This was my spring project. The Pond took about a month off and on of hand digging and moving the massive amount of dirt to complete. The pond measures 12 x 10 and is 4 1/2 to 5 feet deep in one area. We have 35 feeder fish in total. It was a lot of work, but well worth the end result. I have a larger waterfall to install, but I am not sure if I really want to work in cold water at this time of the year.
