We try to keep it at 12-18 inches. The pond is spring fed with a large watershed. It sits between two rises. Heavy rains pull bad water off the bottom very well. The kids jump off the dock almost daily in the summertime. We also exercise about 10 German Shepherds with a dummy launcher off the dam. All of this activity seems to keep fresh air pumped into the pond. At least thats what we hope!
