The county history of 1908 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 51 fires within 5 miles of Silver Lake between 2015 and 2020, burning about 22 acres in total. 1 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:

• Billerica
• East Billerica
• Nutting Lake
• Pattenville
• Pinehurst
• River Pines

Every fire recorded in Middlesex County

Museums hold 614 specimens collected within 10 miles of Silver Lake between 1898 and 1975: 313 Animalia, 242 Plantae, 47 Fungi, 5 Bacteria, 5 Unrecorded, 2 Protozoa. 12 distinct Species records are shown. Collected by A. C. Mathieson, A. E. Feldman, A. E. Sears 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.
