Although November temperatures have quickly dropped, officials are warning residents to not test the ice on retention ponds by walking out on them.

Fire Chief Dan Fuller said fire officials checked ice on some of the larger ponds in West Fargo and found the ice to be about 2 to 5 inches thick. Ice that is 4 inches or more in thickness will likely support the weight of one or two people, but a group, even of kids, on the pond ice could easily break.
