Well not all of it, where the water was running through the locks there was less or no ice, but some sections were solid with ice about an inch thick. This was in Etruria, Stoke-on-Trent, by the Etruria Industrial Museum. At least it was sunny and out of the easterly wind.
A thaw is due, but then wet weather too. Oh well at least I’ll be able to save on my heating bills!
