Snow depth increased by 14.0 cm and snow water equivalence by 29.3 mm since January 15 and is considered normal for this time of year at all sites, reports the North Bay-Mattawa Conservation Authority who measures snow depth and water content as part of its Flood Forecasting and Warning Program. 

“Average snow depth is 39.9 cm (normal), and average snow water equivalence is 85.0 mm (normal) for all sites,” said Angela Mills, NBMCA Water Resources Specialist. In 2024, the average snow depth for the three sites was 19.7 cm and snow water equivalence was 52.3 mm” she added.
