Thanks for the responses. We fished in the late afternoon.

I don't think either pond had much structure, but would the fish still hang out near the structure even if it is in shallower water? The little reading I have done says that they'll leave the structure in the winter to go to the deeper water.

What surprised me most is that I didn't mark any fish on my fish finder. Is that common? I understand there are days they just don't bite, but I've still had days where I at least marked fish. Could it be possible that they somehow died out?

I'll have to see if I can get some grubs. We're supposed to have temps in the 50's this weekend so I'm guessing it's "bye-bye" ice fishing for this year.
