Can someone tell me if the storm ponds are getting flooded with overflow or just drizzled on.
I wouldn't trust these things, they're not natural bodies of water. I think this reads that you can wind up with pockets of air between the water level and an ice sheet. Sounds both neat and dangerous!

So far the study has confirmed what most municipalities already know — ice thickness on small suburban lakes is not as certain as ice that forms on natural water bodies. It's constantly changing as runoff and drainage water flows through the ponds all year.
"A lot of time the ice covers can be safe," said Loewen. "But if they're safe on a Monday, that doesn't mean they're safe on a Friday.
"And it's that unpredictability that is the cause for concern."
Water moving through the ponds can be warmer and turbulent and melt ice faster, said Loewen. Even if water has frozen all the way to the bottom of a shallow section, channels of water can still cut through it.
Another contributing factor is road salt, he said. Depending on how much is applied to nearby roads and how much runs off into ponds, it can also speed up thawing.
