Snrub,
Thank you for your reply and questions. You bring up concerns I had not thought of. My lowest concern is the ease of catching fish. They respond to the fish feeder with reckless abandon.
There is not any natural cover at all. The pond reach full height only about 5 weeks ago and was not clearing until about 12 weeks ago. Now I have close to 3' visibility and the sun is finally getting through. No algae blooms as of yet. The water does not get cool until about 5' deep. I am going to get a submersible and surface thermometer so I can monitor the temperatures better than just taking a plunge every now and then.
As for aeration, I will be using some. I have a little tweaking to do on the aerator. I have designed and built a solar powered aerator but need to set the depth of the venturi to as shallow depth as possible. There is not enough draw to overcome a 4" water column. The components are two 6" PVC pipes for pontoons with two large solar panels with charge controller going to a deep cycle battery. This then goes to a low voltage shutdown and then to a 2000 GPH pump. The pumped water flows through a venturi to draw air into the water and jetted downward to stir up the water column and propel the pontoons in a circle controlled by an anchor. Based on weight calculations and water volume displacement, I only have about 25 pounds of positive buoyancy with the two pontoons.
