That is exactly the problem. The pond is perfectly situated because it is the view from the back of my house. I'm looking at it from my dinging room table as I type this. I could build another one but would barely be able to see it due to terrain, so that is not an option.

I'll look into the soils. I think we can excavate the edge no problem.

Do you seen any major drawbacks to the idea of raising the dam to raise the water level 6 feet or so? Assuming the construction is done properly. All of the sediment and nutrient would still be down there. Is that bad?

Thanks
