How we rate

Start from how common the DNR says the fish is (abundant 7.5, common 6, present 3.5). Add 1 if the DNR stocked it in the last 5 years, 0.6 for walleye in two-story or complex lakes, and up to 0.9 for lake size. The DNR counts bluegill, perch and crappie together as panfish, so they share a score.
