There is a small private lake I fish often near my house, and a spring runs into it in two separate spots. It is supposed to be managed rather delicately by some pretty knowledgable folks I'd assume because the largemouth fishing is superb, but every claims that there is smallmouth in there, the deepest point in this lake might be 40 or 50' does this sound like a condition where a smallmouth could thrive and grow healthy or would these fish be long gone? Btw this is in Northern Tennessee.
