It may be to early in the summer to tell right now, but my water temps seam to running a little cooler than the hot days last year. I am running the diffusers at night only this year or 9 to 9:30. My pond will not be near as deep as Brians and I would think the deeper water would be cooler than mine at 12' depths.
and Frank, if you try out the stakes with blue or white tarps then the lmb should come out of the shade when a bait is thrown at the edge or side of the cover. I would think if u set the tarps a foot or two above the water the wind movement might help to cool. I think it can work but might take a bunch of tarps to see measurable decrease in temps.
