I've never ice fished Pierce lake but I've fished it in the summer quite a few times. It's not bad, but does not have the fish that Shabbona has by any means. The problem with Shabban is that it can be a difficult lake to learn because of its size and it varied structure. With that said, it produces very good crappie, good gills and nice walleye (for some people, just not me..LOL) at a pretty consistent rate. The other word of caution is that due to geese and currents, ice can vary in thickness quite a bit too, so be careful when you're out. If you want some specific spots to try, I would try the deep trees straight out from the bait shop (30-40 FOW) the cribs along the shoreline in front of the cabins, and my personal favorite, the entire length of the old road bed, but especially over the old road bridge.
