I have had ponds for several years now. They have been pre-formed plastic ones. But with our clay soil and the freezing and thawing in winter/spring, they keep breaking so when the lower one broke this year we decided to put a liner one in. By doing this I now have about double the area I had before. It is deeper too so I won't have to use a heater this winter to keep plants and fish alive through winter. Anyway here are some of the pics
This is before we added the mulch etc.
