Recently I was talking with some friends and we were all wondering about how old a walleye will get. Take an average fish on a lake like Mille Lacs. I know a 12-14″ fish is probably 3 years old, or so I’ve been told. Is this roughly accurate? How about your 28-30″ fish? I know there are a lot of variables, and that there are all kinds of exceptions, but generally how old would an average fish have to be to get to that 28″+ range?
