I am probably the only person to have a wtf koi pond. I think the reason the liner is pulled up is that Deborah, the previous owner, bought a 24 inch deep liner and then was told that the koi would need at least a 36 inch depth if they were going to "over winter" successfully, so she sort of folded it in half and stuck it in a deeper hole. The other theory is that she didn't buy the "geothermal liner" that is supposed to cushion and provide an escape route for methane and other gases that build up under the pond as things decay under it, and pulling up one side vents it. In either case, the koi will either go to my neighbor's koi pool in the back, or back to the shop for winter; the pond will get redug and relined, and have frogs and goldfish instead. And water lilies.
View of kid paradise next house over, from my dining room. Not shown: trampoline, Scooter the dog, 7 children, flaming chiminea or James, age 8 with his airsoft gun and dirt bike. I am hoping that eventually James will be interested in mowing the front lawn, once I get grass to grow on it.
And finally, a cat in a box!
