We are planning a trip to watts bar in early April. Going after some big Crappie. My uncle has been several times in the past but not for the last 5 yrs. He usually does pretty good but had heard rumors about them stocking hybrids or some kind of fish that has supposedly does harm to the crappie population. Can anyone tell me if this is the case. I kind of dought it but I told him I would try to research it. Any info would be greatly appreciated thanks.
