The county history of 1885 has no passage naming this settlement, which was common for the smaller places. Its township is covered in full.

Museums hold 173 specimens collected within 10 miles of Beaver Dam Station between 1893 and 1974: 153 Animalia, 19 Fungi, 1 Plantae. 12 distinct Species records are shown. Collected by Adler, K. K., Amstutz, K., Bezdek, H. 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 1 working within 5 miles of Beaver Dam Station: 1 past producer. None of them still produces. 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.

Every working recorded in Allen County

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 1048503.
