I've had my best luck fishing 21 feet or deeper at Burntstick. Never been skunked but have had some slow days, funny thing is on the slow days is when I catch the bigger perch, biggest being 14 inches. Once you find the depth pound the bottom with a jig and stir up the silt, this will attract the fish, then all you have to do is find what they want. I find maggots work the best but have had luck using minnows, worms and meal worms. Best set up for me has been a small Swedish Pimple with a dropper hook baited with maggots.
It's been a few years since I've ice fished Tay lake but for the most part I only caught tiny perch and 12 inch trout.
Check out Phyllis lake too, it's in the area and has perch and trout, again on the small side but fun when you need a fix.
