Thanks, everyone for all the information. I wish that I had known about this forum months ago. But it is not too late to be helpful. I just found out last night that the pipe is already through the damn. It's galvanized (wish I had known to insist on PVC) and runs straight through the dam and nearly parallel to the water surface at maximum desired water level. Bobad, your suggestion should be entirely possible, although it would have been much easier to fabricate if the pipe had been PVC. I had not considered that it might not be smart to move deeper water in the middle of winter. Will have to research that.
To maximize water that is roughly 6' deep, I have carved out the sides of the pond. I am a little worried about controlling erosion at the relatively steep edge. Is there a preferred groundcover that might help hold these edges.
Below the surface, these shelves extend out a ways ending at a ledge adjacent to much deeper water. That was my understanding of the recommendations to create ambush points for the bass. I will add structure to the edges of that shelf and plan to use the 5-gallon concrete bucket anchored to angle iron system. Does anyone have other recommendations or "artificial" structure? Again, I am very grateful for the assistance. Tom
