Wake_newbie “The study confirms many peoples beliefs that the use of boats on lake systems is beneficial.”

No it does not confirm anything of the sort. Maybe you might like to read it again?
“The trial showed that most of the parameters monitored registered negligible or unnoticeable effects on the lake environment.”

No benefit there.

You might be confusing the following two quotes with a confirmed benefit.
“Water skiing may also bring some benefits to the lake, providing mixing and some oxygenation to the stagnant water body. ”
“It is thought water activities such as skiing are beneficial to a lake as this mixes and oxygenates the water.”

“May also bring” Sounds a bit vague don’t you think?
“It is thought” But not supported with evidence. It may also be just a thought, someone had, at some time and sounded good.

My thought would be that a power boat on such a large body of water would have a negligible effect on oxygen levels and little impact on blooms.
