Brad, is your lake a strip mine? What kind of watershed do you have? I'm guessing that in your area it is a mine with little runoff to have that clarity. The large amount of plants may also act as a filter. Have you ever had an oxygen temp. profile done. The western lakes with trout and tropy bass have always made me curious as to if this would work in the midwest. I have some pond clients in the Mt. Vernon area, and will be visiting in Feb. I would love to send you some literature. Hopefully someone can give you some fertilizer advice if it is an option.
Thanks,
