I've been doing some extensive research on the process of constructing large ponds. The price of everything seems more than achievable/realistic. The one thing that seems a little absurd is the price of bulk rocks. I did the calculations of all the costs to start a project like this, and rocks make nearly 40% of the total cost if I were to buy from a place like Home Depot. It just seems insane that I'm paying nearly the most for rocks of all things! It's a pretty big project, something like 7,000-10,000 ft3, so it'll be quite a lot of rocks. I was just wondering if there was anyway anyone has gotten loads of rock for a realistic price? Other than digging in your backyard, of course. I don't care if they're not very appealing to the eye, a lot of it would just be filler rocks or for the planned filtration.
