I had a pond dug on some vacation property I own. It's 30' in diameter and 4' deep. My question is, what do I need to do to maintain it? There is little water in it right now, but the person who dug it assured me it will fill in with rain and then the melt off of snow in the winter. It's out in the woods, and animals will be coming to drink, so I assume no chemicals should be put in once it's filled, but do I need to run a circulation pump to keep water moving in there so algae doesn't take over in the summer? I can dig a ditch to it and run a line if I have to. Any experience and suggestions would be appreciated.
