Ottawa fell from 4,460 to 4,456 between 2010 and 2020. These are the recorded population figures Wikidata holds for this place, reached through the Geographic Names Information System number this page is keyed on rather than by name, so they belong to this place and not to another of the same name. Most are census counts, but not all are: an early figure may be a founding or settlement estimate, and an estimate published within five years of a census is left out. The change column is computed, and is left blank where more than 20 years separate a figure from the one before it, because a gap that long is not a change between two counts.

Matched by testing this settlement's coordinate against the published boundary of every sheet in the United States Geological Survey's historical collection. Each opens the scanned sheet at the Survey.

Regional context, not property-specific evidence. The federal wildfire occurrence database lists 4 fires within 5 miles of Ottawa in 2002, burning about 3 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:

• Green Acres Estates
• Upper Tauwa (historical)
• Glandorf
• Pandora
• Spring Lake Village
• Columbus Grove

Every fire recorded in Putnam County

Regional context, not property-specific evidence. Museums hold 103 specimens collected within 10 miles of Ottawa between 1860 and 1969: 95 Animalia, 8 Plantae. 12 distinct Species records are shown. Collected by Adler, K. K., Blyth & Katz, Bureau of Fisheries 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.

Regional context, not property-specific evidence. The federal mineral resources record lists 3 workings within 5 miles of Ottawa: 2 past producers, 1 producer. 1 still produces. What was taken out: Limestone, General, Stone, Crushed/Broken, Clay. Distance is straight-line from the map coordinates, so a quarry counted here may appear on a neighbouring settlement's page as well.
