Are there any solutions here that don't involve chopping down the tree? It's a swamp maple, so I am sure it does drink a lot of water. It's frustrating though because the whole reason we dug the pond in the first place is because there was standing water in the front yard. Like deep puddles of standing water. The previous owner foolishly chopped down two other swamp maples in the yard right before we bought the place and once those trees were no longer there, the water started accumulating. I guess that one tree has gotten much thirstier than it was before.

I could fill the hole in and turn it into a rain garden or something, but I had gotten my heart set on having a pond. If anyone has any ideas I would love to hear them.
