I was always told life is full of ups and downs. This is definitely a downer. Just two weeks ago the pond was all but full, water didn't start flowing through the siphon system but was real close. Now 2 weeks later and sub freezing temps the pond is down over a foot. Now the ground surrounding the pond was frozen but is also very dry, really no soil moisture going into winter. I think this is way to much to be caused by wicking alone, am I wrong? It has been 3 years since the pond was this full and it held water then at this level. Wondering if I need to start looking for a leak in the top 4 feet or hope of lots of spring rain and see if it comes back up and holds.
