Tested the ice yesterday in hopes of clearing off some to get O2 in the pond... in order from top down... 4 inches of old granular snow 2 inches of loose frozen slush 1 inch water 2 inches of frozen slush 4 inches of water or more. Indefinite amounts of hard ice! Probably only a few inches
Needless to say I near pooped myself when drilling and layer 1 broke through to layer three. amazed at this after all of the cold weather I assumed solid, but just too much snow.
The fish will just have to suffer down in the dark.
