Nashville is 36.16 latitude; Eads is 35.15. That's a pretty significant difference. I don't know if I-40 is the best way to judge whether a species of fish will thrive in a pond, since I-40 goes through both Memphis and Nashville, and obviously one is significantly south of the other. One of the lakes I know of that has had TS do well is in Dickson, which is 36.08, almost identical to Nashville. The bass in that lake are northern-strain, and they average two pounds or better even though they're crowded (I don't manage the lake, would like to but wasn't asked); in one day last summer I lost four of the biggest bass of my life in that lake. And Eads is south of I-40 anyway.
Regarding correcting a bass-crowded lake, I could see how it might take years to do so if the lake were dozens or hundreds of acres; with a 3.5 acre lake I personally feel that the only way it would take years is if ineffective methods were used, i.e. fishermen who aren't skilled doing the harvesting, or not stocking additional forage, or a combination of the two. I would wager a lot of money that I could catch enough bass from Layne's pond in one day, two max, to get it on track. If additional forage were stocked concurrent with or soon after the removal of bass, he could see a significant difference in the average size of the LMB as soon as next summer. Just my $.02.
