Calgary — The Calgary Fire Department is reminding Calgarians to stay off all storm ponds. According to the CFD, water levels and currents change rapidly in the winter months which can cause cracks and weak ice, making storm ponds extremely dangerous for skating or other activities. “Calgary Firefighters really like seeing citizens outside enjoying all Calgary has to offer, in terms of outdoor activities, but they really don’t want Calgarians to put themselves and those around them in danger by skating on thin ice,” Carol Henke, Calgary Fire Department public information officer, said in a statement. Storm ponds are part of the City of Calgary’s stormwater infrastructure and are in several communities across the city. The ponds are marked by caution signs around the perimeter to remind people they are prohibited. The CFD says because it’s difficult to assess the thickness of the ice and its ability to hold the weight of a person do not walk or skate on ice-covered storm ponds. “Water covered by ice is extremely cold and can be really dangerous to both individuals and pets who have fallen through the ice, as well as to those who may try to help them,” said Henke. Officials say if you fall through ice into the water: If you witness a person falling through the ice: More information about storm ponds is available on the city’s website.
