I don’t know the lake but I do know you are very unlikely to catch them in the same location you do during the warmer months. The rainbows you may catch shallower during low light feeding times but the panfish I’d go a little deeper, checking basins near structure or drop offs with some vegetation. Best strategy I’ve found for that type of ice fishing is moving around with a flasher until you find them schooled up. Sometimes it’s a matter of feet.
