My personal largest was 16 inches 2.4 lb caught from Lake Lewisville. I was fishing a minnow at a marina and caught her in 12 foot of water. The largest crappie I have ever seen was caught from White Rock lake which in the Dallas City limits. It was 3.4 lbs and my dad and his friend caught it back in 1972 on a trotline. I was 10 years old and my job was to keep bailing water out of the boat with a Folgers coffee can while my dad and friend checked the lines for catfish. The caught him on a goldfish and my dad keep that fish frozen in the freezer for 3 years. It was likely a lake record but they only fished for food back them and records meant nothing too them.
