Vmaz, I have a neighbor that does commercial construction. We had one of the equipment operators on one of his jobs come over and do some work for each of us with rented equipment. I had a local excavating service do the addition and the other land clearing.
He is in Zion's crossroads but does a lot of work in the Cville and culpepper area. He was slow but meticulous. Happy to give you his name.

Essup, given the 1/2 acre pond size, I was trying to balance the numbers to give me an opportunity to be able to catch several bass when I walk down to the pond. As much as I would love to have several trophies swimming around, it does not sound fun to chase the same 3 few fish until they are hook shy. I am happy to catch 2 to 3 lb bass with one larger on occasion with lighter tackle. Given limited capacity, if I went to 20:1 or 30:1,
What size bg should I expect? How much do you think I would be limiting myself on lmb numbers? I am happy to feed. Closest power source is my barn about 100 meters up hill.

Thanks again for everyone's input. I appreciate the ability to learn from past experience and knowledge vs expensive experiments
