I would have to lower it dramatically for it to work, I get an unbelievable amount of water in to this pond during a rain. I did have it lowered for this stunt I tried, it was as low as I've ever seen it....didn't matter one bit, filled back up in about 2 hours. This pond has become nothing more than a storm water retention pond; but naturally the city doesn't think so. Actually they do think so; but don't care.
