And one more thing...........no pic, but I also have a steel valve assembly sticking out about 3' above the water level about where I suspect the deepest point would be. It has the gate valve assembly on it. Just curious; why would this pond also have this? If I understand correctly, wouldnt that mean I have another drain pipe and/or method to drain the pond in addition to siphoning? I have only kayaked out there one time and noted this assembly to be very wobbly. But, I suppose if it is connected to a pipe maybe 15-20' below, that may be normal.

Just a little more loss of sleep while I try to figure out this pond. Beautiful pond, but clearly neglected for many years. Hope to get my aeration system going soon.

Thanks again,
