Temperatures may be cold enough to freeze but the Ausable Bayfield Conservation Authority are warning residents that it may not cold enough to go out on the waterways.
They say the water may appear frozen on the surface but it constantly breaks up, refreezes, and gets pushed towards the shoreline.
They especially warn people not to walk on ice over Lake Huron as, unlike other frozen standing water, it has moving water underneath the ice, and it is thinner and more unstable.
They say depending on conditions, it can be difficult for rescue crews to respond in the event you are trapped on an ice floe or in the water.
The conservation authority wants to remind residents to put safety first, and to stay way from lakes, creeks, and rivers.
