The pond is flowing well and with the extra ice cover, it acts like a blanket especially with snow covering. It was cold again last night and there appears to be more ice than yesterday. It did melt quite a bit on Sunday but now we seem to have the cold weather back again. But with the water flowing from pond to pond, as soon as another nice day comes the pond breathing holes get larger. Right now it is minus 12 Celsius (10 F) and all appears well. With the snow falling over the ice, this will act like a blanket and the water under the ice and snow will warm up and the breathing holes get larger with the addition of snow covering the ice.
Have to go outside and check things out and will get some pictures and post later.
