Jumping in here just a year late, but I wanted to share this if it helps others looking for the source of their leak, and at their wits end like we have been. I empathize with you. We were successful in finding our leak source after a lot of trial and error and almost a year of frustration. Many thanks to TJ for his expertise and advice in our process. We found a large hole in the very bottom of the pond. You can see for yourself what it looks like in the video. We are considering our options on the best way to try and fill this hole 18’ under water. The pond is currently about 4’ low. Open to suggestions if anyone has experience with this. We are waging war on this leak and considering all options short of draining the pond at this point.
