Snow and Ice Survey


Snow and Ice SurveyDuring winter, SNC samples snow conditions in the watershed twice a month. At each of six snow sampling stations, the depth and weight of snow is carefully measured and recorded along with ground conditions. This information is used to calculate the amount of melt water or potential runoff contained in the snow. The data also helps estimate agricultural productivity, fertilizer requirements, waterfowl populations, and livestock and wildlife survival.

Snow sampling data is also submitted to the Ontario Surface Water Monitoring Centre, which collects the snow survey data from all Conservation Authorities in the province.

Winter ice conditions in the SNC watershed are also carefully monitored. The thickness of the sheet ice is checked when conditions permit.
