When I was on vacation in Branson, Mo. at Table Rock Lake the guy that owned the cabins had a big boat dock. There he had a crayfish trap like the ones you buy at the store. He took a bunch of chicken bones, must have just ate KFC. Any ways just throw the bones in the trap and tie a rope long enough to reach the bottom and check it in the morning. When he did this I saw the biggest crawdads I have ever seen in my life. The pincher were like 5 inces and bigger. They looked lke freekin lobster! LOL! Not to mention that there were like 30+ crawdads. Hope this helps!
