The county history of 1884 has no passage naming this settlement, which was common for the smaller places. Its township is covered in full.

The federal wildfire occurrence database lists 20 fires within 5 miles of Lock Seventeen between 2005 and 2020, burning about 39 acres in total. None started naturally. None was recorded as arson. Distance is straight-line from the map coordinates, so a fire counted here may appear on a neighbouring settlement's page as well.

The most recent of them, most recent first, with the day each was reported and the service that recorded it.

Settlements close enough to share some of these fires:

• Gnadenhutten
• Yankeetown (historical)
• Port Washington
• Elm (historical)
• Riverside Park
• Rush

Every fire recorded in Tuscarawas County

Museums hold 509 specimens collected within 10 miles of Lock Seventeen between 1851 and 1973: 407 Animalia, 69 Plantae, 31 Fungi, 2 Unrecorded. 12 distinct Species records are shown. Collected by A. Perry, Allen, John, Bethel E. 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.
