I have a giant hole on my property dug by the previous owner, it's about 115ft x 70ft and maybe 9ft deep. The problem is that they dug it on a hill so the 3-4ft of water that does accumulate in it only lasts for a couple months before it's dry again. I would like to turn this into a year around pond, I've looked into a pond liner but I don't have over $3,000 to spend on this project. Does anyone have any suggestions that won't cost me an arm and a leg?
This link explains what gleying is and how to do it yourself if you do not have any animals to help you out right now. In essence, gleying is the creation of an anaerobic seal on the bottom of a pond through anaerobic decomposition.
