Snow depth increased by 11.5 cm and snow water equivalence by 23 mm since Jan. 2 and is considered normal for this time of year at all sites, reports the North Bay–Mattawa Conservation Authority which measures snow depth and water content as part of its Flood Forecasting and Warning Program.
“Average snow depth is 25.9 cm (normal), and average snow water equivalence is 55.7 mm (normal) for all sites,” said Angela Mills, NBMCA water resources specialist. "In 2024, the average snow depth for the three sites was 26.1 cm and snow water equivalence was 48.0 mm at this time of year.”
