Mike, our pond is 1/4 acre when full, and only 7 feet deep. I don't aerate during the summer as the incoming irrigation water is cool and well aerated.

Yes, the splashes of feeding trout are exciting. I'll pull out my cell to snap pics; water from 15 feet away can drench the lens. One of my Australian shepherds likes to hang her head over the edge of the dock watching the fish. She'll get a soaking on occasion.
