Snow's Secret: How Meltwater Fuels Canada

Much of Canada experienced substantial snowfall recently, with some regions setting new winter records. This extensive snowpack has significant environmental implications, particularly regarding water resources. Snowmelt is a critical component of Canada's fresh water supply, contributing between 40% and 80% of the stream flow in rivers and lakes.

This natural replenishment process is generally beneficial for water systems. However, snow from urban areas often contains pollutants such as road salt and chemicals, posing a risk if it enters important water supplies. Experts are also monitoring the potential for flooding, especially in areas like Southern Ontario, following heavy snow followed by warm rains. While large amounts of snow are common in places like Northern British Columbia, significant accumulations present logistical challenges for urban snow removal operations.
