Max depth is about 15' but there's a lot of 3-8' depth in the majority of the water. We don't have aeration but I am considering getting a solar powered set up. There is no spring feeding it but we have a large watershed that keeps the pond close to full volume except for an occasional strong hot/dry period of long duration. Over the 18 years or so I've lived here, the pond may have dropped up to 2 or 3 vertical feet at most maybe three times.
