Stay off all local stormwater facilities no matter how the ice looks. There are no circumstances in which the ice on stormwater facilities is safe. The surface may appear solidly frozen, but stormwater continues to be released underneath the ice due to snowfall, snowmelt, road clearing and salting operations. Runoff entering the pond throughout the winter typically contains concentrations of salt or warmed water, which can thin ice surfaces rapidly and may not be evident from the surface. There may be a sudden unforeseen rise in the water level, resulting in unsafe conditions. The structural integrity of the ice will be compromised due to voids between the water level and the ice.
Stormwater facilities are not ever safe for recreational use (sledding, skating, walking) for a number of reasons:
