Here is my DYI project from 6 years ago just after completion. The pond is a 9'x8' oval 5' deep. The project was completed by myself with only handtools. VERY challenging build. My house and yard are surrounded by stone walls and is built into a rocky clay hill typical of CT. no materials could be delivered on site. I wheel barrelled 50 bags of top soil, 500 lbs of peet, 3 tons of stone and all the landscaping materiels up hill and around my house to the build. Stones over 150 lbs were moved by flipping them onto my sons plastic sleigh and dragging inch by inch up the hill and over 400 feet to the site. The largest stones weighed aprox 300lbs.
Digging the hole took 18 months and broke two pick axes. i was working 70 hours per week six days as a Country Club chef at the time and only could work a few hours each morning. My wife thought I would never finish. This is my second pond. My house came with a 700 gallon concrete pond/watefall which i restored and stocked with koi and some natives. The new pond was concieved as a place to winter the fish as the old pond was only 20" deep and freezes solid. i will post some pics this spring to show how the landscaping came in. It looks really good but my liner needs to replaced and I am not sure I am up to tearing down all the stonework! EnjoY!
