I'm most intrigued by the tables on page 17. They show (for this lake that sounds similar to Ovid in being a shallow, small lake) that in July and August there's almost NO temperature gradient and a very small DO gradient. Certainly both gradients are much less than what I had expected.
Is this lake different from Ovid in any significant way that would effect these data relating to similar conditions in Ovid? IOW, would Ovid be substantially the same?

– there is generally a significant difference from a lake like Manistee (natural spring fed) and a man made lake like

What would the T and DO gradients be like in Ovid in the summertime?
I wouldn't expect them to be nearly as uniform in Ovid because of the limited light penetration at most times. HOT on the top and cool near the bottom would be what I would expect. Along with the limited light penetration you'll get less oxygen because the weeds aren't going to produce as much. Therefore I would expect the deeper (12+) water at most times will have DO levels that aren't comfortable for muskies.
MMA should find someone trained in experimental physical science to study such lakes scientifically. Apply for Gummint funding to buy an appropriate floating portable aquatic transportation system and large aquatic fauna "sampling equipment" together with the requisite temperature and DO measurement tools to study these things in detail.
I have some very interesting ideas along these lines… [smilie=brows.gif]
When Tonello released this Manistee Lake report it caught my attention for the Eurasian weevil management tool. I'm working on a local weevil project in Muskegon County and use other lakes as education examples. Then I noticed the lake and fish data and thought this would be educational fun for MMA to study and pass the winter evenings. I respect the way the Spoonpluggers and MMA take the time to study the lakes.
The large sucker population is easy to note, but I thought the pike population and size would be larger in the samples. I was probably too quick to jump to judgement. Snippet: "Although only 12 individuals were caught in the 2004 survey, they represented seven different year classes and were growing well. The presence of a 36 inch pike in the 2004 survey shows that Manistee Lake is capable of producing large northern pike." Stock muskie is the natural response for MMA, but could this lake be managed for CPR trophy pike?

Based on the Tonello's study Manistee Lake (Kalkaska) would be a perfect lake to add muskies. If they are considering a removal of suckers why have to struggle with it again in ten years? Why not start stocking muskies?
I like your way of thinking!!! I was entertaining the same idea! Sounds like a perfect candidate for muskies. [smilie=2thumbsup.gif]

That was a tongue in cheek commnent. I know the reason why… they would trickle down into trout water. MMA vs. Trout Unlimited would be like Lassie vs. Godzilla.
