Flood Dog Site 001

Other

Flood Dog 001 (FD-001) provides sonic sensor-derived water levels and ambient air temperature every 15 minutes. This sensor is mounted to a pier at the Queen City Yacht Club in Toronto, Ontario and is operated by the community science group Flood Dog Co.

On March 15, 2022 a reference elevation of 1.116 meters above the water line was recorded. Calibrated to the www.tides.gc.ca Toronto Station #13320 (75.1 meters above sea level at a distance ~1.5km away) the FD-001 sensor was calculated to be 76.13 meters above sea level.

Current water surface elevation is calculated from the known sensor height Z (76.13m) minus the current raw observation Z'. For example a Z' reading of .75 meters from the sensor derives a lake water level of 76.13 - .75 meters above sea level; the “surface elevation” of the water is thus 75.38 meters above sea level.
