Micheal, back before the NE G & P forum got shut down there was an interesting thread about a "strange pond" in south central NE with trout in it. The trout were surviving the summer heat there due to a submerged irrigation pipe running through the center of the pond that was kept running and it left cold pocket surrounding the pipe that trout stayed very near too. If you were to run a sytem like Bruce's horizontal aeration system with submered irrigation pipe in the pond before the pumping well water into it this should gaurantee a much larger area of cold pockets during the summer heat. On the flip side running the same system during the winter time could also create realtively warmer pockets that might help improve growth rates. The concept is not much different than an air conditing coil. Thoughts?
