Thin ice a serious hazard on Winnipeg waterways: city “Ice conditions on retention ponds can change quickly and without warning, creating an extreme, hidden hazard,” said Cuma.“During the winter, water from snowmelt or nearby water main breaks drains into retention ponds.
This winter runoff is often mixed with street salts causing ice to melt from underneath the surface and thin quickly.”Cuma said people looking for fresh air can still use local parks, trails, dog parks and active transportation paths.The WFPS responds to around 200 calls related to water and ice safety each year and encourages parents and teachers to make children aware of the potentially deadly risks of falling through thin ice.Dog owners are also being encouraged to.
