Brettski, sorry I forgot to answer your question about the pond seal. I wouldn't be too worried about drilling in the limestone because it's not solid ... just chunks and rocks here and there in the soil. But I don't think drilling will be necessary. The part of the pond that has water in it is holding water good and I don't want to take any chances. I've already put a few hundred pounds of bentonite in the bottom and banks too.
Schroeder, that is exactly the type of benches I had in mind, I'll have to check out those brackets.
I don't have electricity out there so the wood will need to be cut with a chainsaw. I'll also have a cordless drill out there.
