This one was dug and filled the fall/winter of '16, so it's still just a baby. So far, the only unwanted visitors I've had were a couple of 2' gators which were promptly persuaded to leave. I'm only 1/4 mile from a bayou, and while I know there are a few otter around, so far I think the fence and my three dogs have done a good job of policing the property. Time will tell. It'll be interesting to see what it does this winter. The 4' visibility I had was just recently, during our 10 week drought. Lost about 20" of water, but it's full again now that we got a bunch of rain. Still, it didn't muddy up at all and visibility is around 2'. Hoping to have aeration soon.
