Ohmer Park: 12 past producers, 5 producers. 5 still produce. What was taken out: Sand and Gravel, Construction. Distance is straight-line from the map coordinates, so a quarry counted here may appear on a neighbouring settlement's page as well.

The eight closest, with where each one stands in the county. Distances are straight-line, computed from the Geographic Names Information System coordinates.

Matched on this settlement's Geographic Names Information System number rather than its name, so it cannot be a different place of the same name in another state.

This settlement is recorded in the Geographic Names Information System as feature 1067283.
