Id like to dig a hole in the backyard roughly about 12x7x3 deep for a pond. What are some of the best ways to go about doing that? And please don't say shovel and spade because I look hella sexy covered sweat and the ladies won't be able to resist : Kidding aside, I prefer not to use any heavy equipments like backhoe, tractor etc. Wouldnt know how to operate one anyways. Can anyone tell me in the first and 2nd pic what is the floor/edges of the pond is made of? Stained concrete perhaps?
